The hot charge air out of the turbocharger is cooled by a custom A'PEXi chiller.
To prevent any cylinder scaring from forged pistons, the block was resleeved with ductile iron units. A set of 8.0:1 low-compression JE forged slugs replaced the factory high-compression cast units. JE forged pistons are stronger and are capable of withstanding the high temperatures and high cylinder pressures commonly found in boosted engines. Swinging the forged slugs on a micropolished factory crank are Crower con-rods. The Crower rods are substantially thicker and stronger than the stockers and are able to withstand the rigors of a pressurized engine that is capable of revving to 10,000 rpm. With the parts chosen for the bottom-end, the whole rotating assembly was sent out for balancing. Rafael then blueprinted the entire engine and assembled it with brand-new OEM bearings and seals.
Up top, drt modified the cylinder head by porting and polishing the piece to its racing specifications. After the porting and polishing, the head was resurfaced and a five-angle valve job was performed on the valve seats. The stock valvetrain was enhanced with high-performance components. Stainless-steel valves and high-tension valve springs now reside in the factory location and valvetrain orchestration is conducted by a pair of drt-spec racing camshafts. Sealing in the boost are stock head bolts with an SCE copper head gasket sandwiched between the head and block.
In charge of collecting the spent gases to feed the Turbonetics hairdryer is a JBE Racing tubular exhaust manifold. The Turbonetics T76 compressor is regulated to 23 psi of boost pressure by an HKS GT-spec wastegate and A'PEXi AVC-D boost controller. Exhaust fumes from the turbocharger are evacuated by a 3-inch downpipe and a custom system featuring an A'PEXi N1 canister.
The pressurized air from the turbo is fed through 3-inch I/C piping to a custom-fabricated drt front-mount air-to-air intercooler that utilizes an A'PEXi core. Chilled charge air is then forced through a 65mm throttle body mounted on a custom drt racing sheetmetal intake. Feeding the four 96-lb. injectors a heavy supply of high-octane juice is a drt racing fuel rail and Paxton pump and regulator. Igniting the compressed air/fuel is accomplished using the tried-and-true MSD 7AL-2 and Blaster HVC coil. Transferring the spark energy to the NGK spark plugs are a set of MSD 8.5mm Super Conductor wires. For engine management chores, an Accel Digital Fuel Injection computer was utilized. The technicians at drt meticulously tuned the DFI and were able to extract 593 hp to the wheels on the Rampage Motorsports Dynojet.
