im thinking of putting a 89=91 13bt in my 85 gsl that i got for free it has no eng. or trans. in it right now.

just want to know a list of parts i may need or problems i might run into. if anyone has done this swap before please let me know if its worth it.

No, no one has ever done that swap before. Lead the way!



hahaha j/k do a search, there is an actual swap section on this forum. Take a read through it and come back with some more specific questions. Welcome to nopistons.

people have been putting the 13b into 12a cars since the 13b came out!



on a 1st gen you need to get an oil pan, front cover, racing beat makes a 12a to 13b crossmember....

what about engine management will the stock ecu and wiring harness from the s5 work in the fb. if it does what mods do i have to do to make it work

z-beater 06-22-2007 01:33 PM

You will have to re-wire the car to accept the S5 TII harness. And yes the stock ECU will work.



Or you can spend about 1k and just put a PFC in there. https://www.nopistons.com/forums/pub...IR#>/smile.gif

It is a FD computer. But it will also accept a S-5 harness. You need an S-5 harness or S-6, FD ignitor, Fd ait, FD map sensor, the rest can be S-5 electronics. You have to repinn the harness a little bit, Wire in the ignitor, power up the harness yada yada. I think I was like the 2nd or 3rd guy to do it. Cheap standalone. I actually did a qucik thread on it over in the nw section when I did my swap this winter. Search for standalone for less than a grand. The power fc is a great computer, that lots of rotary shops can tune.

**** I plugged in the computer, zeroed it out, started up the car, then I drove it 160 miles to portland to get tuned. Which is awesome, because I know alot of folks who have to trailer their 7's to the shop for a start up tune.
