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

1.00 minimum.

Bit silly to choose an 1,100 HP turbo then tighten up the rear in the quest for response. Let it breathe!

[eXquiSit]

sweet

just checking

for front housings, any difference between the sp and h?

was looking towards sp

[eXquiSit]

ps. thank you for the advice piggaz!

Air cooled? I think you mean oil cooled.

you'd want to put a a filter on the feed line...they are more fragile than a garrett..

Speaking from experience ?

[jet_r31]

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

Anyone have a 7175/7675 gt42 0.98 t4 divided rear they want to sell or swap for my 1.12 t4 divided rear ?

[eXquiSit]

is there a difference between sp and hp front housings in terms of power production and lag?

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.

^^^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
