First post, might as well make it interesting. I've got a 420a engine in my 98 eclipse (2.0L non turbo) and was just wondering if the 4G eclipse v6 3.8L would fit in the old body. I'm sure it would need a lot of work but I'm just wondering if there is enough room to do it. Its a popular engine and I'm sure there are quite a few damanged galants out there that could be used as a donar car. I really do like the style of the body on the 2G eclipse, which is why I was looking into options to improve its performance vs. just trading in the 2G.

 

not without extensive modifications to the frame and firewall.

 

Nope, look for a turbo kit or a different car, I know from experance.

 

They have a turbo kit at Hahns that will get you plenty of power with out much modding, and they include everthing in the kit. And if you want to increase it, they sell the other parts to increase it even more such as pistons and connecting rods. I also have a 2g eclipse and will be purchasing this kit soon hopefully.

the 420A engine mount locations should be the same as the 6g74/75.
