BruceyWV Posted September 28, 2006 Share Posted September 28, 2006 The more I research this, the more likely it seems like its going to happen. Since my body style was made for an H6, this should be easier than other H6 swaps that have been put into Imprezas.... http://linaracing.com/impreza-h6-conversion-faq.cfm I'm planning on getting the Engine, Radiator, ECU, and depends on how I feel to get an upgraded Torque Converter and fuel pump. This will also be an 02~04 H6, not an 05 since the ECU seems to be a lot pissier and throttle by wire/avcs seems to be more trouble than its worth. I also know that the H6 has slightly stiffer springs and larger brakes than mine, but I think it will be fine. But yeah, in the planning stages now. Anyone have anything negative to say about the H6? I'm mainly doing this for reliability/torque. But everything I've found about the H6 basically calls them 'bulletproof' Link to comment Share on other sites More sharing options...
idosubaru Posted September 28, 2006 Share Posted September 28, 2006 Anyone have anything negative to say about the H6? I'm mainly doing this for reliability/torque. But everything I've found about the H6 basically calls them 'bulletproof' this has been asked often recently with little to no feedback. there will be a very small contingent of H6 owners that pop up on here, they all dig the motor and haven't had any problems. not a very large sampling on this forum of the H6 motor though. not enough to consider a *trend*. so far so good. try a search and you'll see some other posts, i think nipper mentioned one glitch with it in a thread not too long ago.

BruceyWV Posted September 28, 2006 Author Share Posted September 28, 2006 The only thing I've found is there seems to have been a problem with the first year having some rare headgaskets and timing chain problems, but none reported for 02. Thats all I've been able to find. Link to comment Share on other sites More sharing options...
NoahDL88 Posted September 28, 2006 Share Posted September 28, 2006 I would urge caution, as the key may have a RFID chip in it, and if the ECU needs a signal to crank from the key, it won't work without it. Link to comment Share on other sites More sharing options...
fnlyfnd Posted September 28, 2006 Share Posted September 28, 2006 That key thing is good to bring up. I have heard something about them having problems with a timing chain tensioner. other than that its all good. If you want stiffer springs, just get some king/scorpion springs and lift it at the same time Link to comment Share on other sites More sharing options...

BruceyWV Posted September 28, 2006 Author Share Posted September 28, 2006 I'll definately be looking into the key, I think I'll test drive a H6 and set it next to mine and see any differences. Oh, I wonder how more torque at 2000 RPM than my 4 cylinder ever made and 4.111 rear end will be? Link to comment Share on other sites More sharing options...
cookie Posted September 28, 2006 Share Posted September 28, 2006 As a person who has done several swaps I reccomend you buy the entire wrecked car. You can sell the remainder on Ebay to cuty costs. This would ease the job tremendously. I think Josh has a typical tranny swap on his site that will give you an idea of how many times a guy has nto go back to the junkyard for parts. It's amazing how much stuff is just a tiny bit different. Link to comment Share on other sites More sharing options...
xrturbo Posted September 28, 2006 Share Posted September 28, 2006 what about an svx swap? i dont know what you are putting it in but they are cheap, can be found easy, and run forever. Link to comment Share on other sites More sharing options...
BruceyWV Posted September 28, 2006 Author Share Posted September 28, 2006 I'm putting it in the Lesbaru, a 2000 Outback. I also dont know about finding an entire car, but I will try to. Link to comment Share on other sites More sharing options...
idosubaru Posted September 28, 2006 Share Posted September 28, 2006 i'd look into that EG33 swap, excellent point. if that was a plug and play swap that would be awesome. 3.3 liters and non interference (technically it's interference but because of the design they won't actually "interfere). and there are turbo and other add on kits....sorry tangent, i know you want the H6. having the entire car is certainly helpful, but much more so with a transmission swap due to pedal assemblies, linkages, console trim, driveshafts...etc. if the wiring harness is the same, then this will be a fairly simple swap. possible issues: power steering, a/c compressor, intake, exhaust manifold and cross member. i'd guess those will cause minimal issues though. good luck and let us know how it's going. i'm in morgantown much of the week...you close to there?

BruceyWV Posted September 28, 2006 Author Share Posted September 28, 2006 I live there, you're welcome to stop by my house anytime. I'm also not sure about the EG33, the EZ30 was designed to fit into my cars body.. Or maybe my body was designed to figt the EZ30? But I have the same tranny and share several components. The exhaust manifold is something I havent figured out yet. Whether to have one custom made or use the stock one. Oh, Also, I checked into the keys, no H6 owners have reported RFID's on 01~04's. Heres hoping. Link to comment Share on other sites More sharing options...
BruceyWV Posted September 29, 2006 Author Share Posted September 29, 2006 anyone see any issues with keeping the stock torque converter? I know its not fool proof, but cross referencing parts site with EJ25/EZ30, it seems power steering and AC pumps are the same.. I'm also going to replace the headgasket (on the ez30) while the engine is out of the car. Just to be safe. Link to comment Share on other sites More sharing options...
BruceyWV Posted September 30, 2006 Author Share Posted September 30, 2006 I know this is what? A tripple post now. But I was asked to keep everyone updated on my progress with this. So I am. 2,150$ + 200$ shipping will get me: 1 H6 3.0 Engine with 6 month warranty. 1 ECU 1 Alternator attached to the engine 1 Power steering pump attached to the engine 1 A/C Pump attached to the engine 1 Starter attached to the engine 1 Wiring Harness from the engine to the ECU All I'd need after that would be a new radiator. I'll probably go all out and replace the headgaskets while its out of the engine. So thats another couple hundred dollars. Still under the 3,000$ for a used engine put in, and 5000 for a new one put in. Mechanics make good money. Link to comment Share on other sites More sharing options...
Suzam Posted September 30, 2006 Share Posted September 30, 2006 The 2000 front brakes were undersized to start with. The 2001+ were larger. If you can get the parts I consider swapping out for the larger size. Link to comment Share on other sites More sharing options...
cookie Posted September 30, 2006 Share Posted September 30, 2006 did you really say an H6 for $150? sound slike a steal. I would not bother with headgaskets on an H6 as nobody has had a problem with them. Link to comment Share on other sites More sharing options...
idosubaru Posted September 30, 2006 Share Posted September 30, 2006 I'm also not sure about the EG33 the EG33 is essentially an EJ series engine i believe, so it will bolt up to any EJ series transmission no problem. don't know about motor mounts and such though but i'd suspect it drops right in (i mean heck the EJ series motors drop right in the old 1980's EA82 subaru's, complete different body style). but of course there's no way to be sure. i would stick with your current torque converter. i'm sure it'll bolt right up to the EZ flexplate. is your engine coming with the flexplate? i'd bet the flexplate from your 2.5 bolts right up to the EZ motor, but be nice to have the EZ flexplate as well for comparison. i second the notion that replacing the EZ headgaskets would be way over kill. people swap 20 year old EA, ER, EG and EJ engines all the time and with the exception of the EJ25, very rarely do you see anyone replacing the head gaskets even on these decade or more old motors with tons of miles on them. rarely an issue, i wouldn't even consider it.

BruceyWV Posted September 30, 2006 Author Share Posted September 30, 2006 That was 2,150.00 Two thousand one hundred fifty. Yes, I know braking is going to be really ... american, but I'll probably get some upgraded pads and live with short pad life. If its just too little braking power, it still isnt a lot of money to find some better brakes. (Did you guys know my brakes have bigger discs in the back than in the front?) I talked with the stealership, and the mechanic there said a few of the 01's have come in for headgasket problems, along with a select few have a timing chain tensioner problem. For a couple bucks, why not bother with the headgaskets? I guess I might not and put the money into springs and brakes. I'm sure the EG33 is a great engine, but the EZ30 was made for my car, and I'm sticking to my guns and using it. Oh, guys. Have I mentioned Lesbaru spends the majority of its life at 75 MPH? I've averaged 35,000 miles a year with the last two cars I've had, and probably 85% of those have been on the highway. Something I forgot to check about the engine was the exhaust manifold. I didnt ask the yard where I'm buying the parts from if it came with it. Link to comment Share on other sites More sharing options...
idosubaru Posted September 30, 2006 Share Posted September 30, 2006 i can't imagine it being that hard to score an exhaust manifold for this engine. any chance of the 2.5 manifold bolting up or are the heads complete different? a 2001 Legacy Outback exhaust manifold for $75: 1-800-870-2799 a 2002 Legacy Outback exhaust manifold for $25: 1-800-243-6554 doesn't say if it's 2.5 or 3.0 though. Super Repair in Colorado has 2 2003 Legacy Manifolds but I don't think they list whether it's for the 2.5 or H6: 1-888-442-6508 Link to comment Share on other sites More sharing options...
BruceyWV Posted September 30, 2006 Author Share Posted September 30, 2006 I doubt I can use my stock exhaust manifold. I wonder how much exhaust work I'll have to do? Damn, I need to borrow an H6 and set it next to mine. Link to comment Share on other sites More sharing options...
subeman90 Posted October 1, 2006 Share Posted October 1, 2006 to take the heads off you are going to ahve to remove the front panel that has the t-chain in it. I read somewhere that there are a sh#& load of bolts in this housing and it has a special sealent that subaru sells for this reason. It could turn into more of a PIA then you think if you are going to do the HG's. But in all seriousness....+1 for the swap! I am going to be really interested in how this goes....maybe someday my baja will have the motor that it should have come with in it. You going to do the swap yourself? You really don't need anything special tool wise to do this (other then an engine crane) Link to comment Share on other sites More sharing options...
BruceyWV Posted October 1, 2006 Author Share Posted October 1, 2006 Looks like I'm skipping the headgaskets. Any other while-its-out replacements suggested? I am also going to be getting a new set of belts for it, just because they're so cheap. Dont tell me I have to remove the timing chain cover just for it though?

njdrsubaru Posted October 3, 2006 Share Posted October 3, 2006 Valve cover gaskets and Spark Plugs while the engine is out!!!!!!!! will save you lots of twist moments under the engine bay since the H6 sits very close to the frame. Good Luck and keep us posted Neo Link to comment Share on other sites More sharing options...
