You're right about not having to replace the whole motor or bottom end or even the head. But in the starting thread he talked about wanting to do low 12, 1/4 mile runs, right?
So I gave him the option of throwing a 2.4l into the engine bay.

 

You can do low 12's with the 4G63 just needs a bit of work and a bunch of $ to pull it off. I'd keep the block that's in there and rebuild it for performance Though I don't think I'll be able to do the same w mine I think a valve went thru a piston on my engine

 

Well if you decide to keep the block I would recommend using the 1g rods/pistion. But keep the 2g head because it flows more then 1g.

 

actually the 1g head flows a lot better than a 2g head, for a much better top end. 2g heads are small, so they have better low end power and die towards redline. but you arent noticing that he has a 97 gs, which means he has a dodge neon motor and not a 4g63. That motor will never run 12's with $5000. He should fix the motor and sell it if he wants to be fast.

 

NEW TO THE WHOLE THING WHAT IS THE 4G63?

 

NEW TO THE WHOLE SCENE,WHAT IS THE 4G63?

 

Engine code for some DSM's

 

The 4G63 is a popular engine block that was stock in most 90+ Eclipses and the Gallant's I believe was teh other car that used it alot. It's a rather popular 4 cylinder engine can easily and readily find performance parts for it and upgrade to get decent power out of it.
