3100 - 3.1L swap

[95 Cutlass]

I have a 1995 Cutlass Supreme SE with a locked up 3100 and have access to a 1994 3.1L from a Lumina. What modifications am I going to have to make to the 94 or is it going to bolt right up? Any input would be greatly appreciated.

Greetings, and welcome to the forum!

I'd suggest finding another 3100 at a local wrecking yard. Try checking on http://car-part.com/
That engine was used in many GM mid size cars from 94-95. It shouldn't be hard to find one for less than $600.

The 3100 has more HP/Torque and better gas millage.

I wonder if they guys on www.60degreev6.com ever discussed this?

if your serious about the swap look forward to swapping the harness, ECU, possibly the tranny... its more work than your possible planning, just find abother 3100

The 3100 is basically the the 2nd generation 3.1, They are both 60 degree v6's, the belhousings/tranny's should bolt right up. But it is true that finding another 3100 would be best.
