from 3lt to 4.2lt

[Hunty]

Mate go the 4.2 you won't regret it. There is a big deifference between a 3l and a 4.2.
You can get alot of power out of a 4.2 if you spend a bit of money.

Fity as for getting the tacho to pick up I believe you need to get a whole new dash cluster.
I know the 2.8 one still works but the 3l ones are different.
You will also need to change your throttle cable over as it will be computerized and 4.2 is just a
Straight cable.

Thanks Hunty. I think the gq pedal and cable will fit the gu all the bolts and holes look to be right.

I guess a rd28 or td42 dash from a gu will get it working, I might play around with building an electronic box between the tacho and pick up. I enjoy that sort of thing.

If you search in google for killa kustom kables there is a bloke in qld that changes the looms over to suit the td42 and its all plug and play, im waiting for mine to arrive any day now. It still uses the 3l computer and runs everything!

[Hunty]

In the 2.8 most of the computer stuf is for emissions stuff and was all cut out and only the basic wires were left. It was going to cost $800 to send it to that bloke for him to cut it all out.
I would assume that the 3l is mainly emissions stuff to so I you changed the instrument cluster to a 4.2 or 2.8 an you know a bit about wiring or you know somebody you will save yourself money and time.

Did mine last year.
Td42 bolts straight up to zd30 auto box.
Recommend factory new engine mount brackets. There is a really good thread on the other patrol forum with photos started by Bexi.
I used a GQ Engine which was already turbo intercooled.
Sold zd30 for $3k so cost about $15 to get it all done incl engine.

I did read Bexi's thread on the other forum before it got infected. I may have to buy an apple to read it again.

same in Qld, except that if the engine you are putting in was not a factory turbo, we need a blue platewith code for the turbo and a separate code for the intercooler.
Mine is a 2000 model with a 1991 silver top engine, which was not even turboed back then.
blue plate cost me $150 plus two hours sitting around at Qld Transport so that a pencil pusher could come out and read the engine number?
He was too fat to see over the mud guard so i had to read it out to him??????? What a joke!

[Hunty]

Owen was that $150 for the intercooler and turbo?

And why does the intercooler have to mod plated? just because its not factory?

[PattyWgnOwen]

The 2000 model was not produced with an intercooler, but I think if the engine number corresponds to an engine that was factory fitted with an intercooler you might not need the mod plate for it?
It would not surprise me that the intercooler needs a mod plate anyway just because td42ti was not an option in 2000.
$150 was for one mod plate - i have heard some things require more paperwork, and may therefore be more expensive to plate.
On my car, the one mod plate has two codes on it, and I have seen mod plates on say HQ holdens with up to a dozen codes.
you would be surprised what needs a mod plate, including removal of the back seats to install drawers.

edit - the $150 was the plate fee. Qld transport did not charge me a fee, but I did get a bill for the extra rego to bring it from a 4 cyl to a 6 cyl.

vicroads have told me a engineers certificate is not needed if 4.2t was availble in your model

Could be wrong.... but you will find that even if it was available in that year model, you will still need it engineered as its a modification to your vehicle.
