yeah look dude.. have fun! as you would know, its not a holden 308 or anything, its actually a real complex motor to work around! aftermarket parts yeah there are ok to work with, but pulling everything apart and putting all back together, all those hoses and wires etc! its a bit of a challenge i would say. if your confident, then i wouldnt hold you back. but if your sceptical, well, maybe think about it a little more before you start taking it apart and then say, sh*t, i cant do it cos then your in trouble! good luck champ
