I would've just gone out & bought another 86kw 4AGE ... from experience, I know that any FWD 4AGE can be bought (less loom, computer what not) for $400 or so. You can then spend $500 to get someone to just install it where your old one used to be.
How do I know? Cuz that's what happened to me engine conversion first time round. Still, I now know that I can cane my engine until it's driven to the grave as long as I have a spare grand or so in me pocket ...
If you do buy a 100kw, you might as well just spend that little bit extra fitting the whole thing. It'd probably be cheaper than using some existing 86kw parts. It'll also pull harder and have better acceleration ...
