On3 Performance 4th Gen GM F-Body T6 Complete Single Turbo System Race
System 80 – 86mm - T6-Fbody-1
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
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.
Need Help Choosing The Proper Turbo?
If you do not know what you are doing with turbo sizing,
call in for advice. We do not want to see you ruin your turbo from lack of
proper understanding about motor cubic inch size and turbo exhaust wheel
sizing. We most commonly see this when our customers try to put a 65
exhaust wheel on a 6.0 or larger motor. The rule of thumb is the larger the
motor, the larger the exhaust wheel you are going to need. If you put too
small of a turbo on too large of a motor, the turbo will fail due to this.
Again, if you have questions, please call. We can’t possibly know what your
project/swap is if you order the kit off of the website without reaching
out to us first.
