98-02 LS1 Fbody On 3 Performance T6 Complete Single Turbo System Race System 80 – 86mm


Model Number: LS1FbodyRace8086m
On 3 Performance

We are proud to announce that we have designed a new T6 turbo system for the 1998 – 2002 F-body LS1 cars. This kit in particular is designed to be used with the stock k-member and will require the removal of the A/C. There is no way to keep the A/C using this system as we know customers will ask. However, check our other page if you wanted to keep A/C we have a t4 kit as designed that will retain A/C but will require you to use our turbo k-member.

Our T6 LS1 turbo system is one of the most complete kits on the market today for these cars. You will not have to track down manifolds from trucks, turbo from another place and make exhaust. We have a complete system to offer with many options so that you can get about all you need to install from one shop if you want. Our kit comes with everything you need on the hot side from manifolds to your turbo. The y-pipe we built off each manifold is 2.5” and merges on the passenger side. Each kit will include our On 3 Performance 80mm billet wheel turbocharger. (Below we will have the option to upgrade to our 86mm billet wheel unit as well)

Coming out of the turbo, we supply you a 2 piece downpipe that starts as a Marmon flange of the back of the housing routes through the existing hole underneath where your battery used to be. That will then go to a 4” v-band flange; from there we give you a small 4” section for you to run out the front bumper area. It does have an o2 bung for your wideband already welded in. This kit is sold as a bumper exit option only.

Moving on to the cold side of the kit, we have built this kit using 3” charge pipes for all of the intercooler tubing. Each kit comes with our horizontal flow 4” On 3 Performance bar and plate intercooler. We also have a 5” and 6” core that is available as well and listed under our optional items if you plan on making 1000+ going for higher boost levels. Our 5 ply On 3 Performance silicone couplers connect each intercooler pipe together and t-bolt clamps ensure maximum clamping force to prevent any intercooler pipes from blowing. Each pipe is bead rolled on both ends to add extra protection from losing a pipe under boost. All intercooler piping is made from 6061 aluminum to help dissipate heat and also keep weight down over using stainless. Lastly, our kit is designed without a MAF provision; most all builds we see go speed density for tuning so if you plan on running a MAF, you will need to adapt that on your own.

This kit will require you to stand up the radiator. This will be an option below as well as we have designed a stand up radiator kit specifically for these cars as well.
