mod the block and head to take bigger head studs and turbo kit it and standalone ecu map make over 250 hp the only way you will see results worth making a video about tbf shite engine over engineering in some places eg valve train, and some stupid weak points eg 6 m10 head bolts in centre and outer bolts are like m8 wtf .... no wonder head gaskets fail.. big ports in head should make decent power if crank rods can cope
