Is it possible to use the BHW exhaust manifold with turbo adapter plate on the ALH to upgrade to a GTB2056? I've read some different info on this.
I have a BHW manifold and the adapter plate from Darkside. Who did your tune with that turbo?If looking to go cheap, not a crapload of BHW manifolds floating around... you can also look for AHU/1Z manifolds as the wastegate turbos bolted to the exhaust manifold like the BHW. I used a 1z manifold i found for a nothing for my gt2256v build.
Why? What do you want to know?Who did your tune with that turbo?
Any of the big guys will write you a good tune for a gt2256v. 26psi sustained on a stock ALH engine, excluding head studs. Turbo would easy make 18psi at 2000rpm pulling a tall 5th gear up a long grade with no problem. So it pulled hills like a stock turbo 18psi tuned car... but then would rip at/above 2500rpm with 26psi to just before red line. Pretty good turbo really. No fussing with odd actuators, actuator conversions, clocking etc. Weld up BHW/1z/AHU manifold adapter and bolt it all together with a braided oil feed and a pushlok hose oil drain.Because it sounds impressive. Curious to hear more about it.
