240sx/w sr20det vs. RSXtype S turbo.

[Cattalbus]

I have a type S turbo and a 240sx once I get the swap done on the 240 do you think I will be able to win a 1/4 mi race. the RSX puts down about 220 to the ground. good for about 13.2 in the quarter mile. do you think I could take it with sr20 with exhuast 3inch from DP to muffler and FMIC on stock boost?

what sort of times am I looking for at sea level with stock boost?

My 240 is a drag only car so weight reduction is the first mod. if you want to call it a mod.

Let me know what you all think.RSX turbo Vs. 240w/ sr20

[Aries]

the RSX will still beat your 240.

[AZhitman]

I'd need more info on the RSX... Low 13's sounds shady to me.

[Cattalbus]

I have seen 13.8 with a CAI and ECU on falken tires. the car puts down about 170hp on a dyno. but more average drivers could do about 14.1 in the same car.

The RSX I am racing against will have a Greddy turbo kit with a HKS BOv, on 7psi. it has the Emanage system on it. and will have a FMIC by the time I race him. good for about 270 at the crank.

[AZhitman]

I'm confused... Which car runs a 13.2? Which one has 220 to the tires?

RSX? 13's with those two basic mods??? Is that downhill with a tailwind?

[S13240]

RSX will win hands down, not unless you have more mods and up your boost. That's an upgraded turbo kit on an RSX and you're gonna have only the stock turbo at stock boost running him...it's so obvious who's gonna win and who's gonna lose already not unless you're an experienced drag strip racer and take the guy to an unfamiliar drag strip and race him...eventually the guy will just burn his tires if he's very inexperienced at the drag strip and you'll win.

[MainEvent212]

yeah...RSX type S puts down 200hp at the crank stock

a turbo kit should give it like 280 at the crank...making that like 250 at the wheels right?

rsx by 2 cars lol

[240SXer]

The 240 will always be able to win. Just get an LSD, some slicks, strip the interior, run an aftermarket turbo @20psi on race gas. But with the way you mentioned the race it'll be totally unfair, RSX has high compression, SR is a turbo motor. Run the SR at like 14psi or so on the stock turbo and it'll be more of a chalenge. 13.2 with a 220fwhp RSX seems a bit exessive. I just raced a TypeS in my 240 that had exhaust and CAI and I had him till 60. FWD sucks, you all know it. No traction. That's how my heavier car with less power was able to hold so well.

[goldollar]

upgraded turbo at 20 pounds of boost is not an option. A stock sr with front mount, exhaust, and stock boost, is not going to beat a rsx type s with a turbo that runs 13.2, it aint gonna happen. I mean i know this is a 240sx board, but come on its common sense, give respect where due. Rsx are already preety fast out the box. No doubt with those mds its the rsx all the way.

[240SXer]

The only problem is that a 220whp RSX would not run 13.2

[Onizuka]

somebody on these forums posted a few months ago that he was at a drag strip and his friend (or some one he met) had a sentra with a stock SR20DET that ran a 12.9. It had something to do with dissabling the wastegate or something... and that was FWD. It was in one of those "what 1/4 mile times with a stock SR20" threads...

[Ajax]

I think your best bet is the way you're going- chuck all that crap out of your car and that's where you'll get the advantage. Not sure what the RSX weighs but I would think you'd be on more even playing fields at that point, then its all in the launch.

[240SXer]

I saw a dude with an altima with a stock SR20DET at the track run 14.8, FWD.. He said he couldnt get traction. His best 60ft was 2.4.

12.9 is crazy.. Are you familiar with the weight transfer of cars? When you accelerate your car lurches backward. Taking the weight OFF the front tires, and ON the rear tires. FWD cars suck at launching.

[Repo Man]

It had something to do with dissabling the wastegate or something...

Disabled wastegate = expensive/embarrassing day at the track.

[Onizuka]

yeah i know, thats what i thought, but aparently it didnt do any damage, im gonna have to look for the thread so you guys can know what im talking about...

[240SXer]

What does dissabling the wategate do?

[Onizuka]

your turbo will go to the maximum boost posible which should cause your turbo to destroy itself.

I cant find the thread cause im too lazy to look though like 25 threads, if someone else wants to look for it they are welcome.

The best i could fine was a 13.2 on stock everything but FMIC, fuel pump, and race gas in past threads.

[Rockenreno]

a lot of the time it just depends on the driver too, that can make more of a difference than a little more power here or there in a closely matched race...

[240SXer]

Doesen't the turbo push the same amount of air all the time? The wastegate just blows off the excess, right? Or am I wrong?

[Cattalbus]

well the 13.2 may have been a stretch for the turbo RSX lets say 13.5 do you think a 240sx with the SR on stock boost is capable of a time like that. now this is at Houston raceway park we get damn good times at sea level in the winter. My personal best with only a SRI is 14.78 in my RSX. thats like 168fwhp.

[AZhitman]

24 hours later and I'm still confused.

[Meantime]

You'll need more than an FMIC and downpipe to beat the turbo RSX - assuming you are keeping the stock turbo on the SR. 280 versus 220-230 (max) is a pretty big power differential. He would have to launch like a brick for you to have a chance of taking over.

[Cattalbus]

I thought the stock turbo could boost up to 14psi. or should I say was effecient up to 14psi.

[240SXer]

Yeah.. It should push high 200s @14psi with a FMIC. I think that would take the RSX. It's totally unfair to run them at the same boost because the RSX has NA compression. Unless we run both of them at 20psi That way we'd destroy the RSX motor

[240SXer]

I've seen somone run the stock turbo up to 18psi for a few runs. I guess it causes more turbo damage than it give performance past 14psi. I'm sure Stock turbo @18psi would at least push low 300s with intercooler and all that is.

[GatorS14]

Rsx turbo w/ fmic,7psi VS. 240/sr,fmic,gutted interior

if you turn up the boost any from stock and know how to launch you have him!!!!

[240SXer]

Most people dont' realize ow horrid fwd cars launch.. Or maybe I think it's worse than it is. There are a lot more variables than just power.

GatorS14, how did you get your car to go so fast in that picture? I mean the goveornor... This is the best I could do...

[Cattalbus]

ECU flash will take out the governer

[240SXer]

I'm gonna get an SR eventually I don't wanna spend that kinda money on my KA
