Hi Guys,

3 very quick questions for you,

1) can the R32 RB25DE ECU be rechipped (as the RB20DET one can?)

2) if i add a turbo to an R32 RB25DE head, assuming it can be remapped to suit, will i need anything else electrically to support the turbo (apart from a boost controller)

3) is the r32 rb25de gearbox the same as the rb20det box?

thanks guys

i believe that the R33 rb25de gearbox is similar to the R32 RB20DET 5 speed

still not sure on the rechipping of the R32 RB25DE computer, turns out ours was an R33 one, so that was out..

we will probably either go for an Rb20det computer (i have the loom, just need the ECU and all the sensors), or just go aftermarket with the RB25DE loom that came with the engine

haha you sound in a similar situation to me.

I have the RB25DE loom and sensors on the engine which came like that, but while in Japan I have picked up an RB20DET ECU.

Hopefully the looms are close enough and I think only one sensor may be different.

When I get back i will take photos and try and compare notes with anyone who is helpful enough with the opposite of what I have.

yep, been there :D

by comparing the two, the signals seem to be very similar, a couple are different.. Have a read of the RB30DET thread, i asked the same questions and the consensus seemed to be that you HAVE to use the same sensors as the ECU you are using..

from memory the two connectors for the ECU's are different too..

i would love for that to be wrong ;)

      RB26DETT Sketchy boost mod?

      By ARB26 · Posted

      I might be way off the mark here.. there must be a T junction under the manifold. That takes manifold pressure through a check valve prior to the T, one side splits out to this bleed off orifice, the other straight to the wastegate actuators.

      RB26DETT Sketchy boost mod?

      By ARB26 · Posted

      Carrying out some engine due diligence before my first drive in a 260RS that has been in storage for 10+ years, and found two lines that are susposed to be plumbed into the boost control solenoid. One of the lines (the wastegate boost supply line) to actuate the gates, had a bolt in one end blocking it. The other line (main boost signal line) from the very rear of the intake manifold (RB26DETT) and runs up to the boost controller had this pill in the end of it as seen in photos. Other than the obvious (T28 Ceramic turbos might well be cooked)  Can anyone shed any light on if there is any validity at all with this mod, bleeding a constant fixed rate of manifold boost pressure off through this 3mm hole?  Is it deliberate?  Was this a 90s Jap mod done to RB26's? Or has someone just fitted this without any idea of what happens to ceramic T28s if they are not gate controlled?

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
