Hey guys,

Just curious in regards to the p-plate laws that state that no p-plater may drive a car that has had any modification to the engine that requires an engineer's approval.

I wanted to change the cam gears, camshafts, pistons, valves and crankshaft...as well as lighten the flywheel...not allowed? or allowed?

Cheers guys,

Cartz

you could pretty much garrantee doing that stuff would be illegal, part of the p plate law is law against engine modification.

That said, they would NEVER know, all that internal stuff they could never find out, you've just gotta make sure you keep the engine standard looking, i'd be keeping the airbox with a highflow panel filter, stock exhaust manifold, high flow cat, stock turbo exhaust? just make sure its quiet. you dont want the car to sound lumpy, but if you sort the vct properly (r33?) it should idle pretty smooth, 60mm nissan tb, hide the ecu, dont have any rice inside the car or engine bay, or outside the car.

that intake and exhaust would really lose sfa performance, and considering that means the cops wont even look twice, its you best option. What counts is whats in the engine :O. Decent cams, good compression, balence, tune, the right headwork and it will be a weapon. what do you mean crank shaft?

Question - Allowed or not ..

NOT ALLOWED TO DO ANYTHING UNLESS YOU OWNED IT PRIOR TO LAW INCEPTION, OR YOU HAD YOUR LICENCE BEFORE LAWS.

Question - Will they know?

No chance unless you sound like you've got a 9 second engine running .. You know cams etc..

Yeah, i was also thinking of doing an exhaust and what not...but the main part of the law stated that it was only NOT allowed if it required an engineer's approval post-modification...

Do cops usually take off the timing belt cover? If so, it probably wouldn't be a smart thing to change the cam gears..

I was gonna put in a forged and lightened crankshaft...

No Aftermarket ECUs are allowed?

Wouldn't it be good if there was a thread that simply stated WHAT legal modification are allowed on the new p-plate laws?

Basically, i'm going to see how much power i can get out of an rb25de...but i want to do it legally, and not cut corners...(nothing beats the sound of a properly tuned and modified NA engine)...

ECU they can check.. Timing belt cover they wont take off.. To much effort/risk involved.

If you get HWP your going to be nailed .. But its just a $200 fine and 3 points I think.. 1 Yr isnt much to wait .. Just save up a shitload of cash for a RB26 conversion :no:

Well if that's the case, why not just save up for a turbo?

It's also 2 years where i am...

3 year total if you've just gotten your licence...

HWP?

They never would, and probably wouldnt know where it was

the cam cover would NEVER come off the engine.

The whole point is, you drive around in a stock lokoing car, stock interior and stock engine bay, they'l send you on your way within 30 seconds. just be polite and say you just drive it for the badge, but you know its a jap taxi and its good on fuel being only a 2.5L etc...

you have nothing to worry about, as long as its quiet, which i personally prefer anyway (for a daily), because you can get infront of people without everyone looking at you like your a hoon criminal.

edit: the only thing you'd have to worry about is emmissions, which i highly doubt would be tested on a 'stock' exhaust, and with a decent tune on some good fuel (gogo E10) with o2 working and cat, aslong as the cams aren't outrageous, you should still pass ok. BUT once again a stock car, you wont have any problem.

exactly! my car has minimal asthetic mods and looks stock. never in my 4.5 years of owning it have i been pulled over because it was a skyline. RBT yes of course.

don't drive like an idiot, don't attract attention to yourself and you're on a winning formula.

i havent even had my skyline for 3months and ive been pulled over 6times by the popos. mine is completly stock and they have gotten under the hood and made me rev my stock exahust. im pretty sure exahust, filter and extractors are all legal, not sure about the rest, but what cant be seen cant be tested. they wont pull ur motor to find out if anything is suss.

keep it nice n quit n clean and u will be fine. or save ur money n buy a turbo when ur off ur p's n start modding it then.

I feel important to mention hes a P plater, its like driving a car with DEFECT as the number plate..

But I suppose they do it for a reason, prevention of speeding because you always get pulled over...

Any yeah they do look for the ECU, they had a nice run of it in sydney a yr ago.. Its not common tho.

Is there any way to hide the ECU? say...under the center console?

as i said previously, check with your local state's rules and regulations into what you can or cant do.

trying to hide mods is all good and all, but in the end you will void your insurance. also keep in mind alot of cars come from factory and don't even meet ADR requirements.

you have answered your own question in the first post.

Personally, I'd wait till you are off your Ps before doing any "major" engine mods. Best to avoid the hassle from the boys in blue. The only change I'd do is put a K&N panel filter - but i'm not sure about the "legality" of this.

For now I'd recommend some sort of suspension/braking upgrade to start off.

      I'm going with "Just run two gates". Fix the problem conclusively. It's the only way you'd ever truly know, right?. This is all pretty much splitting hairs. Even the extreme example where it takes two whole seconds at 100kmh or something sounds monstrously dubious. And anyway, when you're punching the throttle when you 'need' this power, you aren't at 2800rpm in the wrong gear. Test it at 5600rpm in 3rd gear, when you're traction limited punching out of a sweeper. Much difference there when you account for traction?

      One Headlight isn't working - Driver Side Fuse Keeps blowing

      And the full R32 GTR wiring diagrams are also freely available. Hmm.... there's supposed to be an auto replace that would have linked the thread. Here it is, manually

      By dbm7 · Posted

      Ahh...should have been clearer ~ there's 2 ... SMJ = super multi junction (connector)...   ...this is connector 6 & 25 in above image -- body harness to engine loom (6) & body harness to main loom (25) Headlights go to front via connector 6 ; fuel gauge goes to tank sender via connector 25  ...like I say this is R33 diagrams, but at a pinch R34 won't be too far different. *IF* the two ground faults are related, this can be the only place where both wires converge (as one runs to the back, the other to the front)... ....thing is, you probably need to establish if the faults are related (unless you examine that area and find obvious chaffing on the looms there to body ground)....*IF* the fuel gauge is still broken (full needle deflection), I'd be headed for the boot, remove fuel sender wire, key on and measure the voltage there ~ it should be roughly 10volts. If that's ok, check sender to ground resistance...if this is a dead short to ground (and there's fuel in it), then sender has failed or something funky has happened to wiring in the tank. edit: ahh...rereading the thread, this is R32....above fuel sender test still valid tho'

      Rb25det timing belt position on cam gear

      By drifter17a · Posted

      I just changed the timing belt on my RB25DET NEO and wanted to get some opinions. I’ve been super cautious, did a lot of research, and took my time. I’ve driven the car, and it runs fine. After warming it up, I revved it to 8000 RPM a few times—no issues, everything held up.   After the drive, I heard a noise that I think is either the clutch or possibly a tight accessory belt. It’s not constant, just comes and goes.   I took the timing cover off to double-check everything:   Belt is on properly, Tensioner is tight, Did the 90-degree twist test—belt isn’t too tight or too loose.     What still worries me is that I noticed the belt seems to sit a little toward the front edge of the gears, especially on the idler pulley. It even looks like it’s slightly coming off the edge there. Is that normal?   My old belt (5 years old, ~3,000 miles) also showed a bit of wear on that same edge, so maybe it’s just how it sits? I’m probably overthinking this, but since it’s my first time doing this on a NEO and the engine is forged, I really don’t want to mess anything up.   Also, I’m thinking of swapping to a clear front timing cover with the glass window. Would you recommend NITO or HPI? HPI looks reputable and their covers have 2.5mm thickness, but not sure if there’s a real difference between the two.   Any advice or reassurance would be much appreciated!
