Ported intake??

[jstang209]

Hey im in the process of buying a new block.. i was wondering if theres anything i can do to freshen up my stock upper and lower intake.. im kinda outta cash or i just would upgrade it.. but is there anywork that a machine could do to it?

you can get tmoss to port your stock lower..i plan on haveing that done sooner or later

 

[jstang209]

what about the upper.. theres nothing u can do to it?

 

[slow93]

it can be cut in half and ported all the way through like that but i dont have any clue as to where you could get it done

The upper isn't the restriciton in the stock intake. It's the lower intake that is the bottle neck.

Next problem would then be the stock heads...


Edit: Go here and read = TMOSS

Extrude Hone it. I dont know how much it costs though. Best thing to do is save for an after market one better in the long run

Im in the process of porting my lower intake im half done its going well just takes ALOT of time.. i post pics if wanted when im done. Theres nothing quite like the feeling of knowing your hard work will make more power

i called a local machin shop and they said they'll port the lower in about 3 hours.. 60 bucks an hour.. worth it?

I wouldn't do that, TMOSS charges just north of 100 bucks. I think 110, but I'm not sure. Plus he is THE person to go to for porting stock lowers. He's done so many and has so much experience I wouldn't even look anywhere else.

Thanks for the props guys.........and the pricing above is labor, shipping is ~$25-30 total.

the upper can be ported, but it does have to be cut open. I don't recommend it unless you have a VERY good reason for sticking with a stock intake (stealth racer). You can open the upper TB runner from 63mm to 65-67mm to run a 65mm TB. Porting the lower brings the stock intake into the 180-190cfm range, well above the 160cfm the stock heads flow and right about what stock GT40/GT40P heads flow. Both of those heads are a good application of a stock ported intake.

Extrude Hone is well over $500 for an intake - definately NOT worth it for a stock intake imho.
