Gt3071r Or Gt3271r? Rb20det

[GTS4onP]

I'm looking at buying either of these turbos (can get garrett turbos cheap new)

im also going to be doing top mount manifold, wastegate, front mount and bov at the same time. and will most likely upgrade fuel pump, injectors and ecu in teh future

which of these will be better for my application?

how much rwkw?

when will they come on boost and be at full boost?

Cheers

PS. i know your probly all sick of 'which turbos shoul i buy threads' but couldnt find which of these would be better fr my car

what injectors do u have on right now? alot of people here will flame u and say that the gt32 is to big and even the 30 but it depends wot u want it for? what are u after?

[Justa32]

if your looking for quick fast power, theres a guy in perth whos got 400rwhp on 26psi with a gt3040 internaly stock... if you dont have injectors, fuel pump or ecu its probably a good idea to upgrade those 1st..

On a street car the 3071 is as big as you would really want to go.

[GTS4onP]

oh ok

once im finished im wanting about 230rwkw-ish, give or take a bit. just going to be a street car though

ive only got standard injectors at the moment. the motor is stock apart from apexi poddy, catch can and 3" exhaust

well b4 u get a turbo it would b a good idea to get sum injectors and fuel pump and a computer... u still have sumthing to gain out of the turbo in there at the moment... a gt3071 or a 3076 is a nice upgrade for an rb20

[GTS4onP]

ok sweet. what size injectors and fuel pump would you reccommend? and computer? i dont want to spend to much money, but im not going to be stingy and buy crap quality

[Justa32]

i dont no where ur from but u could get a piggy back computer from a local tuner.. or just get a power fc, injectors and fuel pump is completely up2 u

[GTS4onP]

whats the difference between 3071 and 3076? dont really understand what different a/r ratios and shit mean and how they affect how soon boost comes on, peak power etc

I would personally go GT3071r IW(internal wastegate), and use a stock rb25 manifold. The whole hot side will look fairly stock, and be reliable. You should be able to see about 270rwkw @ 16psi without overstressing things. You will need RB26 injectors, gtr fuel pump, and some engine management.

This is the only one I know of and it's bush bearing .

ok sweet as, the gt3071r seems to be the way to go then. will rb26 injectors bolt straight into the rb20 rail?

[robots]

yes rb26 inj. bolt straight on.

[RaZ_TuRbO]

they fit straight in yes.. but you need to die grind some of the plastic tabs, and you have to wire in a dropping resistor if you have a remap/ stock ecu.

[Adriano]

I would make sure you get one with a genuine garrett ex housing. I would run a .63. You will need a custom dump pipe, and a spacer between the exhaust manifold and the turbo.

ok mint. im going to get a top mount manifold 4 some bling factor lol, so guessing ill need new oil and water lines. and 2 change the intercooler piping. wouldi need the spacer with the top mount?
