Modding Advice??? I have a '98 WS6. I am going to start purchasing some of the 'regular' bolt ons, along with a cam. Right now, I have shortie headers with no cats, and Borla exhaust. I just recently installed a new RAM HD clutch, pressure plate, along with a new stock flywheel. For whatever it is worth, I also have a WS6Store short shifter, with a HURST T-Handle, with roll control.
My question is mainly about the FAST intakes. I have seen the ones for a 78MM throttle body and for a 90MM throttle body. At some point, I will be changing the cam and possibly heads. Should I go with a 90MM throttle body and intake?
I know that there is no 'right' way or 'best' part. However, I would like to make educated decisions when purchasing my performance parts.
Thanks in advance for the advice!!

The FAST 90/90 is a bit overkill for a NON h/c motor, but would be more of a benifit once you DO add the H/C... The FAST intake make about (I think) 10 more HP over the stock LS6. I am not sure on what basis and mods they were comparing the manifolds on. You'd be sacrifising some HP until you get the H/C... if you were to do the FAST 90/90 before the H/C.
I have heard that the FAST 90/90 really shines when you Stroke/h/c...
I'd just do the LS6 for now... it'll be good for a while..

Check EBAY for the LS6 Intake. Most of the parts vendors sell them too. Check on the main page w/ the list of vendors on the right.

Check www.Installuniversity.com They might have some info on it. You could also do the bump stop mod while you got that dremel and TB in your hand. -You'll need a multimeter for that, tho.

IF you are going to get H/C eventually then why waste the extra money on an LS6 intake? I am going to get the FAST 90/90 before i get h/c only cause i know ill be getting h/c eventually and i dont want to waste any money on something i know ill just replace later... just my opinion. You wont lose THAT much hp if anything with the 90/90.

FAST 90 with a NW or PTM TB (FAST 90mm TB is junk). This will easily out perform a LS6 intake by 15-25rwhp on a cammed or h/c/ setup. If you are serious about getting a cam or more, then I personally wouldn't waste money on buying a LS6 first. People who tell you different are generally trying to cover up because they didn't get a 90/90 setup.
Fair do a FAST 90 will only see minimal gains over a LS6 on a stock motor because a FAST 90 will show its abilities above 5500rpm and a stock motor is out of puff by 6000rpm.
But you won't loose anything by going FAST 90 it will just cost you double.
