^^^^^

the only reason it offers a lot of torque is because it is still prob using the standard exhaust housing which would be bored out

in my honest opinion i think you are basically choking the turbo with this housing,

whats the point of puttting bigger internals in to a standard rb25 turbo and run the standard exhaust housing???

i use to run a proper gt30 (.7 compressor housing) with a rb25 exhaust housing and it wouldnt pull more than 260rwkw even on a forged motor

as soon as i went to a .82 exhaust housing i made 300+rwkw

I was going to say that if it was a true GT3071R external gate with the correct exhaust wheel it would make around the 270 mark @ 19psi (even with the 0.64 rear) but not if it's just a high flowed compressor side using the 71mm compressor wheel.

hahaha yeah 10 years after leaving i found my self living on forest ave

yea like i said ill b happy with 250 to 260 man, if not ill push it to 25psi on e85 and go for 300 haha, hey steve have u fixed ur car yet? as in the bearing?

i don't know about power gains on e85 but i have seen better torque curves but fuel efficiency goes out the window!

    • Yes, it's similar length. 
    • Is the CD009 similar length from bell to shifter?    car will just be for the street with the odd track day. It’s RB30det, and weighs about 1000kg
    • The r34 gearbox is like $3400/3700 landed from Japan sometime last year.   Contact jessestreeter.com for info and quotes. From memory the navara gearbox needs input shaft machined down as I looked into a while back and there's a thread somewhere here from 2018-2021 about it. Depends on what your doing with the car maybe worth the dollars to go cd009 or a 8hp50/70.
    • VCAM doesn't really increase peak power, it just widens the powerband. So if you were giving up power with adjustable cam gears to get better low-end response yes in theory it "increases power" but otherwise not really. Stroker kit might put you in a more efficient region of the compressor map which will get you more power but at say 7000 rpm I'm not sure that much will change. The original HKS GT2530, -5s, and GTX2860R gen 2 are all roughly the same kind of turbo. If you want 600 horsepower those are the turbos you need. So 500 whp. Just expect to spend some quality time trying to figure out intake/exhaust piping. The "twin turbo" pipe is an obvious place to start. Make sure the actuator preload and all of that fun boring stuff is set up correctly. Throw a VCAM step 2 at it if you want good response, 2.8L stroker too. If you're not actually wedded to 500 whp all the time you can barely get there with -7s or Nismo R3 turbos, you just have to run E85 or race gas and run them hard:
