Hey guys, the photos from the original K20A2->K20A3 cam thread seems to be dead.

Just wondering if anyone had success with Z3 Civic Si's engine cams+rocker swap into the base model. Would K20A2's rockers fit with the Z3's cams as well?

Cheers.

Edit: I can get K20Z3 cams+spring+retainer+spring base for $100.

Should all fit it's all the same "k series", just the base head doesn't have lost motion springs. You'll need to reverse some pins on the rocker assembly Btw you need kpro to run that kind of setup plus a tune

Yeah. I found out the auto's ECU doesn't have enough memory for that.

Trashy. :/
