ok, just got engine rebuilt, put it in, started it up... worked fine, but wouldnt rev over 2500...

took it for a drive, still wont go over 2500, but has heaps of power under that.

checked afm, all sensors.. everything, found out that the tps is broken.. the top plug has been snapped and the top terminal is missing... but the car still idles.

now it wont start easily, and is leaking coolant out of the bellhousing for seemingly no reason...

the coolant leak doesnt bother me cos its not much, but limp mode is driving me crazy.

how do i get my ecu into diag mode so it can tell me why its in limp?

i have no led's in the ecu, and its a RB25DET out of an auto stagea(im assuming), put into a manual r32 GTS-4

the ecu has this written on it - [PCMNR-030] [C1] [6Y01]

ANY help would be appreciated

cheers :)

OK, well i sorted it... not sure how but this is what i did..

changed the spark plugs (the old ones were as black as the ace of spades)

adjusted the tps so that it sensed the accelerator a little bit earlier

advances the CAS timing a touch

somehow it now goes over 2500rpm...

not sure why the car fixed itself but it did

wierd...

      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.

      Duncan's V37.......race car?

      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.
