As long as you have the money, you can achieve whatever power you'd like. The GT35R is good for what you're aiming for, you're gonna need head work to get it to spool at a streetable area of your RPM range though.

My advice to you, is be prepared to dump money into your car if you ever pull the trigger on something like this.



...

You're gonna need WAY more than that.

errrr theres quite a few 500whp sw20's out there, a good IC radiator water pump and maybe oil cooler, good engine lid fans and its enough. theres 600-700 whp ones which can cool well too, im not gna be endurance racing with it anyway, i will be using turbo on / off, at least in 500whp map.


nobody has rly answered my question, the one i rly came here for, how much difference does the a/r make at say 5000-7000 rpm? and t3 or t4 inlet?

If you say so man, it will be enough to keep you from overheating but not enough to keep it as efficient as you want it to be, heat soak your IC/rad and you're throwing power away.

As for your a/r question, if you're going for the GT35R, grab a .63 a/r on an undivided T4, it spools faster and flows a little more than a .82 undivided T3.

hmmm was thinking twinscroll for sure,

basically lets say divided t4 0.63 / 0.82 / 1.04 .... keeping the flange variable the same, so either t3 or t4 for all 3, i was just wondering how much difference in topend such a/r jumps would make at a given psi, my guess would be 20whp at least. but wanted to see if any1 had firsthand experience. dont know if its that relevant either, just curious cuz thats how i am lol

tnx for input so far

oh and what other cooling measures would there be then? all i can think of is chargecooler system and cooling ducts all over the car





rev 3 1994 JDM turbo

A friend of mine (former storage unit partner) had a .64 undivided T4 on a GT35R on his SR20, 25psi by 5200rpm I think it was. Prior to that he had a .82 and it had full boost right around 5600rpm.
Power wise, you're right, it's just around a ~20hp difference when going T3 to T4 but staying with the same A/R.

The most noticeable difference between the housings are the spool characteristics, not the power output, that has more to do with the a/r

I can't speak for divided flanges because I haven't dealt with them.

Cooling wise, I'm going to be running water/meth, stupid sized IC/Rad, dual oil coolers and ducting this season, should keep me right around 175-180F comfortably

I could tell from the first post... this is a troll.
