here it is, my finished cylinderhead (better pics are comming later)
intake valve is 38mm (stock 35mm)
exhaust valve is 34mm (stock 31mm)
head flows from intake max 272hp
exhaus 133hp
(these measurements are tested with nonturbo use flowing meter).
Cool project man, i tinkered with one out at pic-a-part and took the intake, exhaust mani, turbo, and all the little bit in hoping to either do my own project on the m20 or sell the parts. but anyway cool stuff.
Here are new pics about engine failure...
stock gasket exploded again...
Under construction
I found something interesting from my intake manifold... oops...
