Is a "EA82 carby" to a "EA82 MPFI" a worthwhile upgrade?

I was having a look on wikipedia,
the power and torque figures of the different EA82's.

Torque is about the same, ranging from 101-103 ft lbs, so nearly negligible.
Horsepower ranges from 84 hp for the carby, 90 hp for "single point efi" and 97 hp for "multipoint efi"

97 hp vs. 84 hp? That's a power increase of 15%.

I would assume with that kind of power increase,
100 km/h would feel the same in 5th at cruise,
but downshifting to 4th should feel better.

The question you should be asking is about how much extra work is involved between the EA82T conversion and the EJ conversion.

The answer will be not much. But the EA turbo will physically drop in if you've got the turbo engine crossmember. The wiring will be the fun bit again.

IMO.. no

All that effort for very little gain but if you got a EFI wreck for bugger all, your EA82 carby engine was shot and had the spare time, then I'd say go for it. And when that EA82 EFI engine gives up the ghost, then fit the EJ in.

LT65 has a EA82 MPFI that he is yanking out of his Brumby.
I thought if nobody wants it it might be a nice, cheap upgrade.
I think his motor is a lot younger than mine... just over 1/2 the clicks on the odo my L Series has?

BUT my EA82 still lives... so it's not worth the hassle yet?

Decisions, decisions.

His EA82 is mated to a 4-speed (auto?) though...
Would that pose a challenge for me since I have the 5-speed manual trans?

I had a look on the max torque and power specs for EA82T's and EJ22's...

It looks like the EJ22 makes more power
with the only possible advantage for the EA82T is the torque peak is 1000rpm lower.

I've talked to a few people who've had EA82T's and they reckoned the fuel economy was pretty bad.
TOONGA claims 9L/100 km in his EJ22 (carby

) powered Brumby... that's better than my EA82!

But I'm open to learning the merits of an EA82T...
even if it's only seat-of-the-pants.
Can you tell me more about them?

How cheap is an early EJ22 powered AWD Lib ?

I liked mine. Also on reflection spent too much and money on it. And it always needed a spanner on it.

Given that mechcanics are not your thing, rather than trying to turn an L into a Lib, buy a Liberty and enjoy the power and smoother, well everything.

My latest acquisition was surprisingly smooth and torquey and quieter due to its efi air filter me thinks , it was EA82 mpfi NA , nicer to drive than the carbys I have driven eve though the rest of the L wagon was a bucket!

My EA82T AWD 5 speed does dead on 10 l per 100km
At least EA82 mpfi will fit to your car without any other mods like radiator, tail shaft, mounts adaptor plates etc, but still see a lot of work in convert carby wiring to mpfi.
I agree with Pauls 'suggestion' of AWD EJ car itself - must be some wisdom there

Sorry! I read it as a query about the EA82T...

Trust me, the EJ conversion is the easiest way to go rather than an NA MPFI conversion, I've been there and done that

Wish I knew about the EJ conversion before I did that

I just brought a D/R AWD Gen 1 Series 2 in what I consider fairly good nick (usual burgundy red clear coat fade on roof and bonnet) with 300,000kms on the clock and with 6 months rego for $600

But there is just something about an L that is just unexplainable

Really no issue being that it was a auto but the main worry (IMO) is the trouble you go through to make it EFI, then you might as well put a later model (and more parts available) engine in there.

I'd keep your car stock for now and if you find a EFI model (like Bennie did) for $100 then grab that and keep all the EFI bits spare for when your engine dies.

This is just my opinion and can't really say too much as you know what I'm doing with my L but remember, I have the parts, tools and workshop to play in and my L is not my daily.

EFI Ls should be pretty cheap to buy , thats the easiest way .

I think I've heard EJ22's can be pretty cheap to come by... cheaper than other EJ's?

My L Series is no longer needed as a daily driver.

I could probably put it out of service for a few weeks and use a work ute instead, easily.

So the EA82 MPFI might be cheaper and a little easier...
it's still at least half the hassle it'd be to drop in an EJ22?

If that's the case, I'd rather hold out for the EJ22.
I still think I prefer the 4wd to AWD and a manual trans to auto.
I'm getting pretty skillful at quick, accurate shifts, so offroading is getting easier.
I'd prefer to mate an EJ to my current drivetrain, if practical and possible.

L Series instead of a Liberty?

IMHO the L Series has a lot more style,
I think it's the tight turning circle and shorter overall length
(making it fit more places offroad?) is why I'll always prefer an L Series to Liberty.
it's big enough on the inside yet 8 inches shorter body length
with something like 3-5 feet shorter turning circle.
Isn't it also a few hundred pounds lighter too?

Considering the EA82 MPFI conversion is about 80% of the work to do an EJ22 then you may as well go straight for an EJ22. In that sense i would not call it a worthwhile upgrade.

absolutely.

doing a motor swap from a gutless motor to a just as gutless motor is pointless.

EJ22s can be picked up for chips these days and you can continue to use your current gearbox and running gear.

Ruuning now the ej25, the three EJ22 libs of my mates feel gutless. Put a little extra and get a ej25:)

Okay, I didn't realise it would be so much work.

An EJ-something sounds ideal.

Hmm... tempting.

What kind of fuel economy do you get with the EJ25?

My fuel economy with EA82 I consider mediocre at best... 10 L/100 km usually.
Probably most annoying about this is my distance to empty from a full tank.
I usually have to fill before I reach 500 km on the odo.
