winter project. H/C/I/N...question Hey guys i've been searching and readin up around here to see what proven combos are working for people. But i have a specific question for my set up. I just layed out a plan that i'm going to get workin on this winter. Intake, cam, heads, nitrous.
I plan a cam around the size of the MS3 and i'll find a set of used heads from someone to put on also. In which case i need to switch out my stock ls1 intake. Now... assuming i have a MS3 and heads, will an ls6 intake flow enough for that? Or do i need to move up to the fast? I hear most people say with big cams or head/cam you need a fast. It's just so damn expensive but if you guys say i REALLY won't get the best out of the setup with the ls6 i'll go with a fast. All these parts will be going on at the same time this winter so i want to have this whole setup chosen before i start.
If it makes a difference i will be running nitrous after the setup is complete.

humm, a big project eh?
Well, the FAST 92mm is never needed. A lot of plp are having great results with the LS6. BUT, if youre going with a MS3 sized cam and a nice set of ported heads, the FAST will show very nice gains for sure. If you have 1200$ in hands for the FAST, do it. The LS6 will get the jobs done though.
Youre looking at 420-440rwhp with MS3/ported heads with the LS6 and add 15-25 for the FAST. A good advice:go visit the dyno section and internal/external gen III for a while...a lot of research is ahead!!
Dont forget youll need that tune and gears if you want to be in the rpm you want..
Why not the MS4 ?

You know what, right as you said that, my buddy told me he has a MS4 for sale. MS4 it is. And i have a tuner lined up who did BESstrokednova on here. He's a good tuner so i'm ok with that. And as far as the gears, I'll be slow for a little bit 
till i can afford a whole new rear. And yes i know not to dig race with the stock rear with this set up. lol
It was really the intake question that i was only concerned with at this point. So if i come across a crackhead good deal for the fast i'll probably pick it up, if not i might port an ls6 i guess...But thanks for the info!

funny about the MS4...
I'm asking myself about the FAST too, but I think i'll go with a bigger cam first.
Dont forget to look at heads that will clear the MS4 or you will be forced to notch. Stock sized valves will clear in unmilled LS6 heads, I think.

do a vic jr and a nitrous outlet elbow...fits under the hood with any size inlet you want and with a 92mm TB...it will be cheaper than the FAST....Just a thought
