anyone know the pro/cons of doing a "1.5" 2jz swap
ok essentially this is the 2jz block with the 1jz head. i recently read a article on it and wondered what the pros/cons of doing this swap are.....or why would they go this route and not just do a 2jz swap? no i'll tell you it wasn't for cost as its in a semi pro drifters car so we can exclude that idea! i think car makes upwards of 900 hp but might be 600. will check when i get home and verify

if the 1j has better flowing heads then thats your answer, kind of like some guys will bolt GE heads on a GTE

It's more of a cost and amount of work needed reasoning. If the car came from the factory with a 1JZ(like in a Soarer), and you want more displacement...it's cheaper just to bolt on a 2JZ bottom end rather than swapping out the whole engine. Also, swapping the whole engine will involve having to rebuild a whole new wiring harness to work on the 2JZGTE head. For a while some people were saying that the 1J head flowed better, but I think that theory has been put to rest.

i always heard the 1jz heads flowed better than the 2jz gte heads. the GE heads do flow more, however until recently, you couldnt get any cams for them. cams are available for the 1jz's though. could also to be different, never know.
