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.ravensblade-impreza.com/modifications/misc/models/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.

Edit: HTML mistake

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"

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....

My skepticism is confirmed, then.

i have some original sti parts for sale (including ecu), check my posting in the for sale...

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:lol: My ACT clutch is on back order:( Good excuse to lighten the flywheel, though:D

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:)

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...






SLR-

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?????????

Jeremy Siwek
JSiwek@scu.edu

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 :D on my grill...especially since my car is only 2700 lbs!

What is BAIC?

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:confused:

Originally posted by suby2point5rs

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?! :confused:

Mike

he has another project he has been working on

Details! :p

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

22B is the 2.2 liter...

http://www.subarucy.com/home/showroom/special.html and www.22b.com

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?:confused: 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 :D on your grill! (Sorry, I love to wax poetic about my Scooby!:p)

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.:devil: 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.

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

Just to be EXTRA clear, according to the MRT book, GC8 regular sti's have the same exact tranny as a normal wrx. RA's have the stronger tranny.

That's good to know, I actually posted on the MRT forums about that this week, but am still looking for a definitive answer. I believe both the Type R and RA have hardened gears. Was MRT refering only to Australian spec STi's having non-hardened gears? I know the Aus-spec STi Ver 6 is 4.444, but apparently it doesn't have stronger gears like a Type R/RA.

I spent $3700 for a complete '94 WRX front clip, as I wanted to have as much of the original car as possible. You can look at my mods here: http://www.subarureview.com/bio.php?name=annointed and do the math if you want to get an idea of how much tuning a 320 hp GC8 will run, not counting labor...fwiw, to get to my next target of 375 bhp (280 hp atw), I'll have to shell out about a grand for the 18G compressor wheel upgrade and injectors.

The beauty of it is that you end up with a very lightweight car (2700 lbs in my case) that is unusual, crazy fast and totally unique...and you can easily make it sleeper or aggressive, depending on your taste...the average person, even theives, and police, don't give a GC8 sleeper Scooby a second look in this country.

I posted the tranny numbers in this thead:

http://forums.i-club.com/forums/showthread.php?s=&threadid=208834

I don't have the book anymore, but I recall ALL of the AU trannies having 4.444 diff's, suprisingly enough.

I belive STi Ver 3/4 RA's/Type R's, and 22B's all had the same tranny - TY752VB5CA.

www.i-speedusa.com has done numerous swaps and I would definitely recommend them to anyone that was looking to get "A little" more power out of their subie.

~Evan

geez, i would hope this forum would make people wanna do these conversions themselves and post helpful information on how to do so, but i guess if you can't i-speed is the way to go.

Yeah, doing a conversion on your own is something that I would never undertake. Although when done by yourself (And with the help of a couple of buddies of course when needed) it is probably one of the most rewarding things that I can think of. I could probably get the engine in and out of the car but I would never be able to do even a half-ass job on the wiring.

I was just adding i-speed to the list for a group of guys that can offer lots of advice and maybe guide someone that needed some help. But they do offer very nice turn-key solutions.

the twin turbo will not fit in a US GC8 don't even try... much props if you get it to work... a guy in AZ already made a custom bolt on TT set up for the EJ25

mark

The EJ20 twin turbo was only available in the Legacy B4 RSK and associated cars, and is actually slower than the single turbo versions. Twin turbocharging is used only to smooth out the throttle response and power delivery to create a more "luxury" ride.

Here's a place to buy an ej20 front clip


I live in moscow Idaho and I have a friend (who owns a bussines called xessiv motorsports) who can get ej20 front clips for much less than any I've seen. He can also get pretty much any other parts too. I just ordered one for a slammin deal. He orders them from a place that will replace anything that is broken when you get it, as the engines have about 30,000 miles on them (I know this because my friend troy's had a broken oil pan and they shipped him one right away.) It comes with the ecu, tranny etc. Pretty much the whole front half of the car. His website is http://xessiv.com/customerrides/customerrides.htm. It is not a really fancy website because it is a local business but he is a really nice guy who will help out as much as possible. After I am done with my engine swap my car should be up on his website as well. Give him an e-mail and he should be able to get you a qoute for any engine or part you want. I know he does price matching.

I aslo really could use some help on wiring and how to tackle this huge job. Maybe someone has a few tips.

ok so you have now crosss posted this in to two forums .. both in reallly old threads

breaking one rule treading closely on a second .. stop dooing this

I need to know how hard it will be to swap in the twin turbo engine. i need to know ALL parts and modifications to make this work. i am completely clueless!!!! Help!!!!!!

did you notice nobody has posted in this thread in 4 years? and you shouldn't ask your own questions in someone elses thread. post your own thread or do a search.
