B&G Custom Turbo
740/686-2897
www.bgturbokits.com

Kits Available:

  • '86-'93 5.0L
  • '94-'95 5.0L
  • '96-'04 4.6L Two-Valve
  • '96-'98 4.6L Four-Valve
  • '99-'04 4.6L Four-Valve
  • It may not look all that pretty in the supplied photo, but you can be darn sure that the B&G Custom Turbo kits are super nice-looking when done. B&G offers its Stage 1 and Stage 2 kits, with both kits coming with everything needed for installation, as well as being test-fitted on B&G's in-house chassis. No trimming is required with either kit, all accessories can be kept, and they will only work with hatchback engine mounts.

    B&G offers the same kit for both the Two-Valve and Four-Valve engines. The twin-turbo setup is a custom application (call B&G for more info), but the single-turbo deal is a bolt-in kit. It requires slight trimming of the inner bumper to clear the intercooler, and you'll need to pick up the needed front suspension components such as an aftermarket K-member and coilovers. The kit was test-fitted with both D&D and QA1 K-members. You'll also need to supply an upper hard line and fill neck, as well as an overflow tank.

    One more note: On '96-'98 cars, you must move the driver-side coil packs. When you call B&G, make sure you mention you read about all of its kits in this buyer's guide. You might have some money left over to buy lunch if you do!

    Kits Available:

  • '05-'09 4.6L Three-Valve
  • In collaboration with Exile Turbo Systems' Rick Head, Team Performance Products developed the Heritage GT twin-turbo kit for the '05-and-up Mustang GT. The kit uses a pair of Garrett GT2871R turbos to produce 470 hp in bolt-on form. For those wanting more power, the kit can be boosted with upgrades to make upward of 900 hp. The kit comes with everything needed to make it a true bolt-on system, while retaining use of the stock exhaust manifolds.

    Kits Available:

  • '05-'09 4.6L Three-Valve
  • Blow-By Racing's complete turbo system for the '05-and-up Mustang looks as nice as it performs. The kit is designed to produce 450 hp at a mere 7 psi of boost. While it's capable of kicking out 650-plus horsepower at 15 psi, Blow-By recommends getting the engine upgraded with pistons and rods, as well as having it tuned by a knowledgeable tuner. Based around a 61mm Garrett turbo, this is one kicking kit.

  • '05-'09 4.6L Three-Valve
  • Granatelli Motor Sports offers an intercooled single-turbo kit for the '05-up Mustang GT that has been seen to boost power by 157 hp at just 8 psi of boost. The system bolts on in about 10 hours, and showcases a 76mm Turbonetics turbo, a Tial wastegate, and everything needed for installation. As for the intercooled portion of this show, a pair of Spearco 221 intercooler cores help chill down the air charge before it enters the intake manifold.

    Kits Available:

  • '05-'09 4.6L Three-Valve
  • '05-'09 4.0L V-6
  • STS Turbo has a unique way of mounting its turbos. Instead of the tried-and-true underhood location, the turbos are located remotely in the rear of the car.

    STS has three turbo kits for '05-and-up Mustangs. For the Three-Valve-equipped Stangs, you have a choice of a single or a twin-turbo setup. The single-turbo kit is good for 400 hp at 6 psi of boost, while the twin-turbo setup can ring out 500 hp on low boost, 650 hp at higher boost levels, and 1,000 or more horsepower on a modified engine.

    STS also offers a kit for 4.0L V-6 cars. For now, the kit is only available in a single-turbo configuration, but expect horsepower figures to check out in the neighborhood of 250 at 5 psi of boost, and a V-8-slaying 313 hp at 9 psi of boost. Keep in mind, all of those horsepower numbers are dyno-proven on STS' dyno and measured at the rear wheels.
