On3's LS1 Foxbody Swapped Kit / Build
At first I really didn’t give the LSx / Foxbody swap much thought and personally saved my black coupe from getting a GM engine swapped in. I thought it was a sin to put a GM engine into your Mustang. After looking over a few, seeing how well they run and how clean they install, I took on the newest foxbody turbo kit design. The project started with a local car friend’s coupe with a LS1 / T-56 swapped in and ready to design around. I couldn’t believe the room we had to work around with and made this a nice system and installs very clean. As much as I hate to say it, I would like to at some point build a clean coupe, stripped down with a 6.0l swapped.
The car has been 11.50 n/a so we have a good base line and will see where the car goes with boost(….9.999 lets hope). As far as the build goes, we have a set of custom tubular stainless steel headers that merge together in a similar design to our fox 5.0 system. The downpipe is also stainless and goes from 3” and transitions to 3.5 to the firewall. So that will support good power and not become a restriction like some of our other systems that just have a 3” option. This will fit any turbo up to the 7875 but I did fit a t4 flanged 88mm on the car to be sure it will clear. It will take a custom transition on the downpipe since the outlet of the turbo is larger but a pretty simple cut / weld if you needed the 88mm.
As far as the cold side goes, its all 3” aluminum tubing and bead rolled ends. All kits will come standard with the black couplers that you see and all stainless t-bolt clamps. We use the standard 25”x 12 On3 air to air intercooler and will have options for a 4” core if requested. Once again, this is all routed very clean and has a high polished finish that looks really trick.
The car we mocked up on did have a tubular kmember but we kept the factory unit it mind and will be a little tighter with the downpipe but will clear. We did not have a/c on the car so as of right now, we are going to advertise the setup as a/c must be removed. Power steering and power brakes were kept in place and no need to remove either.
All in all, this is the easiest kit we have to install, not sure how popular it will be but we shall see. I don’t like getting calls for kits and we have to tell customers to go elsewhere. So we are going to fulfill this market and excited to see what our customers will do with the new setup.
This is a production system so we plan on bringing the system in very limited quantities to market Jan 1st tentatively. We have started our pre-sales on the system as a lot have already heard and been waiting for the release. If you have any questions, feel free to ask about the project and the kit design.

I will try to keep updating the thread as we get further along with the car. The production has taken longer than planned as well so we are a little behind on everything. We still have a few parts off the car that we wanted to tweaked before production. Once that’s back together, numbers, videos and track times shouldn’t be too far behind

You guys have quite the assortment of turbo kits now for a variety of cars.
Crazy to think you did only mustangs with ford power not to long ago. Now you have gm trucks and car kits along with lsx swap kit now too.
Not too many companys doing a wide variety of bolt on kits like you are especially at the prices you offer.

You and me both! I have too many projects but working with the LS engine in these cars is just so easy. I love my built engine 4v swapped 90 coupe but its tight and difficult to work with. The LS has a clean install with very little wiring, simple to access anything and parts are all reasonable. Ill build one for sure, just dont know when
Thanks, my main focus was really the Mustang but I knew I was missing out by not branching out. I have ran the company myself for the last year and hired some good help this year. Thats really allowed myself to get into the back, start mocking up kit and working with cars more. Hope to keep expanding, looks like we have a C6 z06 coming in within 2 weeks. Im going to start building a system for the C6 cars next. See how that goes and most likely do the C5 next

Looks great Chad! Cant wait to sell and install one of these! Got a customer down here itching with a gto. Any thoughts on making a kit for them? I thought about making one for him but its pretty tight in there and really dont have the time.

Sounds good Ill make sure Adam or I let you know when they are ready. Just check with us right at the first of the year and we should be ready to go with them
I have a lot of people that ask about the gto and g8 cars. I have this year pretty well planned out with our projects but who know. I didnt plan on doing a few of the kit designs I did this year. So as of right now there is no plan but if I get someone local with a car that might want to bring it in to design around, Ill let you know

I guess a questions to people that do the swap, how many people just go with a tubular kmember?

Good when this kit is done, just start mocking up the twin kit....
With the 6.0 guys all leaning towards T6 framed turbos, Off the shelf kits are kinda out. But off the shelf T4 twin kits can make the same if not more without having to fab it all up yourself.

Yes hopefully picking the car up tomorrow and should be able to get cranking away on that design. Im sure it will be a fairly detailed and involved design process but hope to have the kit out 2014.

I made my own setup and wished the whole time I had an option to just buy a setup and bolt it on.
Biggest issue with the gto's is getting a decent dp down the firewall. 3 inch is the max really on the driver side. The pass side you need to remove or relocate abs to get anything larger than 3 inch past the valve cover/wires etc.
