Upgrade Questions

**[email protected]** · 02-08-2008, 08:51 AM

I have a 1999 M6 WS6. LS6 Heads, Cam, Intake, SLP Lid, pacesetter headers and corsa exahust, custom tune, Ported LS6 Oil pump,

What are some possible upgrades? I was thinking on going with Stage 2.5 heads and a bigger cam, Would i have to upgrade anything else along with this?

how about a LS6 intake or a FAST 90/90

springs and push rods, timing chain, stall.

Pretty sure the heads come with titainium springs, and I have an LS2 timing chain, sorry forgot to mention, and aren't stalls just for autos?

They shoudl come with springs as long as your are getting a assembled set. I would make sure that you get the right springs for your cam choice, otherwise you might have to buy different springs.

I don't think the heads you are getting has titanium springs, but it most likely does have titanium retainers and locks.

Otherwise you should be ready to go as long as you get a tune after the new cam is installed.

Ok Sweet, How much HP increase should i have by than and what size cam should I get? I dont want too huge where it's sluggish as hell, I dont wanna COMPLETELY take the driveability outt of it, cuz right now wit the LS6 heads and cam it drives perfect and isn't even hard on gas.

So, say Stage 2.5 Heads, Cam unknown, SLP LS6 intake, SLP Lid, Pacesetter Headers, Corsa Exhaust, Custom tune...What am i lookin at?

depends on what size cam you get..........sorry about posting about a stall, I didnt realize you were M6. I would say if you got a cam similar to TSP228R you would be around 405-415rwhp. Now if you upgraded to a FAST 90/90 you should pick up an additional 20-25rwhp.
