the person that had it before put the turbo on it some one said its a cosworth turbo or stage 3 turbo like i said i dont no much about em.wen i got it he said it would cut out bec of the ecu witch it does cut out in 4th wen u hit 4 thousand revs and 5th but now iv turned the boost down it does a 100mhp as wer wen i got it it would only do 70. i dont think it cuttin out on top end is to do with it not idleing wen its hot.but as soon as i can keep it tickin over il send it in to a garage to get set up.some one said it could be the icf or some in ?????/??
