About to Do a Sc Build.

I've got an 06 ls with 130k. I really want to SC the car. I've got a catback but that's it. Ill probably need a clutch what else besides the kit? What should I worry about with boosting at this mileage?

As good a place to start as any. A general multi-point vehicle inspection wouldn't hurt either.

I'd check engine as mentioned then contact mongorat on CSS he sells the kits for right around 1k. You'll also need a clutch and a tune and I recommend the rotated trany mounts and some sort of better CABS since yours will get destroyed with the added power if their not already destroyed.

First things first, what power are you wanting to gain?

I would do a compression test, then do a leak down test out your valves and crankcase itself. Next, you will need to upgrade your pistons, connecting rods, crankshaft, bearings, and fuel system. I know ZZP offers a supercharger kit for the LS, but you will need to have these mentioned above out of forged metals, cast iron will not hold down the increased pressures of forced induction. The reason why I am urging to upgrade your internals first, MP81 on this forum had an LS Supercharged Eaton M62 kit, connecting rods and bearings were giving him rod knock after 8k mileage.

Next, you will need to upgrade your braking efficiency to slow down the increased power, its not vital, but its important to slow you down. I would also upgrade your drivetrain (axles are vital) to lay the correct torque down to the wheels, or you will be rebuilding them roughly twice a year. Also to add, upgrade your fuel system consists of 43lb injectors, drain the entire fuel system for 91/93 octane, which will be required for forced induction/high compression engines.

I would also upgrade your transmission, if its an automatic, you should be ok, but a manual will require a stronger clutch disc for power on/off through the input shaft.
You can also upgrade wheels/tires to lay it down if you are still rolling stocks, I would also upgrade your suspension for traveling with a full FE5 strut/spring combo.


This maybe to get very expensive, but the technician/mechanic gurus will not argue against this setup. You most likely would save more money selling your LS and buying an SS.

I was just going run stock pulley. Not doing anything extreme. Just looking for more fun.

You don't need to build your motor to run a stock pulley but your motor could blow if you beat the piss out of it

12psi max on stock internals for a 2.2 from what I read, which should be fine for a SC build, as ZZP claims the M62 with a 3.4'' pulley should produce about 9psi. As Banker said, better you don't beat it more than you should and it'll hold together. If you want reliability, go with what 5t3alth mentioned, just be sure your bank account is deep enough before you start.

As stated you don't really need to upgrade the brakes, engine or driveshafts. Highly recommend the CABs though since their more than likely already shot. Make sure the engine is in good health to start with and you can go from there.

Someone has a kit listed for 1k + shipping on CSS BTW.
