Default Auto vs. manual trans.

I know that there are two types of manual transmissions for the 86.5 to 92 Supra's, but I was curious about the strength of the automatic trans. Are there two types of these also to cope with the extra torque and power of a turbo engine, or does the one type handle the power just fine? I was just curious because I have a good auto trans when I did my engine/transmission swap.

If I ever got a turbo with the auto tranny and decided to boost the power, can you just hold the pedal to the floor and let it do all the work for you? Missing a gear in a high horsepower car is not fun and I have done it a few times in my manual/NA car.

Just curious about it though. I don't have any car in mind yet, but if the opportunity comes up it would be nice to know and I know there must be a few out there with extra horsepower connected to the auto trans.

Thanks
Russ

I believe the stock AT can handle BPU upgrades, but most people making big power with an AT go with a turbo 400.

Thanks kwnate. By the turbo 400 are you talking about a GM product? And is there an adapter kit? You see the reason I am asking is that I am thinking of sticking a chevy 350 in a donor car I have. I have the stock auto trans, but no stock engine. I got a good running 87 with the parts from this other car. The 86.5 car is in good shape and I hate to see it sit and rot so that is when the 350 swap came to mind.


Anyone here ever put an american engine in one of these or know a web site where someone has done so?

Thanks

Russ

Russ,

You seem like a sensible guy!!!! I beg of you please dont put a v8 carburated chevy into your parts/doner car. To me, and I am sure many other Supra lovers, that would be like putting a Harley twin into a Suzuki Busa. Take what you need from the car and sell it to somone that needs it. Or part it out, some of us may need stuff you dont. Remember ebay is your friend. I dont want to sound like a jerk but no Supra deserves a Chevrolet fate. We spend most of our time trying to beat the chevy v8 at the track to have one invade our own is criminal.

Best of luck

DA SOUP

Nothin wrong with chevy. I have 2 of em But you could probably put a 1jz it it for the price of a 350 and 400 tranny. Lots of fab work im sure.

Well it is just an option and Chevy performance parts are so much cheaper too. And you know the old saying, "you can't beat cubic inches"! Nothing on the drawing board yet that is why I am asking about the transmissions. I know there is a lot of fabrication to be done, but this sort of stuff is being done all the time, modifying cars I mean. I have seen a 350 in a motorcycle and it looks pretty cool, expensive but very interesting and heavy too.
