Hey guys, I know this is probly the most asked question among the Rx7 guys but I know alot of people do it so im looking for some help.

I have a JSpec s5 turbo motor that im going to put into my 88 GXL. I read on rotary resurrection that the best thing to do is to replace a bunch of things on the motor and use a S4 harness and S4 ECU so the dash harness plugs in. So I have all of that Including another S4 Turbo motor as a donor for the parts. Im curiouse if there is any better way of doing such a swap with out the hassle of swapping over the front cover which requires pulling off the essentric shaft pully. Any help would be greatly appreciated!

Also if anyone can tell me how they did their S5 into an S4 turbo swap let me know. Thanks Guys.

 

Help guys come on

 

Sorry man, no easy way to go from s4 to s5, comes with having an entirely new wiring harness
