Check the cables and the little geared mechanism between the switch and the tap to make sure there's no slop in there. Guys on ausubaru.com have used the VT/VX/VY heater tap - it's roughly the same shape but vacuum operated. I don't know how they've got around this vacuum operation but it'd be doable and I'm sure you'd have it nailed Cheers Bennie

I'm sure dad's got an RX7 carb from a rotarty 12B in the shed somewhere if you want to play with it - of course I'd have to talk with him about it first It seems that weber performance in Melbs has seen a bit of business recently - Tweety has just made a purchase there for his EA81 too... Cheers Bennie

You need to check out this fella's conversion for the suspension: https://www.facebook.com/photo.php?fbid=793968740631717&set=gm.10152389533988973&type=1&theater I hope that link works... Basically a forester floor pan and firewall welded into a brumby/BRAT body... Cheers Bennie

I've looked up part numbers of kits on rockauto, then dropped this number on fleabay motors in the US to see what comes up. Had I have known about importexperts I would have purchased through them. The kit turned out to be really good, I was happy - and it cost me about half of what I could get a kit here in Oz for, including postage! Cheers Bennie

Frankenmotor: 2.5<2.2 heads single port vs dual ports

I believe swapping to rollers makes it an interference engine. Correct me if I'm wrong pls. Cheers Bennie -
EA81 running on one side of engine only

Oh yeah, the engine has been rebuilt at some stage too - the pistons are flat tops without any subaru factory marks that I'm used to seeing on EA82s. Cheers Bennie -

Maybe I got that wrong then - I thought they were all hydro, the imports were solid lifters... Yeah I didn't think the 14 litres of water and oil I drained out was important to the issue at hand: Still going: It had apparently sat for 6 months with this mix in the engine. I thought it'd be a dead engine due to over heating and a severely blown head gasket - but it turned out to be a popped welch plug: And this is what I found once the heads were off: Hmmm... yummy! So it's taken me six months to get it from the clean up after finding the above on the engine stand to being on the floor ready to go in. It then took me a week to get it back in and running - on all four pots Cheers Bennie -

Hydraulic lifter. I backed off the rocker arms on the side in question until I could make a tiny tapping noise with the lifter arm on the valve stem. Fired up beautifully - got a little bit of lifter tick (to be expected) but it runs and I'm very happy with that. No smoke after the initial burn off of the oil we put in the cylinder - much much less than what came out when I first fired it up! Now to replace the water pump, ball joints, engine and gearbox mounts, sort out why the interior fan, radio and thermo fans aren't working, replace rear diff seals, replace damaged front guard and clean the interior then it's off for a road worthy. Can't wait for that day! Thanks for the suggestions guys. Hopefully this thread might help someone else out if they use the search function. Cheers Bennie -
Diff output stubs can be swapped for the EJ units. Problem is pulling the EA 5spd PT gearboxes apart is a PITA to do. Worth the effort in my opinion - you can use off the shelf drive shafts then. It's also a good time to drop a front LSD in there I kind of find this funny as in Australia we're using adaptor plates to mate EJ engines into the EA vehicles. I only know of one EA gearbox being fitted into an EJ vehicle and that was a FT4wd locking centre diff unit to a H6 - went well until the incorrect use of the centre diff wore it out (unlocked on sand). Otherwise it went very well! Cheers Bennie

I don't have the gear to do a compression test until I can steal dad's unit. The head gaskets and inlet manifold gaskets have all been replaced. The downside to this engine is that when I got it the guy said "it just stopped dead on the side of the road one day" and had sat like that for 6 months - engine was full of water as a welch plug had let go. I thought it was a head gasket. The engine was pulled down to a short block, all the muck cleaned out and the surface rust removed with some sand paper. Bores *looked* good after this, cylinder 1 was the worst with some tiny pitting at the top of the cylinder, but it's one of the working cylinders. Hence my thought that I need to look at the valves on the non working side of the engine. This engine could be a loss, but I want to look at every possibility before I come to that decision and decide on what to do after that. Cheers Bennie -
G'day all, I've finally got my red targa brumby's engine to fire up - but it's only running on one side of the engine (driver's side to the US crew). I've checked plugs and leads, swapped the working side to the non working side without any change, swapped a good set of leads in without change. When I remove plugs 2 & 4 there's no change in it's operation. Would I be correct in thinking that I need to play with the valve clearances? Cheers Bennie

My L series wagon has the same issue - but in the heat! It's the instrument cluster for some reason... The brumby with the factory 6 gauge instrument cluster doesn't have this issue... Cheers Bennie

Phiz have you looked into the stock carb from the ford 6 cylinders? They look like they'd fit well, they're dime a dozen. Apart from that I don't really know much more on them (as you know I'm pro EFI - but understand what you're trying to achieve!). It'll be great once you get it up and running - then the real fun beings! Cheers Bennie

I would say that the best EA81 blower set up would be with EFI - either a set of turbo heads running the turbo wiring or even the EA82 MPFI wiring. Or go with the SPFI setup. You would need to watch the richness of the mixture in the exhaust gases for a while to make sure it wasn't leaning out when on boost. Tweety (on here and ausubaru.com) did a draw through setup with a side draft weber I think they were - datsun units I believe. A draw through unit will eventually eat the teflon coating from the supercharger fins/blades/whatever you want to call them - some say this is not an issue, but who knows... Tweety did have issues with his fuel economy - too high for his liking plus the block started having blow by issues as you could imagine. Shoving a blower on a well used engine that's been built for NA will show up all sorts of blow by issues. Ultimately you need to build up an engine specifically for boost. I'm pretty sure he loved the power the supercharger provided though. Now he's managed to source a SPFI unit in Oz and is running that - after a lot of fine tuning and troubleshooting he's finally seeing the smooth running and simple start that he's been chasing. There was one in QLD that I've seen on facebook as well - I think that one's been parted out, but it showed a good setup that fitted under the bonnet... Cheers Bennie

If you've managed to bend both rear wheels to a new angle you've "done things well". Just not the type of well that you're after! Depending on what you find it could be time for a new rear subframe. But you could've just bent both rear swing arms - still a huge effort to do that! Cheers Bennie

RWD with a locking center diff?
el_freddo replied to SubaruWagon87's topic in Old Gen.: 80's GL/DL/XT/Loyales...
If you're going to destroy a gearbox like this, send it my way and I'll sort you out with a PT4wd gearbox. The part time gearbox would be stronger for this application, but as with all subaru gearboxes, the rear output shaft gears are the weak link in running RWD. That gearbox you've got is not something to weld up like that! Save a good gearbox and get a run of the mill PT4wd box Cheers Bennie -
G'day mate, To hook up the fans to make them ECU controlled you need to use plug F47, wire 17. This is an earth switched wire, same as the stock EA radiator thermo switch. You can wire it straight into that factory wiring if you've got your fans hooked into that, just make sure it's NOT on the earth wire side of the radiator switch With the ECU controlling the thermo fans they should switch on and off as needed. If they're on all the time you need a new temp sensor - the brown plug, two wire unit on the coolant crossover pipe under the intake manifold - it's a PITA to get to! I'm still working on my radiator situation too. Your setup looks neat - I personally wouldn't worry about it, after having seen the pics I think it's neat and effective. If you don't want 5 lug anymore "feel free" to ship the rear end setup to me!! Cheers Bennie

I wouldn't say this thread is old... I'm yet to get the stock EA81 going - then I'll mess around with the MPFI setup. Does anyone know if the crank pulley on the EA81T is a direct swap with an EA82 unit? I'm thinking it's not as the EA81 crank pulley from memory also runs on the oil seal... I'm keen to get my hands onto one of these and the bracket set for the EA82 AC/alternator setup - or does the stock EA82 unit bolt straight on? More questions! Cheers Bennie

All good, we've got the message. While this is not an autocad file it's certainly one way of producing your own adaptor plate. Cheers Bennie

The 2nd EA to EJ swap, trials and tribulations.
el_freddo replied to Scooner's topic in Subaru Retrofitting
Top effort mate - especially having a little man child to deal with too! Hope you get many years of happy trouble free motoring from this conversion! Regards Bennie -
Sorry I forget that you don't have the same sort of constraints that we do over here with chassis rail modifications! For example, to drop an EJ20G into a Brat you need an engineer's report for the chassis modifications (some are hesitant to sign off) - but you also need one for the engine anyway. Same goes for any EJ in and MY or L series... Cheers Bennie

I made a set of shims from two shims used in the steering column of old holdens - these still needed to be ground down a fair bit. If you had some flat bar steel 4 or 5mm thick you could grind yourself a set - just takes time. Be sure to drill the hole first, otherwise drilling on an angle after grinding will be fun... I've never had an issue with engine mounts, but I've always run these shims too. I'm currently running the EA82 engine mounts in the front hole of the EJ engine mount plate and have sleeved the gearbox crossmember holes for the gearbox mounts. This effectively pushes my drive train back about 15-20mm; so far that I've found the back of the sump rubs on the engine crossmember (now that I've got the engine out) - no noise there though. I've heard to avoid the round engine mounts like the plague for an EJ into an L series/MY as they don't last long. Cheers Bennie

Yes they do. The EA81s between the US and Australia are pretty much the same thing - emissions could be slightly different but the main bulk of parts are interchangeable. Further to this have you tried out ausubi for some local knowledge? Cheers Bennie
