Engine Swap
Afraid this may be a newbie question, but here goes.
I have a 86 GXL that's been sitting for the past 8 years that I would like to restore. Instead of bothering with the engine in there, I was contemplating finding a rotary engine with the turbo built in and dropping it in. Will an engine from any Second Generation turbo rx-7 fit my 86, or are there any situations I should be aware of? |
If you plan to run a turbo 13b on your car, you will need to swap out the entire drivetrain (tranny, driveshaft, diff).
|
not nessicarily the diff. do u have lsd? n it depends on which series of engine u have (s4 is what u have) u need to find the same series. u can go series 5 but u'll still have to keep ur s4 electronics. so look around n find an s4 with tranny n all that shit n it should go in easily.
|
Was lookin around on E-bay, saw a 3rd Gen Twin Turbo Engine with 5-spd transmission included. I take it this is along the lines of what I'm looking for? And should it matter that it's a JDM engine or is it all the same?
|
wrong generation bud. u could do it and it'd be sweet, but its a ton of work. i dont even know where to start. n the jdm engines usually will have high miles n will need to be rebuilt :(
|
MWMburton- you mentioned something about swapping an s5 into an 86 and u would keep the electrical components such as what????
|
You can turbo the NA and just swap the drivetrain parts. It's going to be a lot of work either way.
Hope you like working on the car. (Wrong car to own if you don't) :D |

well slap my ass n call me sally. i stand corrected. how much reliablity did ur friend get out of it?
|
MWMburton, wrong generation I know but that's the point. Heard somewhere that the thirdgen twin turbo runs better in the second gen chassis. I realize it's going to be difficult to do, and it'll probly have to be sometime in the future but I wanna give it a go. Any guides I should read before starting, what am I gonna hafta buy? I think I may end up rebuilding the engine before I even swap it, just to avoid problems later on.
|
i dunno im doing a lotta research n talking to a lot of people for info on my swap, i suggest u do the same. do a lot of research through all the forums cause if u post something all u'll get is experianced guys telling u to go research, lol.
|
Good advice... heh, thanks
|
when u get done with the swap it'll be a very sick car! but, this is going to cost a pretty penny. u need a good engine n tranny n i suggest trying to find an uncut wiring harness n then u'll need to but a custom driveline or u could upgrade to the fd diff which is viscous but its lsd. n u'll probably want fmic n all that shit, bov or dv n down pipe, exhuast, ect.
