Hi all.

Just recieved my 4 x RB30 blocks today.

Is there any difference in the RB30 blocks? Aka. series 1 or series 2?

Are all the RB30 blocks the same from the factory?

How to tell a turbo block from a NA block?

And yes, this time I have searched. hehe. :P Could be I'm stupid at searching.

be easier if you took shots of the exhaust side of each block and the front face too.

then comments can be made and you can log them to each block

but yes, there are differnces in the turbo drain return, and front tensioner locations etc

This is a Turbo or Series II block

Besides the feed / return lines I am unaware of any other differences between a Series I and Series II block.

I believe the Turbo block used a higher flow oil pump but not 100% sure.

I also believe that the pistons in a turbo block have a dish, again, not 100% sure.

I wish I knew a place that sold cheap rb30's here! Every wreckers I go to wants over $300!!!

Feel like selling some N1GTR? lol

Thats funny, they came from Brissy :P

Sorry mate, not selling, they're all destined for mates cars.

I bought them from Spool imports :) He has been very very helpfull. My car is the only one with RB25DET here in denmark, and now its going to get a RB30DET instead. (200sx - s13)

The price is just fine, as i have sold the 3 others, so my own engine hasnt cost me a dime. :) But need to choose the one I want.

I will be changing pistons/rods/bearing etc. And use RB25DET oil/water pump.

The thing I'm after is if one block is more prefered than the other. (only block) If a turbo block is more suited for turbo in any kind over the NA block. (remember I will be changing pistons/rods/bearings etc)

Also, if I coat the pistons will the oil squrters be required to fit? (I know I have to drill and tap for them)

EDIT: Sorry for picture qaulity, its my cell camera. Hope you can see it good enough

Also. The crank pully. There are 3 different?!? How come is that? Only 2 are the same, the other 2 has different pullys. Some use a slotted pully, other doesnt, on there are size difference on diameter.

The RB25DET crank pully, will that fit the RB30 crank? (Im am not using power steering and AC in my car).

the 3rd pully on the crank is removable on the RB30 crank pully, which is good as i dont have any space infront of the engine for my water cooler. So a std RB30 crank pully with the 3rd pully bolted of, would that be good enough?

Cant find a place here in Denmark that can acid clean the block. How should I clean it out then? Spray my own acid cleaning agent on and wash it down? There is alot of "stuff" in water channels. Could I just use something to remove it? Like when cleaning a shower for limescale, I think its called.. (Water that builds up over time stuff, dont know the english word)

Thank you.

Right now I have begun to read the entire RB30 conversion thread. 346 pages.. damn. Have read the .pdf from Cobra30

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
