SR20DET for drag racing

I was once told that if you have an 240SX and you plan on drag racing it, it would be best to keep the stock motor and turbocharge it rather than to swap in a SR20DET. Is that true? I would have thought that the SR would be a good engine for drag. I also heard that the SR motor is only good for drifting. I cant honestly remember why. This sucks for me because I wanted to use my SR for drag racing. Can anybody set this straight. Im sorry if this is a dumb question but I had to know.
Thanks
Luke

Yep, you've got the concept right and its been covered a million times.

Basically just use common sense for your answer, why swap out 2.4litre for 2.0? The KA makes more torque and power, hence people says its better used for drag. The SR on the other hand is a bit less powerful but lighter and tends to rev higher, hence drifting. Just search around, everybody and and their momma knows the answer to that question on this board.

But don't let that stop you, I bet the rolls can be reversed. I'll try my hand at KA-T drifting once i get my bastard Eclipse sold...

The main reason for using the KA-T for dragging is that if you blow it, you can pick one up at the junk yard for 200$, if you blow your SR, that's a 6month wait and 1000$ down the drain.

No. Noone has ever made power with the SR EVER. at 180WHP the Cylinder Bores start to Distort and the motor blows.


The KA on the other hand can make 1100WHP on the stock bottom end but you'll have to be the first to try it since theres not much aftermarket support.






































Seriously Man, thats about the most weakass question I've ever seen. Tell me how an engine would be good for drag racing and I'll show you many that dont fit the mold. Show me how an engine would be good for Drifting and I'll show you cars placing first in D1 with the exact opposite. do what ever you want to do and if you can find someone fool enough to let you drive a car with one of those motors base your oppinion on that.

The SR engine has gone faster, and produced more power to date than the KA engine in an S-chassis.

This is not saying the KA is a bad choice or a bad engine! So for all you KA lovers out there don't light the fuses on your tampons just yet.

What is your budget?

Odds are the KA will go faster for less. This is simple logic, especially given that you are new to the 240 scheme of things.

My next question is how far are you willing to go? What do you want out of the car?

Give me some background of your automotive knowledge as well as what I have asked above.

The main reason for using the KA-T for dragging is that if you blow it, you can pick one up at the junk yard for 200$, if you blow your SR, that's a 6month wait and 1000$ down the drain.

Bullshit, I had a SR longblock to my house for $300 in 1 week after I popped my first engine.

You just need to get off your ass and make an effort to know people.

SHOULD be better for power... the SR Record is still a good 350HP more.


The SR on the other hand is a bit less powerful but lighter and tends to rev higher, hence drifting. Just search around, everybody and and their momma knows the answer to that question on this board.



Case in Point again. SHOULD. where V-8s are allowed (ie Formula D) they stomp down.

True, but this guy is obviously clueless to the S-chassis world.

yea well same thing

Agreed.

I don't think he's wanting to drop V-config engines in there, I was just refering to the KA vs. SR in particular. oh shit, i said ka vs. sr............... :eek:

I don't think he's wanting to drop V-config engines in there, I was just refering to the KA vs. SR in particular. oh shit, i said ka vs. sr............... :eek:

Yeah well those without either ... should not talk.

Kthnx.

I don't think he's wanting to drop V-config engines in there, I was just refering to the KA vs. SR in particular. oh shit, i said ka vs. sr............... :eek:


Its still just as Relavent. Bigger displacement is stomping down

thanks for all of your replies and some of you are completely right-- I AM NEW9 and clueless) TO THE S CHASSIS WORLD!!! ive been on here before and i couldnt find the answer to my question. im sorry for not searching hard enough. thanks for all of your help and i hope that alot of you guys are there to answer any other questions that i might have later on.

Yeah well those without either ... should not talk.

Kthnx.

don't be an asshole, just because i don't have either doesnt mean I don't know anything about them

oh shit!! i didnt mean to say that i already had an SR motor!if you guys would have told me thatit would be good for drag than ok, but seriously, thanks for setting me straight guys.

don't be an asshole, just because i don't have either doesnt mean I don't know anything about them

Gathering from your commentary it doesn't sound like you actually do know anything about them.

thats what we're here for.......i think, haha

Gathering from your commentary it doesn't sound like you actually do know anything about them.


Oh gawd, now my knowledge is being tested, I just wanted to give him the simplest answer, not all this what if crap..damn

Oh gawd, now my knowledge is being tested, I just wanted to give him the simplest answer, not all this what if crap..damn

Your answer was incorrect is the point.

and hows that

sorry im going to have to take xeven's side on this one. not on the knowledge part but seriously elitist, you need to stop talking shit for no reason. he didnt say anything to you. if hes mistaken then correct him. dont be a fucktard with an attitude. your name might be elitist but you sure dont come off as elite.

i didnt mean for this to be a flame war! blame me for all of this and call it a day?huh?!

and xeven, thanks for that reply. im happy that there are people like you who are there to help people like me no matter what!!

Basically just use common sense for your answer, why swap out 2.4litre for 2.0?


This is an arbitrary and completely false statement.

Displacement is mearly one of the aspects of an engine. It is not the solves all to the solution.


The KA makes more torque and power


The KA does make good torque, and good power, but it does not make MORE torque and MORE power just on it's own right. Again another blind and arbitrary stab at the situation.

It has yet to outrun the SR in terms of potential, as mentioned several times already in this thread.


The KA makes more torque and power, hence people says its better used for drag.


Ever heard of gearing? Again refer to my ideology above concerning your first comment.


The SR on the other hand is a bit less powerful but lighter and tends to rev higher, hence drifting.


Little bit less powerful compared to what... yet ANOTHER arbitrary comment.


Just search around, everybody and and their momma knows the answer to that question on this board.


Evidently not. There is no simple answer to a complex question.

Your arguement is superficial and lacks supporting evidence other than what is socially accepted on this board. Try backing up your commentary with evidence that is factual and not hear-say.

yea its cool man you didnt do anything wrong, just read around before you ask questions cuz chances have it that someone has asked it before. Oh and don't worry about the hostility around here, we fight so much we oughta be brothers and sisters, lol

he is l33t as sh!tz0rs.


but seriously FUCK V*'s in D1 and FD its some bull ass shit. i dunno its true they do well. besides rhsy millen i think they are shit though. i saw the Mopar Viper and it was the gayest thing ever. there was a lot of tire smoke through the run but his average real speed through the course was probably 15-20 MPH... just one slow, carefully plotted and steered, over-extended burnout! not drifting!! ugh i dont even know what to think about Gushi in the mustang, havent seen it in person yet, but id rather see him in something else.

i hate to take the stand of being a purist, saying the sport is going in the wrong direction, but i think it should be displacement limited or do something so people go through the run with some speed!

sorry im going to have to take xeven's side on this one. not on the knowledge part but seriously elitist, you need to stop talking shit for no reason. he didnt say anything to you. if hes mistaken then correct him. dont be a fucktard with an attitude. your name might be elitist but you sure dont come off as elite.

Well good you two can hold hands and man-cuddle.

Elitest you must of missed the part where I said the rolls could probally be reversed. But then again you see people swapping SRs so they can be drag killers right? wrong. And about the SR being a bit underpowered, I was speaking from his point of view. All he'd have to do is turbo the KA and put 230hpish to the wheels for around $3k, whereas the swap will run him more money and and less power, now correct me on that if I'm wrong since you know everything

ok Nissan Elitist KA makes more torque and power, slap a T28 on it and run it at the same PSI as a SR, the KA will (and has) make more power.


OH MY GOD NOOOO HERE COMES THE HARDCORE L33t bURnZ0rZs quote me and say something sarcastic quote me and say something sarcastic quote me and say something sarcastic quote me and say something sarcastic quote me and say something sarcastic quote me and say something sarcastic quote me and say something sarcastic quote me and say something sarcastic quote me and say something sarcastic quote me and say something sarcastic quote me and say something sarcastic quote me and say something sarcastic quote me and say something sarcastic

see what i mean? i dont know xeven. never talked to him before. im not even backing him up really. you still feel the need to make a smartass remark though. you just need to check your attitude sometimes because talking shit doesnt help anyone. your later post where you actually commented on what he said was way more helpful than just calling him ignorant. you can act as tough as you want on the net and NO ONE WILL CARE.

and my KA evidence just to make sure you don't think i'm saying whats "socially accepted" http://www.import-autoperformance.com/

and in all fairness, just abot any engine can be modded for different purposes, but obviously this guy is just getting started out with the 240 world so why not point the guy in the right direction? Its not about which engine is better or whatever, its about whats going to suit him the best, which I'm -assuming- he's regular joe like the rest of us.

Elitest you must of missed the part where I said the rolls could probally be reversed. But then again you see people swapping SRs so they can be drag killers right? wrong.

ok Nissan Elitist KA makes more torque and power, slap a T28 on it and run it at the same PSI as a SR, the KA will (and has) make more power.


Same PSI does not equate to the same flow.

Apples to Oranges

but seriously FUCK V*'s in D1 and FD its some bull ass shit. i dunno its true they do well. besides rhsy millen i think they are shit though. i saw the Mopar Viper and it was the gayest thing ever. !

That is the most retarded thing ever. the only thing wack about the Mopar Viper is the oversteering suspension setup.


there was a lot of tire smoke through the run but his average real speed through the course was probably 15-20 MPH... just one slow, carefully plotted and steered, over-extended burnout! not drifting!! ugh i dont even know what to think about Gushi in the mustang, havent seen it in person yet, but id rather see him in something else. !

Uhh yeah... because thats whats driftings not supposed to be :gay:


i hate to take the stand of being a purist, saying the sport is going in the wrong direction, but i think it should be displacement limited or do something so people go through the run with some speed!

D1 is limited to "No V8s" and D1 has become one of the less respected sanctioning bodys because of their politics based bullshit rankings. at this moment Millen and Hubinette have competent D1 Cars. why? because they dont just throw parts at the car. they think about what they need to make the car better and the do it. with some speed? all the cars at FD Houston were entering at a good 90-100mph... which is only slightly slower than what I saw at D1 in december.

Same PSI does not equate to the same flow.

Apples to Oranges


yeah flow=hp KA wins.

and how the hell else are you supposed to compare 2 engines to see how they respond to turbo than by fitting them with the same turbo at the same boost. i dont see that as apples to oranges at all its an apple (KA) and an orange(SR) with a T28 on it running 8 PSI, and the apple wins.

of course displacement is not the ONLY factor in making power but its a large part of the battle. oh yeah the KA head flows better too. and no rocker arms.

but after saying all this im still getting an SR because it will be cheaper for me (player price)

speaking of player prices that list you made is a pretty tough one to stick to....40 bucks for a radiator?

this is to the thread starter and i didnt read half of this thread it got stupid. so hey man you can drift or drang anything some engines tend to be better for drag others for drift. you can get the sr and still lay down some good times look at Mynismos SR hes fast as shit. either engine you get will be a good choice they are both good

who would pay more than 40 for an OEM radiator?

like I said man I'm assuming he's just an average person, not someone who can pop a $600 SR20DE out their ass and put all the turbo components to make it run properly. The guy has his answer, just drop the subject. And like I said, I'm still waiting to hear someone say they swapped an SR just so they can go out and run 12's.

oh and RW i dunno im just going off what i saw the Viper do. far less impressive than any of the nissans or hachi's. maybe they had an off day who knows. and yeah the GTO especially is raw as hell, im not sure how many other cars have their steering worked over like they do but it works wonders for them (how they made it so it can turn way farther in and out).

and i dunno theres something lame about how the Viper was starting the drift like 200ft. back from the turn, already just locked in sideways slowly plodding along roasting the tires. i guess thats what the competition drifting is now heading towards though. me personally i would rather see some 180 or hachi start off with grip and speed way up and then brake, throw the car into the turn and work with the throttle and the steering to slide it (which is not really a huge cloud of smoke at all, but they are still sideways as shit). i dunno it just seems like theres more speed and danger in it when you are taking an aggressive line and then BAM you lose traction and start the drift rather than having 1 continuous burnout from the spot you started at. just personal taste i guess. dont get all butt hurt.

like I said man I'm assuming he's just an average person, not someone who can pop a $600 SR20DE out their ass and put all the turbo components to make it run properly.

Seems like "make your own kit" gets said alot when people are going KA though.


And like I said, I'm still waiting to hear someone say they swapped an SR just so they can go out and run 12's.

Thats really all Mynismo seems to do... and he did 12s on the stock turbo IIRC.

who would pay more than 40 for an OEM radiator?

i dunno plz find me one for that cheap i cant find em

Thats really all Mynismo seems to do... and he did 12s on the stock turbo IIRC.


haha yeah the stock GT28RS...:gay:

Seems like "make your own kit" gets said alot when people are going KA though.

Yea true about the KA kits, but i put the link up though for the website just incase the thread starter got interested. And about mynismo, shit, he's in a league of his own

I just reminded myself of something so very simple, since when did the engine by itself determine if its drag/drift worthy? What about all the other factors? like suspension, weight reduc. (like miynismo is planning) and etc? its more than just the engine thats makes a car what its good at. duh, lol

im not sure how many other cars have their steering worked over like they do but it works wonders for them (how they made it so it can turn way farther in and out).

All the 240s have Tie Rod Spacers, The Hachis Change Racks and Cut Teeth, The Apex RX-7 Cut new Teeth, and the GTO cut new teeth.

and i dunno theres something lame about how the Viper was starting the drift like 200ft. back from the turn, already just locked in sideways slowly plodding along roasting the tires. i guess thats what the competition drifting is now heading towards though. me personally i would rather see some 180 or hachi start off with grip and speed way up and then brake, throw the car into the turn and work with the throttle and the steering to slide it (which is not really a huge cloud of smoke at all, but they are still sideways as shit). i dunno it just seems like theres more speed and danger in it when you are taking an aggressive line and then BAM you lose traction and start the drift rather than having 1 continuous burnout from the spot you started at. just personal taste i guess. dont get all butt hurt.[/QUOTE]

The Viper was using weight Transfer in and Power Out more when I saw it. it was throwing itself in 50ft back and just idling around the corner, hence the oversteer comment. (no smoke on entry) None of the US drivers take an Agressive line. even the Hachis. its all about race line in the US with no points for showmanship.

i swapped the sr just so i could go out and run 12's

yeah flow=hp KA wins.


Really ... so riddle me this.

How much airflow is used by a 2.2L SR engine at 11,500 RPM given a PR of 3.5?

Figure that out an you have some idea of what an SR has done for years.


and how the hell else are you supposed to compare 2 engines to see how they respond to turbo than by fitting them with the same turbo at the same boost. i dont see that as apples to oranges at all its an apple (KA) and an orange(SR) with a T28 on it running 8 PSI, and the apple wins.


Are you trying to say it's equal to rate a 8.2L Mopar engine pushing 14 PSI to a KA24DET pushing 14 PSI?

So just because the engine produces more power at a lower manifold pressure, although the boosted air temps remain the same and the flow limitations of the turbo are still the same?



of course displacement is not the ONLY factor in making power but its a large part of the battle. oh yeah the KA head flows better too. and no rocker arms.


You seem pretty sold on that notion.

I would like to see proof of your claim that the SR20DET head flows less than the KA24DE head.

Just FYI the lash pads on the KA limit the effective cam lift and size you can run. The camshaft physically strikes the head casting.

I guess those ol' evil rockers much hate running 304 duration racing cams with about 13mm of lift!

Rocker arms afford the SR to run a higher angle of attack and narrower valve angles. It is a superior design in terms of head geometry. You might wanna read up on the SAE papers writen by the designers of the SR engine.

i swapped the sr just so i could go out and run 12's

show me your proof, lol jk. nice avatar pic there bud

haha yeah the stock GT28RS...:gay:

Seeing as how hes had the GT28RS since the dawn of Time :uhoh: he did a 12.8 I remember because he was crazy enough to do it on the stock injectors. I belive hes high 11s low 12s now

show me your proof, lol jk. nice avatar pic there bud
i was being sarcastic and u just noticed the av?

this place is bust for 2 40 am
i cant sleep slept for 3 hours woke up and now i cant sleep
at least i have porn back in 5

i swapped the sr just so i could go out and run 12's
Glad you said it, you beat me to it!! LOL

Are you trying to say it's equal to rate a 8.2L Mopar engine pushing 14 PSI to a KA24DET pushing 14 PSI?




yeah ok V-10 vs I-4 great comparison. i was comparing 4 cyl. to 4 cyl.!

i swapped the sr20 to go run 12s, but its just not enough. i wanna swap an rb to go run 9s!

You boost a V10 at 10PSI, the KA at 10 PSI and the SR at 10 PSI with the same turbo, the V10 will make more power, the KA second and the SR third. Wait a minute! THAT'S THE FUCKING POINT! The KA is bigger then the SR so it makes more power at same PSI then the SR, the V10 will make the most power because it's like 8 liters or whatever. The SR will make the least power because it's only a 2 liter engine. So go ahead and chop up my post so you can make random gay remarks, but you still know I'm right.

I note how you respond to nothing else.

Thanks for the Summary Cheif. What NissanElietist is argueing is that Displacement is not a sure bet to judge HP? what if the Viper Had Penny sized ports? Oh heres a good Example what about a 350 SB making 190HP? there are many other factors that come in to play and your acting like just because the KA has .4 of a liter on the SR its the end all shit in drag racing. - which is to this date not so.



Also, NissanFanatic has argued this same point. (not bashing NF - he knows his shit) and as I recall there was no arguement afterwards.

i was being sarcastic and u just noticed the av?

Yea I was being sarcastic too, and I said nice avatard cuz it related to drifting, not to drag racing. So ina way I was acknoledging (sp) your sarcasticness

And in response to the whole displacement isn't everything arguement. I think a good part of us already know that, hell, most of us can go out right now and fuck up a couple of Camaro's and Mustang's, but the guy wanted to know about KAs and SRs. Being that they're both L4's, the KA SHOULD make more power, but seing as it isn't factory turbocharged the SR naturally is stronger. But then if you add a turbo onto the KA it makes more power and blah blah blah blah. I just think that when it comes down to inline 4's, displacement and/or turbo definitely means alot. Its like adding a stroker kit to a SR, pow, more power. But then again it's all in the set-up. For example Vtec 1.8T would beat a NA 2.0 and so on. So yea, in conclusion I understand the displacement ain't everything arguement, but there's just too many tuning varibales to argue about which engine is better, they'll both get the job done...now excuse me, its 1pm and I'm still susposed to be asleep..

I note how you respond to nothing else.


ok here goes.

1. ok how much would a 2.4 KA or 2.5 or .6 maybe if you bored it make if it revved that high at that boost? MORE!!! just because it hasnt been done yet doesnt mean it ever will, i kinda doubt 11.5k revs but im sure it could go over 10k. over 10k is all it would need to catch up to the SR.. Serious tuning of the KA has really only just begun. Give it some time to catch up. Bottom line its already a serious competitor with rather minimal development compared to the SR (i think theres only like 1 intake mani. in productin , 1 kit for valve springs + retainers.) As it gets more and more attention we will see the HP climb higher and higher. And also, even if it cant get much over 10k revs, and falls a little short of the SR's HP, the torque will OWN. I have no doubt the KA will hit higher numbers than the SR someday.

2. ok already took care of that mopar nonsense

3. i dunno havent read SAE papers, got a link to any in english? and im honestly not sure i have gone through a lot of info in my time and could be misremembering. but wouldnt it naturally flow more because its designed for a 2.4 instead of 2.0? :dunno:

I have no doubt the KA will hit higher numbers than the SR someday.
Good luck with that. The stock crank will fail at 400HP, so, if you replace the entire bottom end, top end, add a turbo, and everything else that you would need, yeah, you may SOME day beat the SR, and you will have spent about $20,000 doing it. Have fun.
