Hi all, I’m trying to put together a list of things that I’ll need for my swap, in addition to things I’ll want to replace on the donor engine. I’d like some feedback for which things I shouldn’t bother replacing, and what I need to upgrade/update in order to put an ‘i’ motor into my 9/86 production 325.
Here’s a list of what I have so far.
new parts
*valve cover gasket
*head gasket
*oil pan gasket
*intake manifold gasket
*exhaust manifold gasket
*water pump gasket
*timing belt
*throttle cable
*spark plugs
*distributor cap
*ignition rotor
*ignition wires
*torx head bolts
*exhaust heat shields
*high flow cats
used parts if available
urethane or delrin motor mounts
3.73 lsd (per spec e30 rules)
stock exhaust
ECU
urethane or delrin tranny mounts
’i’ tachomter
fuel pump
Do I also need to get a wiring harness from an i car? How about the AFM or throttle body? Any other gotchas I haven’t thought of?
