ok I researched as much as possible and the only thing I can come up with is,,, change my automatic to a manual, but really I DON'T want to... It's a daily driver, I go to the strip maybe once every other weekend FOR FUN, and I don't want to do a manual setup if I don't have to... So can someone give me more advice about what stock tranny can hold up to 450 rwhp comfortable??? I'm staying on stock twins, so whatever HP I can make (SAFE) with stock twins is what I'll be pushing so I figure around 375rwhp would be a fair judgment, but just to be safe let's say 430rwhp because I've seen a guy making around 4ish.. SO what automatic tranny do you guys suggest or is there one??? Am I SOL and I need to just build mine or can I buy say an older model supra one and will it ALL hook up properly? I'm so lost, please help, im pulling my hair out trying to figure this out.. I have a 1jz swap in a SC400. Thanks.

I'm wondering the same thing. I've been told the auto SC can hold up to around 400 rwhp max. I have a tranny cooler, but I know the stock tranny has its limit. I'd love to break this barrier with a built tranny. Does anyone have any sources or info on this?
