Hey thanks everyone for all your help and reply's it clears a lot of stuff up for me!
As for plans in the future for my car, i'm not going to big power just mild really, if anything i'm more or less aiming at between 220-240 rwkw so i suppose the standard bits n pieces are going to be fine, i've read the N1 water pumps are good for high rpm driving which i dont really do cos its a daily driver not track or anything like that.
Chook - Thanks heaps for those part numbers they'll come in handy for sure!
(B1) MR_Fanny - The cam seals and oil seals... are they necessary to replace? My rocker cover gasket doesn't seem to be seeping much, looks all ok i think..
GTR32GUS - Thanks for that link dude! I'm just not sure if i'm up to doing it myself... i know bits and peices of a motor but i dont think i have all the tools needed for the job...
As for the waterpump, i've noticed a forum business trader is selling them for around $170 + postage, is that a reasonable price or would trade price from nissan be more cheaper?
Again thanks everyone for your help... its starting to clear a lot of stuff up for me
Oh and my waterpump is leaking when i turn the car on... i can keep topping it up but it seems to be making some funny noise now, dun want it to shit itself driving somewhere get a freaking tow truck lol
