I was thinking of switching out my stocker for a new one but i'm unsure which one to go with. Considering my mods below would you guys suggest it and if so which one should I go with?

 

Keep the stock one.

 

Are you going with a bigger intake? If not, what's the point of the new t-body?

 

Ya I would like to go with the 90mm setup in the future but i'm thinking maybe I should just do that all at once.

 

Don't waste your time with buying a bigger one, just Port & Polish your factory one. It's really esay to do. Do you have a Dremel with a drum sander attachment?
What I did was buy a new take off tb from Ebay & P&P that one. On the inside of it, it's kinda a rough cast that needs to be smoothed out and make it almost a mirror like finish,as well as it has some ridges in front of & behind the blade that need to be sanded down. If you want to go trick, knife edge the blade.

Where this how to says to fill in the hole with putty, body fillr or epoxy, I just stuck a pencile in there(to keep the hole) and filled it in with that quick metal stuff that's a 2 part system where you mix both parts together & it hardens. It's kind like JB Weld

 

If you went to a TBSS intake, or a FAST 90, then would be the time to upgrade. Otherwise, leave it be.

 

So I filled in the gap on my spare throttle body and polished it. Was their any certain size that the holes are supposed to be? Is their an easy way to knife edge it? What about my mass air sensor. Is their any way to get more flow from it?

 

Anybody?

 

Don't mess with the MAF, most guys cause more harm than good when they descreen them, and the aftermarket MAF's are also problematic.
