Anyone have pics for ported upper plenum?

I am taking my upper plenum off to port & match to my existing SLP runners and to the bigger throttle body that I just bought. I know I should just match up the ports, but internally is there anything that I could knock out?

Here are mine, I just finished them. I knocked down the front walls in front of the EGR ports and blended the sides. I used a dremel, it took a while and I'm just getting the feeling back into my hand

Do it yourself!

Long as u have a die grinder, electric or air, its super fast and easy to do.

I hate using Dremels for it, but it will work, just gonna take ya longer.

A decent set of bits for alum should run you $40-60 and should last for many port jobs.

Just think, next time u pull your case, you can port that too :-)

later
