big bore kit for 420a

[mdost03]

I would say stick with the 420a. It's a nice platform to work with. There are more people than you think building them up. I have put a turbo on mine about a month ago and am pushing about 6 psi. It's pretty quick now, can keep up with slightly modded gst's.

You are right, a 4G63 swap is not good for our cars. You might as well swap in a Toyota or Honda or any other type of engine because it would take about the same amount of work. The 420a is a Dodge/Chrysler engine while the 4G63 is a Mitsubishi engine. Everything is basically different between the two.

I pieced together my turbo kit for about $1400. It's still on stock internals so anything more than 8-10 psi is not recommended. If you would like more info about what to do, give me a pm or check out 2GNT.com or DSMTuners.com under the 420a section and search away. Plenty of info for what you are wanting to do.
