First, Let me say that I still need tuning and all that poop. I am going to buy an LS6 Intake with 28.8 Injectors and a TB soon. What is the best way to go? FAST TB or BBK TB or do I just send my stock one in to have it Ported? Where at?

Here is another question. At the start of everyday, my cars Fuel Pressure is at 61 PSI and after I come home "HOT & TIRED" The cars Fuel Pressure is at 48/49 PSI. Is there something wrong with my new Walbro 255lph fuel pump or do they do that when it gets hot? I should change the Fuel filter but I dont think its the cause.

Any Ideas? Maybe the Gauge is getting stupid?

 

Wait and see how the ls2 intake works seems better then ls6,haven"t heard too much about the BBK yet,I don"t know about the TB?

 

the ls2 intake may be better than the ls6, but it might not be worth the price difference to you.

unless you're going to run a fast intake setup, ie fast lsx intake manifold/fast tb, then just send your stocker to jantzer or bauer to get it ported, both are sponsers here.

all i know is that after i installed my walbro intank, my fuel guages started actin real funny. car got totalled shortly thereafter so don't have any resolution info, wish i did.

 

Why bother w/ a FAST setup when you're not running a huge cam and open headers? Save your money, and get a regular LS6 intake manifold, or do like the guy says, and wait till the LS2 intake comes out. From what I've seen of that intake manifold though, I've not been super impressed. Looked to have quality issues.

 

Yeah the LS6 Intake is my only option. What all do they do to Port the TB? I see some being 78 MM, 80 MM and 90MM.

 

Well that is very strange, and since I don't want to be rude, I won't ask. If you're doing the Intake only, than only go w/ the 78MM. Anything larger, and you've got problems making everything else fit. Plus, until you're running a mucho cam + heads + exhaust, the 90mm would just be too much. Good luck whichever way you decide to go. If money were no option, I'd go w/ a F.A.S.T. too though.
