flyingbrick Posted April 10, 2019 Share Posted April 10, 2019 Its normal to change feom 4 stud to 5 when increasing engine power but would instead increasing stud size also make the cert man happy? Quote Link to comment Share on other sites More sharing options...

Does the cert become invalid if the car gets a MSNZ roll cage and is fitted with fixed back seats/harnesses with authority card etc? Cert plate would need updating to match the mods to the car. 1 Quote Link to comment Share on other sites More sharing options...

Yep that's one of the options in the engine and drive train standard Usually required for an engine swap that is heavier than original, ie a 302 into a capri- upgrade the wheel studs to 1/2 and that matches , for example, a fox body mustang- they were 4 stud, 1/2 studs and factory fitted with a 302 4 Quote Link to comment Share on other sites More sharing options...
cletus Posted April 11, 2019 Share Posted April 11, 2019 Obviously that comes with a common sense clause, fitting a big block chev into a fronte would not be made ok by fitting larger studs into factory hubs with matchsticks for spindles 2 3 Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted April 11, 2019 Share Posted April 11, 2019 I ask because my beetle will soon be ready for a drive (using an old 1200cc aircooled motor) but I went and purchased a 96 legacy turbo as a donor for a one-day-dream-build of the beetle. About to buy wheels and would be cool if the wheels i buy (4 stud) wont have to be replaced later on. Have never heard of beetle spindles being replace with larger, but haven't heard of any legal turbo two liter beetles in nz either. Doesn't really matter because it will never happen anyway lolololololol Also. Are weld Draglites/prostars legal for road use in NZ. I have seen them on the road a few times but that doesn't necessarily make them OK Quote Link to comment Share on other sites More sharing options...

If thats such a thing All certs are full certs, except a wheel and tyres update and partial/full return to standard. The amount of time difference between doing a "minor paperwork update" and a full recert is not that much so you might save a little, but not a whole bunch. Keeping in mind the certifier has to check that all previously certified mods are still compliant and that there are no other obvious mods that have taken place since the last cert. FYI - plating fee is approx $200 which is what pays for the LVVTA system, the rest of the cost is the certifiers time and their costs. (a plate reprint for a partial return to standard or a wheels and tyres change is about half that) Quote Link to comment Share on other sites More sharing options...

Have never heard of beetle spindles being replace with larger, but haven't heard of any legal turbo two liter beetles in nz either. I searched this one for a long time with the quad cam engine. Very hard but it is doable to keep the engines under the deck lid in the quad cam. The physical size difference is huge. And... they get hard to lower because they have sumps. Hope you do it but. 1 Quote Link to comment Share on other sites More sharing options...

Would that also cover fabricating a new upright as well? Quote Link to comment Share on other sites More sharing options...

Rhyscar Posted April 16, 2019 Share Posted April 16, 2019 Just wanting to check what I can do to my seam above my wheel in cert world. I have enough clearance (just) for full compression without it touching but just wanting to be doubly sure I can’t damage the tyre on a big compression. This is being built to do jumps on targa.. A double seam like this provides quite a lot of strength to a sheet metal folding so I’m not sure if I can cut it back then stitch weld a doubler over the gap or something similar? In the past ive bashed seams like this flat but that doesn’t seem like the right thing to do either. Quote Link to comment Share on other sites More sharing options...
tortron Posted April 20, 2019 Share Posted April 20, 2019 Looks like someone tried to re register my new Morrie in 2016 It failed. I imagine due to rust and possibly wrong engine. Will it now be flagged for rust and il need a repair cert? I'm going to get replacement chassis horns and seemlessly replace the whole lot 2 Quote Link to comment Share on other sites More sharing options...
