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?
if it does im gonna buy one.

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 :D

thanks heaps skylineUSA. i have another question which puzzles me.
when they say rear wheel hp what is the conversion to what power it makes at the engine to the rear wheels? example, 280 hp at the rear wheels and what is it at the engine?

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!

i dont understand..shouldnt it be more power at the flywheel? oops i typed it wrong lol..was supposto be 280rwhp not 200. can u tell me that one instead mate?

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

ofcourse it dosent but im hoping to get that if i do mods..but im contemplating. just wanted to know the conversion and what mods do u think i shoulf do if i decide to get that power output?

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.

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.
