1. s13 sr20det or s14 sr20det either one will run high 13's all day long. hp does vary but is 205 ~ 250 either way stock
2. Kwanza - you're absolutly wrong.
a stock 240sx with a KA24de runs high 15's if it's a 5 speed.
a stock SR with FMIC and boost controller runs mid 13's
3. 3sgte is an underrated engine. That thing can haul @ss. CT26 is a good turbo, but of course it isn't gonna make 400rwhp.

1. ok, the 250hp s15 motor swaps are rare, so lets go with the 205-220hp ratings. an s13 with 220hp would not at all hit high 13's all day long, not with out a lot of weight reduction. if 220hp was enough to make a ~2700lb 240sx run high 13's every time, then so should a stock WRX which has about the same HP, with more torque, and comparatively unlimited traction with roughly 300lbs more. you will never see a bone stock WRX run high 13's consistantly
2.i have driven and riden in a s14 with a stock s14 sr20det in it. all it had was intake, it still had the stock 240sx exhaust
the car was not at all fast. it was right at the power level that 240sx's should have had from the factory. this observation seems fairly in tune with Kwanza's opinion
my car was faster when racing him, and that was when i was bone stock and didnt know how to drive my car worth ****. if i had to guess, he would barely hit high 14's, and he was a pretty good driver.
3. he now has a FMIC, down pipe, 3.25 inch exhaust, and a MBC set at 10psi. still only a low 14 second car. not mid 13's
now my car runs consistant 13's, and thats with me being nice to the tranny.
who here has actually gone to a track and driven a car down the 1/4 mile?
the most important part of drag racing is the hole shot, the 60ft, basically, the launch.
the faster the 60ft time, the faster the 1/4 mile time, i think that for every .1 second faster 60ft, its a .2 second faster 1/4 mile time.
i have seen plenty of turbo FWD cars at the track, and they get 2.5+ second 60ft times on street tires when they have the power to get something like a 2.1 maybe faster if they had traction(slicks). take the same car, if on one run it got a 2.5 60ft and the next run was a 2.0 60ft, the second run would be 1 second faster.
its for that reason, that ANY high power FWD car will require professional driving to hit the times its capable of with out the aid of slicks.
and before anyone asks, i have driven an 04 SRT4 and a 93 prelude VTEC boosting 8psi
all high power turbo FWD car, while very different from a 3s swapped celica in many aspects, when it comes down to the launch, they all do the same thing. SRT4 had the factory LSD and it still roasted the tires. the prelude gets traction in 3rd gear.
that was with me trying to get off the line as fast as possible, not getting rolling then rolling into the throttle, in which case, both those cars would still roast the tires in 1st. i will admit, i am not a good driver that can just hop into any car and make it run its best. i can only handle my car, and some RWD cars(datsun Z's with the turbo 1982 engine, and v8 mustangs)
take a 3s powered FF celica, and try to get off the line as fast as possible. thats when you will realize that the car has traction problems. you want a little bit of controlled wheelspin, too much wheel spin, you arent going anywhere, no wheelspin at all means the car is probably bogging.
