I have a d15 block with a d16z6 head and was planing on swaping in a new camshaft but then me and a bud started talking about my setup. wonder,how my valve reliefs are gonna be with a bigger cam....i would really hate to lose my motor because of valves hitting the pistons.
I have a 1.5liter bottom end. My pistons have a different valve relief in them compared to the z6 blocks so i was wondering if anyone has this same setup and have used this camshaft before, and had any problems at all.
any input on this would help me out a lot , thanx

 

should be fine as long as there are 16 valve releifs...

 

Depends on the d15 block that you used. D15b6(hf) only has 8 valve reliefs. But I guess if you have a z6 head on, then you probably have 16 valve reliefs, I dont know if a 16 valve head works on 8 valve pistons. I would like to know this also.

 

its on a d15b7 bottem end (civic dx)

 

Yeah, I am an idiot, I should of looked at your sig. You might test to see how much clearance you got right now. Use some silly putty on the piston to check it. There should be some info on how much the cam will change your clearance.
