Model & Engine Information
Here at LMF Vauxhall our staff members have extensive knowledge of Vauxhall & Opel back the 1980's. We have worked with several specialists over the years that have been involved with engine conversions and race spec tuning on many Vauxhall / Opel engines. Please see the list below of the some of the types of engine and models we specialise in.
13NB / 13SB / 13SH - 1.3 8v SOHC Vauxhall Nova, Astra & Opel Corsa A
This engine was fitted in the Vauxhall Nova during in the late 1980's and early 1990's. The engine is still used today in the National Autograss. It was fitted in the Iconic Nova SR 1.3. An easily tuneable engine which is still popular today with GM enthusiasts.
14NV / C14SE / C14NZ - 1.4 8v SOHC Vauxhall Nova, Corsa B, Astra & Belmont
A bigger bore bored version of the 1300cc whilst the stroke remains the same. The Belmont was a saloon version of the Astra and is probably more popular today that it ever was. This engine is also used in the National Autograss, mainly in the Class 3.
C20XE - 2.0 16v DOHC Redtop Engine SRi - Vauxhall Cavalier & Calibra | Opel Vectra A
This is probably one of Vauxhall's most iconic engine and is still very much a popular engine amongst enthusiasts. The original design has development from Cosworth and was nickname as the 'coscast'. These earlier coscast engine are more sort after as there is speculation that the cylinder head was of superior quality as opposed to the later head produced by GM. This engine has been developed by many race engine builders with record power achieved at 326BHP. The C20XE has seen extensive use in motorsport. Typical uses for the engine have ranged from hillclimb events, to open wheel racing categories. Despite its age, it remains the powerplant of choice for many Formula 3 teams and has most recently found acclaim in the Australian F3 scene where Tim Macrow, the 2007 Australian F3 champion, drove an Opel-Spiess powered car to claim victory. Tuned by Spiess, an F3 grade C20XE is easily capable of producing 250 bhp (190 kW) in its naturally aspirated form. Many aftermarket tuners have further developed the C20XE for racing purposes. The C20XE was used by the Chevrolet WTCC (World Touring Car Championship) team and the Lada WTCC team. The engine was also an option in Westfield kitcars.
C20LET - 2.0 16v Turbocharged DOHC Redtop Engine - Vauxhall Cavalier & Calibra GSi
A turbo charged version of the C20XE redtop engine. It produced 201 BHP as standard. The C20LET engine was introduced in 1992, and was fitted to the Opel / Vauxhall Vectra Turbo/ Cavalier Turbo, Calibra Turbo, and the South African made Opel Astra 200t S. It is similar to the C20XE, apart from the primary addition of a KKK-16 turbocharger, forged Mahle pistons, Bosch Motronic M2.7 electronic engine control unit and black plastic plenum/'top hat' shroud with a 'turbo' script. Boost pressure is 0.6 bars (8.7 psi) continuous with a 0.8 bars (12 psi) overboost.
Some versions of the engine implemented switchable Traction Control (commonly included in the early Astra GSi models). The inlet had a secondary throttle valve sandwiched underneath the primary throttle body. This is closed by a motor/arm assembly when the traction control ECU senses loss of grip/spin at the wheels. The engine was also equipped with a different throttle position sensor (six pin, as opposed to three), and a different coolant temperature sensor (which was black, as opposed to the normal light blue colour).
The engines that appeared in the early 90's also swapped the cast metal spark plug cover for a cheaper (and less regarded) plastic version. Those used round tooth cambelts while the later used square (with a plastic pre-tensioner). There are also subtle differences between the crankshaft, and visible difference in the pattern of the SFi airbox.
Z20LET | Z20LEH | Z20LER | Z20LEL - Vauxhall VX220, Astra & Vectra VXR
The Z20LET is a turbocharged version of the X20XEV for the Opel Astra G and features a 8.8:1 compression, 147 kW (200 PS; 197 hp) and 195 lb·ft (264 N·m) of torque. From 2005, the Z20LET engine was revised for the Astra H and Zafira B, to three different model designations, Z20LEL, Z20LER and Z20LEH. The differing designations denote the engine power output, 170 hp (127 kW), 200 hp (149 kW) and 240 hp (179 kW). Further revisions to the original design include under-piston oil cooling, a revised turbocharger unit and the deletion of the contra-rotating balancer shafts in the 240 hp (179 kW) Z20LEH engine (as used in the Astra VXR), to reduce mechanical losses. The Z20LEH also features high quality Mahle forged pistons, which are much stronger than the cast pistons fitted to the Z20LET, Z20LEL and Z20LER.
Z16LET | A16LET | A16LER | Z16LER - Vauxhall Corsa & Astra VXR
The Corsa VXR is a lively one, with 190 BHP from a small 1.6 turbocharged engine. As with all Corsa's it is light, nimble and handles as if it was on rail. It features ESP which is unattractive for some, but it may just stop you going backwards into the road traffic island ahead. 190 BHP and a heavy right foot will provoke a lot of understeer without it!!
The Corsa VXR Nurburgring Edition released in 2011 features a reworked version of the VXR's 1.6-litre turbo engine as well as a sports exhaust and a modified turbocharger system.
