V7 EJ207 into 02 Bugeye Swap
Hi Everyone,
I don't want to clutter up the EJ207 Owners thread with my questions, so I started this one to consolidate all the questions I'll be having while doing my swap. My hope is for this thread to help those deciding to go with a JDM V7 and hopefully serve as a resource for those who are/were in the same boat as me. I've swap many B-series, but this is my first attempt at a EJ motor and so I am as clueless as it comes. And the best way to learn is to get your hands dirty. As I go through the steps, hopefully those with past experiences can chime in with tips to help others. The run down: I decided on the JDM swap since one of my cylinders showed only 30psi upon compression. Rebuliding the EJ205 would've cost ALMOST as much as complete swap, so after reading the EJ207 owners thread (all 187 pages at the time), I made the decision to go ahead with the JDM engine. My main goal was to have a reliable DD with a bit of extra punch (and extra insurance with the forged internals), that I can take it to a HPDE event maybe twice a year. I'm not going crazy with power upgrades, perhaps Stage 2, or sometime down the line a slightly bigger turbo than the stock VF30. I wish I had the money to buy the 6spd, but I will have to hold off on that until the 5spd finally dies. Here is what I have purchased and the cost: Required: Ver 7 EJ207 (EJ207DW3R) long block: $4000 shipped Gates Timing belt kit with water pump: $290 shipped NGK BKR7EIX spark plugs: $29.00 shipped AVCS wiring kit(used): $50 shipped via NASIOC classified (IAPerformance sells for $200) Mobile 1 Synthetic ATF for powersteering pump: ~$10 for 1 quart Peak Long Life coolant ~$12 for a gallon Optional: Koyo Radiator: $315 shipped Samco Radiator hoses: $110 shipped Exedy OEM clutch (KSB03 from Amazon): $173 shipped I will try to update as I go along with the swap. I received my motor yesterday and proceeded to clean and change out all of the maintenance items. NASIOC Threads that helped me along the way. Thanks to the original posters of all these threads.

In order for the computer to recognize and read your vehicle, you MUST utilize a USDM ECU and have the TGV codes forced to readiness.

Here is what the motor looks like when it arrived.
The difference in size between the two TMICs The year code, stamped under the oil cap The belt looks very decent for a 12 year old motor Upon further inspection, good thing I bought the Gates Timing Belt kit: Upon further, further inspection, I found the crack. I have heard of the cracks on VF39's, but not on a VF30. Things I've completed: Timing belt and pulleys changed out Water pump changed out Spark plug changed out General cleaning; there was virtually no oil leak to speak of. Things I have to change out still: Power steering lines Switch the AC lines Vacuum lines Wire in AVCS |

Sounds like you've got things under control. I put an EJ207 into my 02 2.5RS which was a little more involved. Are you sticking with the OEM 5 speed or getting the STI 6 speed?

Reading fail for me. Sorry about that.
Probably the transmission code off of your transmission housing... but I haven't heard that rumour. |

With work and two young children, finding time to work on the car is sparse and far in between. Bare with me as I snail crawl through the swap.
I got to pull the old plugs off the EJ207. Is PFR7G a stock Sti plug? I opted to use the BKR7EIX Without flash I suppose I am glad it's black, which meant the motor ran rich, rather than white speckled, which would've indicated the motor ran lean and encountered knocking. Plans for this weekend: Pull old EJ205 out repin and wire AVCS send flywheel for resurfacing degrease engine bay -Jeff |

2002 WRX transmission codes
Take a look at the plate under the hood on the drivers side. It has the codes for the vehicles equipment. Under transmission you are looking for the ending letters AB. These gears are wider. My dealer did not know what was up. The standard width gears have the code ending in AA. I am the original owner of my 2002 wagon.

engine code ending with AA= Standard gears, narrow gears engine code ending with AB= RA width gears, wider gears I thought the RA gears were shorter (narrower) than standard gearing?? -Jeff |

Gears
I think you have it reversed, the wider are RA. What I do not know is whether the gears in my tranny received the RA treatments? Or are they just the same size as RA's?
It has held up well with 166K. This may be a better question for AndyRoo at Andrewtech. |

the AB trans is not an RA transmission, it's just RA-width. Same ratios and whatever, just slightly less prone to breaking. The switch was somewhere in the bugeyes, I believe a bit through USDM MY 03.

Got the EJ205 out!!!
With a buddy's help, I finally got the old motor out. If it wasn't because I had to pull the axles out to loosen the bottom two nuts on the bell housing, it would've taken only half an hour. But alas:
Here what a stock 160K clutch looks like. This is just normal driving, without hard launches, or high RPM shifts. Close-up look: While looking over the vacuum lines, I noticed that the JDM EJ207 does not have this valve, I believe the EVAP checkvalve, as the inlet on the intake has been sealed with a bolt. Lastly, I broke this vacuum line that goes from the turbo to the BCS, right where the "connector" is. Can I simply replace it with a longer vacuum or do I have to purchase the line with the connector from the dealership? To be continued. -Jeff |

^^ is that the restrictor pill... 'cause that has to be intact in order to maintain correct boost pressure.
Nice thread btw... subscribing to it, as I may go this route on my bugeye in the future. Did the motor come with a good engine wiring harness? |

FWIW I matched everything as 04 STi since the parts design superceded anything designed during the 02-03 years. |

This is the one I ordered: Gates Timing Belt Kits & Components for 02-11 WRX/STi Item# Gates-Timing-belt-Kits-Components-WRX-STi that includes the water pump: $309 shipped from importimageracing.com. The idler was different from the stock idler; the "face was protruding out more", if that makes sense. You will need a slightly longer bolt, otherwise, there isn't enough grab on the block if you use the same bolt. I went down to the hardware store and got a M10x1.25 bolt. For those who are still confused whether the V7's have TGV's or not, here you go: EJ205 TGV, see connector? Here is the EJ207 that has the deletes, noticed the runner doesn't have the recess for the TGV solenoid (the blank behind the oil dipstick). As you can see, there is a TGV riser, unlike the V8 that has a single long runners. Got a newly resurfaced flywheel -Jeff |

nvm just read fastnoypi post didnt see that, so my safest bet is to get the 04-11 kit. and is it not true, that the ej207 uses a harder belt materieal then the usdm sti's because of the higher read line?

beside re-pinning the avcs wiring is there anything else with the wiring to make this swap work with a 02-03 wrx?

iWire
They can make you the harness for your conversion. Wiring hassles seem to be a major reason why these swaps never seem to right. iWire will save you many many hours.

if you have the 02-03 5sp, there is nothing else wiring wise you would need other than making sure the avcs wiring is correct, the NPS is the right signal. You can add the wires needed and follow the DS1 wiring diagram or buy the IAP avcs kit, instructions are straight forward.

If the EJ207 you received has the engine harness intact (like mine), you just need to add a AVCS bulkhead harness, which you can either purchase from iaperformance.com AVCS Bulkhead wiring kit, or have someone on this board make one for you, PM me if you're interested.
I got lucky and bought the wiring from someone in the classified. And here is the DS1 AVCS wiring instruction. I'll take pictures when I wire mine up this weekend. -Jeff |

AVCS wiring help
Alright, I knew I would have a hard time with this. I am trying to follow the DS1 Motorsports wiring instructions and I am confused. Before I get to the my question, here is how to get to the ECU.
The ECU is located under the carpet on the passenger foot well, you will need to peel back the carpet and loosen 4-6 10mm nuts. This is what you'll see when you peel the carpet back Here is the ECU, bolted down to the floorpan by two 10mm nuts: So on to my wiring question: On page 3, here are the instructions: So which connector is B84, by the count of the ECU pins, it looks like the middle of the five is correct, isn't it? If it's the middle one, then it doesn't match up to the picture in the instructions. Secondly, the first instruction under "JDM" specifies to move Pin 4 to Pin 6, on the connector that I think is B84, there is no wire in the Pin 4 location. Am I looking at the wrong thing?? Thanks -Jeff |
