I want JDM WRX!

Default For those who went JDM.

Im looking at buying a complete JDM WRX. However I have another thread about all that and its not my issue for this one (newbies forum if youd like to offer more help).

I want to know the downsides of the JDM parts.

Do you find it hard to maintain these cars/parts?

How is wear and tear on them?

If something breaks, do you have to order from Japan for a replacement?

What sort of parts are compatible with US?

Can US mechanics generally work on these fine?



I do search, I do lurk, and Ive been reading these boards for a while. Im just trying to pull all the info together I can to see if I should try to go through with this deal.

There is a lot of parts compatibility across the model ranges regardless of which generation WRX you get. If you are getting a newer (MY00+) JDM swap, a lot of USDM WRX parts will work. For earlier cars, it's a mishmash of Ej18 and Ej22T parts that fix most issues that arise.
Some things either need to come out of Japan or the UK. One item in particular that comes to mind is head gaskets. There are also some North America vendors like LaChutes, Rallispec, Gruppe-S, Fineline, and a number of other who keep some stock of JDM parts on hand.

As far as mechanics? most dealership mechanics are too book trained to be willing to touch such a "strange" car. But there are lots of independents who know that these cars are just like legos and will be more than happy to work on your car. Post a thread in your regional forum to find out who in your area will do that kind of work. Eastcoastswappers is one group of people that comes to mind of the top of my head. And Rallispec is in NJ...

Like Matt said, there are a lot of basic, integral parts that are interchangeable between the different models. For example, the power steering pump on my EJ20g was busted, and I was able to use the one from my old EJ25. The pump itself was exactly the same, although I did have to take them both completely apart and swap over the resevoir and a couple other components in order for it to fit right. I haven't encountered any other problems so far that required OEM replacement parts.

Also as Matt said, don't expect very much help from dealerships. Your best bet would be to find a performance shop that has a lot of Subaru experience. Chances are, they'll take interest in your car since it's relatively rare, which means they'll be more willing to help you out. If they're any good, they'll be able to use a little improvisation and ingenuity to figure out a solution for almost any problem that comes up.

Talking Jdm motors

I have an ej20g and have only had trouble with the power steering pump so far (knock on wood). I beat on the car everywhere I go and I feel like the motor is just made better the my 02 wrx. The smoothness and sound is more consistent and extra power doesn't hurt either.

As for parts, luckily there is a local shop called outback motorsports that has really helped me out. They have at least twenty JDM long blocks at their shop ranging from single to twin turbo motors most of which are all older. They use the motors for sandrails so they don't need most of small parts on the motor because they do custom set-ups. They are more than fair with their pricing so if you go with an early version motor look them up. My JDM up pipe cracked and they sold me a new powdercoated one for 60 bucks.

As for replacement parts that need to be brand new (belts, pumps, gaskets) most of the parts are the same as one of the usdm parts you just need to take them with you and find the corresponding motor. ( I took a blown radiator hose to the dealership and ended up with an early legacy turbo hose.)

My only suggestion is that if you go with an older model replace all of the hoses, water pump, oil pump, timing belt and cam seals before you drop the motor in that way you get a fresh start with the motor. My motor was off one tooth on each of the cam gears on the right side so I'm glad I freshened up the front of the motor.

Good luck

Is there a USDM crossover radiator for a JDM 1994 EJ20G?

Some downsides:
The motor is old so expect some issues.
The headgasket will probably give up sooner or later.
The original rad will be at or near its end.
The coils on the Gs often fail and are fairly hard to source.
The seals should all be replaced.
The A/C system is difficult to get working correctly.
Cruise control is also a problem.

It's a really good idea to have access to a shop that knows what they are doing. You should also have $3k on standby when something major breaks.

Go version 7 and newer and you find parts are almost 100% interchangeable with our usdm wrx counterpart of the same MY!
Not to mention the engines are in pretty much new condition and will offer great reliability, especially for the high power output!

I went with version 7 motor and tranny. I was able to get tons of small little parts for WRX for the motor, and all the transmission parts are the same as USDM STI.

Can't you use the steering pump and AC from the USDM body?

I'm just in the middle planning stage for a JDM swap and was planning on using the PS pump, AC, and alternator original to the body.

Is that a no-go?

cjfike, you can use USDM STI power steering pump. I have it on my V7 motor. AC compressor you need to use from your RS motor. It fits, and its the only one that would connect to you hoses.

only US parts i have left are: wiper motors, a/c condensor, PS rack, horn, wiper jug, and interior bits. and my 98 V4 isn't that old considering the mileage on it. finding parts hasn't been bad...yet.
