FNG here.

I await delivery on a 1987 6.2 L with a TH 400 stock transmission.

I have the intake and exhaust manifold and turbo charger from a 6.5. I am aware there are differences between the heads?

has anyone undertaken the task of turbo charging a 6.2? Is there are preferred method?

Is it as simple as swapping to a 6.5 head set? Which 6.5 head should I use if that is the case?

I am not interested in transmission swaps or swapping in a 6.5. I guess that limits some of my options. I am also not interested in switching in a Cummins.

Thanks,

T

Yes sir, put a Gale Banks Sidewinder on mine, then removed it for Whipple supercharger...worked good, was fairly easy, did not use the stock air box, just ran a K&N off the turbo.

This turbo was designed for the 6.2, no head swapping was necessary

Just as a conclusion 5 years later... I have a Whipple and I will be installing it. I have one on my Hummer H1 and it works well.

there is a mode on pump i think when adding turbo. just from memory im thinking there is a screw you turn like 3/4 turn.
