sorry. i dont mean to sound so ignorant. i admit, the engines i build at work are to a set specification and no, i hadnt thought of it that way. ive built a few rs turbo engines for friends and although i no its very different, i just thought i could carry some of that knowledge over to my own engine. the engines i have built for friends have come with the parts they wanted me to fit. i just wondered if the parts i would need for a drivable 450bhp car would be a lot different. i no that building a 450bhp cossie engine is going to be a hell of a lot different to a 200bhp CVH but i was just looking for a few helpful tips. sorry for sounding like such a twat to everyone. i like to get on with everyone and just had a bad day yesterday which is why i was so sharp with u all. i apologise now and didnt mean to take it out on u all. thanx for backing me ziggy. sorry for bein a twat to u PJay

thanx all
