 We have been selling this system now for 17 years now! Helping many builders to Turbocharge their Foxbodys cost-effectively. This is the very first kit we brought to market all the way back in 2007. It has been a great performing system, and has proven itself countless times over the years. Whether you are running a stock 5.0 block looking to make a fun street car, or you're looking to go 8's in the quater mile, this kit can get it done! Most of our customers end up in the 400-500whp range, a car in this power range has the potential of being in the 10's and a pretty serious street car with good manners. We have said this since day one and have put together what we think is the best horsepower per dollar modification you can do to your car. You can literally bolt this kit on and double the factory horsepower(Close to TRIPLE the torque). Most stock 5.0 motors will put down around 185 +/- rear wheel horsepower. The great thing about going with a turbo on your foxbody, you can dial the boost in according and have serious room to grow. Adjusting boost is as simple as turning the knob on the included boost controller. Turbo Option Help: Our On 3 70mm included is a good turbo up to the 500~ rwhp range. Beyond that, we would then recommend either our On 3 76mm journal or ceramic ball bearing option(650-700rwhp max). If you have the supporting mods and plan to be in the 600-800rwhp range, your best option will be our On 3 7875.  

***** WE ARE EMAILED ON A DAILY BASIS ASKING IF P-HEADS ARE GOING TO BE A PROBLEM, THE ANSWER IS NO. YOU CAN RUN THE P HEADS WITH YOUR TURBO SYSTEM AND ITS NOT A PROBLEM. MOST PEOPLE COMMENT THAT THEY RUN A 90 DEGREE SPARK PLUG BOOT AND OTHER THAN THAT, YOUR GOOD TO GO ******

  YOU NOW CAN RETAIN YOUR AIR CONDITIONING We have made a few changes as well to our setup and although its tight, you can retain your A/C. It will involve you just tweaking the lines slightly coming out of the condenser with your hands. Then normally we will use a few wire ties to secure the lines all in place so we know they cannot come in contact with any of the hot parts. On the streets, our shop car is an absolute animal with the On3 70mm kit installed. We are running 275/60/15 M/T drag radials on the car and it will blitz them 1-3 gear on the street with 7psi. As far as street drivability goes, it doesn't change for the most part till you tip into the throttle. We did run it with just the open downpipe so it was loud, other than that the car ran and drove the same as it did before the install. With our turbo system installed you will retain the power steering but in order to fit the turbo and downpipe, the kit doesn't make room for the Smog pump. So this kit is required to be used for off-road applications only. The On 3 Performance 5.0 turbo system includes all the components to get your turbo kit on your car and ready to get it back up and running. As you will see from our photos, this kit bolts on to your car and was actually designed and tested by us so we know the kit and we know it works. There is not another turbo company on the market that has a kit near our price, proven and come as complete as our system does.

What do I need in order to finish off my build and what should I add?

In order to finish off a full turbo kit installed, you are going to consider the following options from us. This would be a typical 500 or less HP build and exactly what we would pull to do the install here. Clearly the turbo option is your call but the 5.0 foxbody responds great with the 67mm Premium Ceramic Ball Bearing Option:

 ** Our system IS NOT designed for HIGH PORT Heads or TWISTED WEDGE Heads **

As you can see from our list of parts included in this kit, it is just about all the hard components that you need to install the single turbo kit on your car. A lot of people email to find out what in addition to the kit they will need to finish off the kit. We offer a calibrated PMAS HPX Slot sensor, our CNC machined MAF flange and wiring pigtail so the MAF is just plug and play, On 3's new 320lph fuel pump (safe for e-85) with install kit, as well as the oil filter relocation kit for $95. Have us pre-weld your maf flange so its a bolt in when you get it out of the box, $60 tig service

BLOW THROUGH CARB GUYS, READ!!! ******

We have a good amount of customers that are running blow-through carb applications and making killer power. Some of our fastest fox customers are on carb applications so we can certainly help you. Most guys first off ask for a discount to leave out the items needed for fuel injection applications. There is not any discounts available, none of the efi items needed are included standard. Then the next most asked question is what all is needed? Well it's pretty simple, you're going to need your carb and then the bonnet to bolt on top that would take it to a 3" inlet. Most people will mock up the tubing and see how far it needs to go to connect to their specific application and just order a silicone coupler to length. There are a lot of places that offer longer lengths that you can just simply cut to desired measurements and use. There really isn't too much to the blow through applications
