dyno results

[TruJDM]

so as part of my due diligence to Radek and RStuning and to everyone that helped me out in the thread i posted in the spring about turbo set ups I have my dyno results

its a 92 gts-t with the rb20det
3 inch exhaust with test pipe
Nistune
greddy profec B boost controller
walbro 255lph pump
hks mushroom intake
850cc injectors
poncam profiled cams
Tomei cam gears
rb25 turbo with a garret tbo 3 chra all steel wheeled
FMIC

on 15lbs of boost it made 328hp and close to 300ftlbs of torque. This was made with both gears set at 0 degrees, I will be going back soon to make some adjustments and hopefully squeeze some more power


during the build

Any comments or questions welcomed

More rear pics.

Awesome numbers dude! Where did you get the cams?

[Supraclean]

256 poncams? Or higher?

Rear shot


The cams are actually my stock cams. I sent them out to a local machine shop and had them reprofiled to 256 degrees with a 8.5 lift, poncam specs. Only cost me $200 much cheaper then buying Tomei

more RB20 love. The little engine that could.. Solid numbers! It's a shame that the intake plenum and piping is so long.. From what I gather that's whats hindering most of the performance (long intake runners, large plenum), not to mention a restrictive head..

Going to use a more ergonomically designed intake plenum for next year and port my head even more, maybe larger valves in hopes of seeing 380whp up from my current 360...

You can easily run 20psi btw. I run a safe tune @ 18 psi, and 23 psi as my "Hi" setting. Also, if you plan to keep the motor, a water meth kit will do the rb20 wonders..

380 is some serious power. I agree that the Intake set up sucks especially with the over the radiator intercooler set up that I have. I still have to go back to
Dial in my cam gears so we will try pumpin the boost up a bit

Radek did great work on my gtr 414rwhp, conservative tune. nice numbers to see!

Unreal numbers on your RB20 man! Congrats

Off topic but how is it on fuel? :P

Im loving the look of the valve covers and coil cover.
