RB30DET convertion

[mud guts]

Hi guys i have a mate who has a RB30DET engine in a vl, he's spent a lot of money on this engine, 490HP worth, and wants to get off the tar and on the dirt and utilize this power. As i've read, the patrols came out with the RB30, what mounts will he need? Do you have to make an adapter for it, or are they available? What else should he Know?
Thanks Shane.

has he got a patrol with a rb30 in it?
if he has it will bolt straight in, if not he will need a rb30 gearbox and rb30 engine mounts, the chasis are the same. ive also heard of adaptors available to bolt the rb30 upto the 4.2 box, which may be a better option with the hp hes getting

So the deal would be to buy a patrol with the rb30, remove the engine, bolt his in, get a 4.2 box(auto or man?) and an adapter. Will that then bolt to the rb30's original transfer?
i think that makes sense.

I would suggest he buys a Patrol that had an RB30 fitted, if he can find one.

Should be a good conversion, except that low-down torque is required and the Patrol drivetrain is very heavy - lower transfer case gears would help heaps.

Also note that a fourby works at low speed with little airflow for a turbo/intercooler - engine temps in an already overpowered motor might be a problem.

already overpowered motor might be a problem

HUH!!!!
Only joking. Yes heat might be high, but still a lot of other turbos out there being used successfully. And yes gearing will have to be used, turbo wont make power without RPM.

twin cases work well on the rb30's. the std rb30 in the patrol has no problems staying cool, i had problems after fitting a set of thermos trying to get it to warm up. you might get the std box to hold up as long as you dont flog the crap out of it. the 3l and the 4.2l transfers are the same.
