Our LSA Stage 3 Max Effort SBE package is for those looking to have an even more advanced way to greatly improve their cars performance, up to 900whp.
This kit has several options, so please review them all prior to purchase. Options Include upper pulley & lower pulley, camshaft, fuel, cooling, intake & exhaust, Supercharger Porting, Head Porting, and cylinder head replacement.
For optimal performance & safety, all modifications listed will be necessary for our stage 3 upgrade. The only reason there are options that can be set to "Not needed" is due to some items already being owned by some buyers who have previously purchased these parts, such as with our Stage 1 & Stage 2 packages.
We highly suggest that you perform all of the cooling modifications that we have listed out. For the CTS-V Lid mod & Brick reinforcement you will have to ship us over your lid and brick. We generally have modified lids with reinforced bricks in stock ready to go and will ship a set of ours to you as soon as your units arrive and are inspected.
Camshaft selection: we always recommend a custom grind camshaft that we design specifically to your exact setup over any "shelf" camshaft.
Exhaust system options: The OEM exhaust & mufflers work great, the only requirement here is at least a minimum of aftermarket headers. We recommend headers with 2" primaries, over the smaller options.
Supercharger and cylinder head porting will require you to ship us your supercharger and cylinder heads.
