We have been developing this engine since 1986 in turbo form for rallying and racing, during 1987 we built the first normally aspirated version. In the photograph John oversees the first prototype to run on the test bed which led to backing from Ford Motor company enabling us to develop a version for the BTCC. In 1991 we built engines for the BTCC, Portuguese and French touring car championships. We offer a range of kits all which have been tested and race proven whether turbo, normally aspirated, 2 litre, 2.3 or even 2.5. We can tailor build this engine to suit your requirements.
