We have fitted bigger engines to virtually all TVRs made including the Ford V6 based engines used in the M series, early Wedges and S series. Projects have included 5.2 and 5.3 litre Rover V8 engines into Griffs, Chimaeras and Wedges, 24 valve Cosworth engines into Tasmins and S series cars and so on. We have strengthened amd modified gearboxes and transmission as well.
