A standard, GT-series GT3071r? A g25-550 would absolute shit on it everywhere. Your whole powerband would just move up and to the left.

Garret, for years, have had an outdated turbine wheel. Shoot, the old outgoing wheels were coming along on 40+ years old and all they did was address the compressor wheel.

To be fair, a more efficient compressor wheel does mean the turbine has to do less work, so it's kind of a "rising tide raises all boats" kinda deal. Your point is definitely valid though, which is why EFR's just shit on everything when they were introduced. It's nice to see other manufacturers stepping up. The new Xona rotor stuff looks pretty cool too. Hard to find guys outside of drag racing using them though.

Found this on NRR. Told you so to all those people that think they need the big turbine housing.

It would be interesting to see it rev out more. 7500 isn't really that extreme, however, great power at 4K rpm. Also E85 though. Pump gas would be great to lay overtop to see the difference.

excellent numbers. really making me reconsider the GTX3071 I have for my sr20vet. Might hafta toss that on the sr20det in the missile car and order a new setup for the other engine.

^just sold my old precision, and got a gt3071r for my sr setup..wonder if ill be replacing the turbo with one of these...hmmm

e30gangsta · 09-03-2020, 07:02 PM

I am curious if that motor had cams, or if the vct was engaged at all.

Colorado S14 · 09-03-2020, 09:57 PM

What do you guys think for an extreme response KA24DET set up? I am in Denver, assume a density altitude of 7000 feet, hard on turbos. In the process of rebuilding from a blown engine. Looking for a machine with the ultimate in response and an uncorrected 400whp on 91.

It is hard to tell from the picture if the VTC solenoid is intact. If it was, I would expect it helped decrease the spool. It really does help these motors make peak trq much sooner in the RPM band.

I took a better look, the solenoid is there.

It's impossible to tell spool from a dynapack dyno anyway. They always have parabolic torque curves which don't accurately reflect loading when on the road.

Regardless, this turbo is a phenomenal performer, and doesn't need the .92 housing to reach it's flow potential on a two liter. The G25-660 doesn't seem like it can flow much more with this turbine on the other hand, regardless of housing.

Here's another find, KA24 with a G30-660. I've asked him to post the dyno graph if he has it.

A view of the course at Mid State Airport in Pennsylvania. The car felt like a new animal on my first run, much more responsive than the old GT2871 and the extra power would spin the 315's with ease. The trans 2nd gear ratio (2.077) is shorter than the stock S13 trans (1.902) which ended up having me doing 66mph at my redline of 7400 when i was used to doing 73mph. It sure felt like i was on limiter in a lot of places and I'm figuring with the response and power that i was just reaching 66 that quickly on this course (the clutch and TOB appeared to see a lot of heat : more in later posts).

On my last run, which ended up being a re-run is when all of the fun came to an end, with the engine blowing the #3 rod out of the block..

tuzzio · 09-05-2020, 07:41 AM

I have a LOT of questions about that KA set up. Thats fucking stout, for sure.
Sucks not having E85 conveniently available though. I'd turn my KA up for sure.

Edit: Poorman, can you start providing links to where you're finding this shit? I love forums and I'd definitely like to hear more about that setup

Sheesh, posts like that get me really excited to get my car running. Those numbers are really impressive, interested to know why they stopped at 7500rpm.

Tony at UMS will be tuning mine as well, my car is setup for flex fuel so I'll be able to show an pump gas and ethanol chart on an S13 SR.

You could just have this discussion on NRR where you're pulling all the info from, lol. Most people in this thread are on there as well.

Meh, this forum has a lot more traffic, and these are mostly posts in different people's threads. It's nice to have it all in one location.

EDIT: I'll start a thread in the forced induction section.
