I love the 2860rs, the 2871r is good-but-not-great, as with the 3076r. But the 3071r is a flat-out beast. It performs amazing in every car I've personally seen it in and seems to have better response than the 2871r. Still, it isn't as responsive as the disco potato.

The GTX2860rs would be nuts. There are rumors abound and it will likely flow 400hp worth of air with a 60mm compressor. Insane.


I have the 3071r and I am really curious to see real word numbers with the gtx series turbos on a sr20.

I think this thread requires build specs...

IMO....

If stock bottom end then = 2871

If built, I see no reason not to go 3071 to use your built motor.

I guess elevation kills these things. The 60mm turbine is just too small to make a ton of power with. Unless you like running over 30psi boost at sea level. I'm sure the turbo will flow 550whp worth of air in that situation.


have you tried meth/water injection in to the compressor inlet? Its rumored to shift the compressor map to the right for a gain of 10-15%

you could hit 500whp easy with it

Fair enough, but when I go for anything serious it is going to be far more serious than that



Borning? is that like Jason Bourne? or like birthing a child?

I'll give you something better than a 3071 for your soul, but you will have to hand deliver in a box with a bow and ribbon.

Doah!! Gotta love iPhone auto correct!! Gtir t28 is boring now...must get real boost!!

Haven't tried the water meth yet. Still changing things up. I think I'll get the GTX35 and if it is too big I'll go GTX3076r.

But if I had a DET I would go with a T2 based turbo and keep the stock manifold. Unless I was shooting for 400+whp I wouldn't spend all the extra money on a nice tubular mani and bigger turbo.

You know you want to see the results when I drop a 2871r into my T31 turbine housing.,I wonder if i can hit 400whp on a stock DET with only S3 cams ??
