A friend of mine who also competes ran an early Sierra Cosworth for several years in competition. Completely modified with around 500hp and a turbo the size of a large trash can ! Now he runs a Mitsi Evo
Broke the class record for the event at the last outing. Only his 2nd time in the car !
Completely stupid specification. Was mapped originally on special turbo fuel which we are not allowed to use in our events. Lost 100hp when taken back to "road" fuel.
Rumours are rife about this motor.... Most reliable rumour is 600hp.
Uses full launch control, traction control and passive ALS (not the flame popping BANG BANG ALS, it just growls on the over run). It's totally ace to watch
Of all the Cosworths I'd go for the most original Escort Cosworth you can find, preferably a "Monte Carlo". I think these came in Aubergine and are as rare as rocking horse sh*t in the UK.
Edit: Aubergine = Egg plant in US
