| So I am in California and I was given an old Kennedy conversion kit so I am now looking into a C.A.R.B. compliant Subie 2.2 swap. I keep reading that I need a 1990-94 2.2 donor car but the E.O. states that a 1995 works as well. Am I missing something? Will a 1995 work as well? |

Thanks, that’s exactly the info I was looking for. I found a clean 03 Legacy 5 speed wagon with a rebuilt motor for cheap. Was thinking of picking it up, but the vehicle has higher miles: about 300,000km (186,000 miles).
If in fact the motor has had a full rebuild milage shouldn’t matter much, but one persons rebuild is another’s reseal and head gasket. |

Todd mentioned in an earlier post that the 2000-2004 SOHC 2.5 is the best bang for the buck. This is exactly the info I am looking for. I'm looking for a winter beater to replace my old winter beater. My intention is to buy a car that I can get to know well and sort the engine on, then do use it as a donor for my T3. Which Subaru cars should I be looking at with the intention of eventually using the engine for the Vanagon swap?
If it matters, I have a 1987 Westfalia with an automatic transmission. |
I like the early 2000-2002 EJ25 SOHC legacy/outback/forester/Impreza for donors. They can be found without EGR and have a few less wires and redundant CEL's then the late 03-04 models.
BUSARU has great videos on how to convert the harness.
Since you are in BC and rust won't be an issue try to find the lowest km or best maintained one you can for cheap. It can be a manual or an automatic Subaru donor … into a manual or automatic vanagon doesn't really make a difference. |

stupid question here - on this subject.
I have an '86 syncro that a previous owner installed a subaru legacy 2.2 motor with a kennedy conversion.
All is good and fine. But I always like to think of the future. If I ever had an extreme issue with this motor - will I need to get another 2.2 subaru to replace it? Or can I get any subaru motor - or rather what year/type motors can I use without having to replace the whole conversion kit? |
you can run a SOHC 2.5 with the same 2.2 management, but there are a few things to consider such as PCV changes...some had the valve in the block, others had it on the intake. you also need to watch the tooth count on the cam and crank triggers.
I also use the 2.5 DOHC injectors with my build. see below
as long as it's not a AVCS engine it should work just fine. I built a frankenmotor for my bus. it's a bit of a mash up of parts but I really won't suggest it just due to the fact there are custom head gaskets etc...kind of blows the simplicity factor out of the water. fun engine, makes gobs of power but a healthy 2.5 and a set of cams is almost as good.
the reality is these engines are pretty stout. you could stockpile 1 or 2 spare engines for future rebuilds and probably never need them. in terms of the JDM stuff...do some reading. many have had really bad luck _________________

Hey friends!
So I'm working on trying to get my hands on a Subaru engine so that I can convert my '85 for my move from Oregon to Colorado in mid October. I want to put in something reliable because this will also be my daily driver once I get out there. I've tried in vain to track down the elusive 2.2. I have a guy out here that's willing to help me get a nice, shiny 2.0 from Japan, but I've popped around on the forums for anything about 2.0 conversions, and I'm not really coming up with anything.
Thoughts for a conversion project newbie? |
You know that's a month away? That's a short time table. The JDM engines I've seen are junk. Haven't seen a Subaru engine, but an engine program that wasn't sold in the US is a flawed program if you can't get parts for them at a later date. |

My 2.2 was getting a bit long in the tooth in my Westy, and I had RMW take it out and re-seal it (cam seals, belt, gaskets, etc.) That was four years ago and it's still humming along nicely for the new owner. _________________ Joe T.

Just finished my second conversion a few days ago , first was my 85 weekender now in my 90 syncro...my 2 cents.
Find a 2000-2004 SOHC 2.5, moderate miles are fine. Pull the heads have them redone, put in new pistons and rings, head gaskets, water pump etc...None of that is at all that hard to do, no special tools needed, just basic skills and patience.
Get a harness made from Jeff at AutoVentures, they are the absolute best out there, truly plug and play. Period.
IMO the RMW kit is still the way to go for simplicity and quality, also Alex at RMW who handles orders is a great guy to help you order and sort out any issues along the way.
There are many,many years and types of Suby engines that can be used but the SOHC and the years I listed are tough as hell, easy to work on and find parts for, and the wiring harness is one of the easier to make up or have made, not to mention all of the info here on troubleshooting those years.
Good Luck, Todd |

There are literally dozens of engines that can work. The pool dries a bit after 2003 or around there, but the EJ25x series all work. Colorado doesn't have an issue with what engine you put in, that is California.
Plenty of info on vanaru.com or busaru.com too.
Good luck.
I got he Kennedy kit, it fits well.

I've considered going with the 2.5. But I'm really worried about having to deal with blown headers. Which was a big reason why I wanted to try to get an Ej22. I know there's been talk about installing newer headers to prevent that issue, even so, I'm still hearing mixed reviews on how effective that really is. |

parts are NOT interchangeable from JDM and USDM units. everything is just different enough to be a total ass ache and the electronics are Japan/Asian market only. I have watched too many suffer thru this only to be let down. I strongly suggest you find a car built for the US market.
people have had little to no luck with the wiring diagrams for the JDM stuff and have let the magic smoke out of the ECU more than once. |

I am in the process of doing a EJ20 from Japan (JDM) it seems like the same other than the wiring harness which I have been able to find diagrams online.
