Garrett Gt3071

[GTST-25]

Thanks for the info mafia .. do the garrett gt3071 turb need new lines too ?? i have a stainless manifold... but i will need to get a new one for the external wastegate if i go down this path..

thats exactly right - GCG highflow is the most cheapest upgrade ($2k) and it bolts straight back on, no adjustment to oil or water lines.

2530, you'll be spending $300 on oil and water lines, and lots of time and stuffing around... I've been there and done that, pain in the ass.

If I could do it again, I'd get a high flow. But, I can't do it again..

unless the kit specifically says that the turbo will use all standard RB25 oil and water lines then yes.

ALL non RN25 turbos need new water and oil lines, except for the kits the specify that they will use the existing factor ones - which are rare as f**k.

if a kit supplies all lines , like a gtrs does that make things much easier ? or is primarily a labour thing

[The Mafia]

yeah I guess so, but that would be a pretty expensive kit wouldn't it?

i thought i would quickly check with yall first...

i have a 33 with ems cooler exhaust new turbo manifold etc..

and want to upgrade my turbo... i have decided on a Garrett gt3071 with .63 exhaust and with an internal wastegate....

does this all sound like a good setup ?

Cheers thanks for any feedback

I know a couple of people who have fitted these 3071r .63's to SR20DETS and they suffer from really bad boost creep. One of them is having the internal wastegate modified (enlarged) to try to alleviate the problem.

hey guys they have a T04E on ebay ... currently $360.. would this be any good ? is it too big ??

Cheers

surely you have learnt something in the last 2 pages of advice and previous topics in the forced induction section.

cheap turbo's are cheap for a reason

ebay turbo's are a no no

mystery (unknown spec) old school t04 combos are lag monsters usually

what do you call a laggy turbo?

one that comes on at 3000?

one that comes on at 3500?

one that comes on at 4000?

one that comes on at 4500?

one that comes on at 5000?

hehe thanks paul i know you get what you pay for !

so a 2530 hks would be a good upgrade on mid to high boost ?? compared to the 3071 ?

can anyone recommend a turbo for my rb20 that can atleast make 260KW ATW without dying off 2 bad at high revs and can still achieve good response. Would a gcg hiflow rb25 turbo do this?

[grim32]

Im waiting for my 3071 now, should have it in the next week or so, as soon as it turns up its going straight on.

The GT-RS kit, for what it's worth, was a pretty easy thing to install.

Turbo bolts up to the existing manifold and exhaust no probs.

New oil and water lines need to be used (come with the kit) and are also pretty easy, with the exception of the water line at the back of the engine block which is a b*tch to get to.

It's a solid day's work, but will net you 230-260rwkw on an RB25.

Worth considering for what you say your goals are. I imagine they would be pretty responsive on an RB20, as plenty of the SR20 guys use them aswell.

The GCG Hiflows (RB25) all seem to be getting similar power figures.

I have seen a GT-RS kits do 300rwkw....

Its also documented on the first volume of street ignightion dvd...

A guy with a R33 Series 1 with all the supporting mods reach's 302rwkw's
