I'm sure I'm not the only one to think of this...

Z6 block, and 88-91 Si non-vtec head = no vtec and low compression. The Z6 has small combustion cambers and dished pistions, so add a CRX head with kinda big combustion cambers to a block with dished pistions and you get... LOW COMPRESSION, perfect with a turbo, right ?

I figured one time, and I think it was like 8.1/1 compression !!

Any comments or ideas as to how well this would work ?

I just did an entire D16Z6 swap into my civic...hehe..

why are people that do mini me swaps always talking about compression.. ---- compression u dont need to worry about it on a d series motor. unless you have some aftermarket high compression pistons or a head that milled to hell. many pro racers now days are running higher compression and less boost..

mini-me has a really high compression ratio of 11:1, not ideal for turbo but can be done with proper tuning like anything else. Keep the poundage low, and slap some injectors and an afc in it.

11:1 compression with a mini-me....how does the compression jump from 9 something to 11:1

cause your putting 2 different engines together simple...

I would luv a compression ratio of 11:1...
damnn that's some nice power all over the powerband

I think putting a non-vtec head on your Z6 block would be a waste of time. There are a bunch of people on this site boosting stock Z6 motors with no problems. It already has low compression anyways 9.2:1

20psi on pump gas would be cool, not 15psi with race gas.

The "un-mini me" would drop the compression like crazy. But I want something that is kinda fast all the time, not just when I "prep" it for the track, and put 116oct. in it.

put some toulene in it and you can up the boost hehehehe
