Yowzer Posted November 22, 2013 Share Posted November 22, 2013 Best bet is go consult with your local cert guy. Being that the engine is quite visibly different it may attract a lot of attention come WOF time, that even if it's not required it may pay to get a cert anyway. It also gives you the opportunity to do other things if you so please, such as new seats, adjustable suspension etc Quote Link to comment Share on other sites More sharing options...

bobdylan Posted November 22, 2013 Share Posted November 22, 2013 Yowzer i did for my car. Cert the engine, suspension, brakes, half cage, stripped interior, light pod. Incase i get stopped by the cops. It was more of a budget build, he didn't have a lot of money. Was cheaper then rebuilding 16v. Quote Link to comment Share on other sites More sharing options...
johnnyfive Posted November 22, 2013 Share Posted November 22, 2013 Ltsa favours Honda. Makes it hard for the rest of us I don't, I mean, You, what? The rules are the rules, and are written to cover a VERY broad range of vehicles. If you find someone who interprets the rules differently then by all means go for it. SiR EG Civic is originally 1.6 yeah? And there is a cert guy saying a 1.8 swap doesn't need a cert? Rules say no. Pretty black and white.

cletus Posted November 22, 2013 Share Posted November 22, 2013 Ltsa favours Honda. Makes it hard for the rest of us. They can drop a b18c in with no cert into a eg sir, yet us Toyota fans are screwed. Its a outrage. incorrect. fitted a cert plate today on a civic that had been pink stickered for this exact reason. ltsa doesnt exist any more, they keep changing, its NZTA now they probably dont care whether civics or corollas are better. your 20v vs 16v head issue- cert it if you want no problems dont cert it if you want to have a potential argue every wof or when you get pulled over. even if you are technically correct, someone will have another idea, especially if you fail the attitude test Quote Link to comment Share on other sites More sharing options...
Bling Posted November 22, 2013 Share Posted November 22, 2013 But 4age 16v smallport vs silvertop 20v isn't over the 20%. As I mentioned above, the only time 20% comes into anything, is when modifying an engine. It might be hard to convince someone you modified a 16v small port into a 20v. If you are swapping the engine, check the list I posted. Unless you can prove a 20v makes the same or less power than the 16v, then you're out of luck. Just how I read it anyway.

ae85 fiend Posted November 25, 2013 Share Posted November 25, 2013 Hey Cletus, can you fail a cert on having solid mounts? the 1UZ that i've got in my te31 corolla has just failed its cert today because of the moutns being solid and rust the size of about a 10cent coin in one of the guards. Cheers Quote Link to comment Share on other sites More sharing options...
cletus Posted November 25, 2013 Share Posted November 25, 2013 are they proper solid mounts or are they nolathane with a bolt thru it? Quote Link to comment Share on other sites More sharing options...
ae85 fiend Posted November 25, 2013 Share Posted November 25, 2013 are they proper solid mounts or are they nolathane with a bolt thru it? Proper solid mounts The cert guy is also trying to make me beef up the front suspension as well? Even though the V8 weighs less than the standard engine it came out with?

Even though the V8 weighs less than the standard engine it came out with? odd hobby car manual says you can have solid mounts, it was changed a little while ago so you can have solid engine mounts and rubber gbox mount, before that they had to be all solid or all flexible Quote Link to comment Share on other sites More sharing options...

Testament Posted November 25, 2013 Share Posted November 25, 2013 are they proper solid mounts or are they nolathane with a bolt thru it? whats wrong with a solid polyurethane (otr alloy or whatever) mount with a bolt through it? I dont see how it's any more dangerous/prone to failure than a factory bonded rubber thing? if either nut comes loose on the factory mount the result is the same as the bolt coming loose on a bolt through mount?

cletus Posted November 26, 2013 Share Posted November 26, 2013 the only reason you could have for using a poly bush with a bolt thru it as a mount, is for the poly bush to reduce vibration. but the bolt transmits vibration anyway as the bolt and nut are both attached to the things that should be isolated unless you leave the bolt loose enough that it doesnt transmit vibration as much, in which case it isnt tight enough to hold an engine in. if you tighten the bolt properly then the poly bush gets squished out eventually. no problem with using a solid material like aluminium or steel though Quote Link to comment Share on other sites More sharing options...

cletus Posted November 26, 2013 Share Posted November 26, 2013 early fords used a mount with a thru-bolt, but is fully isolated. boss got me to use these in an engine conversion i did, they sucked, ended up replacing them with normal round rubber mounts 2 Quote Link to comment Share on other sites More sharing options...

I have some same of this I was considering using that are bolt through like that. I don't think it will deform measureably under sane amounts of bolt tension/torque ratings up to one standard tom Quote Link to comment Share on other sites More sharing options...
