Hi mate, do you have the exhaust for sale? If so, what are specs? Cheers

I happen to be doing a bit of wiring work today on my HCR coupe manual, and this plug is disconnected - everything in the car functions perfectly. I suspect it may be for auto transmission variants, but could be wrong. Good luck. Edit - I mean the large plug in your first post.

Cool. Cheers for the info! Have you had it on a dyno, and are you running more than 0.5bar max? Keep me updated when you know more i'm very interested.

Has anybody used one of these on an rb20 before? I'm almost keen to give one a shot due to the bolt-on/standard look factor. http://www.ebay.com.au/itm/Upgrade-Turbocharger-RB20DET-RB25DET-w-Stage-3-Turbine-68mm-Comp-450BHP-/281199995072?pt=AU_Car_Parts_Accessories&hash=item4178d368c0 Would I expect it to behave similarly to a TD06-20g, maybe slightly slower to come on?

Hey mate, what exhaust is on the car?

Maybe try 2.32? I'm game to try it on the weekend, will let you know how it goes. In the meantime i'll find you the link. https://www.trust-power.com/03electric/Ultimate232_setup.EXE

Running 2.30 with no hassles except for random richness when cold start maps are on. Intermittently it'll drop to ~9:1 afr's and miss for 2 secs, then return to normal. No idea why. Everything else works perfectly fine. Out of curiosity i jumped on trust jap site and saw v2.32 is available. Will try it out on the weekend.

Photos of the rear (handbrake section) would help. It's definitely a windback piston, some calipers do have a screw in the rear for winding back. Give the piston face a few taps with a hammer too, it helps to free them up alot of the time.

Is this an RB20 or 25 at all? Sounds like the hydraulic lifters may have bled down due to sitting for too long. Just keep cranking, for no more than about 20secs at a time without letting the starter cool.

Injector latency? Wait, sorry.. so is it still random stalling at idle?

Is this an auto trans? If so, the auto trans cooler/heat exchanger inside the radiator may have split. Check the auto trans fluid inside the trans for traces of water too (just incase). If it has split, you have 2 options: replacement radiator, or block off the stock trans cooler outlets by linking with a piece of hose and run an external cooler instead. You can buy bottles of cooling system oil remover (500ml from memory) which you add to the cooling system to break down the oil and flush it away. Works really well! If none of this applies to you, please disregard

It won't always be logged. Only if its way out of range, or open circuit.

MAF can definitely give this sort of symptom too. I would swap it with a known working one before pulling apart too much else in the car.

TRW Lucas GP600 is also reasonable, at $65 for 1L

It's not intermittent, and not a common thing to have with these sort of calipers, so i wouldn't have thought that. I will double check though - it wouldnt hurt, cheers.
