hey dat51k, yeh in nsw the law states something like, if it is more than a 15% increase then it needs to be engineered. So an A14 doesnt need engineering but an A15 does Im pretty sure. Thats prob why everyone has A14's haha

I thought that it only needed a engineers cert if it required any modifications to be made to fit the motor.

Not sure on ya laws there , but here Melb, Ive had an A14 in my ute for 20yrs. Its been reg off and on for most of its life and up to 3 yrs ago when I last rego'd it , was never asked for engineers. Even now I presume if I re rego it they wouldnt ask me. So I presume your a15 had been rego'd before or was it put in after it was rego'd??

yeah i know this but if i was to buy a ute with an a15 already in it and running would it need engineering in NSW?

If you want to save on engineers and your building the motor up, just stroke

hey guys im in the process of buying another datsun and found one im keen on. question is will i need engineers cert for an A15 in a ute? last i heard biggest you ccould go was A14 without one. in Nsw. anyone shed some light on this??
