Turbo upgrade

[band1t85]

Hey jus wondering if anyone knows of a turbo upgrade for rb25det, that does notrequire fuel mods or any tuning or any thing serious just a little somethingto get me into the low 13second range. Any help would be great thanks.

Any major power upgrade will require tuning. That being said, I'm pretty sure suspension and drag radials with an S-chassis and an RB25 should get you in to the low 13's.

4.36 final and some slicks...boost at 14psi and one hell of a launch.

its already got tein h/a's on it and some 265 nitto nt555's.... it still has the stock turbo on it and i was under the impresion that you were not supposed to boost that over ten pounds (currently at around 7-8 psi) please correct me if i am wrong. otherwise i would be looking at a little something something more turbo wise.
thanks

Tein h/a's are not drag suspension. Stock stuff would probably work better. Also, if you do indeed have nt555's and not nt555R's, those are garbage tires for drag racing.

With the stock ecu and nothing to tune with, run the stock turbo at 10psi. Anymore and you'll gain little or no power. More than 14'ish will likely keep the life of the stock turbo very short. You cannot put a bigger turbo on you car with out tuning. Get that idea out of your head. I'd look at drag radials, swap on the stock suspension (at least in the rear) before you go to the track, and practice practice practice.

My rb came with gt32 on a stock tune running 7lbs of boost. At the time there was no a/f meter but the car ran decent and no knock. One of first things I did where get an ecu and a/f meter but the stock tune did allow it to operate with the somewhat larger turbo on low boost...granted more more power/reliability was pulled out with a proper tune...even at same boost levels. Ran mid 13's on stiff suspension and crappy kumho's with stock tune.

Mine ran 13.2@108 stock, no LSD, all season tires on 12lbs. If low 13s is what u are after, try running what u got now

yea that would be nice if i could run that, i guess ill try cranking up the boost a little although i am a little hesitant to do so as i have heard people having bad luck with thier stock turbos past 10 psi

thanks for the input
