spud your in luck mate because the mechanic is talking rubbish. My CA18DET ute was engineered in NSW originally (I can get the engineers name if you would like me to send it to you). My ute was originally engineered with the drum brake rear end and Mitsubishi Verada discs with Commodore calipers up front.

When it came to getting the ute re-registered in the ACT I had the whole thing re-engineered with a borg warner diff and VN V8 rear discs and calipers. The new certificate also includes the EMS computer, FMIC, BOV, boost controller and ram pod though you may have some trouble getting these on a NSW certificate.

As Chris said ring up an engineer and follow his guidelines. The reason you get a car engineered is so you know that the car is safe.

Just as a side note, you are able to get an SR20DET 1200 ute engineered in the ACT (not NSW). I know this because we have checked it out with our local engineer and he has already done one we just have to follow his guidelines.

Cheers

I paid $300 for my mod plate that covered 7 mods. Engine, gearbox, fuel tank, diff, brakes, suspension and seat.

In NSW The engineers certificate costs from $280 to $500, depends on engineer and number of mods. Budget for $400.

Then $20 - $50 for a weighbridge certificate.

Then Blueslip (roadworthy - decent 30 minute inspection) $70ish, then off to the RTA registry to change the details.

Chris.

what are the costs of mod-plating/engineering ect, dont think ive ever read it here?

Not the right way to go about it.

Find an engineer, ask them what is required..and follow their requirements.

It's true that different engineers require different things. So don't go down the path of thinking you know what's required, because you might get a rude surprise when you find you have to "undo" some of your good work, before a reputable engineer will pass it.

How would you feel if some young fella killed himself, because you'd signed off on a non-roadworthy conversion?

But sure, it can be done. Just read through the various posts on the costs of approval/transplant, before thinking you can get out of it for less than $5000.

It took me 5 different engineers looking at my ute before i got it mod plated. There is no problems with fitting a CA18DET into a 1200 ute. When i got mine done he just said that as long as the conversion looks like it has been done properly then it is passible. My engineer would not even do a road worthy on my ute after he finished the mod plate because of my lack of interior. He still did the mod plate though! Don't listen to your mechanic, just go to the next one and try again or tell them that it is legal and that they have to pass it.

so is it possible or is the equation crap???

That's what we are talking about..

A 1200, because it's lighter, can only take a 1800 turbo or 2300 NA.

But you have to go off the weight that the RTA published for your car. Which has been discussed before, and is quite a bit less than the weight on the road.

In other states, they allow the modifier to add lead weights to bring up the weight, allowing bigger engines...but not in NSW.

Chris

so if using this equation i can put a 2.3L turbo engine in my 900 odd kilo 120y coupe?

925KG X 2.5 = 2312.5


is this correct or was this all crap

thanks guys for ya info and help
just had a look so is this it
engine size (cc)1809x2.5=4522.5 and that is legal??
sorry weight x 2.5 =
