i have na 91 rx7 and i wanted to swap in a s5 turbo ii enigine in it what would i have to change out for it to work? harness? any other components? any help is greatly appreciated thank u

 

This question Pops up more than Kardashian Videos.
Engine,you can use the s5 N/A harness with modification(lengthen some sensor wires).
Trans is up to you.You need the appropriate flywheel for the transmission and the starter,clutch slave.
You can keep the N/A trans and hope you don''t bust it,or get a TII trans(all the junk to go on it) and then a conversion shaft to go to N/a Diff..
OR get the TII diff and shafts.
SEE why this is a Pain to answer?too many alternatives.
Hit a Post by RotaryRocket88 and look at his SIG.It has a link to this subject.

 

See the NON-Turbo to TURBO Conversion here:
Rotary Resurrection home of the budget rebuild.

 

well i looked at the link and i thought maybe i just just buy a turbo 11

 

That would be my recommendation. The conversion isn't worth the effort unless there is something very special about your car, such as an $8,000 paint job, or maybe it's a convertible.

The other option is to just enjoy the car as-is. The car was originally designed around the NA engine, and the NA cars are more fun to handle around town and on the autocross track.

 

Swaps are nice once all the details have been sorted out. As mentioned above, sometimes just easier to avoid all the sorting.
