looking at this pic is it okay to remove so much material behind the TB. It looks as though theres holes created, does anyone know if this affects anything? I read somthing about it affecting the egr valve!

 

anybody know anything on this?

 

You might have better luck on posting this on the TPI board. I've seen several threads on the TPI board concerning porting the TPI, but since I'm no expert I will only suggest posting on that board.

Good luck.

 

92 Formula, what color is your car? I can't tell if its black or green. In your sig pic, it almost looks like the same color of green as the 92 Heritage edition camaros. Do you have any more pics?

 

Hi Ward,

The Formula is Dark Green Metallic, original paint still. The only other pics I have is in the Reader's Rides. I was going to change it to dark red metallic like my old '91 RS was, but I think I will keep it this color.

Thanks.

 

those holes are for the egr they are there already, there is a wall about 1/4 maybe more in front of them, and on the side. u need to remove the walls , u will definitely have better luck posting this on the tpi board, actually just do a search u should be able to find everything u need to know.
