Default Lt1 swap in a 94 3.4 5 speed

What needs to be changed? The guys also wants to use the v6 5speed but I told him I was pretty sure that wouldn't work.

That wouldn't work. If they even could find a bellhousing to mate it up, I'm sure it wouldn't last long. He'll need a new K-Member for a V8, and I wouldn't doubt a new trans cross member for either the M6 or A4, depending on what he ends up using.

-most accessories/bracketry
-engine k-member
-I had drum brakes so I swapped to LS1's all around
-fuel pump
-exhaust components

Electronically:

-engine harness
-I used the 95 engine bay harness and have adapted it to connect to the interior harness and engine harness through the factory plug ins
-PCM
-most will say you need to swap steering colums due to vats but if you get a basic tune before start up you can just tune out vats.



That's the basic jist of things. If you have any specific questions feel free to PM me. It's been a long process and this is just what I can come up with in 5 minutes of sitting here.

I would also suggest replacing anything that you don't want to have to go in and replace later on. ie: motor mounts, oil sending unit, if you're doing headers etc...anything that will be easier to do now while it's out then later when you'll have to struggle. haha.
