yeh i think its got a replacement as i can only see a vacuum line goin from the wastegate to the turbo. also there is a switch in the cabin and when it is pressed it drops revs or puts them higher... depends which way you look at it. what would that be for?

cheers

Is it an Auto. Some Autos have a switch which i am not sure what it is for. somethin live over drive. it is used when driving on highways and when pressed it drops to a lower gear i think. not sure though

no its not an auto. looks aftermarket. not too sure what it is then lol

get pics of both the switch and the actuator.

you say that the hose from the actuator just goes to the turbo. do you mean it is only very short and goes to a nipple on the compressor housing? if so then the turbo isn't the stock one either as the stock turbo doesn't have a nipple on the compressor housing.

as for the switch making the revs drop, it would have to be something that is adding extra load as someone said. how much does it drop it by? only 100 or 200rpm? could possibly be an aircon switch if the stock one is dead. maybe try seeing where the wires go

      All this talk about fuel and fancy ECUs, meanwhile my poor old R32 has neither.... When the ignition is turned on, should there be power running o the fuel pump constantly or just for the few seconds it usually takes to prime the pump? About to go have another look at it, have watched some YouTube vids on how to use a  multimeter and looked at some wiring diagrams but really have NFI what I'm looking for because electricity is invisible

      Yuh....but weren't all the supertourers, except maybe the Audis, FWD? I don't recall any of the others being AWD.

      They ran them in Oz Super Tourers too https://www.supertouringregister.com/register/vehicle/212/ (I'm so old I remember racing with Matthew Fox) They ran them in Oz Super Tourers too https://www.supertouringregister.com/register/vehicle/212/ (I'm so old I remember racing with Matthew Fox)

      Yeah, hard to find and a pain in the ass to change with the transverse engine. I’ve worked on a GTiR before and it’s not a job I’d ever want to do again. theres a company in South Africa that makes RS3 gearbox adaptors for the AWD SR20 including gearbox mounts, so I could modernise it and go a dual clutch with paddles. For now tho, it ticks all the boxes. Super cheap, can throw the kids and their junk in the back, and SR20 that I can turbo cheaply, a CVT that’s not a dog’s breakfast like the V35, and has 80% interchangeable parts with stuff I can source from the wreckers cheaply…. But it’s still unique. I love the wagon back of the Autech version. It’s cheap enough that I can buy another stock manual FWD Primera with SR20VE, swap the gearbox to the N15 pulsar short gear ratio box, swap out the brakes to the R32 ones I pulled off my 32, register it on club plates and take it racing. $1300 shipping from NZ. Heaps of parts and aftermarket builders for transverse SR20’s in NZ.
