horsepower: from turbo back 3 inch on rb25det?

hey once again
just wanna know how much hp would you make at the wheels from a 3inch stainless turbo back exhaust, on a r33 gtst s2?
also has a pod filter with a heat shield... and does a z32 airflow meter help?

For the money, I would go N2O A nice little 50 shot or 75.

To answer your question, 10-15rwhp. Whlie a 50 shot would be close to 100hp gain

Re: horsepower: from turbo back 3 inch on rb25det?

15% drive line loss for a manual (roughly), so if your car is around 200rwhp, at the crank that would be 230hp.

Like I mentioned, I would not waste money on a z32 MAF. Apexi air filters are a good place to start Don't buy HKS air filters, they are crap!

Your car does not have 280 at the wheels, unless its been moded with a new turbo?

Re: horsepower: from turbo back 3 inch on rb25det?

The downunder sites mods GTSTs all the time. I would go and do some research, to find out what you need. My GTR woth R34 GTR turbos, custom exhaust, boost controller pushing a little over a bar is only putting out 270 at the wheels. For you car to make that power, your going to need a turbo upgrade, I would think.

Re: horsepower: from turbo back 3 inch on rb25det?

An R33 in Australia with 10psi and a 3" exhaust with a good hi-flow fuel pump and a stock ECU should be putting out around 170rwKw's or about 230rwHp. Flywheel figure would be around 240Kw(320Hp) as Australian dynos are calibrated for 30% drivetrain loss.

The Z32 AFM is a waste of time unless your factory AFM is holding you back... Z32 does cause idle problems though as it looses its tuning resolution. Keep the stock AFM until your making more than 240KW's@wheels.
