Subaru brumby conversion to ej22 HELP!

It is a personal preference, but the AWD box has never let me down on anything i'd call "moderate", It has stopped me a couple of times, but it was on seriously steep, loose hill climbs that everyone struggled on.
The big difference is in the on road manners, the AWD is so much nicer on road.

Please try not to get confused by what is a SOHC and DOHC. Above each cylinder there is no cam = pushrod, one cam = SOHC, or two cams= DOHC. The first letter denotes the number of cams which would be above the cylinder if it was in a vertical alignment, OHC is over head cam, as above each cylinder, not how many cams the motor has on different sets of heads because it is a boxer motor or a V8. How would you rescribe a radial motor with 12 cylinders?

If all you want is a little more power and torque then an EA81 with a carb in good condition, a distributor with good bushes, a decent service including valve clearances and maybe a better flowing exhaust will make it a decent little motor. I'd almost gaurantee the carb on your new car will be cactus and the distributor worn, two things that hugely affect its performance. Some people will pooh pooh the weber conversion, but i'm really happy with mine. I got 8.2l/100km on my last trip with 91 ron, and after having the valves adjusted this week the car has regained alot of torque that it was missing.

The EA81 is super simple, reliable and easy to maintain. An EJ conversion is a fair bit of work and while the results are fantastic, you also start to highlight other problems. The front-wheel drive is pretty average around town behind an EJ and the brakes really don't perform to the same standard as an EJ. Both of which are really difficult to address without a fair bit of effort, time and money. But stick with the EA81 and front wheel drive is fine and the brakes are definitely adequate.

I think most people compare the EJ to an EA in poor condition and i don't think thats quite a fair comparison. I think the best thing about an old car is the fact you can open the hood and everything is visible, simple, easy to get to and easy to understand. Why not keep it that way?

A radial engine...

Venom does bring up some great points about the EA engine - simple to maintain and with a bit of work (less than an EJ) it'll be sweet!

She's right mate, I just thought it odd to re-hash the SOHC/DOHC thing since it's been so long since the last post...

I am curently putting together the pieces to convert my Brumby to EJ20
Bought a wreck Brumby just for pannels n stuff.
Bought a MPFI L series Touring wagon to wreck. from that I will use.
5 speed HiLo, engine crossmember, possibly flywheel and clutch.
The interior also, seats carpet and center console.
Bought a N/A EJ202 that has done 103,000kms with ECU and wiring loom and 5 spped box but I don't think I will be using the 5 speed from this motor, I will make an adaptor plate to take the L series 5 speed HiLo box.
This is soooo much fun

That all depends on what you want to get from your brumby. Will you go offroad often, hit the "hard-core" stuff or just cruising around on a bumpy dirt road to see a few sites?

If you're going the hard core route and not driving it on the black top often then I'd look at the L series hi/lo range gearbox. If it's a daily and you'll be doing some soft/moderate offroading then look into a dual range AWD gearbox from a liberty then do the L series low range conversion (search, loads of write ups and links) or find a forester gearbox that has a decent low range from the factory.

You need to work out what you're going to use the brumby for, how much you want to spend and what parts you have available to keep the cost down.
