If it's going into the GQ (assuming it's an rd28) an rb swap is quite easy in terms of bolting up. As the guys have said, early GQ's came out with carbied rb30's so the legalities of getting an rb engineered souldn't be too hard.

As for power... I own a nissan stagea, it has an rb25det neo and weighs 1900kg with 2 passengers and a bit of fluff. So when we go camping or I'm hauling around a heap of stuff, the 'ol wagon is well over 2T. It has a standard turbo, but has been re-tuned (using a nistune board in the stock ecu) with a bigger inter cooler and exhaust. For what it is, it hauls ass! With the turbo torque and awd I regularly scare the pants off hsv's and annoying bmw's. If I really get stuck, I also have 75hp of nitrous to switch on... but anyway.

I would find yourself a nice series 2 auto, stagea rb25det NEO front cut or engine package. Get a wiring diagram to help sort out what ecu wiring you keep and what body wiring from the stock ecu you can ditch. Get someone to install a nistune board into the ecu and run a manual r34 gtt map (if you're running a manual box behind it). Keep all the stock sensors, afm etc. Install a larger than factory intercooler, run a 3" exhaust at a minimum.

Most importantly, get the whole lot running with the stock turbo, afm and injectors... it's alot easier to fault find problems when everything is stock. Once you have it all up and running properly get it on a dyno and have the nistune board tuned to suit. You'll end up with about 130-140rwkw on 12 psi (don't try running anymore boost, you'll kill the turbo).

After that, 350hp.... Hypergear highflow/400-600cc injectors/Z32 AFM and a re-tune.

Install a surge tank with a bosch 044 and a whatever intank pump as a lift pump. The odd angles you get into in a 4WD you will need it.

Also, if you do crazy climbing or traversing, look at extending the sump or fitting an accusump.

Cheers

Justin

      Oh, I forgot too, all the multimedia stuff captured and sold through things like people playing Pokemon Go. Pokemon Go specifically, can actually be traced all the way back to a CIA investment company too. So yep, they're watching everything. Not to mention the new stuff where they've worked out how to use WiFi signals to be able to map occupants inside of a building. That one would be something that I see being more used in public/government buildings, as you need to understand the signals when the room has no one in it first. It's not as easy as Hollywood would like you to think it is.

      Followed ☺️ Assuming those are NEO rods, then at least 400kW all day.

      Great work! Give it a clean up with some Emery paper, and I'd run a thread die over the threads too to clean them up. It will make reinstall much easier, and also life easier for the next time it needs to come out.

      I'm not a fan of high humidity, it's one reason I don't mind being further inland out Ipswich, except the last 3 odd years, the drought broke, and it won't stop raining, which is making the humidity nearly unbearable when the rains are in during summer! For me, my body hates the cold, once the cold sets into my body, I'm totally screwed. I end up with severe muscle spasm in my back/shoulder muscles, and it feels like someone is trying to tear the muscles out. I have no issues with it getting stupid hot, so long as the humidity goes away. So the last 3 years as above, have been woeful! Ha ha. However, June 1st, and I'm only just converting from shorts and a tee, to long pants and a t shirt. And that's mainly as it's a bit wet and miserable and I wanted to work on a car.
