Hi. I have a 93 sc300 auto. How much rhp could I possibly get with the stock tranny in the sc? This is my daily driver but I want to get around 350 rhp and have it be reliable.

Also, would a rebuilt auto trans from some company be able to do > 400 rhp? Which company would you recommend?

I'm new to this stuff so any help will be appreciated.

hmm around 300 is safe i think around 400-500 i seen auto trans granade quite a bit i'd recommend contacting either kean at bl for a possible built auto trans or one from pat at level 10

Thanks for the replies guys. I'm hoping I can get the R154 swap so I don't need to worry too much, but if I can't get one I think i'll try to get the rebuilt bl trans.

350 is perfectly fine with a good tranny cooler.

If you plan on going up to the 400's or 500's you can just swap a 1jz auto tranny and you're good to go. They're cheap and its a direct swap from what I hear.

you'd need a adapter plate if i remember right for that

The 1jz autos are good for no more than 350rwhp with a cooler and shift kit.
Im trying to gather info on built autos on a 1jz.
