Um... What is an rv26 and why the HELL is it in a supra?
Last I checked, Supra's came with either a 7m, a 1jz, or a 2jz.
I would hope that a person with your extremely limited knowledge on engines would refrain from attempting an engine swap.
BTW I believe the engine you're talking about, an RB26dett, is from a SKYLINE. Learn what the hell you speak of. Thanks.
