Wiseco Piston compatibility with VVT
 
Hi !

I'm re-building up a bit of frankenstein Turbo motor, and will be looking to put in some .040 over (84mm) Wiseco pistions. the Block is from a 94, and the head is a VVT head. The Wiseco man wasn't able to tell me if my valve pockets would be OK or not with this setup, so I thought I'd see if anybody has experience with this sort of setup...

Thanks !

If it means anything to you, I'm using Supertech pistons with +1mm oversized valves in a 94 block and VVT head.

That being said, browsing through vendor listings, it looks like pistons for 1.8L are compatible for 94-05

See fab9tuning.com for instance

Same motor. Roll on.

With stock VVT cam you will most probably have a lot of clearance even at full advance.
My setup however needs to be blocked at 42 degrees advance or the valves will hit, but why would you by that stupid ;).
Measuring/testing is knowing...

Cool, thanks - so do you have a modified VVT cam with higher lift or something ?

10.7mm lift and 305 degree duration.
I don't remember the min/max lift values at TDC, that's what a good builder is for :D
