Garret 3040 On An Rb30

[R31Nismoid]

A 3040 is too big, they all carry the 550-600hp region.

3071 is closer to what you want, and would be on very early.

yeah 3071 looks better, thanks titan and ash.

surprisingly hard to find dyno graphs for 3071 (although they are on here with patience), the ratio of expectations to actual results is about 90%/10%

can't find one for $300 tho

[TiTAN]

you may be able to find one second hand but you probably wont find one for $300.

hey duncan.

sorry to hijack your thread

do you by chance have a picture of your setup? and a dyno graph?

im thinking about running a t04e to get me out of trouble till christmas time and was wondering if it was really that good of an idea or not.

cheers john.

[Duncan]

sure do...check out what santa brought me last xmas

would that be at the wheels?

what psi do you think would be required to achieve that?

on a standard rebuilt rb30 would that power be safe with water meth injection and 7500 rpm limit?

sorry to ask these questions on your thread duncan...

thats at the crank, which would be around 450-500rwhp. would probably need well over 20psi with a fairly standard head. with water meth a stock block should hold up alright, all comes down to the tune

[R31Nismoid]

On juice (sunoco 104) i made 370rwkw @ 24psi on a RB25

270-280rwkw on 17psi... So given say 20psi on a 3ltr with a tidyied up head etc - ~310-330rwkw i would imagine is somewhere around the ballpark.

E85 surely would see you 350rwkw if not more.

They flow a bit more than 3076's and most 3076's with meth/20psi (on 2.5ltrs) see around 300rwkw give/take.

Duncan have you considered having someone such as hypergear redo one of your china turbos?

Surely he can redo it to a similar spec (achieve similar results) and his CHRA's seem to have reasonable rep for reliability.

I am not recommending this, I would rather hear you got off your china high and bought a real turbo, but just wondering if you have considered the option.

[Duncan]

hahaha not happening (or at least I am a slow learner). I don;t beleive there is anything fundamentally wrong with every product that comes from a whole country.

but yes, they are modifiying the turbo this time to deal with the weakness (thrust washer)...will see if it makes a difference.

lets remember my goals.....250awkw from an rb30 with heaps of low end torque.

[GTScotT]

Lol good to hear.

Please update once your on track with it.
