Continuing on with my turbo project... Here are some pics of the head work that just got completed. I will post flow number as soon as I get them.

Enjoy the pics... Take a look at the older valves.. do they look deformed? lol

[ricerrx7]

That looks awesome! How much $ for everything?

[FordFasteRR]

omg you are so crazy .. lol

oversized valves AND porting ! LOL

Hopefully you'll make some power with boost !

If someone wanted to use this head on an NA motor they would need to advance the timing to burn up all the air/fuel mix better otherwise the power gains would be sucky + the mid-range torque would suffer due to slower port speed... (with a turbo all of that doesn't matter so you don't have to worry about timing advance).. if anything, you'll have to pull some timing out but that is easily done with an MSD box :)

WOW! :bowdown: How much $$ is going into this??

[Cypher]

all i have to say is wow... and when will we see this project actaully go into effect?!

like your car getting the turbo put on and such

[Estopatitiana]

so lets say we had a turbo charged beta2 with porting/bigger vavles and another without the big valves and porting (also turbo charged) how much of an advantage would the ported one have over the non?

[tharptroy]

how much for the valves?

also, oversized valves dont always equate to better flow (im sure you know this)

anyway, looks awesome.

I said it once and I'll say it again
WOW!! :bowdown:

[ricerrx7]

How much was it, and where did you get it done?

[swifty]

What size are the valves, and who makes them. Looks nice, I want one!!

[Kaborwildfire]

I have to give credit to Jeff over at CHR motorsports. I got my work done by them. They offer 1mm oversize valves from SI and REV. Here is the web addy.. www.chrracingproducts.com
Check em out , email them for prices. :)

[dmdicks]

Hmmm....I wonder where CHR is located.....hmmm.....I wonder where I had all of my head work done......hmmm......I wonder who had the first Hyundai Cylinder head worked on by Jeff......hmmm...... :)
