EJ22 to L Conversion queries

robdddd · Post by **robdddd** » Mon Jun 26, 2006 10:19 pm

Fuel Pump, rather than going the bosch option and surge tank I was thinking of two alternatives,

1. using the lib in tank fuelpump with a custom long range tank (possibly too expensive)

2. having never seen a lib fueltank...is it possible to fit/adapt to bolt into an L series wagon?

If the above is just stupid...anyone recommend where to buy a surgetank in Perth WA.

ECU wiring, I have started to install the wiring harness and ECU (previously Vidler's and then Seagull's), all going well but now looking at how to interface with the existing harness.........the Lib ECU came with the ignition, fuelpump relays etc, is it neccessary to run these or is it possible to use the existing ignition and starter circuits etc and simply power the ECU to run the fuel injection stuff??? I am on a steep leaarning curve here so may seam like a silly question...it is just that after looking at the amount of wiring on this harness compared to Subarino's harness on his website there must be more to simplify.

thanks for any advice.

I would be strongly inclined to use the relays - the engineers put them in for a reason. You should be able to tie in the EJ22 harness just by connecting to battery, ignition, starter and earth.

On the fuel side of things I doubt the Lib tank can be made to fit, pretty sure its a different shape all together. That said I haven't seen one for a while so I could be wrong.

I'd go the custom route, and I will be for my next EJ conversion. You're right, these surge tanks are nothing but a pain and it makes sense to have it all in the one tank. I was going to chat to a bloke over in Fremantle about it who I know has modded a standard Brumby tank. Wouldn't mind investigating how much it'd cost for a larger tank to be made from scratch too.

Don't stuff with the Ignition and fuel pump relays. Keep them in the loom. There is diodes in there that switch power between the two. The ECU also switches the pump and one primary safetly feature is the fact that the pump will turn off if there is an engine stall. Good in the case of an accident. You don't want fuel running at high pressure every where if some thing goes pear shaped.

Thanks for the advice, much apreciated!

Tim, If you find out about the tank conversion it would be interesting to see some comments posted.

in my EJ18 conversion I didn't use a surge tank. Just used the standard carby low pressure pump inline with the Bosch pump.

Fuel Tank -> Filter -> Std Pump -> Filter -> EFI-Pump -> EFI Filter -> engine

If you get the L-series MPFI fuel tank, it already comes baffled. This is a huge advantage over the carby ones, and has decent fuel pump.

robdddd... I can come over sometime and maybe help with your wiring if you get really stuck. I did my own EJ conversion and have been a helping hand with a few now and im sorta getting good at the harness wiring. I also have a few diagrams that a GREAT to use.

Secondly... just as a little note that may or may not help you. I have run an ej22 off the standard ea82 EFI high pressure pump and the car ran fine with no dramas.

Ohh i forgot to add... My wiring i did from scratch... all the relays had been removed when i got the harness so all my relays and engine test mode connectors are built into a main box that i made. This also houses the fuses for the EJ harness making it very very neat.

Theres nothing wrong with surge tanks if they are done right. My Series1 RX-7 has been running one for years. It sucks huge amounts of fuel, and I've had it flat stick full bost, sliding around corners for probably 20% of its total drive time (hell thats why I own it) without the slightest hint of fuel starvation. It's running a standard VL Turbo pump.

I would second Roger's suggestion though, just bolt in the MPFI tank. Also for an EJ22 I seriously doubt you will even need to upgrade the MPFI fuel pump either.

Dave,

Thanks for the advice and will keep you in mind if i get too stuck.......I was actually talking to Sunspares as they have previously been mentioned on this forum to strip down harnesses and tidy it all up, sounds like the guy who did it has moved on however they are tracking him down........they charge around $300 which may seem a lot, however I feel it is like buying an isurance policy so that some small electrical fault won't cause me grief on a camping trip up north with the wife!!!!!! Plus to quote someone else i don't want to make a mistake wiring it up and let the smoke out of the ECU.......or something like that.

On another matter, anyone after a puppy? We have 9 puppies ready to go in 6 weeks time, they are Spanador X Golden retriever. VERY CUTE

Just learnt how to post pics!

EA82 out (I have now bought my mates 2003 XS forester seen in the background.....leather seats and a sunroof...very nice!)

Lots of wires, adapter plate started (Started by Vidler), note the Outback headers didn't work..the exhaust ends up clashing with the crossmember.

Adapter Plate and new HD clutch

Going In EJ22 (from Seagull)

IN but still a long way to go!

Looking good mate.

So are you running the EA82 flywheel or an EJ one?

If its an EA82 flywheel, what method did you use to fit it to the EJ? Redrill & fill or Dremel?

If its an EJ flywheel, what clutch combination did you use?

Sorry for the questions, but I'm nearly at my wits end mounting my FWD 5 speed EJ box in my sedan...

the man you want to talk to about looms is Alan Butler (Al). I dont know anyone i would trust more with EJ electrics

his username on the rsliberty club forums is is Al [RSLC]

Thanks for the comments, it's great for guys like me getting help from those with more experience!

To answer some queries,

I went the EA flywheel and used a round file to slot most of the way and finished with the dremel (i found the hand file much quicker) My reason for slots over bigger holes was a personal theory that there is more likely to be even shear pressure on more bolts, whereas drilling larger holes may result in one or two bolts taking all the shear pressure...theory only!

My clutch is a modifiied EA done by a guy in Osborne Park (recomended by Vidler) I think he used a ford diaphragm to increase the pressure.

I recognise that pole in the middle of your shed !

What tools were used in the adaptor plate makings - jigsaw, dremel ?

I just learnt that engine and gearbox goes in as one - seeing is believing

robdddd · Post by **robdddd** » Thu Jul 06, 2006 10:31 pm

Jono,

Yep, i was shortening the span of teh beam over and didn't trust the connection of the beam to the house.

I was lucky to pick up the plate with the outside already cut out and only had to cut out the centre, drill and tap. Took half an hour on teh jig saw then used a sanding spindle on a drill to smooth out.

To locate the drill holes I used timber dowelling centres which you can purchase at any hardware shop, they are basically a short steel plug with a centering pin. Place one in each hole of the motor bellhousing line up the plate and tap with a hammer to transfer the centrepunch marks to your adapter plate. Then Drill and tap holes for the bolts and drill teh ones for the guide pins.

Engine and Gearbox in together would be much easier with two people. You need to remove the gearbox crossmember otherwise it won't go.

I will be adding some more photos to my website over the weekend and will then add the link on a future post.

What else do u have to do to get it running?

Offer still stands for doing any wiring... im starting to do some weekend cash jobs recently so i could be in for a few hours of wiring and cutting.

Dave,

I am about three or four weekends or so away from wiring, the rest of my life has put a temp hold on progress.

Would appreciate help when it comes to installing teh harness, still getting my head around how it all hooks in, also now realise I had overlooked how the alternater conects to existing L series harness.

List to do.

Wiring and ECU obviously

Back half of exhaust (also waiting for exhaust gaskets, no-one seems to stock them?)

Return fuel lines and install a Bosch pump in line with current pump (no surgetank at this stage)

Finish connecting up the AC hoses

Install Liberty accelerator cable

Radiator, just considering a reducer to get it to connect to tHe existing L radiator (at least till summer)

Modify the engine stay (think that is what you call it?)

Clean all the rubbish out of the car! ( found a fossilised bananna!)

Get a puncture repaired

Reconnect front axels (also replace one CV boot)

Looks like I also need to do something with teh two lines that must have gone to a charcoal canister.

Aircleaner and intake

Connect return line for power steering, bleed etc

and probably more that doesn't come to mind yet...like re-filling gearbox oil!

Take wife out to dinner to gain brownie points! (most important!)
