Vt spac L67
I have a 2000 vt spac supercharged v6 with an L67 engine.
I’m trying to find out how I would convert it from automatic to manual. I’ve read a few posts but can’t seem to find the awnsers I’m looking for . I pretty much need to know the whole process

Do I need a supercharged s pac manual gearbox or can it just be a standard gearbox from a vt/vx? I’m planning on putting a new pulley in and running more psi through the supercharger, will I need a better gearbox if I’m going to produce more power from the engine or does that not matter ? how much will it cost me roughly.?

unrelated question but how much psi should run to maintain a healthy engine but producing as much power as possible. The car has an exhaust system. Everything except extractors( high flow cats, 2.5” exhaust and twin muffler tips

Some will dissagree with me but I would look at using a T56 it's a better box than the VT 6 manual.

I'm not 100% but I think you need to get the PCM tuned as I think the PCM is the same in the manual just with different settings. I may be totally wrong if I am you need to change PCM.

Also you need to find the correct flywheel or you nees to get the crank and flywheel balanced.
