We have just finished building a fully forged internal Version 4 STI WRX engine for a customer. The build includes after market cams, head studs, block studs, ported and polished heads, metal head gasket, Crower heavy duty valve springs and titanium retainers etc...
I must admit that the WRX engine is not a pretty thing to look at, but the customer is going to be more than happy with its performance when it's in the car and tuned.
