I need help, advice and suggestions. 1993 6-Seat Commodore VR.

Pretty much all mods affecting performance are illegal as far as in aware.

The lukey cat-back will be nice, not too loud but gives it a note.

The high flow cat will likely bring on your engine light unless you get a custom tune (not worth it unless you're going to boost it).

The 2* cooler mod would be an online resistor to the intake air temp sensor NOT o2 sensors. Never used one, maybe someone else can elaborate...?

Cold air intake will be more noise than anything else, but you'll probably notice a little gain in engine response. Either do one of the many "do it yourself" airbox mods, or buy a mace engineering one.

Plenty of things you can do if you want to spend money, like a tune, higher ratio rockers, bigger throttle body, extractors, etc. but it'll never be a rocket. Likely to put a smile on your face if you have a few grand to waste...

 

The exhaust should be good as long as its not to loud as for re-tune with hiflo cat Ive never heard that before. extractors and hiflow cat with that cat back should free up a few ponies as for legal if its not loud you should get away with it if its not p plate legal.Forget number 4 totally, contacting greenfoam can be difficult but he is not expensive and i have used 2 memcals done by him both with minor gains on stock motor..
Mace or even factory type cold air intake with good filter (like a k&N) wont give noticeable gains in itself but with everything else as a package and along with proper servicing its about as much as you can do with out getting into definite p plate restrictions.

I would you suguest you peruse the RTA P1/P2 Licence restriction page. It can be found here.

Specifically, this section:
Prohibited vehicles
The prohibited vehicle condition restricts provisional (P1 and P2) drivers from driving certain high performance vehicles. The condition applies to provisional licences issued on or after 11 July 2005. The scheme aims to prohibit young driver access to vehicles that are overrepresented in young driver crashes.

Prohibited vehicles are those with:

•Eight or more cylinders.
•A turbocharged engine (except diesel).
•A supercharged engine (except diesel).
•Engine performance modifications that require an engineers' certificate.
•Certain high performance six cylinder engine vehicles or other vehicles as described in the publication Novice Drivers - High Performance Vehicle Restrictions.

As far as I am aware, exhausts, cold air intakes, high flow cats, computer re-flashes etc are not mods that require an engineer's certificate. In fact I think the list of mods that need an engineer's certificate is basically limited to turbo and superchargers which are prohibited in any case.

In any case, I've been driving for two years on my P's and have been in my Commodore for a year and a half. In this time, I've been pulled over for a few breath tests and all could be described as "routine" with one exception when an officer was "suspicious about why I was on the road at 4:00 am", which to be fair probably was valid given the time and place. In no instance did any officer inspect the vehicle in any great detail beyond briefly checking the tyres, which were all roadworthy and possibly making sure the lights that were on were working. I don't have a modified exhaust, nor do I have any outward signs that the car has had it's performance modified. I've kept the stock alloys on, haven't lowered the car. I don't "hoon around", developing a reputation for doing the wrong thing. In short, I don't give the police any reason to suspect that there is anything untoward under the bonnet. I would hazard a guess my driving experience would change if the car had a loud exhaust, was lowered to within an inch of the ground, with big 20's on, while I was constantly powersliding my way around every corner like I thought it was a drifting contest.

Bottom line is police have better things to do than comb over some kid's car to see if it might be modified, if they have no reason to believe it is. If however you give them a reason, that changes everything.

 

Only thing I can see on that list that would give you any trouble is if the exhaust is too loud, otherwise all sounds pretty good. In NSW we have it pretty good in some ways, as unlike some states where no mods are allowed at all on P's, we have fairly free reign to do as we please short of forced induction.

What do you mean by "gloss black stockies with trim rims", could you post a photo? I personally prefer the look of alloys over stockies or hubcaps, but seeing as mine came with alloys from new I just left them on. Tyres for 15 inch wheels are cheaper than 17 and larger, but you could probably pick up a set of 17's cheaply if you wanted to. 15" alloys are basically worthless, so if you're like me and just want some form of alloy wheel, then they might be worthwhile to look at. I picked up a set of 4 VN SS alloys for under $50 at an auction a few months ago, to give you an idea of what's out there if you're interested.
