Motor is already built.its a s4 turbo 4port block,streetport,s4 n/a rotating assembly with all new seals and springs.he wants to run it all motor but we did modify the front cover for a turbo oil return line in case he decides to go turbo in the future.going to use a fc rx7 stock Ecu.here some pics of the motor during the build.

Looks more narrow than a repu and measured and confirmed it's actually right around 3" narrow.so probably need to fab up a header for it.

I got a hold of an rx3 crossmember and modified a bit so it fit the truck.worked out pretty good I think.



But damn it's going to be some tight space for the header.

If you can, I would like to see more detail on how you modified the shifter on the transmission.

Thanks Allen

I was able to fab up the trans mount using the original mount that came with truck.the engine ended up a bit high so I had to mod the engine bracket so it can drop 1" and be nice and leveled.





Engine and transmission brackets are all welded up already and getting cleaned up for paint.also finishing grinding off the old piston mounts off the frame so the frame can get painted black.once all that is ready we can drop the new motor and trans in permanently.i will keep you guys updated.

Managed to get some more work done to it.i had a 86-91 rx7 13b header that I modified so it fits the tight engine bay on the truck.also got a fd upper intake manifold ported so it bolts up directly to the s4 turbo lower intake manifold.got some dual radiator fans mounted also.heres some pics

Getting closer to start up.
Managed to wire up the rx7 ecu into it and it is almost ready to fire up
Just gotta do a few small things here and there and it's good to go.
