JDM EJ20 N/A

[evolutionmovement]

Anyone know anything about them? I remember seeing these from importers for cheap a few years ago. I wasn't interested for a 3k lbs. car, but for a 1.5k lbs. car I am. I can't seem to find much info on them, I guess because nobody else is interested in putting one in a 3k+ lbs. car either. Wiring doesn't matter as long as I'd only buy it with the harness and there's nothing to integrate when I'm wiring from scratch. What I'm wondering is if they can run on US gas. I want the car to be aircraft-like, but not to the point where I have to go to an airfield to refuel.

If you're running a standalone w/ your own tuning, I don't see why you couldn't make it work.

[evolutionmovement]

No, stock wiring and ECU. I used to see these for under a grand with transmission. I don't know if they still exist that cheap, but I was curious to know more about them before I bothered looking. I don't really need the power, so cheap and reliable is important. Even a regular N/A EJ22 will move out with 1500 lbs. or less to move. I like the idea of the higher rpms and the novelty of the JDM EJ20, though.

I think one of our Dutch members put a similiar engine in his Legacy. Here's his thread with some pics: http://bbs.legacycentral.org/viewtopic.php?p=281942

It was an EJ20D with 150hp and 4 cam shafts.

Thanks. I saw that, but from what I read, there was a Japanese market EJ20 with 190 HP that I was wondering more about. Probably runs on ridiculous octane. The 150 HP version isn't enough of a bump over an EJ22, especially a later one, to bother.

If you're worried about bothering, why do so w/ locating an EJ20 that has hard-to-find replacement parts when the EJ22e is common, cheap, and makes more than enough tq's to 'move out', as you stated? Also, w/ a standalone and a little tuning time, more power and efficiency are sure to be found. If you're building the entire vehicle from the ground up, why stop at the engine management?

8k rpm and slightly smaller displacement. I don't actually want all the torque. I don't see the point in spending another several thousand dollars on EM and fighting tuning when the OEM tuning will be better and essentially free. I don't want more performance from the engine as that comes from the chassis and body—I want reliable and fuel efficient. If I was going to throw that much money at the engine, I'd just buy a crashed S2000 like I really want and not have to worry about fitting a wide engine between the frame rails (which are higher than on a regular car. And lower, but I'd clear those as they'd be underneath). I'll probably end up with an EJ22 anyway (if it fits without requiring me to fuck my design up to do it), but was curious about this version.

I'm only putting antiquated gas engine technology in it at all because batteries aren't cheap or good enough for my purposes yet and I can't figure out how to duplicate the claimed running by Tesla of an electric Pierce Arrow on "ether" (and I'm not quite ready to abandon a manual transmission). I'm designing and building an entire car nearly unlike anything else on the road. I need to rethink even things like rear defrost and get creative with lighting (and still have to cross my fingers when I present it to the inspector), never mind luxuries like making the interior look nice and all the little details so that this looks like a prototype from a coachbuilder and not something built in a shed by an eccentric nutcase (whatever the truth may be), so I really don't want to waste my valuable time and money tuning, especially when it doesn't hold any interest for me at all.

I don't really want to build the friggin' thing in the first place—I would rather pay someone to do it for me and to do it fast (and then do three other designs I have). Opposite to a lot of people who restore and work on cars for fun, beyond small details that can be done on any schedule, I mostly hate having to build projects—I like the results. Building my designs, when it's even possible for me to do that, are a necessary evil because I lack the money to pay someone else to do them (though I'll find someone else to build the chassis as I don't weld and lack the patience for all the necessary, critical, alignments). I have more ideas than I'll ever have money, time, or patience (and not just cars). I'm hoping I'll at least enjoy forming the alloy body panels and the little details I have planned.

I take it, nobody knows about this particular animal?

I agree with the notion that using an existing and proven power train is a good idea, then your primary focus can be on the design of the vehicle itself.

No, I don't know much about this particular animal, but I'd like to know more about the dual stage intake manifold though. Anybody know how that works?

We get a lot of JDM vehicles in New Zealand, yet I've never encountered a 190hp EJ20 n/a in all the years I've been around Subaru's. I'd have seriously considered one instead of a JDM EJ20 turbo if I'd been aware of such an animal. Which model came with the 190hp option?

[evolutionmovement]

According to Wikepedia, the BL/BP JDM Legacy, but I've only otherwise read about it a couple times on message boards. According to that, it's a DOHC with AVCS.

[kimokalihi]

Yeah I doubt it's 190hp. That's pretty crazy. Why would they make a 190 hp NA 2.0 and then give us a 2.2 turbo with only 160hp?

Doesn't make any sense.

[evolutionmovement]

Introduced 2003 as a performance variant of the Legacy. As for the differences in markets—I don't understand the why, but if you look at imported engines for sale, the JDM engines have all kinds of visual differences alone, some of which seem unnecessary or pointlessly different when compared to the final power numbers vs. the USDM. Perhaps there's a tax penalty on engines over 2.0L? Looking at the specs, I don't see why they didn't use the USDM 2.2 over some of their 2.0s. With the higher CRs they'll get better mileage, but would require much higher octane fuel. Maybe there are market peculiarities in regards to higher octane pricing, I don't know.

Finally found some info on the beast in question—190 HP @ 7100 rpm and 144 lbs/ft @ 4400, which sounds beautiful to me for my intended recipient. Except for one insurmountable problem until direct injection comes along—11.5 CR! Yeah, I don't think my usual gasoline suppliers are going to be able to work with that. Oh well. It was a nice, if brief, daydream.
