Question whats left other then heads/cam??

ok so i have a 98 M6 LS1 whats next for performance other then heads and a cam she has 103k miles.

MSD wires, NGK plugs
SLP lid, SLP smooth bellow, SLP cold air kit, P&P TB by Me
SLP LM1 catback, SS LT, Jet Hot Y(with custom dynomax cats i put in)
255 M/T ET Street on Salad Shooter (for the track)
UMI PHB, Relocation brackets
no tune yet, but im getting one in a month.

so what mods are left
LS6 intake
Electric waterpump
Spray(safe with 103k miles????)

is that it? and are they worth it? how much hp can i gain?

Thanks in advance!

pick up an underdrive pulley, a LS6 intake, 4.11s, and a good clutch. Work on the suspension as well because horsepower is useless if you can't get it to the ground

Definitely subframes!!! You won't realize how twisted our frames get without them, until you experience it first hand on your car. LCA, PHB, Koni's, should make the ride feel much better and steadier on the road.

Other than that, Fast 90 NW 90 like I just got.

i just installed 4.11 gears in my car and i have to say for the money its prob been the best bang for the buck yet. i have been pretty hard on mine and have had no issues at all with my 10 bolt (knocks on wood).i say get some gears and enjoy. if u plain on making more power its just a matter of time before u lose the 10 bolt anyways

TQ arm (adjustible)- Better launch, consistancy

U/D pulley- about 10 hp, no loss in driveability or ablilty to charge the battery.

90/90 ported- at least 20 hp over stock, maybe more.

4.10's- I found on my stockish T/A with suspension (TQ arm, LCA w/ relocation backets, Pan Hard rod), rolling on M/T ET Street Radials, and 3.42's I couldnt get the car to spin, all it did was bog, even off a 5.5k rpm dump. With Line Lock the 4.10's are perfect, I should be able to cut 1.7's with not a whole lot done.

SFC's are def worth it, with your Milage you should notice a big diff.

Get an LS6 intake and then a few suspension mods after that save for a cam and spray.
