Would love to see if the GTX2867 has boost creep issues like the 2871R.


Aaaargh, and I was contemplating GT2871R vs saving much longer and springing for a T3 GT3071R.

I still think stock will be the manifold of choice as it uses the same turbine housing and a similar wheel. In the case of these little turbos, heat retention is king, and what makes them light so fast. Tubular manifolds won't increase response at all especially on a non divided housing.

In regard to to creep issues, I still think those issues will be there, as (again) you're using the same turbine housing with the setup.

Truthfully, this turbo is shaping up to be the new turbo of choice for those wanting to make 425-450 whp in their 240's at the limits of pump gas.

My father's car is a GT2876 84 On a full-race bottom mount T-25 flange
its dressed with pistons rods cams and a D-jetro.
He is happy with it at 13psi the lowest boost setting (probably around 300 horsepower) but as we all know that turbo can do much more. I am interested now in turning it up (twist the knob on a dyno) and finding out where the compressor taps. Something else to compare with? I am also curious about the creep, or lack thereof.
Its just hard to get him to turn up the boost. "but why? its already faster than anything I've found...."

I don't have much 2876 experience, but I can easily see 18-20 psi being well within pump gas limits.

In the grand scheme, it will all creep to a degree...that quarter sized hole, and a simple diaphram as are reliable as Lindsay Lohan not drinking for the evening.

As long as the fuel is there, I'd say put boost controller on her, and make him shit his pants
