I see your RB32 and I raise you an RB34:

FACEPALM!

If only there was more than one RB34 thread on this forum...

Will be interesting to compare This kit to Nittos kit.

It would be very interesting to compare. Nitto's 3.2l kit costs a lot more than the spool 3.4 atm. Has anyone actually compared any of the spool products alongside the nitto items to compare quality and watnot?

yea thats what i was getting at... it probably comes from the same bread shop like 90% of the gear on the market

which means price war!

Apologies I thought you were unaware of the rb34 kit and had just noticed the rb32 kit.

Why would you choose the rb32 over the rb34? Cheaper? Rev higher?

I presume its cheaper. The longer the stroke the higher the piston speed at a given rpm so I guess the 32 is less stressed.

Well side by side won't tell you much other than the sizing/weight with things like rods etc.

Need to actually properly test it, install it, drive it etc.

Unfortunately there are little results around even after a bit of time :(

Totally understand where you're coming from but the cost of manufacturing a 91mm crank compared to a 94mm crank is so small it's not worth mentioning. I'd take a gamble and say the pricing will be the same as the 3.4 RRP. Any cheaper is ripping himself off, as long as it's cheaper than Nitto he shouldn't have a drama selling them

as r31nismoid said unless there is back to back comparission the only differences would be price,

i still am yet to personally see an rb34 spool kit, seen plenty of nitto r32 (probably as nitto is local in sydney and spool is qld i think)

though the customers have said they bought the 90mm stroke as they think the 95mm stroke would be an over stroke for their application,

which is along the lines of what r33_racer was saying, all depends on what the motor is going to be used for will depend on which crank is best

plus spool appear to use cp pistons

nitto use JE/SRP

(which the cp workers used to work at JE/SRP before starting their own company, so end of the day same piston quality)

in theroy the benifits/ differences i can notice other then the srokes;

nitto cranks have slight knife edging and the rods with big end oil squirters

spool cranks from what ive seen in pictures/ read are fully counter weighted aka gives the crank more throw (encourages it throw itself in the rotating directing)

I think it's more a case of there were a few NITTO strokers getting around early on. No doubt via reduced pricing for market penetration by a few places etc.

Yet the SPOOL RB34 results really haven't been seen anywhere or in at least volume of half a dozen type thing.

Understand the in-house goes first as you can't really sell something that's going to mince itself due to poor materials or something, but it's taking really long?

once again never seen a jun stroker crank, which after googling looks like a full counter weighted crank too (bout all i can tell)

seen a few normal 26 and N1 26 cranks, 2.8 HKS cranks, fair few nothing special rb30 cranks and nitto 3.2 cranks, would like to see more variety but all depends on our cutomers, plus once the machining is done most the time we rarely hear of any results

    • 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.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
