Engine Swap in 92' Grand Prix?

Question

I Currently own a running 1992 pontiac Grand Prix. And it has a 3.1l engine in it and i was wondering what other engines i could put in this car cause the 3.1 in it is running horrible. Thanks

Answer 1

you wouldnt want to replace it for running bad it could be something simple.   Changing to a different engines in ur car could be a lot harder and more expensive than the car is worth.

Answer 2

yup a 3.4 should fit right in there

Answer 3

Find out what's wrong with it first. If it's something terminal then think about changing it. You obviously know that you can put another 3.1 in it, and this would be the simplest option. However, If you can't find a good 3.1, the 3.4 and 3.8 could go into it with minimal hassle. I believe they were both factory options in this car at some point. I'm sure the 3.4 was.
