Man I don't know if I am just not looking in the right place or if I'm not looking hard enough but it sure does seem like I can't find anything for our cars... I have looked through jegs and summit but found nothing... Do you guys know where to look ?:th_scratchhead:
 


Hogan Performance does Downpipes
Doug Thorley is for Headers
Car Tuning makes a Turbo Kit
There are intakes out there...google it.
Magnaflow, SLP make catbacks
HP Tuners for tuning...
 
thats cuz there is nothing for the ls4. just a ****ty lookin k&n. your best bet is to get ahold of an intake from an ls6. thats the best thing you can really do for it right now besides exhaust

well on basic stuff i mean.. im not saying there isnt anything. but just not as much stuff as the 3.8s have in the aftermarket

Maybe not...but you can basically use ANYTHING LS related for the top end if your willing to do some work...so there is tons of potential.
 






I have done most of the math and a chip ,cold air intake, exhaust, and a tune and I will bee real close...money is not that big of issue.. I just don't want to do anything yet that will affect the drivetrain warranty...
 
^^THIS...for sure. A local had a 1.8 rocker/75 shot GXP with exhaust work and his transmission HATED him.

To the OP...a LS4 with a custom tune, headwork, Doug Thorley Headers, LS6 Intake, K&N CAI, Custom Catback, Poly Mounts, and D.O.D. deleted with a LS6 cam...made around 320 to the wheels...so even being MEAN and taking a 20% drivetrain loss that's only 380-ish to the crank. 400 HP is going to difficult without the bottle or boost. Which is why I'd be interested in your "math" and how you got there....since LS4 cars are "rated" at 303 horse...but most make around 250-260 to the wheels and a little more torque...I don't see how your even at 280 to the wheels...

07 GT's still go for 17-18K around here.

GXP's are more.

CT turbo kit isn't expensive compared to cost of car.

It'll get expensive when you blow the living god out of the transmission...so I always say...when you buy a turbo kit...expect another 2G's on top of that when your transmission takes a dive off the shallow end head first.
