Hi, I'm to this board. I was thinking of buying a 91 T5 car with the intentions of putting 415 or 427 small block in it. It would be a street car. Now I know the T5 will not handle this torque. Could I use a Tremec TKO trans instead? I can't seem to find any info on this swap. What is involved? I am thinking it should be easier since the car is already a stick.

I thought about a T56, but it seems like a bigger hassle.

Also, when a trans is rated at say 450fts of torque, is that for the final gear? I heard this and the first gears are actually rated at much more. Is this true.

I welcome all comments.

 

To tell ya the truth I would wait until you break the T5 I have been waiting since 86 and it hasnt happened yet and its been through alot JMO and 2cents

 

have you tried the search function? you ought to be able to find lot of threads related to the tko
