I got a great deal on new diamond pistons and rings for my "budget" build. But they are notched for a 4v head. Will they still work with my 2v heads?? I snatched them up, I can gain my money back if they won't work. Will it effect compression?
4v pistons usually have a smaller dish so do you know what the dish size is on that piston? 2vs are usually around -18cc dish those from a glance seem under -5cc..with those reliefs it could bleed off compression by a few ccs.
They would work and probably provide a bit higher compression as well....I gain 40 rwhp and to from stock gt pistons to -4.66cc cobra pistons..CR went from 9.6to1 to 11.34 to1....really wakes up the car bit would need a tune..
