2.3T into an 88 5.0L?

well i think the input shaft is longer on the 5.0 so i dont think you can use the 5.0 tranny....the engine harness and computer will have to go...i think it is more of a pain to swap over a 5.0 vs a already 2.3L plus i can only see 100-200$max for a used 5.0 motor.....

I think the V8 shaft is only longer on the 94 and later T5's.

I don't believe you can swap the shafts. Something about the gear on the 4cyl shaft vs. its counter in the V8 box. Double check me to make sure, but If I remember right, that's the deal.

There's a pilot bushing that's being used to stuff the larger input shaft into the tiny crank. It's pretty thin and reviews have been mixed.

The fuel line runs up the opposite side of the car. No big deal really, just another thing to overcome. The vac tree is different, but I don't think its that big of a deal. Vacuum is vacuum regardless of the shape of the tree so long as ported and manifold vacuum are routed accordingly.

If the car has A/C and you're planning to keep A/C, the hoses/drier/and possibly the compressor are different. The condensor is the same though.

You'll need an electric fan since the 5.0's fan was engine driven.

As for the mounts, The k-members are the same, but the rubber mounts are different. I can't say for fact if the perches on the k-member are different between the two. I'd venture to guess the perches are the same. With as many guys that have done the opposite of what you propose without the perches being mentioned its a safe bet to say they're the same.

I'm just rattling off the top of my head so I may have missed some things and there's certainly things I don't know about. I hope this is of some help.
