VVT Supertech interference
Forged piston & rod Turbo build w/ possible VVT head. I was planning on using the Supertech 9:5 to1 pistons, 83.5mm. Has Supertech changed the their valve relief cuts since the thread i read from 6 years ago?
Stock OEM 01-05 VVT head w/ firmer springs. stock OEM valve size( not oversized). Standard head gasket, block and head not decked to less than .005 off each.
Has anyone had interference problems with the valves hitting at TDC, max VVT Cam advance with these pistons?
if the kevlar timing belt breaks, this will now be an interference engine.
