Well, GE heads flow better than GTE heads, not that mine remained standard after oversized valves and porting work done by myself
The main reason was at the time GE engines were around £200 for a complete engine, far cheaper and given the small number of differences between the two (except that the GTE engines go for £1500) and as i fabricate, design, prototype and build everything myself
My question to you hellboy is, why would I want to just drop in a TT ?
Also I quite enjoyed having a 750rwhp daily that's much more fun at half the price of a tt, even at bpu
My next supra will infact be a fresh import tt6 , that I'll eventuall big single with all my own parts
