Help Us! Need Rb30 Block Or Crankshaft!


Recommended Posts

How i know Nissan has 2 types of cylinders diameters( 20,24 and 25,26,30). Can we attach RB30 crankshaft to RB25 block? Intresting wherein the differences?

In our country we don't have RB30, many of people even not hear of this engine. So, intresting, can we install RB30 crankshaft in RB25 block.

Idea consist in the following:

-install RB30 crankshaft in RB25 (if its real? :)

-install custom-made coupler link and custom pistons ( We have manufacturability to bild this parts ^_^ Have somebody their size? ) In case of diffirent height block RB25-RB30, we can change it height, build some metall plate, following which we mount cylinders sleeves with need height. (

-as far as we know on RB30 block can mount head of a cylinder block from RB25DE,RB25DET,RB26DETT (This parts we have a lot =) )

-then, look-ahead terms, requisite us, manufacture intake and exhaust manifolds.


Hmm.. Did u know, that Russian company KAMAZ, produced disel trucks(PARIS-DAKAR winner) Their many parts fit under repair NISSAN SKYLINE =))

For example. KAMAZ turbocharger (twin scroll) can mount on instok RB20-25 exhaust manifold. Cost? Huh... 300 ~ 600 $USA (if u intresting that stuff, ask us :bunny: )

PS: We dont crazy, just have some crazy ideas

PS2: Sorry, my english very bad, if u dont understand anything, ask me! I'll try say it another way =)

    • Can't forget them. Have spent the better part of the last 2 years in Bunbury. Any longer and I would have to get one of each.
    • Hit it hard last night, was in the shed till 2:30am. Had to get everything ready to try fit engine today as neighbour is going away tomorrow. This happenned today      Was going smoothly, till it wasn't. Had to lower the sway bar, remove engine mounts to get the engine to its spot and then refit everything. Head drain also created some clearance issues but got there in the end. Some idiot put the drain return on the sump virtually where the engine mount is. Hose fits on but is less than ideal, going to have to revisit it and fit a 90° fitting. Had some hiccups last night too with getting the flywheel and gearbox on. Firstly forgot the sandwich plate, so had to remove clutch and flywheel again. Then gearbox went on smoothly but then realised new block has an alignment dowel in the same spot as gearbox. GB off again to remove said dowel. Cnut. Anyway, it's in now. AC and PS pumps refitted, tail shaft bolted up as well. Left to do is reconnect all harnesses and plugs. Looks like a big mess ATM. Fit dump pipe, radiator, shifter, intake piping and associated bits, air box fill, afluids and hopefully fire it up. Looks like couriers please has lost my break in oil again. Useless pricks. Looks like I'll just get whatever mineral oil is on special at super shit auto. Hopefully it will actually run after all this or I'm going to burn it, lol.
    • The genuine ones are a minimum of $95 each on amayama. Jesse Streeter just quoted me $190 each. I can get a set of 6 MSD for $470 on ebay.
    • You forgot jet ski's and neck tatts.
    • New Monroe OESpectrum shocks for the Honda have been ordered, the car actually handles well with the OEM shocks, but from pulling the wheels off for a good inspection of the brakes and bushings, the only issue I saw was that it still has the original shocks, and with 160k km on them they are well past their use by date Also, in other "kids these days" news, the airbox resonator is "in the bin", a little more induction noise down low free reving, but it sounds really good (growly) over 4k RPM on the road, worth while silly mod for 10 minutes of work and zero dollars Also the K&N filter for the OEM airbox arrived, whilst I didn't get it for performance, as it probably doesn't give any, it's more to save a few bucks replacing OEM filters every service, 3 filter changes and it has paid for itself I also picked up another 5 litres of HPR5 for another oil filter and some more engine flush, I'll give the last HPR5 and filter change 1k km to do it's thing then flush it all out again and stick the new stuff in, anal, but I feel it's always worth the effort when I get a "new old" car to really clean out its guts, and as the K series engines have a few internal mesh filter screens for the V-Tec thingie, as well as the usual one on the oil intake tube, it's preventative maintenance to keep the oily bits happy when I'm wringing it's neck The Bogan Cruise Ship might even come out from undercover this weekend for a cruise, weather permitting of course
