04 Spec V, SR20DET SWAP???

Hello,
Ive had my 04 SE-R Spec V for about 4 months, and just to tell you a little about myself, I started out in 2002 with a WS6 Trans-Am and added a Jackson Racing Supercharger. After I blew that one up last year, I went out and purchased the 04 Dodge SRT-4 with Stage 2 Turbo upgrades, and many aftermarket mods. My wife rolled it driving to work one day and totalled it out.
As you can see, I am used to very powerfull performance cars. I dont feel right, unless im running 12.0 or better on the track.

So, back to the top... I have this 04 SE-R Spec V, and Im looking for info on making it fast. Now, Ive seen the Spec V forums, and people with insane ammounts of money in mods are barley running 13's on this QR25 motor.

Would an SR20DET swap be a good idea? Any problems? Pro's? Con's? Im looking for a daily driver, that I can put my licence plate back on with pride. IEATV8s

Any info is appreciated. Thanks.

one person has done it and says he's gonna break into the 12s next time he goes to the track. his name is pimpride and he's on www.thevboard.com

you should pm him about it.

get powertech imports stage 2 or 3 turbo kit

is there anyone running a PTI kit yet?
FIR has the most proven bolt on turbo kit...
they have some other good stuff coming in the near future too i hear.

robertsmb, no spec-v owner has ever posted a timeslip of 12.0 though. SR20DET swap is probably your best bet, but why didn't you get another '04 SRT-4 if you're a drag racer?

Sorry guys, I don't know much about cars. But why would you trade in a QR25 over a weaker engine like the SR20??? What is so special about SR20? If it was as good as people make it out to be then why didn't Nissan keep the engine instead of the QR25?

what is fir

In my opinion I would do a complete engine rebuild with strengthen internal components. I know there isn't a rebuild kit for a QR25 that I know of but with enough money you can have all internal parts custom machined. Replace every engine component with high performance ones(valves cam shafts etc...) Don't forget a clutch and a flywheel and get the tranny rebuilt as well. I would recomend to run low compresion so you can run some boost. Get some drag radials too.Leave the body style alone so people wont know what hit them . Either way it is going to be expensive. SR20DET established itself and it fairly easy to get parts for it.The SR20DET has alot of potential don't get me wrong. Before I got my Spec V I wanted a 240SX and I wanted to swap the KA24 for a SR20DET. I did'nt have enough money to buy the 240SX and to do the swap all at once so I got the Spec V because I needed a car. Also that way I can pay it over time. I'm not very patient. A friend of mine has a 89 accord and he can't decide to do a rebuild and go turbo with the A20 or to do a B18 swap. I would do the swap cause the A20 is a SOHC. The SR20DET's advantage is the stock turbo that it has over the QR25 . Strip the SR20DET of it's turbo and you'll see what the engine is made of.I don't know the numbers for a SR20DE so I can't tell you which one is better in my opinion. The QR25 has little more displacement but that really doesn't matter. The stock QR25 isn't the most efficient engine but if you give it a chance it will show it's true colors. It just depends on how fast you want the car to be and how much money you want to spend. If you are worried about emmisions and it being street legal you should you wait untill some one makes a decent turbo kit that doesn't have a turbo the smaller than a doughnut and that is legal.

My SR20DE(not a DET!) FWD runs a 13.04sec qtr without NOS in Australia but I can tell you that a SR20DET will get you into the 12s in OZ would be a aftermarket exhaust manifold feeding a GT30 ball bearing turbo(or similiar) with 18psi, front mount intercooler, 3" exhaust from the turbo back, bigger injectors, MoTeC computer and rebuilt bottom end with forger pistons(8.0:1 compression) which with the right clutch / flywheel combo and a tranny capable of handling the estimated 400hp at the flywheel, should get you pulling 12s in no time

Check your local laws around engine swaps, too. In some areas, it's illegal to swap in a motor that is older than the car.

the true limits of the QR25de have not really been tested yet. If you want proven HP potential.. I would say the SR20det is a great idea.

If money isn't too tight.. throw down $2500 on a SR20det from Japan and have fun.. For most of us.. money is limited so we need to be more creative..

Let me throw out another idea for you...



KA24de. The KA is an iron block designed for use in truck originally. Because it is very torquey, it turned out to be a great engine for small cars. So Nissan put it in the 240sx in rear wheel drive format and the Altima in front wheel drive fashion. I have more experience with the Rear drive as I am now on my second 240sx. But the engine is the same in either car. I am not sure how the mounts sit in comparision between the old Altima and the Sentra. But, I would guess they are usable.

Here's what's cool about the KA. It is very strong. People in the 240sx world argue all the time about whether the KA with a turbo is better than the SR even after all the upgrades. So far.. the KA has been proven to show higher hp without internal modifications. I have seen reports of almost 400HP.

I am not sure how strong the front drive tranny is on the KA..

The reason I suggest this is .. KA engines are cheap and easy to find. I bet with $500 and a pickup truck to load one into you could come up with one in a heartbeat. So for the money, you can get a lot more out of a KA than either a QR or SR.

just an idea...

dude i have a turboed qr25de and i spank sr20det all day long. that bottom end and that displacement is the better buy. there is no turbo lag on my qr25de. u can get so much more out of ur qr25de and its more reliable

wrong. a boosted SR20 will always have a bigger power potential and more reliability than a boosted qr25. its just built better. the qr is built as basically a replacement for the ka24. true if you stuff forged things into a qr, and remove the balance shafts, stock cats, and reinforce the cylinders, you can get more power, but thats putting a lot of money into it that you dont need to put into an SR to make power.

i only boost 8psi and i get more power to the wheels, my cousin has a 240 with the det swap and he cant compete with my sentra. the det is a good motor and strong but there is no turbo lag with the qr25de the displacment works really good with my turbo. and if u turbo a car u better be willing to spend money thats with any car and the qr25de is more reliable if u just want a basic bolt on kit

I would swap in a VQ35DE. Big V6 that takes boost better than a QR25 and runs high 12s without turbo.

quit dragging dead threads up with the same "i got a turbo" comment, i doubt you do cuz you sound like a fucking idiot and even if you do you still sound like a fucking idiot so please quit crapping in our forum

Wow, I skimmed to the bottom too fast. I didn't even notice that douche.

why u got to get mad, and i do its just funny listening to all u guys talk about this and that when u dont even know the half of it. i worked for nissan for 6 years and i now have a shop. i go to all the nhra events i can and the drits so act like u know everything. i do have a turbo and and i will say again, sr20det cant match up with me and have proven it time and time again so untill somebody proves me wrong i will always say the qr25de is better. thats why i bought the sentra and not a 240..

OK then. :popcorn:

you worked for nissan for 6 years and still thought a turbo was your best bet on the qr25? guess i was right

wow exactly. either hes lying out of his ass and is actually a 16 yr old kid who thinks hes cooler than he is, or else hes just a retard. everyone's grandma knows that the qr is a fragile motor. i wanna see one, ONE make it to 200k. STOCK. i know people who run highly boosted SR20s to 200k without a problem. shit theres even a kid who has a 350whp KA24, COMPLETELY STOCK internally, with over 150k on the odo. and he drives it daily, and races it all the time.

get out of here with your retarted logic. the purpose of sentras has and always will be a mess of a car thats much faster than the sum of its parts. theres no pretense suggesting otherwise. not from nissan, not from nissan tuners.

trust me i know more than you will ever know.
isnt 6 years kinda long to work as a lube tech for a dealer?

buuuuurn.....

u know what u guys might be right or not but like i said until i get proven wrong by one of u de guys it wont matter what u say and why would i put 200k in my car and its only a 05 so i cant really find out till a little later. plus if u guys actually were racers and not just like everybody else that goes to there local straighta ways with the same people every weeken u would no that ur car shoulded be a daily driver thats why people always mess up there turboed cars and everybody thinks just by putting on a turbo kit u are fast and all this blah blah ! i have spent a lot of money and time on my car and i do go to all the nopi and nhra events not just to empty straight away on saturday night with all the other losers!! its funny how u guys talk crap about me working at nissan when i bet your job is lame as hell and talk really good crap on a computer. i bet that makes u feel better, i guess u have to make up for other things

im am captain of a regional auto cross team in mid florida, i could beat your ass through a road course if i was running on four doughnuts and a warped headgasket, or in reverse if you wanted to look really stupid, ive got more driving talent in my left foot than you do in your whole family

i worked for nissan for 6 years and i now have a shop. i go to all the nhra events i can and the drits so act like u know everything

N/O, but you should have spent a little less time at Nissan and a little more time in English class. I'm not trying to be a dick... but I am one, anyway. Sorry, that street talk just pisses me off.

I WiLL RACE YOU ANYTIME MOTHERFUCKER, IM JOHNNY TRAN.... A.K.A THE COOKIE MONSTER NUCCA, I GOT TO ALL NHRA EVENTS INCLUDING THE DRIFT ONES AND WIN THEM IN MY JDMTYTEYO TURBOSUPERDUPERCHARGED SENTAR!!!!! WITH THE MAD VTEC POWAH I PWN THE SR20!!!!!!!

1st off: Not all of us want to be "hardcore racers".
2nd: You really need to learn how to write at least at a 3rd grade English level
3rd: There is nothing wrong with working at Nissan, and you have no idea what we do for a living. I'm only 21 years old, and I have a quality control position for the largest distributor of platics in the midwest. I'm an unofficial supervisor for people who have been working in my company for over 30+ years... However, I don't give a shit about my job, because I'm only going to work for my company for two more years, until I'm done with college, which you obviously know nothing about.

This is a car forum, not a job forum. Trust me, I doubt you want to go head to head with what people on this site do for a living, unless you want to feel stupid. So go ahead now and tell us about how you make 100k a year at your super important job being the CEO of your cheese sandwich factory, how your fucking a super model, or how your spec v can pull 8 seconds on the track, with just street tires, because no one gives a damn about what bullshit comes out of your ignorant mouth. I won't even reply, and I doubt many people will, because no one wants to hear you.

Good luck at NOPI, or w/e, speed racer.

well that was really fun, i got a lot of response from everbody. see what i tell u people start talking shit when someone comes along and just challenged them a little. and for all those people that said that they will smoke me all day long and have so much talent in there left foot, thats all i expected from u guys. and why would it matter what i do for a living now all i know is what i have done to my car and and my life. everybody in here must not really have a life but to talk all this shit to somebody they dont even know. yes my grammer sucks but english isnt my first language, i am still learning. and somebody really wants to race and talk crap in person then they can come up to sothern cali and hit me up. i was just putting what i know out there and like i said i might be wrong but i atleast i can admit to that and if u want to know i will let u know exactly what i have done to my car. sorry i dont drift not my cup of tea so dont be saying all this "i go to all the drift events and i win and blah blah blah" i dont car, drifting is cool but not for me. sorry everybody thinks all this stuff i say is retarded but its not my fault u can t handle any word exchanges. maybe i should go talk to the honda guys atleast they aint little girls and run there mouths over a computer

F&f Ftw

your right. go over to the honda guys. youd fit right in. all they ever talk about is how big their automotive nutsack is anyways. or maybe you should go over to the biggest perpetrators of baseless e-thugging and shit talking forum there is: the camaro or 5.0 forums.

Hey guys, I just bought an 03 SE-R Spec-V, i wrecked my 98 Mitsubishi Eclipse RS with the Mopar 420a engine. Running 5psi boost on custom turbo setup, i was haulin at 120 with a local street crew and swerved onto an offramp and started spinning, i spun about 5x and started sliding down the L curb and took out 2 signs, I told everyone else to haul ass NOW, I'd be ok.. The wrecker called the police. The police ticketed me for "striking field objects" $200 fine, and thats all... I thought the Spec-V was a good tuner car at first but now that ive learned the truth about the engine, ime wanting to either do a VQ35DE swap mabey with a turbo kit, or i am looking into the SR20.. I live a mile from Houston Raceway and Park, my best 1/4 mile was 15.7 in my Spec-V.. I could have bought a Honda CRX with a fully built b20. Price was $6666. The seller claims he runs 9's.. He says its too fast for a daily driver.. I am currently working @ Sears Automotive, been workin there 1 1/2 years. I am rather inexperienced, but I'me learnin more and more as I hang around these cats @ the racepark.. I'me thinkin of sprayin a 55 shot on this QR25DE engine.. But then again not the best idea..:smokin:

i hope your not serious. a treadstone turbo kit and your in the 12s provided you can drive.
