This is one of the Original Turbo Kits that started the On3Performance Brand over 14 years ago!
We have tested and raced this turbo kit on countless Mustangs across the country. We’ve worked very hard to improve this kit over the years and make it into what it is today. Back when we originally were thinking about offering this kit, we were skeptical about this swap. We weren't sure if we liked to see the LS engines getting tossed into our beloved Foxbodys. After working on our first donor car, however, views changed fast and we got excited about the project. The LSX engine leaves a lot of room in the engine bay, making it a straightforward set-up to work on. With the power potential of the LS platform, this kit became an easy decision. They respond excellent to boost, have great longevity, and are reliable at fairly high HP.
For the kit itself, we followed the design of our already popular fox 5.0 system and placed the turbo in the same relative location. The headers are constructed of 304 stainless steel and made from thick wall 1 3/4" tubing. The On 3 Performance 3.5" stainless stepped downpipe will support basically whatever power you try to throw at it (Up to 1000hp~). The cold side is made from 3" 6061 aluminum, all bead rolled with a polished finish. 50mm BOV flange pre-welded onto intercooler piping.
Every system comes standard with our On 3 Performance 800hp bar and plate intercooler and we stock upgrades to our 1000hp 4" race core intercooler for $89. The couplers are all black, 5 ply, and only use stainless steel t-bolt clamps which are included. This will allow for the most clamping force around the tubing for a blow-proof seal. The On 3 LSX Foxbody turbo system is going to come standard with the 70mm journal bearing unit. This is a great intro turbo for those looking to keep around 600rwhp.
We have several Turbo Options available for power ranges from 500hp to 1000hp+. If you’re not sure which turbo would be best for your specific build, give us a call at the shop 614-439-0057, and we’ll help you out.
***Please note, we have been running into issues with customers attempting to run UPR and QA1 K members with the kit. Team Z and AJE and Maximum Motorsports fit without a problem along with the stock k member being in place even.
When running the Maximum Motorsports Kmember use:
Maximum Motorsports 4.6/Coyote/LS Swap frame with solid UPR adjustable "4.6 to LS” motor mounts. In the engine farthest forward adjustment slots.
