hey guys, im not sure if this should be under general Automotive discussion...if its in the wrong section please move it =]

anyways. was just wondering which one would be cheaper, a RB26dett R33 half cut, or a RB30 (R31?) + Gear box + RB26 top end .... planing on dumping it into a S130 project im working on....

or if theres any other alternatives please give me some advice.. thanks guys

I think the RB30 bottom end (no more than $300), RB26 cylinder head (2k complete), and gearbox (which one??) would work out cheaper.

I am pretty sure half cuts are around the 5k mark.

There is an RB30 subforum in the forced induction section on this forum.

a gtr half cut is bout a bit over 6k i think..not too sure... =S i thought about doing a rb25/30 but how much power would that be able to push out of it? and how much would it cost? =S

For R32 or R33/R34

You'd want a 33R half cut for that price, and that way you get the brakes which alone (resale) for ~1500 for the fronts if they are decent with rotors/pads etc.

Sell the dash, cooler and other bits and there is another 700-1k off

So if you dont use all the above its already ~3.5k ... which for a running 26, with loom, and the other lefts overs isnt too bad in my books.

25/30, if you do most of the work and do it right (forged pistons) you should be able to have a running motor for around 3k. If you are using fresh stock internals than a bit cheaper than that. (apparently they are good for 600rwhp) but rb30's have balancing issues so you would wanna get a decent harmonic balancer after you've balanced the whole block.

Im doing the exact thing at the moment.

    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
