Hey just bought an 88 rx7 n/a and was getting ready to buy the turbo 13b motor and had a couple of questions and hoped to get a couple answers:



How difficult is the swap?

Is there any wiring Changes?

How much psi can the stock motor take?



Thanks Matt.

 

well i had an s5 n/a and the swap to a s5 turbo motor and it was simple the only hard parts for me was finding the halve shafts that would fit an 10th anniverisary diff. but i heard to swap an s5 turbo into an s4 na it is going to be alot of wiring issues, someone in this forum has a list of what things needed to be replaced i am sure he will give it to you.
