If you need any info let me know I have done the conversion myself its pretty straight forward but there are a few things that you need to know. But I am guessing you have already done some research into it.
Here is a link to my build thread. ttp://www.patrol4x4.com/forum/members-nissan-patrols-19/finally-bought-my-gq-60938/ch

Disregard any info about the flywheel and starter motor that was posted in it as it didn't work and I am now just running the RB25 flywheel, clutch and starter motor.

It shouldnt take to long to do, if you have everything ready to go it can be done in a weekend,

No the rd28 starter motor will not work as the solinoid is in the wrong position and it fouls on the plenum. If your engine is from an auto car the ecu will be as well. I can pm you my number or there is a link to my website in my signature my phone number is on that.

No you cannot use the 2 together unless you can get the ring gear from the rb flywheel onto the rd flywheel as the teeth on the 2 are different.

Nothing has to be done to the gearbox the engine bolts straight to it. If you use an rb30 flywheel you will need a matching starter motor.

Is this the case with an rb30 (sorry to hijack). Will the rd28 gearbox bolt directly to it? So confusing after reading it will/it won't. I need a definitive answer as I am always scouring the net looking for an rb30 gearbox to buy as a spare due to rarity. If the rd28 box bolts up then I can stop stressing.

Yes rb30 is the same will bolt to gearbox
Sweet. I was going to get a gearbox shipped from QLD down here (VIC) at double the price of the gearbox because I thought the rd28 box wouldn't fit the rb30. Heaps of wreckers have the rd28 box ready to go.
