Need Help Picking Out A Turbo. Urgent

[robots]

I've been doing some homework yesterday, reading lots of stuff about the gt3071 on SAU. And finally made up my mind.

That a "real" Garrett GT3071R IW is a pretty good turbo for RB25 for lazy(low boost) 240+rwkw.

Is it this one? http://www.turbobygarrett.com/turbobygarre...1R_700382_3.htm

At the same moment I'm also looking to buy a decent turbo for my rb20.

I think gt3071 will be a bit overkill for rb20 in terms of lag. In case you guys can prove me wrong.

1)

I wanted something more responsive from my rb20 and the discopotato was always in my head.

The problem was with the turbine flange, it was always a t25. Until I found a turbine housing with t3 inlet and ford 5 bolt out.

Here is the thing:

You can buy a full turbo assy with the t3 turbine inlet, but I'm a tight ass with my rb20 and I wanted to buy a turbine housing only. Then just get some chinese gt28rs and slap its compressor on the turbine housing.

Then the final part. What size ? I thought A/R 63 will be perfect for the RB20. What do you guys think ?

Also should I get the IW one or go with external wastegate? I have all the parts for the external. Just want to spend less time installing all the bits. And driving the thing sooner. In that case which one is a better go ?

2)

A for the rb25.

Those guys also have a GT3071R (http://www.frsport.com/Garrett-GT3071R-Dual-ball-Bearing-Turbo---Options_p_7839.html).

But they didn't bother specifying the exhaust A/Rs and other options.

Only discription I found is this:

"Turbine housing style available in Standard GT or with T3/T4 Ford Style 5 bolt turbine housing. Compressor housing is T04E frame size with 2.00 outlet. Compressor inlet is available with 2.75 or 4.00 inlet."

Which one of that is the real GT3071R? Or should I just send them the garrett p/n and hope that they can get it for me ?

Thanks in advance!

how much $ do you have

what do you want out of the car

what mods do you currently have

[robots]

I have around 2k for parts for both engines.

I got 444cc inj. Got EMU. Z32 AFM.

And all the supporting mods.

I want some 240+rwkw form the RB25 for street/occasional drift days.

rb20 will be a daily mostly. Just want something over 200rwkw with good response. Nothing mental.

rb25 go the garret 3071..

rb20, the GTRS kit would be an awesome fit

Can anyone post the full garrett part number for the real gt3071r with IW and 2.75'' inlet, not the 4inch one ?

Would really appreciate it. I'm confused with all garrett specs.

have a read though. The real 3071 is a bit of a bitsa the way garrett list it. You basically spec your cart, your compressor housing and your turbine housing separately and get your supplier of choice to assemble it.

The link shows the comp and turbine housing options and part numbers. What it doesn't show is the garrett IW housings which you just have to specify at the point of sale as any turbo specialist should be well aware of them by now.

All that said, i'm still having creep issues with mine, even with the enlarged wastegate, but i really think it's tune related now.

240 is a bit of a low expectation of a 3071 incidentally. i have already made 260rwkw with a heap of timing out of it and half throttle as it just couldn't control boost at all at that stage.

for a 200 rwkw rb20 i'd go no further than a 2530, i'd even go a 2510 if a second hand one pops up.

i think ive got a 3071 turbo that i am selling, what is it worth ? $950 second hand ?
