Is the flywheel on the VQ the factory dual mass one? If it is, it is very heavy, a Jim Wolf one is very light.

Wicked... Thanks for posting this. KAE is lighter than expected and the VQ somewhat heavier.

I agree with the SR tranny idea for VQ/Lucky Dog. I'm wondering if the KA bell housing would match up better?
Assuming the flywheel clears (which I've read that it does with light 'alterations'), the biggest issue I see is the starter recess being several degrees too high on the 4 cylinder bell housings compared to the VQ mounting.

Thought I'd add a bit more info to the already awesome data shared here...

The KAe's 358lbs vs the SRDET's 372lbs was much closer than expected (only 14lbs). I was curious how much did the turbo/exhaust on the SR account for that?

KAe exhaust was missing the bottom collector which is identical to the picture of the weight taken.

So net difference in exhaust setup is about 14.5lbs which means both engine assemblies w/o exhaust are approximately within a pound of each other.

I can add that my L20B truck exhaust, with turbo and waste gate weighed 19 lbs.

So the clear answer is Turbo KA!

I feel the opposite. The clear answer is SR :)

The SR I weighted is a S15 spec R so it has the dual disk clutch which maybe why the weights are so close. It's a heavy bastard!
