As stated I'm looking for some one to tell me what this turbo is. Unfortunately I can't give you a photo.

It's an APEXI AX53B70! I found it on a variable valve RB25 at the local wrecker who have no idea of it's value and was thinking of getting it

Does anyone know? I suspect the ID numbers represent the A/R's, so a 53/70 turbo

It has an adjustable wastegate actuator rod and the standard dump with internal wastegate, Braided oil and coolant hoses.

I suspect p25 as thats the only listing for rb20/25's. They are roughly equivalent to 2530s so should be a good little unit on an rb20.

If its under 800 and you are willing to take a bit of a punt on it's condition (as with all second hand wrecker turbos) then grab it.

    • 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 BSP male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSP reducing bush?
    • 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.
    • ..this is the current state of that port. I appreciate the info help (and the link to the Earls thing @Duncan). Though going by that it seems like 1/4 then BSP'ing it and using a bush may work. I don't know where I'd be remote mounting the pressure sender... to... exactly. I assume the idea here is that any vibration is taken up by the semiflexible/flexible hose itself instead of it leveraging against the block directly. I want to believe a stronger, steel bush/adapter would work, but I don't know if that is engineeringly sound or just wishful thinking given the stupendous implications of a leak/failure in this spot. What are the real world risks of dissimilar metals here? It's a 6061 Aluminum block, and I'm talking brass or steel or SS adapters/things.
