I'll wait awhile for everyone to stop laughing.

Okay, as silly as it sounds, I'm curious if this engine responds well to intake and exhaust modifications (or are there bottle necks elsewhere that are going to limit this).

The stock intake looks pretty restrictive (1996 geo prizm), although it does look like it would get some pretty cold air. Has anyone tried to improve upon it?

Has anyone slapped a turbo on one of these?

i have tried to improve upon these things, milled head CAI and full header and exhaust. I don't have any dyno numbers ( mostly cause i'm cheap) but personally don't seem to see any differance. currently putting a turbo kit together, i'll let you know how it goes when we're done here

4afe with 20v bt pistons any info?
