I am thinking about porting and polishing my stock GSR Intake Manifold until i have a chance to buy a skunk2. I was wanting to know how much should i get it bored? I dont know to much about this stuff so any help would be appreaited.

Thanks in Advance

 

there is a lot of factors to determine the size of the bore. What do you plan on doing with the car? powerband location? etc.

 

are you doing it yourself or going to a shop?

 

why would you do that?

 

do not polish it...just port it

what about for FI? i could understand for an NA or not heavily modded car...sorta...

 

I am going to take it to a shop to have it done. I am wanting to do this just until i get my skunk2. I want to add a little more power. It will be naturally asiprated for now

 

your best bet is to not waste your money for the time being and just wait for your skunk2 to come.

 

Just wait for the Skunk2. I wouldn't fool around with the stock GSR intake manifold, but that's just me.

 

k cool, thx

 

I port matched mine myself. Just get an extra gasket and lightly tighten it down while you remove the material.
