Hi guys. Umm yeh i agree stealth, i got no intention of doing this kind of stuff myself cause i dont know squat about mechanics, just try to get a rough understanding of things thats y i wanna get an apprenticeship as mechanic, not to get a trade more for personal interest cause they get paid f**k all. I just wanna work out roughly what parts im going to need to buy and how much cash im going to have to need to get em. I dont wanna just fix my engine then have to go through and change shit later on when i get stuff done to it, thats y i mentioned i wanted to get round 300hp further down the track which isnt too hard out of a 25. I appreciate the help you guys have offered me, i never thought forums would be so useful. Thanks for puttin up with my lack of understanding and explaining stuff in detail for me. About getting the rebuild stealth, i was thinking if i get a rebuild, its done i know its all sweet wont have to change stuff, whereas i buy another engine, i dont know wat problems it may have. I basically just want to do this right the first time, so i dont need to worry bout it again.
