Porting an LS2 intake for Procharged motor Im getting ready to start my Procharged 408 motor build....Before anybody says junk the LS2 and use a FAST, IM NOT BUYING A FAST...MY build is on somewhat of a budget and I would rather sacrifice a few hp than spend that kind of money on another intake. I came across a new, never installed LS2 intake very cheap a while back. I want to try porting this intake myself. Does anyone have any suggestions for my first port job??? Also if I decide to not try it myself, who on this site offers a porting service, and what is the going rate??
Another question i have is what kind of o-rings do i need to run on my injectors? I still need to buy injectors and was wondering if I could just order ones that fit right..
Any info is appreciated....

Injectors come with the right O-rings.
For porting, I'd look around for details and do it myself. You'll end up with some new tools, new knowledge and the satisfaction of knowing exactly what was done to your baby.

Tony Mamo at AFR has more intake porting knowledge than anyone else that I know of, you might try giving Tony a call.
You can use the standard fuel injectors, and then use adaptors for them, but recently larger fuel injectors that swap right in for the LS2 have come out.
We sell these Bosch injectors http://www.exoticperformanceplus.com...html?item=1118 and I believe Accel or someone recently came out with some higher flow ones. Bob

For porting I use a Sears Flex-Shaft grinder, sort of a larger, heavy duty Dremel. And I actually use Dremel collets and abrasive wheels in the Sears tool - you can buy them in bulks of 25 rolls, large or small, in 3 different grits at Home Depot or OSH.
I also use an electric die grinder for heavier/fast work. That uses either commercial tools or Dremel heads with a simple collet change.
That and a nice face shield, a couple clamp-on work lights that you can move around (backlighting your work is a useful porting trick - point the light up the port from the rear), and WD-40 on metal. A little might be useful on plastic too.

porting would seem to be unneccessary with a procharger. the very little it would gain if any under boost could be made with ...more boost. my guess is the best port job in the world on an ls2 @10psi would be out flowed by a stock ls1 @12 psi. i would spend the money else where. belt slip is an issue with prochargers.

if that was completely true, everybody would run stock heads/intake/ and tb on all forced induction motors. If i port the intake myself, it won't cost any extra. Belt slip won't we an issue with the 8 rib setup and somebody that really knows what they are doing setting everything up.
ls2 is supposed to be better than ls6 so you should have me beat leaving it alone.

Here we go again LOL... Don't touch the intake manifold. Leave it be. Do a search for LS6 vs FAST and read the billion page thread about it. I doubt you'd see any HP gains on a dyno between the FAST and unported LS2. Don't gimme that "if that was completely true, everybody would run stock heads/intake/ and tb on all forced induction motors" either. Heads are completely different because they have better flowing EXHAUST ports- which is the key to FI motors. Since the air is being forced in regardless of how (un)restrictive your intake manifold is, getting the exhaust out of the cylinders becomes the more important issue.

If you already have the LS2 intake and TB great- use that. But don't port them. IF you got any gain at all out of porting, it would be minimal at best. Probably not even anymore gain than what a 2° ambient temperature gain would net you.
Port it,Take it appart and port the inside as well not just the runners
If anyone has felt the runners you know that just smoothing it out helps alot
The gains with porting in a FI is not as clear as in N/A but there is a gain
IMO Price vs Gains are not worth it to go with Fast,If you do your own porting that´s just free Hp
