hey guys im not new to the car scene i usualy work on hondas and rx7s but i just bought a 1990 supra turbo today car is a automatic i know some stuff about boost from the single cam hondas i had turbo but supras are new to me i just had a couple quick questions are the at trannies good for high power or is it better to swap a manual in and how much power do u thik they can hold i plan on keeping this car for a long time cause i got it real cheap (900bux) and the body is perfect just needs to be repainted and needs some new seats also how much boost can u run on the stock motor with proper tunning and are their any programs out der where you can chip the ecu like crome & uberdata like you do on hondas thanks guys :)

auto trannies won't last too long under high power on MKIII's. You can either get a built auto tranny to hold high hp or just swap in a R154.
The most boost I heard you can run SAFELY on pump gas(93 oct) is about 18 psi.

R154's aren't too much, around $4-700 for a used one.
