I like my 99 Galant GTZ V6,but with over 160,000 miles it may be getting close to finding a car with better gas mileage the way things are these days.I was considering keeping it and swapping in a new replacement 3.0 V6. But now,I'm forced tp consider swapping in what most 99's had,the 4 cylinder. But would it match up to the 4 spd auto I have? Or would this whole idea not be worth the money,& I should just look for another car altogether?? I found this engine listed on Ebay today-->> http://cgi.ebay.com/ebaymotors/98-02-Mitsu...em300228487933& -Any advice?

i have yet to see a V6 that will pit into a stock 4 cylinder engine bay, and vise versa. its not a common thing, and in mitsubishi's i have never seen it. i would say no.

you might be better off trading your car in for a 4 cylinder Galant. make sure its got the 2.4L 4G64 model motor in it, and you will be looking at a very nice motor that can handle a lot of abuse, and it also has a huge HP potential. these motors are known to handle 15psi turbo boost on stock internals. also you can swap the SOHC head for a DOHC 4G63t heads off of the EVO and have that much better potential.

Do the math and tell me if its worth while - the answer will be no.
