| We have been developing this engine since 1987 in turbo form for rallying and racing, later backing from Ford motor company enabled us to develop a normal aspirated version which was used in the BTCC. and later the Portugese and French touring car champonships. 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. |
