Porting LS6 Intake
Porting LS6 Intake Is it worth it?
Here's the situation. I work at an aerospace machining company and there are tons of machines here. One of the guys here suggested that I should port the LS6 intake. He would do it for me.
How far can i port it if so? And any suggestions? Precautions?
AND I just found out we have a sand blaster! COOL! One of the guys is sand-blasting my new ported Throttle Body as we speak!

Yeah, this is all I was told could be done too. no real porting, just matching up the runners. TPIS can do a 90mm LS6 though. They are a sponsor on here.

is it worth it? trade in my LS6 for $500? and pay the difference? i originally payed $275. The FAST 90MM is $800+
So 275 + 350 = $625 which is cheaper

so I cant just install the LS6 90MM intake manifold without tuning? i plan on getting a nice cam. some suggested a 224 which i heard is the biggest smog legal cam.
i will end up getting a 90MM throttle body aswell. any suggestions?? and will i have to tune if i only have the ls6 90mm and a 90mm TB?

LS6 flows better than the LS2.

tune or not to tune
im just being cautious cause if you think about it im going to be getting aton more air in there and there probably wont be enough fuel being fed so i might burn valves or sumthing..
LS6 does indeed flow better. There's been numerous real world tests that proove it too. I just did a quick search and found this test, there's others out there...

My source is a book... "Dyno-Proven GM LS1 Thru LS7 Performance Parts," not to mention the countless "online" sources like the one posted above ^^^ (thanks 95 Z28). ...and the fact that it's been discussed here on LS1Tech on several occasions (search)!
Overall, just because the LS2 has a 90mm snout - doesn't necessarily make it a better intake (e.g. take into account the plenums and runners).
Stock for stock, LS2 vs LS6 - the LS6 wins any day IMO.
Now porting them both and testing them, I've got no idea.
However, from what I hear, you can't really "port" an LS6 intake all that much.
In regards to opening the snout of a LS6 intake to 90mm, I don't think the gains are worth it.
...But if you're gonna pay someone to do the port work or open the snout - why not just splurge for a FAST 92mm?!
Ultimately, 1_bad_TA suggested a LS2 intake over a LS6 intake... and I'd say that would be a waste of money.
Just my $0.02! Hope this helps.
