Hello, I am planning to build a 2JZ GE currently with no specific power goal but I would say it would range from 400-600 H to the wheel. I assume the a341e automatic tranny which the 1999 sc300 comes with does not hold this power or at the very least could be very unreliable. With this said, Apart from the V160 supra tranny which is typically quite expensive, what are some budget manual tranny's that could do the job? both stock like a stock v160 and built. (obviously I am trying to minimize how much I have to "build" or spend on one.

 

Welcome aboard.
I'm moving your thread the 2nd GS300 section because there's a strong support there.

There's also the SC300/400 section you can check out.

400-600 is a pretty huge range.
You have no other information about your build so I'm just going to list some transmissions.
