Lazer Posted May 16, 2007 Share Posted May 16, 2007 I currently have an Subaru Brat (1989) with an 6" lift and 29" superswampers. The car handles great offroad but it lacks power in the steep hills. Therefore I need a power uppgrade. I'm no stranger to swapping engines in a Subaru. I have installed an ej20t with drivetrain and everything into an xt turbo (needless to say.. it runs great) After that swap I realized that I have an spear engine (ea82t) that i have previously (1 year ago) rebuilt with forged piston's and new seals and bearings all round. I also have an megasquirt injection system that I've previously built for this engine I've been reading alot about the swap from an ea81 to an ej22 and I understand that this is the way to go if you want low rpm torqe. Below is an hp/torqe chart for the engines It doesn't seem to be that much difference at 2400ish rpm. But what's important to me is how they behave around 1000-1500rpm. ej22: 130@5600 137@2400 ea82t: 111@4800 134@2800 Does the turbo on the ea82t flow anything around 2400rpm at all?? If I go with the already available ea82t will it help me in any way in the hills? Link to comment Share on other sites More sharing options...
Numbchux Posted May 16, 2007 Share Posted May 16, 2007 they are pretty similar options...on paper.... BUT, wiring wise, both options will be pretty difficult. the EA82t will need room for the up-pipe. your brat doesn't have a notch in the crossmember. there are options in that department....but it's something to think about. and, the EJ22 is a much stronger motor, and the turbo invites a collection of things to go wrong (oil and coolant lines....seals, etc.). the EJ oil pump and sending unit are also in a much better place, not hanging down where things can smash them like the EA82. but, obviously, the EJ22 would require the sourcing of said motor and harness, and adapter plate for the tranny, etc. etc. etc. both are good options. personally, I'd sell off the EA82t and go EJ22.

Phizinza Posted May 17, 2007 Share Posted May 17, 2007 I too would sell the 82 and drop the 22 in. Similar amount of work with both. And if you want the unreliability of the 82t you can just boost the heck out of the 22 and you'll end up with more power while your there. BTW, you might of figured I don't really like EA82's.. :-\ Link to comment Share on other sites More sharing options...
suberdave Posted May 17, 2007 Share Posted May 17, 2007 this comeing from me, a guy that just swaped an EA82t out of my lifted wagon and put a EJ22 in. with the EA82T i went through clutches like crazy. it had no power below 3000 RPM so the turbo is spooled up. so when you let the clutch out it slips like crazy. the numbers may look close but its like compairing apples to bannas... the EJ has so much more power than the EAt could ever have at low RPMs. i also think that the EJ wiring is 10X easier that the EA wiring... -=Suberdave=- http://www.suberdave.com Link to comment Share on other sites More sharing options...
baccaruda Posted May 17, 2007 Share Posted May 17, 2007 all of the above plus parts are getting less and less common for the older engines. turbos require more maintenance on average, as well. Plus the EA82 in general requires more maintenance as it's got an overconvoluted timing belt design and other less efficient qualities. Also, would you rather run an EA82 closer to its max potential, or an EJ22 right in the middle of where it's comfortable? Link to comment Share on other sites More sharing options...

Lazer Posted May 17, 2007 Author Share Posted May 17, 2007 I'm also thinking about ignition. On the ea82t there's an distribuitor but on the ej22t there's multiple coil's In my mind the distribuitor is betther especialy if I want to run the megasquirt. Does anyone of you guys have an torque chart for the 2 engines up trough the power band?? Link to comment Share on other sites More sharing options...

Does anyone of you guys have an torque chart for the 2 engines up trough the power band?? If you are in norway you should be able to find a disty for your ej motor. Some of the ej series were available, outside of the us only, with distributors and carbs. Search for posts by monstaru and mattyB for some insight into this.

Numbchux Posted May 19, 2007 Share Posted May 19, 2007 ^ they're using Escort disty's. not subaru ones. I've never heard of any factory EJ subaru coming with a disty.... the fully electronic ignition is much better. simpler system, less to get wet when wheeling. and the ECU can make it spark anytime. infinitely tunable (with the right ECU...obviously the stock one has it's limits too, but stock for stock, the disty is not better). when wheeling with my EA82s, I had more troubles with a wet disty than anything else!

86BRATMAN Posted May 19, 2007 Share Posted May 19, 2007 The ej18 for sure did, as well as the ej15 and ej16 that we never saw. And I know I have read that the ej22 did as well. Link to comment Share on other sites More sharing options...

Matty B Posted May 22, 2007 Share Posted May 22, 2007 I am using a distributor from a Subaru Fiori (sherpa), it is my trigger for the megasquirt ECU. There are factory distys, EJ 16 and 18's I don't think there were 22's. The New Zealanders have the goods there. Search for Kiwi members maybe. Go the EJ22, fire it with a cheap distributor through your megasquirt. And post some pictures....scandyhooligans! Link to comment Share on other sites More sharing options...
