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!

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.

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've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.
    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
