I have had this car for a work car and just seen that ppl were making them pretty quick. I was wanting to know what would be the best thing to get some more speed out of it. If i could make the car fast it would be a sleeper from hell. I was wondering thigs like if there was any other type of head i could get for the car . I was also thinking about doing a complete build up of a 2.5 and c what i could do. is there any company that sales any internals for these cars . And aslo thanx for any help i can get.
