Thanks for the replies, ive got some reading to do.
In a nutshell, could i use a 2T block, with a 3TGTE head? or is it better to use a 3TGTE block with 2TG head, and 3T manifolds? Do all models of the T series engine (head and block) match up?
Im a big fan of forced induction, but ive never had a highly strung NA engine before. Which option (4a vs hybrid) would be more liveable with vs power? reliability isnt a word any of my present car(s) can spell.
