i have 3 rx7 engines one is a t2.
i want to rebuild the t2 motor and while doing that put the t2 stuff(turbo and intake etc) on the na. i looked at the swap to do it and was wondering if the t2 block is different than the na block like bold patterns and where the intakes go and such. i am asking this cause in the write up, u have to jb weld stuff in the t2 manifolds and etc. arent the engine blocks pretty much the same. does anybody else have a better write up or way to do the swap so later i can put the t2 stuff back on the original engine back on.

 

Manifolds should bolt up, you will have trouble getting oil on the N-A Block (and even more trouble getting rid of the oil out of the turbo.)

To find out all the issues, read:

This is the best place to start.

Good luck with the swap.
