Knichol Posted December 28, 2006 Share Posted December 28, 2006 Does anyone have some time and experience to answer a few JDM motor questions? I have a list of questions I would like to talk to someone about before i endeavor into a JDM swap... any takers? Link to comment Share on other sites More sharing options...

Subarutex Posted December 28, 2006 Share Posted December 28, 2006 If you want to keep in on the downlow, hit me up with a PM and I'll see what I can find out. Link to comment Share on other sites More sharing options...
Knichol Posted December 28, 2006 Author Share Posted December 28, 2006 Na, just didn't want to take up space, JDM motors what prep do they take? are they just a plug and play, meaning, lets say i have a 99 wrx, can i by a 99 wrx jdm motor and drop it in with out changing anything? Do things like senors, wiring harnesses, ecu, etc change? What all is involved with a JDM? If you want to keep in on the downlow, hit me up with a PM and I'll see what I can find out.

What all is involved with a JDM? first off if you live in washington than you dont have a 99 WRX. you may have a 99 impreza but unless its RHD its not a WRX. if you want to put a JDM WRX engine in an impreza you will have a lot of work ahead of you. give us more information on what you have and what you want to do and we can help with about anything you need. -=Suberdave=- http://www.suberdave.com Link to comment Share on other sites More sharing options...
Knichol Posted December 29, 2006 Author Share Posted December 29, 2006 Whatever year there was a WRX was made, I want to put a newer EJ motor in my 91 loyale which is not an impreza, i think... does that mean the swap is easier? Sorry i used a bad year as an example. Here more specifically is what I am looking for... lets say i have any JDM motor... what things would I have to do differently to place it in a US Subaru than if I got a wrecked US subaru and placed its motor in another US Subaru? first off if you live in washington than you dont have a 99 WRX. you may have a 99 impreza but unless its RHD its not a WRX. if you want to put a JDM WRX engine in an impreza you will have a lot of work ahead of you. give us more information on what you have and what you want to do and we can help with about anything you need. -=Suberdave=- www.suberdave.com Link to comment Share on other sites More sharing options...
Caboobaroo Posted December 29, 2006 Share Posted December 29, 2006 well you have to remember that JDM engines come from Japan, where the cars are RHD whereas our cars are LHD. Instead of like lets say, the port for the brake booster on the intake, being on the left side of the intake, it'll be on the right side of the intake, that sort of stuff. Nothing major from what I gather, just a few little things like that. Link to comment Share on other sites More sharing options...
nipper Posted December 29, 2006 Share Posted December 29, 2006 Well there is the nightmare that one is an OBDII (or the japanese equivilant) and the other is an OBDI. This can be a bunch of re wiring to get it to run correctly. nipper Link to comment Share on other sites More sharing options...
Knichol Posted December 29, 2006 Author Share Posted December 29, 2006 Thanks Caboobaroo, that is good to know, does this mean also things like fuel lines have switched sides? Is everything switched or just some stuff? Nipper, I haven't swapped an OBDI motor, just OBDII. Do you know if the JDM Motors are the same OBDI for earlier years and OBDII for later or do they have something different? Well there is the nightmare that one is an OBDII (or the japanese equivilant) and the other is an OBDI. This can be a bunch of re wiring to get it to run correctly. nipper Link to comment Share on other sites More sharing options...
nipper Posted December 29, 2006 Share Posted December 29, 2006 in all honesty i dont know. But i am 90% sure you arent going to find a single OBD I JDM motor due to japanese culture and laws. They have strict emissions so every 3-4 years you pretty much have to get a new car. Japan has the most expensive real estate in the world so they arent many junkyards to find vintage steel. SO that leaves you with a recent JDM OBD II. nipper Link to comment Share on other sites More sharing options...

Nothing major from what I gather, just a few little things like that.Boy I don't know where you got this from, but it has been my experience that the engines (JDM versus US) are the same, for the most part, there may be a few wiring differences, but the plumbing is the same. I have installed a JDM EJ series engine in an Impreza and an EA82 series car and everything, plumbing wise, was in exactly the same place as it was on the US engine. Nipper, most of the engines that I see, with few execptions are OBD I engines from Japan. Having worked in Japan, I also know that there are many cars older the 3 years that are being driven on a daily basis. Yes, they do have tough safety laws with regard to cars, most people seem to live with them and keep their cars longer. I look for JDM WRX engines all the time, most of the ones that I find are between 94 and 96, but they are getting newer model years in lately. As for the ease of installing a JDM into a US model car, the mechanical stuff is pretty much bolt in, with some minor fabrication, the major portion, time wise, is the wiring. Regardless of EA82 or GC series car, the wiring is the most difficult part, an GC (Impreza) is slightly easier because of less mods required, but the wiring is about the same.

Subarutex Posted December 29, 2006 Share Posted December 29, 2006 Kenny... You did a OBDII swap in one loyale. Its going to be the same amount of work to do a turbo motor, and going into the older body style, the wiring will be the same amount of work. Whether its USDM or JDM. I think JDM swaps are great, till you get tired of being stock. Then what do you do for engine management? Yes, there are options for the JDM engines, but they are not widely supported over here. However, if you use a USDM motor, wiring, etc... You can plug and play from the vast aftermarket they have. Engine management? Sure! Utec, AccessPort, Hydra. And, there is the knowledge base and expertise to get these tuned and easier support when the problems come up. My swapped car had a JDM motor, but its being run by a complete standalone computer (haltech e6k). I got the car not running, and it has been just short of a complete PITA to get running and driving. But it goes good now. I had the option of throwing the stock JDM ECU on, and reconstructing the wiring harness... but i knew I had plans for this car. And that I wouldn't be satisfied with it being stock. Thus, i've put int he extra effort and money to make the standalone work. Soon just about all my little drivability quirks will be worked out, and then I can start thinking about power. I don't want to be too hopeful with my overall goals, so i'm waiting till my first "baseline" dyno till I get serious about setting them. Depending on those results... my 280whp ideas may or may not be realistic. Of course... I'd settle for 300whp Also, I'm having a wicked time figuring out whats killing my battery in my EJ22 swapped wagon... any input PM me. Link to comment Share on other sites More sharing options...
Knichol Posted December 29, 2006 Author Share Posted December 29, 2006 Thanks Tex that's pretty helpfull. You are running a JDM EJ22 or are you speaking of two different motors? What year is your EJ22? Link to comment Share on other sites More sharing options...

This is why I said little differences, nothing majorly overpowering that requires hours of intense fab work and the lot. Link to comment Share on other sites More sharing options...

slideshow86 Posted January 6, 2007 Share Posted January 6, 2007 How much total costs for loyale ej swap. Total costs. Already own the car and do all labor your self. Jess Link to comment Share on other sites More sharing options...
suberdave Posted January 7, 2007 Share Posted January 7, 2007 How much total costs for loyale ej swap. Total costs. Already own the car and do all labor your self. Jess it should cost you whatever you pay for the engine ecu and wiring harness plus adapter plate( should be able to find all that you need for $5-600). plus maybe $200.00 for extra parts and stuff... -=Suberdave=- http://www.suberdave.com Link to comment Share on other sites More sharing options...
Dr. RX Posted January 7, 2007 Share Posted January 7, 2007 How much total costs for loyale ej swap. Total costs. Already own the car and do all labor your self. JessThere is no way to tell you what your total cost will be, even ball park figures can be way off. A rule of thumb that I use is, I try to figure how much all the parts will cost, then I double that figure, which still runs a little low most times.

Knichol Posted January 8, 2007 Author Share Posted January 8, 2007 For my 91 loyale swap to 97 2.2 it cost close to $2,200 (myself as labor). Price includes fluids, hoses, radiator, adapter, engine, wiring, ecu, intake, exhaust, and some misc parts. I wanted reliability because I drive it every day so I went with new/rebuilt. You definitely could go less if you shop around, and could definitely go much higher if you wanted! Link to comment Share on other sites More sharing options...
86BRATMAN Posted January 14, 2007 Share Posted January 14, 2007 on a side not the "age limit" on a car in japan is ten years, unles its is of significan cultural value, or you have enuf yen to say it is, or its one of a very limited production, i pray the 22b STi falls into that category or i will killl many many asian people Link to comment Share on other sites More sharing options...

86BRATMAN Posted January 15, 2007 Share Posted January 15, 2007 i gave 300 for the 90 Legacy ls wagon i'm using as my donor car, body is shot to crap and it needs a new mass air sensor, other than that the car ran strong just a few usual oil seapage spots that we are known for, new gasket set from advance is about 150 with my manager friend's discount, new maf about 250, its all relative to what you can find Link to comment Share on other sites More sharing options...
