Questions about swapping a 6 bolt into a 94 GSX with a 7 bolt

[hooter_rocks]

I currently have a 7 bolt 2.0 turbo engine in my 94 eclipse gsx. I would like to purchase a used 6 bolt engine.

Can someone please link some reputable companies for buying said engine? This seems to be the most difficult part, and I'm afraid I will get screwed with a terrible engine. If you've had a good experience buying the same engine from a company I'd appreciate you sharing it.

Does the 6 bolt drop right in or will I need to make modifications?

I have an Evo 3 exaust manifold and turbo on there now, will that work with a 6 bolt?

Is this a difficult task that I should let a mechanic do, or would I be able to do this with a couple of friends?

Does anyone have any advice about the swap?

94 is a 1G.....

shouldn't be too hard, since 1G's came with both 6 and 7-bolts depending on the year. i'm guessing it should be a direct swap.

 

[DGajre777]

My bad, I didn't pay attention to the 94 eclipse GSX. I figured you were talking about a 2G

1G 7bolt uses:
6bolt Head
6bolt Waterpump
7bolt Oil pump
7bolt Oil pan
7bolt Crank
7bolt Rods
7bolt Pistons 7.8:1 compression

It is a direct swap.
