Engine Swap Questions
 

alright so after a month now of workin on my 83' i finally had it ready to put back together, take my head to the shop only to find out its trash. so i set out to look for a new head and find a local selling a complete engine harness and all belt driven accesories.
now my problem, the engine is from a 86. i gave a call to carl's place, the local porsche shop and he wants to modify my car to fit it. i know from reading posts here that all the work he wants to do is not required and that its more for aesthetics.
my question is what do i need to change besides the dme, engine harness, and longer fuel lines? so far ive read that everything else mounts up just the same.

Just put on your old fuel rail and sensors to utilize your old harness and fuel lines.

Just my .02 worth.

Oh, didn't even think of goin that way. But the 86 has automatic belt tensioning, how will I adapt that without switching the dme?

1) The 86 doesn't have automatic belt tensioning, that started in 87,'

2) The DME doesn't have anything to do with the tensioning.

ah, the PO of the engine had stated it had the auto tensioning, so the just switching the fuel rails and sensors should be ok? would i still need longer fuel lines since the 86 lines came from the ps and mine come from ds.

My late 86 which I bought brand new did have an autotensioner so it actually started sometime in 86 but that has nothing to do with what you are trying to do. I agree with Nick and George, put your old stuff back on...that's all you have to do.

awesome, thanks for all the info. ill post an update when i start thrown that babd boy back together this weekend.
