im interested as well. the stock turbo would prob make too much pressure in the cylinders, thats why the compression ratio is less in the turbo than the n/a

Which "turbo" are you referring to?

I believe the vvti gte head will bolt to the ge block, but I'm not 100% sure. Even if it does, one of the biggest problems is that you'll need to change out the complete wiring harness and ecu, and add in things like an ignitor in order for the gte head to work in a ge (non-turbo) Supra.

The stock twin turbos won't bolt up to the ge head. You're right that the ge pistons have a compression ratio that is too high for forced induction - at the very least, run a super-thick headgasket to compensate - ideally put in gte pistons.

Should be 6, as far as I know...

A T04Z is plenty large for street use.
