What accessories are needed on the top end? I have a stock block w/ stock crank and forged rotating assembly (99' gt) shooting for 500-550hp (limited by cast crank obviously). Can I use my stock PI heads,cams,intake etc. with this kit?


Helpful (3)
  • If you have fully forged internals (aside from the crank) then the motor will handle up to 600rwhp comfortably. You can use your stock heads up to about 450-500. If you upgrade your heads with a set of stainless steel valves and brass valve guides along with stage 3-5 springs, you will be set up for success. You can use your stock cams and have no trouble what so ever. If you want to upgrade them that would be great to. But you can only go up to about a stage 2 turbo cam with notching your pistons. Stage 1 turbo cams would be a great upgrade without any problems. The stock intake will be alright but in my own opinion I would upgrade it to a typhoon intake or the edelbrock victor jr you will need to upgrade your fuel rails. BBK high flow fuel rails. When and if you get this kit, if you want to get all the power you can you need to upgrade to the SVT ford focus 255lph fuel pump and that will get you to where you want to be on HP. Of course you are going to need a Boost-a-pump. You will also need 42lb-60lb injectors. Any other questions just post them.

How much horsepower is the base tune putting out? What other accessories will i need to get around 500 hp out of this turbo?


Helpful (1)
  • Your pony came from the factory with right around 230rwhp. Unfortunately the 1999-2004 stock mustang interals will max out right around 450rwhp. To daily drive, 400rwhp is the max. After that you will be killing her quick. You will need upgraded internals, along with frame upgrades such as torque box plates, and ofcourse subframe connectors. This will ensure your 500hp monster modular motor doesnt twist your frame.As as side note, the stock 1999-2004 mustang block itself is good for 1000rwhp. Once your longblock is upgraded for boost, 500rwhp will be easily obtainable.

I have a 2002 Saleen S281 4.6L 2 valve, with 30k original miles. The car is n/a. No power adder. I'm thinking about adding a single turbo? How much horsepower will this motor hold in stock form? I'm hoping for around 500-600? Thanks.


Helpful (0)
  • Without adding a bigger fuel system and a transmission built to sustain the amount of power you are looking to accomplish, I would recommend keeping the HP rate around 420 as you will run the risk of blowing the motor. If you do add the aforementioned parts, you can always change the wastegate settings to max the HP around 700-850 depending on a custom tune.


Hi, would this work on my 3.7L V6 Mustang GT (2000)? Thanks


Helpful (0)
  • This turbo will only work with 4.6L Mustang GT's and not the 3.7L V6 Mustangs unfortunately.


What is a list of things i can do after installing turbo on a stock 99 GT to increase HP without blowing out the engine? to get somewhere around 500-550 HP throughout time. also what kind of transmission would be be good?


Helpful (0)
  • There is a long list of modifications that can be done after installing the Hellion Single Turbo - Complete Kit (96-04 GT). I would recommend sending us an email or giving us a call and one of our Mustang Experts can discuss with you some of those options along with a transmission for you to go with.


I have a 2005 F150, with the 4.6L 2v. Would it be fairly simple to modify this kit to work with my truck? I know the main difference between my motor and an '04 GT's is the intake and throttle body.

  • Hi, We can not guarantee fitment of this Hellion Single Turbo - Complete Kit on anything except the 96-04 Mustang GT i suggest speaking to a local performance shop that works with turbos they should be able to find you a set up for your F-150.
