Turbo Gemini 1.8L coupe - Gem Racing
Arthur's Holden Gemini runs into the tens on street radials at Heathcote. The car is powered by a Gem Racing Isuzu G180 1.8-litre 4-cylinder equipped with a Garrett GT35R turbo @ 32psi Boost and MicroTech E85 fuel system. Driveline modifications include a ProMatic Trimatic automatic transmission, 6500rpm stall converter and modified Gemini diff with 28-spline axles and full spool centre.

240sx/180sx/240sx s13 silvia The 1.8 L CA18DET was the last version of the CA engine to be released. It produces 167 hp (124 kW) and 166 lb·ft (228 Nm). It received a brand new DOHC aluminum head with 16 valves. The turbocharger was also upgraded to a Garrett T25 (.48 A/R) unit for increased flow capacity, and as such, was fitted with an Intercooler to help prevent the onset of pre-ignition and/or detonation. Fuel was delivered via Multiport Fuel Injection. Bore is 83 mm (3.3 in), and stroke is 83.6 mm (3.29 in). An electronically controlled fuel injection system was used with 370cc injectors. It was used in the following vehicles: 1987-1988 Silvia S12 RS-X 1989-1990 Nissan Silvia/180SX S13 (International market) 1987-1989 Nissan Bluebird RNU12 SSS ATTESA Limited (Japanese Market) 1989-1994 Nissan 200SX RS13-U Europe. 1985-1990 Nissan Auster "1.8Xtt" and "Euroform Twincam turbo" There were 2 versions of the CA18DET available, yet only one was produced for Japan. The late model Japanese CA18DETs received 8 port (low port) heads, with butterfly actuated auxiliary ports in the lower intake manifold which corresponded with 8 ports in the head. Below ~3,800 rpm, only one set (4 ports open, 1 per cylinder) of long, narrow ports would be open, accelerating the intake charge to the cylinder. This allowed for quick spool and good low end tractibility. At the 3800 rpm change over, not only would the ECCS shift into batch fire (as opposed to sequential) fuel injection, but it also opened the second set of short, wide ports (8 ports open, 2 per cylinder) which assisted in high RPM flow. This motor is known for stronger torque characteristics, as well as faster spool at lower RPMs. However, due to displacement-based taxation and cost of emissions testing in Europe, the CA18DET was sold as the only available engine in the S13 chassis 200SX (Euro model) until replaced by the S14 in 1994. The Euro motors received the 4 port (high port) head and intake manifold, as well as revised ECCS ("Electronic Concentrated Control System") parameters. Power was not increased, but high RPM flow was indeed improved, making the 4 port CA18DET the most desirable of the late generation Nissan turbo 4s.

Nissan CA18 turbo powered Toyota Corolla
Aaron's Toyota Corolla KE70 caught our eye recently at Heathcote Raceway. The car is now powered by a Nissan CA18 turbo engine complete with some select bolt on upgrades including a HyperGear TD06 turbocharger and E85 fuel system that delivers over 400hp to the rear wheels. A new forged engine is in the works with Aaron hoping to have a crack at the 10-second barrier. 1982 Toyota Corolla KE70 Nissan CA18 18L engine [ ARP head studs, Cometic MLS gasket ] Stock bottom end turbo: HyperGear TD06 20.5G @ 26psi Speedtek manifold, twin Tial 38mm wastegates Exhaust: Havoc Fabrication 3in stainless E85 fuel system: ID2000cc injectors, Bosch fuel pump ECU: LINK G4+ Gearbox: Nissan RB20/30, CA bellhousing ] Diff: Borg Warner 28-spline from Skyline Suspension: BC Racing AE86 coil overs Brakes: RX7 calipers, Mini Cooper discs Power: 304kW / 407hp @ wheels Best ET: 11.30 @ 131mph Tuned by: Trent @ Chequered Tuning Heathcote Park Raceway, Australia ~ May 24th 2015 Get your track gear!
