Are aircooled motors kept in bajas because they're better or just easier?

Hola, Como Estas?

Well guys, I am looking to dropping a subaru ej(20 likely) into the butt of my 63 rag top. I am aware that buying a donor subaru and taking my time pulling the ecu and harness then pulling the engine and that slow methodical process. Then I would have a heartless donor car to dispose of as well as another process of the install and wiring and blah, blah, blah...

So!, my question is simply. Would there be any real problem with pulling the engine and blowing off all that wiring BS and just carbureting the sucker? I mean really, its bad enough swapping that good(cough) ole aircooled 1600 out for a water cooled quirkless engine but why-oh-why do I need the extra 5 pounds of control equipment in my baja?

Q&A's greatly appreciated.

Some talk about using an MSD II ignition ??

There is one with a distributor on the left head running off the cam gear

And one with a megajolt...

I'll try to find links.

edit--> Links:

megajolt


Distributer

I would be more for the distributed option because if I'm running carbs instead of the ecu why not wash my hands of electronic ignition all together.

Problem though.....where to find a distributor for the ej?

I have been researching what is currently being done with Corvair engines in aircraft. They have come a long way. Some people are taking Subaru engines that have to use a gear reduction prop drive out and installing Corvairs! The Corvair has so much low end power they don't need gear reduction. The Corvair conversion is lighter and MUCH smoother. You can get a core for as little as $350 and the replacement parts are CHEAP. Modern seals for the engine make them oil leak free. Reverse rotation cams and essential conversion parts are availible from Clarks and other places. You can get Pertronix ignition for the stock distributor and manifolds to run single two barrel or four barrel carbs. I have had to straighten out quite a few strange running issues on Subaru engines that are still running the factory ECU. Some replacement parts are only found at the dealer and are expensive. Aftermarket EFI system would be much better but that is more money.

Honestly, if your going to do all the work anyway, go with the ECU. Twisted Evil I have almost 1000 miles on mine and the exhaust is still clean inside. Runs super efficient and not a hiccup. Have you considered an ea-82 or the six cylinder version, they have distributers already. If done right you will not have problems. I'm running right now without speed sensor, without neutral switch or clutch switch and everything is fine and dandy. Went off road (hard) for two days, drove probably 45-50 miles street and I put 4.3 gallons of gas in it (running at 3500rpm cruise cause no fourth gear). And the self diagnostics point you right to the problem. No worrying about sticking needle valves, clogged jets, and altitude changes. Most of the problems you hear about are from those that don't completely understand the system. Or they have someone else install it and don't know a thing about it.

I think I am coming to that point. If it was as easy as buy the parts and secure and engine I would without hesitation because it just sounds neat to me and I would get a kick out of having an ej20 carb'd in a beetle.

Now my problem is that subaru's are premium in my area of socal and getting what I need from a salvage yard would be impossible. I've been looking at picking up a wrecked 2001-later impreza but I dont know how to get it from an insurance company.

Already a rudimentary kit available for this. It's a dual IDF carb install with Megajolt ignition control. Seems to work great! Cool

Let me see, you want to replace modern efficient EFI with old school poor efficiency carbs and doctor up "something" to work as ignition....

I convinced a friend (competitor) into putting a Subie with EFI (ripped from donor) into his Auto-X car and now instead of me beating him at each event, he beats me at the events........

I do not see a advantage or a performance gain here....

I agree, if you're gonna replace the VW air cooled motor at least make it count...I personally would do a 4.3L Chevy V6 conversion, gobs of torque and you can easily run a carb or EFI...tons of after market options and very reliable...all I'm saying is that if and when I was to ever replace the air cooled power plant I sure ain't gonna replace it with another 4 cylinder.

Where I am at, Subaru anything is premium so unless I drop a couple grand, I would be hard pressed to find a solid engine with ITS wiring harness. A carbureted EJ would be a fun thing to do and something that I would enjoy to have. so if there was a kit for it I would rather save the 1000 on an ecu and just make it run for fun. AGAIN:FUN.

After my first few days of searching I actually figured a 4L ford v6(I also own an explorer Twisted Evil ) but all that weight at the backend is something I would like to avoid. At one point I wanted to put in a smallblock v8 and set it up to tow, in case my girlfriends escape ever gets stuck but the thought of a 1800lb car pulling a 3600lb car up the cajon pass didnt seem very practical. Confused

Oh gosh I hope so, and thanks. The owner of the donor says that the car got side swiped and he just went ahead and bought another car figuring he would fix it someday but when I talked to him on the phone he didn't sound too bright. So I am hoping to get it for a steal. One question though, when you did your swap, how many miles were on the engine and did you every rebuild it?[/quote]

129,000. No rebuild. Doesn't burn any oil, but leaked like a siv. One of the valve covers had loose bolts (duh), but new valve cover gaskets took care of all but a few drips, and new "front" main seal and/or cam seals should take care of the rest.

I figured the engine is much better if I don't break it apart (I like to cut corners). If the short block goes, it's time for a replacement, that's what led me to the subaru in the first place.

We have Subaru's at work with 350,000 miles on them. Still run like a charm.

Carbs... Sounds like fun... almost. Shocked You will sure have a good story to tell.

Well, I hope not. I'm hoping to have a 166thousand mile new ej25 by the end of the week.

My mom had a old 80 somethin subi for YEARS. Put over 330 thousand on it and it still ran PERFECT. We ended up getting rid of it because it was soo old and she considered it an 'unsafe' vehicle for us kids. I guess the (only) lap belts and broken exhaust didnt have a chance against that 4wd system Sad
She got another subi. 200+ on this one already Smile They make good engines, just keep the efi.

Hey '63,

I got to thinking. You should approach the JB weld company and offer to build the carburated subaru with all JB weld. Have them send you a case of 100 tubes or more to build the manifolds, distributer mount, etc. You might get them to sponsor you. Then offer to tell your story and show off your ride for payback.

I've seen worse ideas; It just might work! Twisted Evil

This car was originally a project for me and my dad, but I wanted a baja and he wanted a lowrider so not much work got done on it.

He passed away August 19th from leukemia. I guarantee if he was alive to see me jumping back and forth on ebaymotors, craigslist, autotrader, and just about every forum looking for the right subbi, he would probably just go out in the garage and make it work just like you said.

And once it started running we would all laugh and applaud him.....

......then two weeks later he would just do it my way.lol

On a good note though, after a long day driving around with my mother, she has decided that she would get involved with the build, monetarily. It was her determination that if it was a me and dad project that dad would be buying stuff too, so she said she'll match what I put in for it. which means that I wont piss off my girlfriend each time I spend a few hundred dollars on parts.
