I’m Looking For Body Kits, Euro Lights, Dash Kits, Turbos, And Everything Else Thank You!

And what if u would to supercharge the si as oppose to upgrading the turbo on the GTI?

I have a 1992 eclipse, non turbo 2.0
I was wondering two things:
1) Are there any perfromance computers or anything that will make my car a little faster ? I know honda has hondata, i didnt know if there was something similar to an eclipse
2)Will a galant engine bolt up to an eclipse ?

I have a 95 firebird and I am looking for a Superchip for the v6 mainly and I would also like a supercharger or Turbo Kit for it but I can’t find any of them or at least any that seem reliable, I have found lots of home made ones and I don’t want those. If you have any suggestions or links could you please tell me. Also if you have the best way to bring my car to 400 hp then I might just forget the turbos.
