That's a neat project and a pretty cool car. Too bad they get such a bad wrap just for being a Hyundai and Korean and all.

Man, I'd probably cry if that car ran me. It probably would too! What's it weigh?

What numbers did you have previously and what are you shooting for in this new setup?

I'd like to know the specs for that car and you're new expectations for when it's done. I smell a trend...

on the dyno, i was pushing 242.0hp at 15psi with ALL stock internals except for the head spacer I used to lower my compression. My car stock was doing 118hp so you can see a huge leap in power.

The difference with this setup now is this:

FORGED Pistons
Completely Ported and Polished head, including polished valves, ported intake, and ported exhaust (both oversized and gasket matched).

With this, i know a person who ported there head on the tiburon (same specs as mine) and gained over 35-40hp alone with the port job. I spent over 900US dollars on the porting/polishing because i was looking for a quality job on the head.

Sorry, but I found this funny.





Seriously, that sounds like an awesome set-up,
just shy of 300 or so?
