ive searched this and came up empty. i know the majority of you guys dont even drag but for those of u who might have ran your cars at drag strips what kind of times did you get and what was your setup?

how fast should a stock sr20det be in a 91 240sx?

dekand

14's

ANVIL

mid? high? low? is running high 12s a hard goal

-HyJynX-

Low 15s stock S13 SR20, high to mid 14s with some mods and a little more boost

NightXCZ77

Maybe with NOS...KA's don't hit 14's easily being NA.

tegg_gsr

mid to low 14's

sr20dreams

yes from what i know it kinda is.. i have two friends who have there s13's in the 12s one of them is running 12.2 and the other just ran a 12.8 both cars at 110 mph trap speed. both were useing slicks... it is a pretty hard goal to reach but if you do things right you can get 12s, and that is what i am after as well is hitting those 12s but i got to get the sr20 first.

dekand

read before you post night, he was asking about stock sr20s...

ANVIL

after reading other threads im leaning more towards doing an rb25 swap, not too much more for so much power and potential. a lot easier to hit 12s or better with that motor

phantomsi

the probelm is that finding parts are a bit harder with the rb also its gonna be a bit more costly from what i have found out. but i maybe wrong.

tegg_gsr

wouldnt it be easier to turbo the ka for drag? because i thought that the sr was mainly for drifting

-HyJynX-

Every engine is good for everything, but the RB and KA put out a little more torque thus helping out for the drag strip

Nismo241

The KA is better because of displacement over the SR, the RB25 would be my choice, just because the inline 6 is a better design than the I4.

We have a couple of customers running SR20 swaps at the drags.

1993 240SX HB Redtop SR20DET 3" downpipe and exhaust, SSautochrome mani, and 10 PSI resulted in a 13.6 on BFG drag radials.

1989 240SX Coupe Redtop SR20DET 3" downpipe and exhaust, resulted in a 14.0 on stock boost with some good street tires.

Both of these swaps were simply pulled from the clips and dropped in, stock piping and SMIC's with BOV's added. The biggest thing I see that keeps the SR20 from going faster is the gearing in the tranny, it's tall for drag racing.

i ran 13.2 with my sr.
3' downpipe
3'exhaust
test pipe
greeddy intercooler
hks cams
and stock boost.
My friend who has a bone stock sr20det in his 240 ran 14.1
so hyjynx dont say that a stock sr runs 15's because that is not the case. Maybe if the engine was running bad you'd see 15's but it should be better than that
