Default i have a question in dire need of answering

alright i need some advice, ive heard that hks head gasket and arp head bolts are the best combo. but i have a bigger dilema mines automatic. i need to know if the stock 7mge transmission will fit into a 7mgte. i know the trannys are the same a340e but i dont know if they have different ratios or different internals. i need to know caus ei found a running supra for 400 bucks but i dont know if the n/a tranny will do the job for my turbo engine??? please get to me

I would think not. The NA manual tranny doesn't work for the turbo cars, so I don't think the NA automatic would work for the turbo car. Not strong enough. Or different lengths.

actually i found out today, the automatic is the same in both models a340e but in the manual versions the non turbod supra is a w58 and it is weak, the one in the turbo is a r156 and it has very different internals so the autos are the same but the manuals arnt

the manual trannies are different but you can still use a non-turbo tranny w/ a turbo motor and viseversa. the only thing about that is that the w58 doesn't hold power like the r154

qyeah weaker internals so i would rather find a turbo tranny. but if anyone needs a good running supra for a g i know where one is, its been wrecked maybe like 3g damage but it runs and you can prolly get it for like 800 if you want to drive to asheville

the autos on the gte might be a little stronger but i cant confirm that, the w58 is not by any means weak, it can hold up to 400hp, toyota doesnt make weak trannies, and its r154, not r156, that can hold loads of hp, front half of the driveshafts are all different on all models

yes i agree the trannys are both built powerful but i would much rathyer have the r154 because of the internals they built the r154 for the turbo and it it stronger then the w58 so i would rather go with the r154
