900 hp bmw m3 700 hp (at the flywheel) with the Garrett GT30/40. GT30/40 was more than enough at the beginning. Turbo system upgraded with a bigger ball bearing turbocharger. Nowadays a Garrett GT42/51R resides under the hood of the M3. With 30 psi of boost we made 900 hp and 772 lb/ft of torque at the flywheel. Engine: - BMW S50B32 block- Low compression forged pistons- Forged connnecting rods- Custom made connecting rod boltsCylinder Head: - Schrick inner valve springs- Schrick outer valve springs- Schrick titanium upper retainers- Schrick steel lower retainers- Custom made cylinder head studsTurbocharger:- Garrett GT42/51R (800-1,000 hp depending on the compressor wheel)- Ball bearing (the same model has a non ball bearing type)- Custom made water and oil piping- Custom made turbo flange- Custom made turbocharger connecting unit- 50 mm wastegateExhaust system:- Hand made exhaust manifold: The new exhaust manifold was manufatured in 8 weeks. Stainless steel was chosen for its durability. Pipes with different lengths and diameter were welded together. At the end there is a pipe network under the hood. To make installation and removal of the manifold easier for periodic servicing, flanges at various bends of the manifold is used. - Ceramic coating of the manifold- Wrapping of the manifold- Hand made dump pipe 110 mm- Hand made dump pipe flange- Removal of the catalytic converter- Removal of the resonators- 2 x 80 mm straight piping until the rear muffler- Hand made rear mufflerIntercooler:- 1000 hp air/air intercooler- Hand made intercooler piping- Water injection onto the intercoolerIntake Manifold- Custom made intake manifold: 18,000 cc (1,104 cid)- Cold air intake located at the rear of the left front fog light- BMC Formula 1 air filterFuel System:- 3 x Bosch Motorsport fuel pumps- Surge tank in the trunk- Rising rate fuel pressure regulator- 1,000 cc Delphi injectors- Modified fuel injector rail- Braided fuel lines
