Putting A Stagea Rb25det Into My Hr32 Gts4 Auto

Has anyone had any experience on droping a Stagea RB25DET into a HR32 GTS4 Auto? (RB20DET bigends stuffed)

Sorry if this is really in the wrong section but I think SK hangs around here a lot :(

I am assuming it should virtually bolt up to the AWD GTR Style sump that I have left in place in the engine bay after removing the RB25 awd sump. If the oil pickup does not align I hope I can change the baffels or the pickup to suit.

The Wiring harness could be a problem area especially if I use a NEO (which I probably wont) as I want to use the standard rechipped ECU to drive it all and I dont know if it will just "Plug & Play".. now where have I heard that before? :) Thats right, its actually "Plug & PRAY!"

Anyone have any observations on this electrical nightmare :D

hey mate ive not done the conversion u speak of, but ive done a rb26 into the stagea and the stagea rb25 into a vl commodore so ive seen both engines. the stagea rb25 uses the same sump as the rb26 and i assume the exact same one as u have on your engine at the moment, just the diff has different ratios. That means the oil pickup will be fine, and fit without hassles also.

not sure about the wiring, as you could use a stagea rb25 ecu if u used the stagea auto box too, but im not sure what ecu to use with the rb20 box, though isnt the rb20 ecu's tunable and capable of running a rb25 no worries?

hope it helps abit

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.

      Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve.

      I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
