Ok guys

I have a 3L nitto bottom end

26 head with 1mm oversized valves, jun cams, ported

Single fogger nos kit

Greddy plenum

Trust 100mm drag cooler

Going 6870

Should I get the .84 or 1.0 twin scroll rear

Chasing max power but more interested in how laggy the bigger rear housing is

Any advice would be much appreciated

Pt make the numbers, but they seem to be pretty fussy with oil contamination or old motors compared to Garrett stuff . My mates 6466 leaks oil out the core..after 50km..he didnt fit a filter..as he doesnt ever listen..

Another guy i know went through 2 BB 6766's in quick succession, then fitted a filter and had no problem. Wasnt a old motor.either.

Both rb30s. Bad luck..dont know..

Would i buy a pt ..yeh (and have done and will again when 6870 t3 comes out) , would I ever fit one without a filter, nope , thats for sure.

cheers

made 501 @ 20 psi on 98 full boost around 5k.
still gotta do my e85 tune.

Im looking at going to something smaller but wouldnt mind getting some ideas off you's guys. i have looked at going to the smaller rear housing .62 i know ill loose top end but yeah just trying to find something more responsive. Don't get me wrong shes fun to drive on the freeway and rolling starts. I got the whole kit off a friend for cheap and he made 620 @ 25 psi on e85 on a stock 26 but he was getting boost around the 5500 mark. have got this turbo up for sale as im gonna be looking at a 6262 or 6062.

Don't choke such a large turbo up with a peanut sized rear. Want more low end? Go to a smaller turbo and have a decent rear end. Not a compressor that wants to flow a million HP but a rear that wants to flow 500. Compressor limited not turbine limited. It's a much healthier way of doing it.

sweet cheers for that bro.

^^^What he said! You will turn it into a turd mate. Whats your power goal? Pick the right size turbo for your application. If you are going E85 go a size smaller even for killer response!

Like i said i got a good deal on it at the time i was about to rebuild my twins and had everything out of the bay. im looking around the 600-700 mark. if my bottom end goes ill rebuild. next size down is a 6466 or even 6266

    • Checked with amayama and nope, the full S2 manual set is not available anymore. Unsurprising, but still disappointing as the ? on availability gave a glimmer of hope.
    • I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.
    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
