Ready for more boost???? Help - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I am driving an sr20det and I was wondering your guy's opinions on if I am ready to run more boost. My current supporting mods Huge front mount intercooler, 3 in exhaust, and walbro fuel pump. I have a aem wideband and run about 11.0-11.3 at wide open throttle and 13.5-14.2 normal driving. My current set up is running about 7 lbs of boost.

Do you think with my current set up the stock sr ecu could keep up with 12 lbs boost all the time?

on a stock turbo? t25?

yea turn that bitch to 14-15 psi. its fine

I put it up to 10 psi today and its working great. I drove it for about 15 min and I could notice a huge diff.

I let the car run for about 3 min after I ran around. I dont have a turbo timer do you think thats long enough so I wont cook the turbo with oil?

your stock turbo sr oil/water cooled meaning you dont have to actually let it cool down BUT its always recommend after a hard drive or just drive normal for a min or so and ull be just fine

yea and also with a ball bearing turbo you dont really need to let it cool down as much as with a ceramic turbo, and only after some hard driving, so i think you'll be fine, but it wont hurt if you do

you will be fine running higher psi on turbo especially if you have the FMIC, you only need to leave the car running after you stop if you have been running the car really hard or redlining it (basically forcing the motor a lot)
then leave it on a bit to cool down, I have an extra turbo timer(greddy brand new) if you do need one.
hope info was usefull

You don't need a turbo timer... It's all marketing. Only time I ever let my car cool down is after I've just done several good passes through my local hangout other than that I figure by the time I've found a parking spot the car should already be cooled down.

Turbo timers are fun, you get "your car's still running" all the time....
