Quarter mile?

how fast would a stock 93 H22 prelude run in the 1/4?

around 13 sec's...

i'll say low/mid 14s

high 15's I would say

I'll say a compromised number between everyone... 15 to 15.5. :wink:

hey yall im new to this forum thing and i was wonderin if n e one wants to talk? i have a 2000 2 door honda civic ex

What? If somebody wants to talk...go to a chat room, meet people in your neighborhood...

Oops and the prelude with close to perfect conditions will run mid fifteens 15.4-15.6

Actually, I wasn't guessing when I said 15 to 15.5 ...

how fast would a stock 93 H22 prelude run in the 1/4?

Man if you can find a stock prelude with a H22 running the 1/4 mile in 13 seconds I will kiss your you know what! whoever stated it is more like 15s is probably very close to being accurate and must be speaking from experience. Besides who wants to run an all stock Vtec H22 in the quarter anyway? Would you not at minimum have a cold air intake and or exhaust modifications, a NueSpeed shortshifter for short moneyanything to provide you the best bang for yoru buck would be a great improvement over stock? They sound so much sweeter with a good aftermarket exhaust system why on earth would anyone take the challenge of running the quarter mile in a stock lude? Your 1/4 mile time would only add fuel to the fire for downing import tuning by the 8 cylinder heads

Some people don't have the 700-800 dollars to drop on quality parts. After I do my h22 swap, I plan on being broke, and I'm sure the stock H22 will hold be over for the time being. Actually, it wont be stock because I will need certain parts that do not come with the motor, and they will most likely be aftermarket. In any case, not everyone is made of money.

Certainly did not want to imply that everyone has money nor do I think that you need to drop a ton of money into your car to improve it. In fact if you read my reply it states to get the best bang for your buck. Meaning if you are on a budget like all of us should be than you invest your time and money wisely especially into a car. However, I would not be concerened about the 1/4 mile for a stock Prelude. The info provided by some was incorrect 13 seconds is next to impossible for a stock Prelude 4th or 5th gen. If yuo are on a budget there is plenty information available to even make your own cold air intake for under $50...also you can invest into an aftermarket exhaust system for under $300 that will provide you fantastic sound and perfromance without having to buy headers. You are welcome to email me and I will email you lots of info for 4th gen ludes for us who do respect budgets.....but please dont run the 1/4 mile totally stock you will make life worse for all of us who lhave a passion and love for our imports. I am 52 and a converted muscle car and BMW owner who lives in the deep south were we are constantly facing the doubters of imports. Mustangs, Camaros are a dime a dozen here. But my son who is now 19 introduced to me to his first 1992 SI that we converted to a JDM H22A 5 speed and we have had lots of fun together making muscle heads eat their words. You should have seen how embarrassed a 40 year old in a mustang gt was when my son left him 2-3 car lenghts behind.

Anyway email me and I will galdly email you back with ideas that can provide you the most bang for your buck!

I understand what you are saying, I was just emphasizing the fact that most of us here are pretty broke. However, I say that if you want to run your car at the track, by all means, do it, stock or not. It's good experience.

It's also nice to see a dad listening to his son. I keep telling my dad that there is potential in these cars, and he doesn't really listen until he rides around with me in it. He's been musclehead his whole life though, so I don't blame him.

I don't know about down south, but everyone has imports where I live and it gets a little sickening. It's nice to see a muscle car blow the doors off some rice burner every now and then. There's a certain feeling of torque that you just can't really get with a 4cyl. motor. I do respect you for holding your own where you live though. I get doubted quite a bit too.

Welcome to the board! It's nice to get some relatively 'older' people in here that are as enthusiastic as we are. Thanks for the email offer, but I have some pretty good ideas of my own. :smile:

i kicked the shit out of an '88 Chevy Camaro z28. just my :2cents:

Personally, I think that cars like the Prelude feel most at home on a course rather than a drag strip. There is nothing at all impressive with being able to go in a straight line really fast. All out dragging is not our fight.

I am impressed by a very fast car on a drag strip. I wouldn't go so far as to say nothing is impressive. It's more of a matter of the car being powerful instead of a good driver. I do agree though, that preludes were meant for the corners and that's where they really shine.

I like both......I also own a 1993 Lude that has ah H22a with lowered suspension and qauffie lsd, with cornering and handling that was equal to if not better than a 1974 Porsche 914 6 set up for slalom. However, my son ran 4 times at the strip and after we installed the lsd it elimated most of the wheel hop and he turned in a respectable 13.2 time. Not bad for basically stock naturally aspirated JDM H22a. But I would love to build a 10 second Prelude. Shepard has a first gen DSM AWD that runs 8.67 seconds in a 4 banger. Needless to say this has convinced me that 4 bangers can be more than respected on the 1/4 mile track as well

DSM's have one very important thing over us: its drivetrain. We can strap on a turbo and run those high psi's, but the FWD design limits dragging quite a bit. Not that it can't be done, of course...

do you know what the fastest time for a street driveable 4th gen Prelude is? Can you share with us what they have done to achieve a street driveable 4th gen prelude that is both a 10 second car on the strip and can still handle remarkably well on a slalom course? My son and I are at odds he thinks that you build a car for either one or the other. I think you can take the same upgrades used for a 10 second 1/4 mile car remove the front racing slicks and have a fast excellent handling touring car that is responsive at low, medium and high end through corners and straightaways. Your imput would be greatly appreciated.

beaudeg, Im sorry man but your full of sh*t. I prelude with an LSD WONT RUN low 13s not even with Fittipaldi or Shumaher on the wheel. It is not possible. If you said, he ran a respectable 14.7 I wouldve probably would believe you...But 13.2 common man...thats just mmm so stupid.

Kinda getting anoying...too many people smoking crack and shit while they post things on this forum.

I really dont want to use this forum for a pissing contest. Why dont you invest some time and read some of my other replies posted in this forum. It is evident that from my postings that I have invested time in my responses and come from facts not fiction. Yes, my 1993 Prelude with a JDM H22A initially ran 13.7 before adding the lsd and after eliminating most of my wheel hop she ran 13.2 best time. IN fact I will be more than happy to put some serious money where your mouth is. I live outside New Orleans and my son ran this car in Gufport , MS racetrack. Not sure where you live but would be glad to pay for your entire trip here if this car does not run between 13.2 and 13.5 consistently. Here is the deal I will pay for your roundtrip to and from New Orleans , put you up in a hotel and give you $1000 cash if this car does not run between 13.2 and 13.5. When we demonstrate and meet the 1/4 mile times above you pay for your entire trip and pay me $1000. Put up or shutup! I dont post shit to impress you or anyone else. I also own a RED 1993 Fairly stock H22a4 with headers, exhaust, nology wiring, msd ignition, stock rims and tires, neuspeed shorts shifter with fidanza flywheel, and am acr extreme street clutch and pressure plate that can beat 14.7 in the 1/4 mile. So where did you come up with 14.7 as more realistic and the balls to acuse anyone on this forum or insult me. I am enjoying this forum and adding/sharing information that is helpful to others. If you want or are devoted to maintaining a high degree of quality than please revisit your criticism. Anyway hope you take me up on this offer and show the members of this forum how quick one can be at the stroke of a keyboard to make false accusations. Come on MAN! Cant wait to show and confirm a real high degree of integrity!!!!

unless you have FI, no2, or a built block, you are not running in the 13's PERIOD. we may be amatures here, but we know our preludes. thus we know you are lying. you're car runs high 14's, if you even own one. i want to see time slips, video, pics of the motor, and a dyno. or if you don't wanna do that, i'd love a free trip to new orleans.... or better yet, let's bet you 13.2 sec prelude. i always wanted a beater.

p.s. are you sure you're not running 1/8 miles?

sure! No one stated that you or members of this forum are amatuers. If you know your Preludes than why would you doubt my car runs in the 13s. You obviously are oblivious or naive to think that are 4th gen preludes run high 14s or even 15s.Your comments are really not worth responding to but I am up to the challenge. What I have in my H22A was never mentioned/discussed. so read my reply more thoroughly " I also own a 1993 Lude that has ah H22a with lowered suspension and qauffie lsd" " basically stock" Not runing NO2!There is no mention of what internals I have. You were just quick to label people as liars and full of shit! This must come from a person who has nothing else to do and strut around as a rooster stating hurtful and insulting accusations that are unfounded.

What do you have to bet against my 93 running in the 13s? I will gladly run the 1/4 mile against something you own of equal or greater value which I doubt you own since your cars run in the 16s and obviously are not worth betting against. But I tell you what.... book your trip to New Orleans for a Wednesday night arrival that is when the Gulfport Ms, track is open to all categories and bring your titles since we will have to bet for moire than just one of your cars. If I dont run in the 13s consistently in four runs you can have my car and title and drive her home. Either step up to the plate or own up to being a pompous ass who has nothing to offer but criticism of others.

p.s. are you sure you're not running 1/8 miles? A beater? yes this 4th gen prelude car which happens to be one of 4 I own plus 3DSM's a 1998 Integra Type R with a B18C engine with a P28 Custom programmed ECU are all owned by this same person who you accuse of being a liar and who probably does not even own a Prelude happens to be the proud owner of not only the 93 in question but all of the above also. The only non naturally aspirated engines are in my DSMs.
Let your friends on this forum take a look. I even took a picture of my license plate and number so you can clearly see there is nothing to hide and the car that will run your a.. out of town and off this forum will be the same car with this license plate and LA title to match. You can view my pictures here please note dates they were taken....so get down here and we will end this conversation once and for all. By the way I never stated this engine was stock I said "basically stock" since I am not running turbo or superchargers

ok, lets look at the facts. you have a "basically stock" vtec lude.

motor trend/road & track tested 14.9-15 1/4 mile time (pro drivers)

you dis people for not have intakes or exhaust, so i asume you have that.

i/h/e 14.9 down to 14.7 (if that)

lowered suspension=no gain

lsd (which i have) = 14.6 (if that)

ok..... so we have 1.4 seconds to lose yet.

1.4 secs = gutting 1400 pounds out of you're car (not likely)

1.4 secs = 140 more horse power (tell me how)

1.4 secs = 13.2 sounded better than 14.6, so i made it up


No one stated that you or members of this forum are amatuers.

i never said anyone stated that. DON'T put words in my mouth


If you know your Preludes than why would you doubt my car runs in the 13s. You obviously are oblivious or naive to think that are 4th gen preludes run high 14s or even 15s.

i say that, b/c i do know my preludes


There is no mention of what internals I have. You were just quick to label people as liars and full of shit!

if you have enough internals to gain 140 hp, i would think they deserve mention.

I stand corrected! I just spoke to my son because of this frustrating dialog we have been having. He corrected me and confirmed his best time in 4 runs was 13.7 not 13.2. Still a second faster than you think is the best time. You quoted road and track as 14.9-15 for a stock 4th gen lude. Do you have the time for a 4th Gen with a H22a built? Maybe just maybe I am not so full of shit and you need to learn to get more details before jumping on someone especially in a public forum. Oh yea did you get a chance to check out the pictures of one of the many cars I happen to own since you dont think I even own one? Please check the date for posting as they were taken and posted during this heated discussion.

ROFL.... you went from "basically stock" to "H22a built" BUILT WITH WHAT. tell me (for the 3rd time). what is in this glorious motor. if you next post doesn't state EXACTLY what "built" means, i will no longer waste my time with your bs.

This could all be avoided with an initialed time slip..

Beu man.. you have to expect a little criticism on these forums if you claim something and don't back it up.

Its Beau! French meaning in English is Friend. I was introduced into this Forum and imports by my son. I am a friend to this new discovered forum. Normally avoided them thinking that this enabled public criticism. I was afraid to post a response to a guy who is experiencing the exact sounding issues we had with an H22A upgrade from an auto/si h23. When you have a chance this forum allows us to look up a registered member by user name. Check out my response I believe that I have the answer for him and it is proably much easier than her thinks. Anyway I won a small shop in La. and built this 4th gen Prelude from scraps found in local junk yards and some investment made from the net. I have purchased and sold a shit load of cars, trucks and parts via the net and basically enjoy the excitement of building, planning designing kick ass cars. Mostly into imports now and would have continued to be an american classic muscle car builder but cant find the same excitement for an american muscle car anymore with the exception of a 1968 - 69 Camaro SS. Also take a look into my member photo gallery I believe that I have posted adequate proof of my sincerity. A signed timeslip I dont have but Iam proud of the 4gen lude we have created. Not only is it sleek and very stock on the shell she is a sleeper. The only thing that makes her noticeable to tuners is her sound and aggressive low stance. Maybe lowering and providing a stiff frame/suspension system does not greatly improve your 1/4 mile,according to your calculations, which is another topic of discussion for later, but at minimum you have to agree it gives her a stock look with a subtle aggressive stance. This baby rumbles and growls close to imports but just a little deeper growl not much unlike a muscle car but different. Come on down and you wil witness this baby run the 1/4 like a scalded dog as they say in Mississippi. If i had the stamped dated and name of track time slip I would have scanned it and posted it. I will be gald to scan in proof of ownership. dont go there because these are facts and it is an insult to request verfication....but I will.......but hopefully we can move on and you can develop a sense of respect and trust that I am a fellow man on this forum and within this world.

Hey, hey.

Props to you, Beau, if your son actually did run that. He must be a very gifted driver, and your engine block must have been built very well. I too have an h22a in my Prelude Si.

Cheers

Oh, and you're not allowed to have those kinds of pictures in the gallery... (although they are very nice :wink: )

Legal Public pictures such as these have appeared on the front cover of national magazines. These pictures were taken in the streets of New Orleans. Glad you liked them I did not realize they are not allowed on this Forum since I thought they are in good taste not porno pictures Have you seen the pictures of SEMA models.....? I would think my posted pictures are no less in good taste.

Send me an email to [email protected] and I will tell you what and how we build this guy. I guess basically stock is a misrepresentation I shoull have stated naturally aspirated. However, you saw the pictures does she not look like a stock car just lowered? My son corrected me on this also in the muscle car world this car would be categorized as street stock or modified stock. My son owns and drives one of the DSMs that featured a JDM 4G63 with a big 16 g turbo, head built by dark enhancements, arp head gaskets, bolts, JE pistons, nice polished and balanced crank with blow off valve sounding like a jet taking off with w whilrwind sound as it discharges illegally in to the atmosphere. His DSM is pretty quick but highly unreliable. The blue and white two tone lude was his first car a 1992 Si converted to an H22a but cant touch the green/blue 93 lude. the 92 Si was in a mjor collision during MArdi Gras weekend and we rebuilt her using a JDm clip and painted her a solid candy apple blue with metallic and leather interior. Nice looking but no where near as fast as his DSM nor the 93 lude. He is an expensive son to have around as his hobby for cars is equal to if not greater than mine. Sorry I got so defensive I should have taken your criticism better. Just beat up and touchy after my many years of being in a fast rat race business world.

Take care and hope you have a warm happy Easter. We are off to church but yuor last posting deserved an immediate response. Glad we toned things down and are respectful of each other

I would like to know, in fact. Do send me an email at [email protected]. It's all good, I would have gotten defensive too if someone had called me a liar. And these forums are made so that we can share our experiences with each other... so if there has been a Prelude capable of that kind of timeslip, then damn, I would like to know how he did it.

I used to have a 2nd generation Talon AWD. They are incredible cars to modify for drag use, but like you I had severe reliability problems. My best ET was at 13.6 with mods that added up to less than a grand. The DSM triplets take to mods very well.

I have put nearly 4 grand into my Prelude, and am only putting a little more hp to the wheel than a stock 2G DSM. Of course, due to experimentation, most of my mods have not been the most cost effective.

Keep up the good work. Many of us are skeptical because we have rarely seen a Prelude capable of that kind of timeslip without massive engine work, and there have been many punk kids who come up and give some bullshit numbers.

Oh my God. What can I say...? You keep believing your son ran 13.7 with a almost stock prelude...Ill believe I can beat a modena with my civic SI.

It never ends.

aces, please let us know what he has in it when he email's you. assuming he does.

Oh my God. What can I say...? You keep believing your son ran 13.7 with a almost stock prelude...Ill believe I can beat a modena with my civic SI.

We already established his definition of almost stock was a semi-built motor. There's no need to flame anymore.

Thanks Prelewd!

Hi guys for those non believers...let me just add a few comments. Please notice your own time postings(Mexir) at higher elevation and at sea level. There seems to be a remarkable difference. Remember we live in the deep south and run at a track in Gulfport, MS which happens to be 5 feet above sea level. Mexir timeslips are 16.6 versus 15.3 at sea level. Is this believable or crap? My car ran with 14.4 with a stock JDM H22A and a lowered/dropped suspension. It had wheel hop which slowed our time getting out of the hole. Spent a few bucks and invested lots of time by changing exhaust to DC headers, 2.5 inch custom fabricated exhaust, dc muffler, eliminated cat convertor
(not a problem around here), added aem intake, nuespeed short shifter, purchased 5 angle ported heads from dark enhancements, JE high compression pistons( not running no2 nor turbo nor supercharger) crank was turned and balanced and added a Quaffie LSD with INgalls camber kit front and rear. Out of 4 runs at the same track the best time was 13.7. No it she is not totally stock but probably if this was a muscle car would run super stock/street class. I stated she was basically stock. The block was built to handle higher rpms, stock cv axles, interior is intact has all the creature comforts of an everyday street driver with the exception of the suspension system being pretty stiff but other than that in my mind received very little modifications. No rechipping P13 ECU.

The reason we decided on higher compression versus lowere compression is because we had no intention of running turbos, superchargers or no2. we wanted an everyday driver that had some balls and could handle with accelleration on slalom tracks. This car gives us a respectable time on 1/4 mile but was really built to handle curves, straightaways and banks without body roll or steering torque.

The DSMs we own that are all Turbos have been so unreliable as everyday drivers but are so quick on the track that we wanted to shy away from forced induction. However, we now want to build a streetable 10 second 2nd gen prelude and will probaly go with low compression pistons, no2, turbo or jackson supercharger. However, we still want to make this other Prelude a red 1993 S VTEC into a handling car at low, medium rpms responsive so I posted the question of anyone knowing of someone who build a 4th gen with the acceleration of a 10 second car but without the slow response at lowere rpms than I welcome some feedback.

If any of you are in or around New Orleans come see me and my car. my shop address is 60181 Hwy 11, Slidell, LA 70458. I posted the pictures with GTC MOTORSPORTS clearly on the windshield for all to see. I also included a picture of my LA license plate....nothing to hide just sharing info as I think this forum is and can can be a great place for positive exchange of info......So if you could spend some positive time by sharing anyone who has built a prelude as described above that can run in the 10s and handle as good as my current 93 prelude than I would love and welcome this exchange of information so we could build and design something similar. I will never copy exactly what someone else has done but would like to use this information as the basis before we spend a great deal of money and time to reinvent the wheel.

I was wondering, are you running the stock p13 then? You can probably unlock alot of power by getting a Hondata unit and taking it in for some wideband dyno tuning.

Yes we are it a JDm P13 stock. How much do you think we can unharness? There is also only one shop within the greater New Orleans area that I know of that does a god job tuning on a Dyno and have not been impressed with their work so far. I was thinking of taking her out of state but am concerned about the difference in our environments. We live at or below sea level with temperatures hovering in the high 90s for 6 months and around 90 plus humidity. Can you recommend someone within this area?

It's hard to tell how much, but you WILL be able to squeeze some mentionable amounts of power from the car. Stock p13's are only good for stock car. Look into getting the GSR's p72 ecu and a Hondata unit (www.hondata.com). They have several good tech articles there that are definitely worth a read.

Hmm.. I remember hearing a few bad things about running p72 ECUs on the prelude. I'll try to dig it up tomorrow.

Thank you aceshigh and prelewd. I have been to the Hondata site and just got confused. Since we have a JDM H22a not sure which combination of ecu to use. At their site they list H22A US version. I thought H22A is the JDM version only and H22A1 is the US Engine version. Also is there not a difference not only in the basic JDM H22A engine specs and the JDM P13 specs vs US. I think my stock H22A was 200 HP before modifications fidenza flywheel, act clutch, unothodox pulleys and the stuff listed in prior postings. We have never dynoed this car yet and we are just beginning to understand the complexities of the ECU but the 93 lude runs like a scalded dog as is and can't seem to find technical information on the best combination of a cutom ecu. I was under the impression that the JDM P13ECU would adequately support our internal and external modifications since we are not running no2 nor forced induction. But if we can unleash some serious power through the use of a modified ECU I am all for it.

You have to change all the MAPs on the p72 to match your car. The only reason you don't want to use the p13 is that it isn't compatible with Hondata. Running a stock p72 on a Prelude is dangerous and not smart. I'll write up more on this when I get the chance.
