Im looking into putting a Turbo 350-400 manualised Auto transmission into my skyline. It wont be a direct fit so im going to need to buy an ADAPTOR PLATE or purchase a Modified Bell Housing to suit..

Ive done some ringing around and found at a few different places and the make these adaptors and housing but only to suit a RB30.. My question is would these adaptors for the rb30 fit onto an RB20..

Im thinking they may theretically since ppl do engine combos such as RB25/30 etc etc..

Just wondering if anybody would have any idea if these adapotors would be the same? Or atleast no of any buisness around the melbourne region that makes adaptors to suit RB20?

If it bolts to an RB30 then it will bolt to a 20/25/26 block too.

What auto's were in the VL's? T350's? you could probably find one that bolts straight up without needing an adapter plate..

na i also have a vl. they got a jatco box.. the non- turbo model cant handle much power at all and the turbo model is a tad better but not much..

So these adaptors that fit rb30 should defiently fit rb20?

I've had a 20 and 25t box on my RB20 and RB30 so yes, if it bolts to an RB30 it will bolt to an RB20 :banana:

Pretty sure people out there build those Jatco boxes pretty damn tough.. might want to look into it.

      The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!

      I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.

      Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.

      I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.
