Ok guys, I've decided to go through with it but i dont know what to expect.

My car is sitting at around 70mm off the ground,

ive got a pod filter,

3inch turbo back with a 5inch tip,

fmic,

boost gauge (on my a pillar),

boost controller (bleed valve),

atmo BOV

i just want to know wich mods the certificate will cover and what ill have to do to get them all covered

you're joking right?

right now you'd get defected for:

- ground clearance

- unshielded pod filter

- boost gauge on a-pillar (unless it sits lower than the highest part of your dash)

- boost controller

- atmo bov

I suggest you fix these up before wasting your time and money trying to get it engineered.

i already have been defected for all that...

but if all that was fixed then i wouldnt need it to be engineered. it would already be legal.

i dont understand what the whole point of having an engineer certificate is if everything has to be legal before enginneering.

well thats exactly what im saying i just didnt know what a engineer does

guys, the engineer isn't a magician, he works within the guidelines set by the RTA. he's there to tell you what is legal on your car and what is not. then when you have everything that is legal he will give you a report stating that fact and the police will not bother you. if on the other hand you have a certificate but still display pods and gauges on pillars etc you will get done.

You kno wi dont mean to sound drab,but why dont the engineers certify a cars emmissions as well!Im thinking that they (government-police & epa) have it his way to make more money from society through tyheir fines etc.

Think about it if there were emmisions tests at the engineers then we could slap them with a cert.

But then on that note they could be doing it the way they do it for reasons like.Not being able to trust the people involved,with the testing,to be honest.

End Rant and sorry for thje thread hijacking and not being on topic.

its not about the size of the rim... its the distance between the inside of the rim and the chassi of the car.

i think they make the space bigger by maybe adding spacers and I THINK they take a chunk out of the inside of the chassi to make the space bigger. im not 100% on that though

If you make major modifications or repairs to your car then it requires an engineering signatory to ensure your vehicle still complies with the ADRs. Its not a matter of just "getting it fixed", and its not something that you need to do only after you get defected. If you weren't modifying your car in a half-arsed way, then you would have already obtained the certificate before driving the car around.

The point of an engineering certificate is to have a qualified and independent person validate that your vehicle is still roadworthy. The engineer doesn't actually do any work on your car. They look at someone else's work and ensures that its not dodgy. That's why you need to have the car legal before taking it to them, so they can sign off on it.

but id at least want my rims, exhaust, pod and lowering engineered. i dont want my car sitting any higher than it already is.

Fact: your car sits 30mm below the legal minimum.

So your desire to have your vehicle's lowering signed off by an engineering signatory is mutually exclusive to your desire to not increase your ride height.

So which one do you want more? Because you're not getting both.

If your engineering signatory does a dodgy and signs off on it anyway, the moment a cop measures the distance they'll defect you anyway (since its clearly not legal, no matter what your sheet of paper says), and if you say that your engineer signed off on it then chances are they'll investigate him for abusing his powers and have his signatory powers removed.

100mm is what the minimum is.

Pod filter is technically ok so long as it's not louder than 90db.

The exhaust will be ok so long as it's got a cat and not louder than 90db. Mine was tested at 3000rpm from 30cm or something.

Atmo BOV = no chance.

Everything else is up to whether or not it's safe.

Good luck.

how do you go about getting say a set of 19in rim enginered on your car?

From my interpretation of the Vehicle Standard Information (bearing in mind that I'm not a lawyer), there's no limits to the diameter of your wheel.

The VSI No. 9 (Guidelines for alternative wheels and tyres) states that your wheel track may not increase by more than 25mm. Your alternate wheel may not be more than 26mm wider than the factory rim without an engineering certificate. The outside diameter of your wheel and tyre combination can not be more than 15mm greater.

This means if your OEM wheel is 13x4, you can legally run a 22x5 rim if you can get it under the wheelarch and find tyres with a low enough profile without needing them engineered. However, a 13x5.5 wheel requires an engineer's certificate.

my car is only sitting 30mm lower than the legal limit because of the sideskirts.

it doesnt matter does it? its the lowest point of the car

man that sucks.. to raise it i think ill just get 20's ;)

the 100mm minimum is measured from the lowest point of the car. So whether its your front splitter, side skirts, or exhaust pipe, everything on your car has to sit at least 100mm off the ground.

    • Found the answer: it wont fit without a bit of work- you'd have to change the guards as well
    • Ok cool, because I do have some OEM BMW options for light(er) wheels. 17x8.5 M Sport wheels are 11kg and I could put 255's on them. Maybe that's an initial test.
    • So, in the effort of pulling apart airboxes and testing enclosures to see if this aids in MAP loss at WOT I noticed: 1) The ducts up the OEM intercooler holes from the front bar help IAT drastically, whether the pod is shielded from the engine bay by an airbox missing a lid, or an airbox WITH a lid. Plus you get more induction sound without the lid. Having half the airbox (with no lid) acting as a barrier to the headers seems to help. 2) For shits and giggles I checked the TB. This was full pedal travel. This is actually full travel of the TB. Photos aren't perfect, but there was definitely an amount of play in it and it wasn't against the stop. After much swearing and adjusting the pedal, I realised that the cable is actually too long for the skyline pedal travel to fully articulate it. Having the pedal adjusted so WOT was actually hard open on WOT resulted in an idle of 3500rpm. As an aside, this was also the TPS registering at 3.1%. I removed the above to give the pedal enough travel to actually fully open the TB. I now get a satisfying 'thonk' on full open and full closed which you can hear pumping the pedal as it hits the TB stops (with the bonnet open and intake back on). Luckily for me, the screw screws into a raised metal boss under this plastic piece that is now acting as the new throttle stop. I've gained about 20mm (ish) of pedal travel and I can move it maybe a mm or two post open-thonk before it's hard against the stop. After all of this I did a bit of road tuning because a 102MM throttle is sensitive. The difference between holding an 950rpm idle and instantly stalling is about 0.4% of TPS movement. Will that help? I suppose it can't hurt. I set 'closed' point back to where it was, I can definitely feel the extra pedal travel that is needed to actually open the TB fully. But this morning I dropped the car off at Paint Jail again, so who knows when this will re-eventuate out to see if it helps with the top of the dyno hitting a ceiling.
    • Take heart that everyone else seems to have found a way. The OEM S1 indicators do slot in pretty firmly. It may simply be a case of having them sit slightly looser and nobody actually ever noticed this when attempting to remove a indicator from a JSAI bar :p
