1.5 to a 1.6
2X on the complete Z6. I've got a 1.5 (D15Z1) with a Z6 head. Runs good but not much power. Another option is to add a turbo to the mini-me (Z1 is low compression-good for turbo) but I don't know about the $$.
you dont have a minime the d15z1 is a vtec-e block they are 90 hp engines. now if you had a y7 or a b7 block with that head then you would have alot better power.
Hmmm, I thought a minime was putting a different head on a motor than what came from factory.....Is it a vtec head on a non vtec motor??? Anyway are there advantages to having a Y7 or B7 minime over the stock z6??
yes a mini me is putting a vtec head on a non vtec block, the advatage of doing this instead of just a full vtec motor is higher compression and more hp. also most of the time its cheaper to just put a head on the to swap a full motor
