Engine compatibility.

has anyone ever tried putting a 3.4 in a car that was made for a 3.1?

[SigEpCutlass]

people do swaps like that here before...trying doing a search topic.

[MIKELABZ]

did a search and no dice on swapping engines with a 3.1 and 3.4, but plenty of info on swapping with corvettes and such...

do a search on here not a internet search

A 3.1/3.4 swap is not that difficult since the cars are already made to accomidate the engine. I'm doing my own Turbo 3.4 swap pretty soon.

[White93z34]

since your car is likely a 3100 car a 3400 swap would be cake.

Im assuming hes talking about a 3.4 DOHC, its not to hard, its all bolt in stuff.

[MIKELABZ]

what other engines will fit into a 1994 cutlass supreme besides another cutlass engine?

You mean GM motor wise?

 

Aren't the subframes a tad different on the 3.4's than the 3.1 and 3100 cars? (along with the 2.8 for that matter)

 

 

You could look into the 3400 (larger version of the 3100) as a possibility.

 

But, other than the infamous cold start 3100 rattle boogy, I love the 3100.

 

You could always look for a newer 3100, say one with 175hp and more torque (not sure the ratings on newer 3100s).

 

I've also heard about the 3.8/3800 being a possibility, but I think it will require more work than the 3.4 (LQ1). Thoughts?

A Series II 3800 swap is possible in a 1994+ (minus Lumina [95+]), since they also use the Serial Data Bus. Anything below 1994 would be.. next to impossible to say the least.
