Just curious if all the non fly-by-wire EJ throttle body shafts are 8 mm D flat profile? Are EJ TPS the same?

Am I looking in wrong places? Cannot come up with this fellas wiring needs. He is a four pin unit and a Sensor type rather than the early Switch type. I guess this is reflected in a diagram cast into the plastic near the base of the pins. It is like an angle representation, so I guess it is the output That would make one pin sorted. The other pins would be for ECU 5V power (+) in, another for a ground/earth/ neg(-) connection. Got me what fourth pin would be. Early EA82 mpfi ran three pin TPSwitches on three plug ECUs, then with four plug ECUs went four pin TPSensors And then there is SPFI four pin sensors WHOA! Calling confusion here. Spiders ran four pin TPSensors and I know I have a four plug ECU Tourer and I think I only pulled a three pin TPSensor off it AND I also had something use only two pins of the three! Hand up if I confused you... Just tried to upload a pic and got 540 kB limit notice. Is that total contribution to the entire forum not just a post?

someone once managed to reproduce the TSB for this online out of curiosity, does anyone have a copy to stick up here please? It does matter to some of us that really need to stick with EA's for road transport requirements or have an engineer$ report

ala XT Vortex design to stream air only through radiator

that thing on RHS of trans in the side just above the pan is what you speak of (and yes, a vacuum line connected to manifold vac), cant recall correct service book name - only when I was pulling mine of 4WD 3AT did I realise it was loose, think it was fine thread screw in. Constructed a bit like oil GAUGE sender unit like a bell crimped over a base housing / Might explain why mine used to hang on to gears when flooring it, and really needed it to shift up. Have you cleaned all the usual crud off? I thought these were 17mm or 14mm hex for normal box wrench (open end spanner Aussie English)

I have had 85 GLTA, 87 Touring Wagon and 89 Girlie wagon. Girlie wagon? I said f u e l i e wagon !! Run EA82 in ute and Vortex so will keep an eye on it...don't disappoint hey?

I have USDM files that show EJ22 in the 1996 to 2001 Imps but all too different to my eye at first. may need a fresh look. Going to start from scratch and work out all the wires at engine bits like coil, injectors, sensors etc when I feel motivated. Got the other bits nearly finished to chuck in the Brumby to make sure it all works.

I have more to enter for the brown and grey engine plugs when the system allows me to shove more MB in this post. Great photo arrange skills too eh ? I got to look at factory manuals at a dealership and nothing in chapter 2.7 that I could find for ECU pinouts :( Going back when no real mechanics about to peruse chapter 6.3 to see if it has a wiring diagram with wire colours. Not urgent, but would love to have the stuff together before I need it. Shoot, after hearing the 8 intakes valves suck in air I think I want an EJ20 under the bonnet. Also may try the EA cases from DR to slap, yeah, "JUST" just slap around the AWD box and fit up behind an EA82 of some sort. The buggered AWD EA centre diff discovery has really peed me off Might be time to alter EJ AWD boxes to fit between EA82 in the EA81 Brumby bodies

Engine plugs

Sorry for upside down...

Continuing

I will start to load pics....

Bennie, what came to mind as we freeze our arses off yet another winter, of a guy on that goldfish bowl forum buster fb last US summer with a pic of his BRAT, with bonnet vents just on display saying he needed cooling advice. He was running in desert region, needed AC I think and demands on it were almost just too much. Despite later saying he didn't want to install bonnet vents, dunno why he put them in the pic. But then again, not everyone understands what I write sometimes either :) On those pesky pricey 6.75mm ID coolant bypass hoses to throttle bodies, I have done away with them and tapped and plugged the holes. just have the one from block to thermostat housing now

I was going to suggest EA81 twin cores as seems to be best for my EA82 in my EA81 bodied ute

stainless and electrolysis eh ? They are softer/weaker as well. My stainless not been in use yet/for long so far. Think they will need to be checked. And yep, copper grease is in my toolbox

Thanks for the quick responses gents. A closer look at the brown one - it has two pairs of fat wires in and out and a pair of scrawny coil/relay trigger wires so OK main power for whole cars electrics I was sort of thinking EA82 mpfi logic that relays together fuel and ignition so the white one might power up the ignition coils This car is a donor, but was an RX Impreza wagon GF8 with all the lights, bells and whistles you could ask for , just don't ask for a turbo :) Had AC, ABS, air bags . We in RHD AUDM region seem to have a problem because the great resources of files are USDM, and I am finding ECU wiring does not match by a long shot ( at my novice level) We continued to get the EJ20 in 99. Think the only EJ22 waS IN THE SPECIAL 2 DOOR wrx 22b, THEN EJ25s. I n my first look, got ten? mismatches from just the first plug I looked at ! The plugs are not easy to back probe, and for front probing will need to wrap a wire strand around DMM probe to get in just looking for wire continuity and maybe bundle and label

Can it be confirmed the threesome is fuel and ignition relays ? If so , which is which And the pair would be light relays?

And for the retainer end clip, mine broke recently and was able to flog a sexy yellow one from my 99 Impreza and fit once I enlarged the square hole on my Brumby

spider type feeds air in from the rear, flat type from the top side. Hmm, its with these old things you need to snap a few bolts, learn a few skills in thread repair, skin a few knuckles. Think it happens to most of us so you are not alone. positive side is that once I have fixed mine, never had same bolts threads corrode up on me as bad, ever in 20 years

dunno if it is going to help but on my 99 RX 2.0 Imprezza the two white wires both had charge voltage in them when running according to my mental notes made when engine was in and running

I haven't tried your suggestion. This is EA82 part into EA81 body. Only uses half the four bolt holes, so not much of a chassis stiffener but I guess it leaves things open for modification to add more holes, crush tubes and bolts through to the floor. Correct at this time the EA82 chassis stiffener holds nothing at all BUT it has got it off the to do list and to do shelf even though it advanced to the passengers footwell and as I said the intention is to add to it to stop a tailshaft yoke from popping out while in weight saving/friction reducing/fuel economy boost FWD mode - ie no tailshaft, rear diff, axles of hangers

Just run that gauge into your dash - it is an aftermarket one in my ute that reads zero, not a factory gauge !

The EA82 engineers slipped up and used the same centre-to-centre measure for the pressed metal trans tunnel brace as the EA81 auto trans cross member mounting points So....why not? I may adapt my 4WD as a FWD yoke holder when I pull the tailshaft trick

RHD clutch cable part numbers forEA81 up to 1982 is 737026021 83 on is 737026022

Maybe post up a photo of whole inlet manifold to jog memories. Someone may have one. I can think of two different manifolds - flat and spider. There were two versions of the flat for turbo in the vacuum hard lines and maybe throttle body too..but if you strip and swap. Has anyone ever had a broken bolt stud remover actually work? I throw mine away now when they turn up so not to tempt me I have replaced some boltwith stainless. Others get anti sieze grease everywhere. Those manifold to head bolts are the worst for rusting up in no thread area
