Gt3071r Query

[jaychen]

hey guys, i was looking at getting a GT3071R with a 0.64 rear housing on a T25/T28 flange. was wondering if this would push to much boost for my stock internals. i currently only have 255L fuel pump , 3" turbo back exhaust, FMIC. i would obviously be getting a ECU remap straight after and have already got a boost EBC. ANY HELP PLEASE ? my goal at the moment is 200rwkw+ but am looking to go further in the future and what a turbo to support this statement!

Theres heaps on here about how much the stock internals take, but I think anything much more over that your usually relying on the motors past history and chance etc.

I think the turbos a good choice, im actually looking at getting one myself - good tradeoff between response and power it seems

Biggest factor is the tune.But then again it can blow up anytime.

No the biggest factor is it won't bolt to your exhaust manifold , T25/28 flanged exhaust housings are too small at the inlet for 6 leg exhaust manifolds . You really need someting with a T3 flanged exhaust housing .

Surprised it took that long for someone to point that out...even the dump pipe won't fit...and if you are chasing only 200rwkw or so then you are looking at the wrong turbo...

[jaychen]

well then what turbo should i be looking at guys? help me , you guys know your shit about rb's!

Same turbo, just get diff exh. housing

[BHDave]

same turbo with different exhaust housing is 280rwkw capable though.

for 200 ideally get yourself a hks 2510 or 2530, pricey and getting old though if second hand. The problem you have is that all of the small frame garrett turbos are t2 flanged, the smallest t3 flanged one is the 3071.

You could get your stock turbo highflowed, but even they are generally optimised for power around the 250rwkw mark so you have the response trade off.

Or you could talk to a turbo shop about getting a t28 cored turbo fitted to a modified stock exhaust housing. I would suggest a gt2860rs if you are going to be happy with low 200's, 2871 if you want a bit more.

T3/T4 hybrid

run any turbo that you desire. just dont push the standard internals past 270rwk odd or so.

and make sure your tune is perfect.
