By looking at those number looks like the .86 would be a better match for the KA I'll see if I can get my hands on a .86 turbine housing as well & give both a try.

If I remember correctly, the .84 T25 flows similar to the .63 T3??

If that's the case, yeah, a T25 would be an option....although I would personally opt for the 0.63 T3 housing option.

My KA has seen mostly .63 a/r t3's or close and that seems to be favorable.

I know its 2 extra cyl but i had a 3076r .63AR on my bone stock rb25det and it responded very well, made about 14 psi at around 3100 and 22 psi at 3700-4000rpm. until i got my nt05's 2nd and 3rd gear would roast my 595 ss

Has anyone used T25 Plus housing from atp turbo for there Gt2871R or Gtx?

Its a T25 flange but flows like a T3. Is it worth the upgrade for $300 bucks when your shooting for 380whp give or take

That quote is a marketing ploy,
Flows like a t3 part. And the standard gt2871r should make 380hp easy most people have problems making 400 though.

The answer to the 1st question is yes.

Can anyone measure how much room is left behind the sr20 head? My waste gate is behind the manifold. Im trying to figure out if it will work. Im also using the top port for the electronic boost controller.

You should be good. I havent measured, but that looks like it will fit, it will be super close, but should be ok.

Use a 90° etc. or banjo fitting to make the return back towards the bay a lil easier on the hoses, maybe?

you could probably use a tape measure and measure the distance from the bolt hole for the engine mount on the crossmember, to the firewall. And then measure from the stud on the actual engine mount, the one currently on your engine, and see where youre at

AEM EMS V1 with 3.5 bar map. The only downfall of the V1 is that it cant quite control my VTC so that might be a reason to upgrade at some point as id like to have it and got my cams made specifically to keep it.

Is there a graph some where that I missed or something. That torque looks like it was sacrificed to gain hp. I want to see the birth certificate....in mean graph!

I'm pretty happy with that torque level given the motor is stock internally. We had plenty of room to play but this feels and looks safe based on logs. I'm traveling but i'll upload the graph when I get back home next week.

You should be happy, you paid for it!

My comment was on why so many people were fondling the satchel of someone posting numbers with the lack of proof.

So I didn't miss that graph?!

I still believe in the old zilvia, where if you mumbled lefty loosey right tighty, you got ethered!!

Will the 2867 get me there or should i go for the 3071 also this is my purely drift car so response is much needed


You do not need bigger cams for a measly 350hp. Nor do you need a twin scroll or a 3071.
A 16g turbo in a T2 bolt on housing is all you need for that.
