hi everyone i have a 74 bay auto 003 box standard 14 inch wheels with a EJ22.Car ,engine and auto are all in good condition.Conversion was done about 2 years ago and i am very happy with the way the car performs with the ej22.Fuel consumpsion is not what i was hoping.I know with the auto it revs pretty high but has anyone who has this conversion got some suggestions that i can do to improve the fuel consumption.By the way i drive to the speed limit i dont go out and flog the kombi.

Gday John, what's the actual mileage figures you are getting?
and how are you calculating it?

Most VW odometers don't turn accurately after 40 years and you actually drive more KMs than what it says.
always pays to verify by GPS if you haven;t already.

Did you end up getting the other issue sorted?

how many litre's does your tank hold etc?????

Our manual EJ22 bus gets 9.8l/100km at best. Running on 91 ULP

so you should be happy if you get about 400Ks a tank.??

I get 500 km easy a tank. Around town I fill up around 400 km

i have a standard vw kombi tank and am lucky to get around 330klm a tank around town.I dont have a gps to check what i am doing but i will try and get one

What year is your EJ22 engine ?
From my experience the early engines were very thirsty. I actually owned 6 Subaru's in a row over 15 years from new.
The first 1989 model 2.2l Liberty I would be looking for a fuel station after 400km. The next 93 model easily got 500 - 600km before looking for fuel. Then a couple of 2.5l Outbacks easily 700km all from the same size tank And thats when they were new.
The later engines were much more fuel efficient but I never bothered to calculate km/L as work payed for my fuel.
Hope this helps to put it into perspective - I would be happy with the power increase and the subaru engine is always going to be way more economical than the original engine.

hi karmin i bought the ej22 from a subaru workshop in murwullimbah and was told it was a series 1 liberty 89/91.The last time i fuelled up i put 42.2ltrs and got 315klm that was driving around town.If i am working it out right i am getting 13.4ltrs per 100 kim.Was hoping for around10ltrs per 100klm after i did the conversion.I am happy with the way car performs after the conversion but as i said before was hoping for better economy.Hoping to catch up with Joel soon so he can give it the once over.

what fuel are you using??
whats the revs at 100KPH ???
Do you have a cold air intake.
Is your motor a 20 year old motor that hasn't been rebuilt???
Each time you service it do you do the Subaru top end cleaner.????

Put taller tyres on your car or change the diff ratio to lower the revs....
Replace the O2 sensor,it's most likely the original one and as Ian said,use a fogging oil/top end cleaner to see if it performs better. No need to use it every service. HTH...

Hi john1960,
Well the series 1 ej22 certainly was the most thirsty even when new but that was in quite a heavy wagon with constant all wheel drive. You should be getting at least 10l/100km. Advice above is good if engine is old and a bit tired. High cruising rpm will also chew the gas. The auto certainly wouldnt be helpng.
I have a 94mod EJ 20 in a Bay Camper and getting 8-9L/100km. Does 2500rpm at 100km/hr

I have a 2L 6rib box which has albins 3rd & 4th. Not sure of ratios but will look it up. Bought the box which had been built to suit a Subie conversion.
I also run 16x7 Boxster alloys with 215/60 tyres. There is quite a big gap between 3rd and 4th but I've learnt to drive it a bit differently, but definitely worth the effortless highway cruising. Box would suit an engine with more torque better like an EZ30.

I sit on about 3k at 100kph in the split, but thats with a single side plate bug box.
Also get better fuel economy with the ej22 than i did with the old 1600, around 9ltrs per 100.

Thanks for all the feed back guys.I use normal unleaded fuel and dont have a tacho fitted so i dont know what revs i am doing.On purchase of the ej22 motor these things were done.New water pump,new thermostat,new crank seals,new cam seals,new timing belt and idlers.I have not heard of fogging oil top end cleaner.I will replace the O2 SENSOR and look into larger rims and tyres if that will make a difference with the revs. What size rims and tyres are other people using who run a ej22. I imagine to change diff ratios would be a expensive job paying someone to do at a workshop
