do i have to engineer a 86kw 4age in a sprinter? from what ive read of the rta guidelines it sounds like all i have to do is get the engine number changed is that correct?
what about a 4agze? does that have to be engineered? again from what i can understand it does not.
PS. im talking about in NSW
thanks

4agze definatly, it's had forced induction added. now from what I've heard some people have snuck 4age's past but I think it may need a engineers report too. I'm sure other will tll you soon enough

<15% capacity increase = no cert unless forced induction
> 15% or engine from different mfct or forced induction then cert is rqd.
Her's an excerpt from vsi09
Do I need an engineering signatory for minor modifications?
Vehicle modifications fall into three distinct categories:
? ?Owner certified? minor modifications which can be accepted for registration purposes without
formal certification;
? ?Engineering signatory certified? modified production vehicles; and
? ?Engineering signatory certified? individually constructed vehicles.
Owner certified minor modifications are generally those modifications which were optional equipment
for the vehicle concerned. Owner certified modifications also include some non-standard modifications
of a minor nature which do not affect the level of safety, strength or reliability of vital systems such as
brakes and steering. These modifications have little or no impact upon the vehicle?s level of compliance
with the Australian Design Rules.
Examples of minor (owner certified) modifications are:
? engine changes where the capacity increase is less than 15% above the maximum size engine
available for the vehicle (providing no major structural modifications are necessary and where
noise and/or exhaust emission ADRs apply, all standard equipment such as carburettors, exhaust
systems, exhaust gas recirculating valves, oxygen sensors and catalytic convertors relating to
noise and emission control are retained and operate correctly);
? the fitting of a proprietary sunroof (if the modifications are of a minor nature only);
? fitting a ?package? available as optional equipment for the vehicle (eg front disc brakes, power
steering, alternative transmission and bucket or bench seats);
? additional lighting eg: fog & driving lights;
? alternative wheels and tyres within the owner certified limits set by the Authority (see Vehicle
Standards Information Sheet No. 9 Guidelines for Alternative Wheels & Tyres);
? fitting of handling enhancing suspension components such as roll stabiliser bars and up-rated
shock absorbers.
Major modifications which fall outside the category of minor (owner certified) modifications, require submission of certification by an engineering signatory. This is usually in the form of an ?engineering certificate? prepared by the signatory. The original of this certificate is generally required to be submitted to the RTA for notification of the modifications or for registration of the vehicle. The duplicate copy or owners copy is stamped and endorsed by the RTA and must be kept in the vehicle and should be presented to an authorised officer of the RTA or the Police when requested.
Does the RTA require notification of the modifications?
Modifications made to the motor vehicle or its equipment which affect registration details must be reported to a motor registry to ensure that accurate records are maintained.
These details include, year, make, model, variant, shape, engine capacity/number, vehicle identification number/chassis number, tare weight, gross vehicle mass, and aggregate weight.
If the unladen weight has changed, the owner must provide a weighbridge ticket for the vehicle in its new configuration.
I can email you the full doc uf you like let me know

I had to get my 88kw Blue top engineered and a blue plate stamped in the engine bay.
As far as I understand, if your car model released in Australia did not come standard with the engine, you'll have to get it engineered (or so I was told) as a rough rule of thumb.

i put a 4age in an ae71 corolla, and just told the rta about the engine number change, they then sent me a letter for the car to go over the pits, & they just had a qiuck look under the bonnet to make sure averthing was sweet and away i went, no engineers report required

so am i correct in assuming if i swap a 1600 SOHC for a 1600 DOHC there is no capacity increase and therefore no engineer cert required? just a blue slip and change of engine number? please correect me if im wrong.
that Doc would be great thanks Clubagreenie!
thanks

no you dont have to just a number change its like if you were to keep your block and change all the bit over to it head, pistons, crank,etc you wouldnt have to do shit as its still a 4a but injected and then nothing would be needed.but if you feel you want to get it anyways for peice of mind.

technically you need to get it engineered because it is greater than a 15% power increase, its like 50% 
Some blue slip places accept just an engine number change, but I have heard of some saying NO.
I got my numbers change from a guy in Brookvale, which shouldn't be far from you, im actually in northern beaches to.
This guy initially told me I needed engineering then I told him its the same series motor and he goes if engine number starts with 4a0 then ur fine..... and it does so $25 later and a trip to RTA, number were changed.... its also passed a pink slip with it in there.
No cop checks under bonnet though yet.

The standards only relate to a 15% increase in capacity not power when knowing whether or not you need a cert. The only mention of power is in relation to making sure that other driveline parts are adequate.
The other chart relates to maximum capacity that can be fitted, this varies by original engine, chassis config (full or unitary) and induction. Thats why you can get away with 5.6 litre turbo or 6.5 litre n/a in the crown (except you cant turbo over 3lt).
I went from 2m (2.25 lt, stuff all of about 50hp new I think) to 5mge (twin cam 2.8 lt 145 hp new) only needed engine no blue slip and I took it to RTA first. Friend has fitted 20v to 1968 1600s corona and as the coronas came with a 1600, same deal, didnt even need the supra box engineered as the also came with a 5sp in some models (gt5).
Youd be unluck if you got a cop that knew the difference between the c and the g in the codes, but you could always get a new 4ac sticker for the front engine cover.
Have emailed the doc to you.
