Sources for EJ20's and general conversion info

[annointed]

It seems like the past 3-6 months we've had a lot of interest in jspec/EJ20 convesions, so I'm starting this thread for sources I found when I was looking for my jspec WRX front clip. The list is by no means exhaustive, so feel free to add other sources to the list. Also, I cannot vouch for all of these sources...the first three are very solid, and I have also corresponded with and gained respect for Perrin Subaru Performance. I am not as familiar with the companies in the other links, so buyer beware.

Also, here's relevant info for conversion research (again, please feel free to follow up with more links, as mine are certainly not exhaustive):

Jspec WRX model codes and hp figures organized by year: http://www.northursalia.com/m...ls/models.html

Parts generally needed for an EJ20 conversion:
Engine, tranny, wiring harness, ecu, rear diff, turbo front crossmember. Half shafts, driveshaft, downpipe, fuel pump, brakes and suspension and all engine accessories are also nice to get, all of which is usually included with a front clip.

What's involved in a conversion:

Here's another source: http://www.infinitemotorsports.net/JDM%20Swaps.0.html

At the time of this posting they have the following front clip, which I find hard to believe:

"Subaru WRX STi EJ20 280HP JDM Subaru WRX STI EJ20 280HP Intercooled turbo
Includes: 6-speed transmission $5999 In Stock"

[XT6Wagon]

If you would look at thier pic closely, you would notice that its NOT a New Age STi engine and tranny. Lots of other things that bother me about that place too....

BTW, you'll probably want to upgrade to an aftermarket street/strip disc clutch (NOT a puck type race clutch), as I found out the hard way...the stock WRX clutch that came with my front clip held the torque for 1400 miles, and is slipping like a dog now My ACT clutch is on back order Good excuse to lighten the flywheel, though

I am glad to hear that other people are doing these conversions. Here in CA we (I-Speed USA) have done 3 US EJ20 into rs's (98,99 and 00). We have never needed/used the wrx tranny and we have always installed the swap with a lightned flywheel (jun, or such) and an ACT clutch. So far, all cars run fine ~4500miles on one car. It has been cleared as SMOG legal in CA too. Search BAIC for more info.
What we have found:
~40 TOTAL hours of labor (turn key project)

Breakdown
~17 hours of wiring (includes diassembly and reassembly of interior, old and new harness seperation, solding, shrink tubbing and heat gun...FUN)
~23 hours of dismantling and reassembly of everything else.

Of course there is a tad of fluff in there...but not much

EDIT : Thanks for catching my error MT

Cal's car is a 2000.

Hey Chris, been a while...
Know anyone that may be interested in taking my motor off my hands for one of your super duper rs/wrx morph projects? Avoid the salvage, nice and clean ~10K on it. Local BAIC head would be nice and convenient. Let me know if you run out of spares...

Yeah that puts me in the same boat. Trying to keep it a secret but doing a horrible job... I want to be the first EJ20 turbo swap into a US spec Legacy GT! I am actually looking for a nice STI WRX front clip, I want the entire engine/tranny/diffs/electronics, etc. The whole deal. Anyway, I'm in San Jose as well..... Christoph, any ideas?????????

I can't believe I didn't post who I got my front clip from! He's a Nissan guy, but he gets some EJ20 packages, too. His iclub name is apexwrx, but his name is Milo, out in southern(?) California. He's a very nice person to do business with, and the important thing is that my car now has over 4500 miles on it, and it's running stronger than ever, so he didn't scam me. Also, props go to Rallispec, who did a fanstastic job on the conversion.

Also, I took my beast to an AWD dyno yesterday, here's the results. I dont' have a scanner, so I can't post the graph just yet, but here's the stats:

I got 3 pulls in my hour. Each pull was in 3rd gear, boost controller set at 1.1 bar (15.95 psi). The car ended up being stronger than I expected, especially on the torque:

Max hp: 235.7 @ 6100 RPM
Max torque: 226.5 @ 5200 RPM

My mods are listed here: http://www.subarureview.com/bio.php?name=annointed

I'll have to post charts when I get to a scanner. The torque is cool. It rams right up to 220+ ft-lbs by 4000 rpms, falling back under 220 ft lbs at 5500 RPMs.

Based on 25% driveline loss that WRX's normally show, this puts me at 314 hp, 302 ft-lbs at the crank...no wonder everytime I mash the gas it makes a great big on my grill...especially since my car is only 2700 lbs!

Edit: How 'bout Bay Area Impreza Club! LOL! (seriously, I don't know why it took me that long to figure out)

[SuicidalLabRat]

Actually, I'm not looking to buy an ej20, but to sell the long block ( actually full assembly including all piping, up down, back and turbo ) out of my 02 rex.

I have a what maybe a stupid question to some of you guys but I was needing to know what an EJ20DE-TT is and what vehicle it originates from

This is a non-existant engine, although if you do an internet search, for some reason, there are people selling EJ20DET and EJ20DETT's. I've noticed this before. There is a seller on ebay who puts EJ20DET's up every couple months. EJ20 only refers to a Subaru engine, and DET is part of the name of several Nissan engines, IIRC. It doesn't exactly inspire my confidence when people refer to an EJ20 "DET" engine...

The following is true, AFAIK. It is based on Mike Shields' writings (SBD), as he is a long time Impreza tuner. The 4 types of EJ20 designations that I know of are EJ20G, EJ20K, EJ205, and EJ207. My older, closed deck engine is an EJ20G (not all EJ20G's are closed deck). EJ20G's were made until the 1997 model year. The EJ20K was a redesigned, open deck engine that STi Ver 3 and 4 came with. In fact, all WRX's in 1997 and 1998 are EJ20K's. EJ205, and EJ207 are the newest designations. EJ207 refers to Manual tranny cars, and EJ205 refers to automatic tranny cars. They apply to Ver 5 on (1999 and later).

If I missed anything, someone feel free to add to the list, or clarify/correct anything I said.

Just wondering, why are you selling your ej20?!

[christoph1371]

he has another project he has been working on

Annointed I would like to thank you for your informative post and I would like to ask you what is the engine in the 22B I have yet to find the exact answer to this question I would really like to know

[JSiwek]

22B is the 2.2 liter...

I also noticed u guys are gettin just EJ20s...if u really want power ur gonna want a STi tuned EJ20...which puts out like 278-280hp. THats what im looking for...if u guys have any info, let me know.
Peace

"just" an EJ20? I hear you on the STi part, of course I'd have loved to have an STi ver 4-6 RA powerplant in my ride, along with tranny (MRT believes the RA tranny is 30% stronger than stock WRX) and driveline, but the cost is VERY prohibitive.

Nevertheless, don't underestimate the power of a tuned, early EJ20 (TD05-16G and closed deck). My car flies...I've put nearly 11k miles on it now, and my jaw still drops open every time I open up the throttle, and the turbo puts me back...I'm amazed and terrified at the raw power this beast has when passing. Its top end is massive, and the turbo hit is thrilling. It's enough to put a huge on your grill! (Sorry, I love to wax poetic about my Scooby!)

And that's only with my car at ~320 bhp right now. Its soon to be ~375 once I swap out the small 16G compressor wheel for an 18G. (Forced Performance will do it for $429). After that, I'll probably add a 50 shot for the occasional strip days. When engine rebuilding time comes along (hopefully not for another 50-60k miles), I'll probably stroke the closed deck block, and shoot for ~500 bhp. Not too shabby.

So if you do it carefully, and do it right, you can get a lot out of the non-STi EJ20...and hopefully not break the bank. Early EJ20s came with a great turbo (TD05-16G) that flows over 500 cfm. The main STi benefit, IMO, is the tranny. I would say the main engine advantages are the heads (compared to early WRX heads) and forged pistons.

[SiNFuL-iMpReZa]

Whoa, heh. Nice car. No the EJ20 is exactly the same. The difference is that STi already tuned it up to 280hp for you..and i believe its not very expensive, id say 5-6grand. Unless thats expensive, i kinda figured thats the range for engine swaps these days. But you've already tuned ur engine to where i want mine. Im gettin it to 320hp(at the wheels tho, not the flywheel)...and then just leavin it there for rally. =). So ya, u just tuned it instead, which is awesome. How much did u pay the ej20? and how much for the mods to get it to 320hp? Sorry i didnt mean to hit a nerve, heh. Have any pics of your car? Alright, cool ride man.
Peace,
Galen
