Outer Limits 4x4 Board

If I want to do a V8 conversion into a 89 Patrol what are the rules using a pre 89 motor compared to a post 89 motor and I don't really do enough miles to warrant LPG or diesel.

What if I used a 350 SB Chev block or import crate engine that was aftermarket & made post 89?

Thinking of Rochester Quadrajet or injection, Holden is a possibility, and I would probably be happy with a 304, or 327, I have a light vehicle, so 350 isn't a necessesity, but may be cheaper depending on if I go new or S/H

Holden has plenty of support for s/h & aftermarket, possibly more than Chev, it's just Chev is older generation donk.

new engines i'm quit sure have to apply with the emission controls ?

If it's not an aussie spec engine then my expectation is that it would have to be emissions tested unless it's on LPG.

I'd say so too, but what years spec's, 89 or the date of manufacture?

The latest ADR's must be met, whether it's the cars or the motors

don't worry getting it passed is never an issue. i had a lt1 in a 85 bundera quad and ulp no cats side pipes straight through boxes and i drove it into qld transport for number inspection

This is because queensland transport will just refer all responsibility in the event of an accident to the engineer who certified the engine transplant.

If we were thinking the emission gear caused the accident I suppose yes, doubtful though. I suppose if it was too loud or smokey they could defect it anyway.

emissions probably wont cause an accident

but failing to upgrade your brakes, etc etc, all things that come with different engine transplant criterias.

I think there is a line in the QLD regs that states that replacement engines must be the same age or newer than the date of manufacture of the vehicle.

I have heard a few times that old (V8) engines fitted to newer vehicles but run on LPG, that was apparently a way of getting past emissions/engine age requirements.

This might be the rule I was thinking of, wonder if it would count for a 350 Chev that was made after the 89 Patrol compared to a secondhand identical block made before hand.

this is correct

if its a 2006 motor in a 1989 car, it must comply to 2006 adr's

if its a 1926 motor in a 1989 car, it must comply to 1989 adr's (is adr's plural?)

The benchmark for emissions is based on the engine manufacturers measurements, and aftermarket mods which may bring emissions down to an acceptable level will need to be confirmed by your engineer (ie he needs to sign off to say that the emissions are met).

It would be best to speak to your engineer as to what you can do do get your pre 1989 engine to the 1989 requirements. Its likely that he has done just such a thing previously (approved an old engine to newer ADR specs). Im thinking ICV's would do this exact thing all the time (hotrods etc).
