Well I went to the local drag strip the other night and it turned out to be a good night. Here is the list of my mods.

93 240sx coupe
SR20DET Blacktop
Intake
3" Blitz Downpipe
3" Test pipe
3" Catback
HKS FMIC
Greddy Type S BOV
Greddy/Trust Oil pan
HKS Turbo that came on the motor, so I don't know which kind it is
Greddy Profec B boost controller
Greddy Hot pipe
S15 stock LSD
ACT XTSS Clutch
and Yokohoma AVS ES100's on the rears at 20psi

I was running 12lbs of boost and my speed governor is still in which is causing me to hit it about 40 feet before the end of the strip.

Anyways here is what I ran, and I have such a low trap because of the speed governor hitting and making me coast the rest of the way.

R/T: .775
60': 2.036
330: 5.729
1/8: 8.690
MPH: 84.55
1000: 11.236
1/4: 13.431
MPH: 96.46

I was pretty happy with that. Especially the fact I was hitting my speed governor 40ft before the end of the track which sucked. Anyways, taking a rough guess I'm saying I could easily pull a 13.2 and if I can pull another 1.9 60' like I've done before, possibly even a 13.1 . Who knows, let me know what you all think?? Comments, suggestions welcome.

Running a torsen LSD huh? Nice.

Pretty nice times, just need to get rid of that s.g. Your hitting the s.g. in 4th?

cut the wire that fees the speed signal to the ECU and your SG will be gone!!!

If I knew which wire was for the speed governor, I'd love to do that. I just don't want to mess something up and cut the wrong wire.

jonpowell

look for the SR20DET inpouts and you will be able to figure it out....

I will look into it also for you

jonpowell

Pin 32

Thanks I'll see if I can figure it out.

dont you also have to pull the tranny sensors for 4th and 5th gear?

jonpowell

No, just cut the speed signal to the ECU and it has no clue how fast you are going. This is what I do with the Rb25 installs I do so that there is no speed governer. The SR20 is very very similar in alot of ways.

Jon- I tried to do that with my ka and it used to the check engine light on. I reconnected it back because I wasn't sure if it would make it go into safe mode. But if you always do it, and not have any problems with it, then looks like it's all good.

is it the same with the rb20??? Will my speedometer still work? and What pin is it??? 32?

The signal goes from the Transmission to the instrument cluster and then to the ECU. I raced a SLK 550 on the interstate and not only did I wip his ***, I also hit 150 mph. My SR impressed the hell out of me that day.

Those are sick times man! Do you have any idea what kind of power you are putting to the rear wheels? Ballpark, or dyno?
