Looking to find a reputable company that I can purchase an Evo III engine from. Was hoping that someone here could point me in the right direction.

 

If you're thinking of putting that in your 1G, you might run into fitting issues. As I read in the RRE site (Road Race Engineering, not the current RRM site). You would be able to fit the JDM EVO I-III 4G63 into the 2G with less trouble...

You might want to check the RRE site for that info as well as link for JDM engines...
