rb30

Russel Guest was doing things to RB30's a few years back for about $400 to give them some more poke.

He's in Melb at Guest 4wd.

Good Luck

You can fit full NISMO VL commodore kit on them...

I have a magazine here somewhere with one pumping out well over 200kw at the wheels....

But its cheaper to just fit a 350 Chev than waste the money on injection etc etc

Hi yebach,
With your rb30 have you tried the following for a start:
K & N air cleaner, extractors/exhaust, removing the air heating element/gauze in the plastic spacer under the carby as it restricts about 30% air flow (I got this one off EO 2 years ago and highly recommend it) ,a little more advance timing, removing the back seats if their not needed (saves weight),all the above mods each make a small improvement but together they make signifficant improvements to the car. My car feels like a different car to the one I bought and I havent done the exhaust yet! You can do a few other things also like porting and polishing the head, this and bigger valves should give signifficant gains....then theres always the VL turbo motor. You should check out nissan skyline forums, probably lots of info to be found. How much money do you want to spend? Dont forget Legal and insurance considerations re. engine transplants etc.

Buy yourself a rb20det motor and put the head and injection on your rb30, with a larger turbo. This will fix the power problems.
If, however, you want torque, have a look at the vh45de motor (out of the infinity in Japan)...v8, 32 valve, 4.5 litre 208kw std. There is mention of this conversion to a patrol if you search vh45de on the web.
There is one for sale on www.ozdat.com for $750.00

I've done a few things to ours, and with moderate success. I removed the pre-heater gauze constricting the carby and added a Genie Headers extractor system (made the biggest difference).

I have bought a spare RB-30 out of a VL from our local wreckers for $250 complete. its bottom end is shot, but I'm after the fuel injection. The reason that I bought the whole engine is that everything is there. Any little sensors or plugs or whatever I may need on the Patrol's engine will just come off the spare engine as a swap-in. I bought the ECU separately off eBay for $100 - including harness. Beware that if you find one, you should go for the one set up for manual gearboxes, as the auto one is a little different I hear. Not sure what, but you never know.....

Down the track I might get the turbo kit off a VL - if I can find one. I'm a little suspicious of the turbo though, as I don't think that it will be good off-road, as it develops its torque too high up in the rev range. I have a spare roots supercharger at home off a Toyota (Soarer I think) that is good for an engine of around 3 litre capacity. Castlemain Rod Shop does a kit for the RB-30 that includes a supercharger and all the mounts and stuff for a reasonable price, so I'll investigate that as well. Only problem is that you have to re-locate the power steering pump - no big deal I hope.
