i'm planning on buying a skunk2 intake manifold and throttle body this weekend and on the skunk2 site it says the manifold has a66mm throttle body opening and can be ported up to 75mm. so would it benefit me to get the 70mm throttle body and have it ported to 70mm? thanks

 

What is your setup?

 

just random bolt ons mostly. i might be upgrading my valve train with higher compression valves. i'm mostly in the process currently of adding mods to it

 

I would leave out the S2 manifold, but a bigger TB isn't a bad thing. There are better quality options for TBs than Skunk2 also...

 

ya... but i'm going for cheaper stuff... 12 bucks an hour doesn't get you very far lol

 

if you're going cheap on the TB,

ya i'm not that cheap

 

bore out the Manifold so it matches up with your throttle body. I used a dremel, then super super super fine grit sandpaper, then a LOT of compressed air.

 

k thanks. that's what i needed to know
