For Questions Regarding WOFs/CERTs/NUMBER PLATEs

[cletus]

Im looking at installing rear seatbelts into my Mk 1 , 2 door escort. Im assuming i will need to get these certified? is there anything i need to know about specifics for installing them -or do they need to be installed by a professional to get certification?

Thanks!

yes that will need a cert, its no worries to fit them yourself, the main thing is to get them in the right place. Probably a good idea to go see your local certifier and get them to show you where to put them. The actual fitting of the belt is easy, you can buy `seatbelt doubler plates` they are basically one plate above and one below the floor, sandwiched together and riveted, then the belt bolts to that. there are a few other things like using the correct rivets, aligning the plates correctly etc, all that is in here

The story goes that there was some guys putting v8s in escorts in Napier trying to beat a rotary powered car and they kept crashing them, then there was a death and they tightened the rules on modifications. Dont know how true this is. Been told by more then 2 old mechanics in Napier

sounds like one of those stories you`d hear around a campfire from someone with a torch under thier chin..........

we are lucky to have a system that allows us to modify vehicles in this country.... i know sometimes it seems the rules can make modifying a car tough, but we can do pretty much anything to a vehicle, if its safe and meets the regulations. it came pretty close to not being able to do anything to a car or at least making it very difficult/expensive in the early 90`s

yea the foreman at work was telling us about that

i think we are incredibly lucky compared to say aussie where you cant put a 572 into a morris minor like we could as long as blah blah was upgraded too .

i love it .

They are trying to change the law in UK regarding modified cars but changing laws there is like paddling up shit stream in a barb wire canoe with a tennis racket for a paddle- a long process.

The way it stands in the UK is that if a car goes for an MOT and the tester feels that lets say the morris minor is not safe with a 457 chev and drum brakes all round then it wont pass. The truth is a lot of places just don't want to bother with extra digging or hassle - so long as it passes the criteria for a standard MOT its all good.

This is great if the cars are built with some thought about safety, which most are but Ive seen some really dodgy builds over there. Things that would have a cert engineer here wearing out pencils.

I still love the lack of certs in the UK though!

I'm happy to have to cert my car here if the other option was no mods at all like some states in aussie or half the European countries- but I think its bloody expensive! And I still cannot get over the fact a car will fail a wof if the parcel shelf has some holes in it for speakers!!!!!

If i was to cut the body off a hillman avenger leaving only the floorpan, firewall and running gear then graft it to the top half of a honda civic will it be certified as a civic or a avenger or is it classed as a scratch built ?

[CaMpylobacter]

If i change from a sohc engine to a dohc engine in the exact same family of engines, this will theoretically require a cert I'm led to believe. the engine literally bolts in with only changes to the exhaust manifold on the new engine, and some water piping. the engine looms more or less plug in from each car.

the car had examples which both came with and without catalytic converter. as did the donor vehicle from which the engine came from.Both in my case did not have these fitted given their factory spec/year. DO i need to prove that this is the case, and pass a stringent emissions test without a cat, or do I need to fit a cat, or what is the deal?

also, do I need to the cert or recert the vehicle if I add a quad throttle setup instead of the factory single throttle manifold?

IN another case. I'm looking to swap an engine from single carb, to quad bike carbs. Does this require certification? I doubt the power increase, if any, will be more than 10 or 20 horsepower which is well within the no-cert tolerances, but due to changing the style of induction I am a little bemused.

would probably be a scratchbuilt. and what a lovely motorcar it would be.

yes would need cert for changing to DOHC head. what sort of car is it?

if you can prove it then you shouldnt need one. as of may 1 any car being certed for an engine swap has to have a cat fitted IF the engine being fitted AND the car originally had one.

IE r32 skyline with RB26= needs cat.

r32 skyline with 265 chrysler 6 cyl= no cat.

valiant charger with RB26= no cat.

theres a few grey areas that i will need to find out about- theres a lot of cars of the same model that may or may not have had cats fitted from factory

no if it falls within the less than 20% increase then it wont need cert.

heres another handy thing to look at it tells you what you can do that doesnt need cert. its dated april 04 but i dont think much would have changed

pug 205 receiving a dohc xu9 form a 405. same capacity. 30odd horsepower more.

the jap import ones all have catalytic converters, as do 'later model' ones.

how far am I meant to go to prove this? I've still got the factory exhaust for both hah.

[73crownwagon]

if my car is certed for a holden 308 and trimatic gearbox but has been dereged when i re-vin does is the cert still valid?

dont really know yet havn`t had to deal with it so far.........but i would think a pic of the original exhaust, and the fact yours is nz new (correct?) should be enough

nope needs re cert

the chassis number wont match up because if its a re reg it will have a new 17 digit 7A8123456789 type chassis number instead of the old one

[Requiemk]

Awesome thread, is great your helping people out.

I have chopped a large section out of my firewall to accommodate an engine swap, is there an guide lines with re welding in some new steel in there?

The chassis tag happened be in the way, would you be happy for me to weld it back into the firewall at a different point as old position is no longer available.

I still need to build my exhaust, is any catalytic converter suitable?

meanage cheers guvnah.

the original exhasuts have also been replaced from the downpipe back at some stage :\ though.

hmm

may need to talk to some geezers down my way

tbh most wof guys wouldn't notice my conversion anyways. but I want to roll legit

damn was about to say thats the case with the 910 but alas you beat me to it . in fact not even the wof guys at work knew till some faggot dobbed me in .

[CaMpylobacter]

yeah

like rolling a citroen to a non-citroen workshop. it can have ANYTHING wrong with it and you pass just because you say 'oh nah mate, that's how they're meant to be'

[73crownwagon]

oh sweet thanks for that man, where abouts in auckland do you do certs? which shop?

[ryanfels]

if you can prove it then you shouldnt need one. as of may 1 any car being certed for an engine swap has to have a cat fitted IF the engine being fitted AND the car originally had one.

Ok so in saying that, my 1982 Toyota Mark 2 with a 2jzgte wont need a CAT because my car never had 1 with the orginal engine?

[rusty260z]

hi. I got a 200sx with ca18det,

i converted it from auto to manual,

everything was bolt on from wrecked manual car

looking at selling it, a guy came to have a look and said i needed to cert it

thought this wasnt the case, but do i have to cert it for conversion.

Ta.

[kyteler]

in theory you have to cert it. But some wof places let it slide. VTNZ missed it the first time on my sunny got me the 3rd time. sucked hard

I guess it could be read either way but as I see it as long as you change no mounting points and don't have to fabricate or change anything and can use original factory parts to factory mounting points then it's not something that requires certification.

Yep.

If I was told I needed a cert for a completely OEM parts swap I would make a fuss until I got my money back and go somewhere else.
