Engine:
Based on a C20XE –88. Balanced and weight adjusted. Block O-ringed. Mahle forged low compression pistons, 9.0:1. ARP big end bolts. Balanced flywheel from Kadett Gsi 16v. 12-9 quality flywheel bolts. Ported coscast head. C20XE cams. CNC-modified inlet from Astra Gsi 16v. ETC throttle house removed and replaced with a CNC-machined supercharger-adapter in billet aluminium. Lysholm 1600 twin-screw supercharger. Charge pressure (at this moment) ~1 bar @ 7000 rpm. The supercharger has future capacity for a charge pressure of ~1,7 bar @ 7000 rpm. Single throttle house from Omega 2,6i. K&N air filter. Custom built intercooler for high efficiency and low pressure drop. HKS racing recirculating blow off valve. TWM fuel rail. Bosch low impedance fuel injectors, 580 cc @ 2,5 bar. Malpassi 1:1 regulator, 3,5 bar fuel pressure. Modified standard fuel tank. Twin Facett “Red Top” pre-fuel pumps. Pre-filters from Volvo 340. 3 litre catch tank. Bosch motorsport 044 main fuel pump. Audi K-jetronic main fuel filter. Calibra Turbo watercooler. 75 degrees thermostat. Saab 9-5 Aero oil cooler. MBE Systems 967 ECU (fuel & ignition). Distributor removed. Bosch direct ignition coil, double-fire type. NGK BCPR7ES spark plugs. Magnecor custom-made ignition leads (8 mm competition type). Bosch LSM-11 wide band lambda sensor. Lexmaul 4-2-1 system. 2,5” exhaust with Apple racing mufflers.
