i know wat it is thats why i said im leaning towards it 1jz head flows better
i just herd alot about the 1jz being a awsom engine i dont get it cuz the 1jz has no torque and the supra is a heave ass boat but my but is all about the 1jz, i figure 2jz /1.5jz would match up better but my bud wont belive a word i say so i posted this for him

I come from a land down under
1jz head flowing better is yet another Supra Urban Myth......
(flow tests were done to prove otherwise the 1jz head had higher port velocity but less flow)

2JZ would be my choice.
