Bit reluctant to respond if you’re not hanging around

 

Still waiting mate, doing some of my own research but would appreciate other people's experience in this matter as my first engine swap to be engineered

 

Basically it needs to comply with ADRs and have emissions etc at least as good as the host vehicle.
Don’t hack at the firewall and be careful- or get advice on - welding anything to the chassis in terms of engine mounts.

 

The issue I'm having is that it is going to need an LA2 certifications as the 190kw of the barra exceeds the above 20% of the 129kw 4.2L petrol stock engine of the 1997 patrols so I need brake test which is $5k and a few other tests done which is going to blow my cost out of the water for what I was expecting for the certification

 

Maybe think laterally.
Turbo the TB and you will have more power than the Barra. 230kw from memory at 16-18psi.
No conversion needed.

 

Also thinking- you’ve done 90% of the conversion? Where are you currently at? Changed diff ratios and gearbox?

 

I had a brake test done for engineering years ago. It was $400. They have a stopping bed the roll the car onto at a certain speed and hit the brakes. They do a bunch of tests, front brakes disconnected, rear brakes disconnected, brake booster disconnected, handbrake.
