H6-EZ30 engine in the 818----IT FITS

[Wayne Presley]

Disclaimer-FFR is not supporting the H6 in technical, parts or any other aspect. They are only supporting the 2.0 and 2.5L four cylinder engines.


I ran the donor yesterday morning with the cat back off of it and it sounds so sweet. Sounds just the 911 Porsche. Pulled the donor apart yesterday, pulled the motor out of my 818 this morning, had the H6 in by 10AM, removed it and had my motor back in before lunch. The motor bolted in to the stock location, had about .300" clearance between the passenger side timing cover and frame. Exhaust will have to be custom and the upper coolant has two ports instead of one and will require a 2 into 1 manifold/T of sorts. Did I mention I love the sound???

Lets hear it!

[David Hodgkins]

Hoo hoo hoo, I'm ready to see that run too! What's the HP rating, and what models does in come out of?

That's awesome!!!! Can't wait to hear it (you are going to let us hear it right? )!

[SkiRideDrive]

This is awesome.

and just to fuel the fire....

Nice. I think the only "issue" with the EZ30 was engine management if you didn't want to spend big bucks.

Pretty cool how quickly you had it in and out and back again. lol.

[Silvertop]

"The Sound" is the primary (maybe the only) reason I would ever have seriously considered trying to shoehorn an H6 into this car. To me, the Porsche flat 6 has always been one of the prettiest sounding engines around -- and I had no doubt that the Subie H6 would sound very similar. I'm pretty sure my custom EL headers for my NA H4 will make my 818 sound good -- but there's really no way to make a four-banger sound like a six. I do hope you (Wayne) recorded the sound before you took the engine back out again. Because you're probably going to be HOUNDED until you produce an audio of it. Which means putting it back in again.

Well, come to think of it, another really good reason to put in the six would be for the broad torque curve. I'd love to have that.

Yup, that's the sound -- though unless I'm way off base, that IS a flat six Porsche, not a Subie trying to sound like one. Looks like you had some fun there. Classic battle of brute horsepower vs. phenomenal handling. I can't believe how quickly you caught him up in the turns -- but how easily he was able to pull away in the straights. Had to be fun, though! You drive well!

Does the transmission bolt to the frame in the same location? Even though FFR doesn't support the H6, one could start with a NA build and upgrade to a H6 later.

[skullandbones]

Wayne,

So that means the CVs, shafts, etc all line up and the diff fits within the body panels? I suppose Electromotive could support it with a stand alone system. They've done everything else, I think. Love the exhaust note! Thanks, WEK.

Great race! Sounds good too.

Wayne-

I need to hijack a line from the Adam Sandler movie Mr. Deeds. "I think you underestimate my sneakiness Sir!" You Sir, are quite sneaky!!

Congratulations again on your very coolness! I am slack-jawed! Keep on rocking.

The trans is in the same location.

All fits, the only tight point is one of the cooling inlets but not a deal breaker

Me sneaky? Nah, just wanted to see if it could be done. The flat 4 sounds great between 3000 and 7000 rpm, just not so much at near idle speeds. Now the flat 6 is pure music to my ears, and that sound tucked in my FFR 818 will be heaven! Dropping the motor in the chassis requires some creative manipulations if you have the intake on the engine. It has to go in about 10° nose down the the tail of the trans swung over to the drivers side about a foot.

[Xusia]

Just seeing this is making me consider blowing my budget and dropping coin on an H6 and engine management. LOVE the sound. Not the smartest reason to spend more money, but man - SO tempting!

[Flamshackle]

ok this is a game changer!!! great work Wayne!

I think a turbo 6 could make this little car a real hyper unit!

[Silvertop]

I'd be just a little bit nervous about that .300" clearance between the timing covers and the frame though. Engines DO move a little on their mounts usually. Might have to make some minor frame alterations. But yes, it's tempting, isn't it?

Personally, I think adding a turbo would be overkill. The thing would probably be bordering on stupid fast in NA mode. But that's just my getting-to-be-an-old-guy opinion. Whatever floats your boat!

[tirod]

Now some of the pressure is off buying up all the WRX wrecks. I see your sneaky game plan, diverting attention to the H6.

It's completely natural of course - if some's good, more's better. Enough people beating Dave up on the H6 will likely get some attention to making it an option, the MkII would get a "firewall" upgrade to fit better, etc.

So, finish that car and give Dave the keys. You know he will be hooked. >;E

[RM1SepEx]

set the drivetrain back an inch, the CV's should handle the small longitudinal offset... slight mod to the rear bodywork...

[SkiRideDrive]

Forgive my ignorance, but could any of the cars which include the more recent H6 (Found in the 2003–2009 Legacy 3.0R, Outback 3.0R and 2006–2007 Tribeca. according to Wiki) be a nearly complete donor? I believe many of these donors would have an auto so you may need to source a transmission and work around the wiring issues, but any comments on whether everything else should work?

Thanks!

[skullandbones]

I think someone will cram an EG33 (3.3 liter) into one of these. They are relatively cheap (not on the Subie enthusiasts radar yet) and can give enough HP with just NA. No replacement for displacement is still valid for small engines, too. Proving that you can put a H6 in without modification is going to open Pandora's box so to speak. Can't wait to see the first build with a six banger! WEK.

None of those are complete donors, the vast majority of the H6's are automatics. The 2005 Legacy GT I pulled apart I was unable to use the lower control arms, rear knuckles, rear trailing arm, lateral links, and dash. The 2004 Outback that the H6 came out of had the same parts not usable plus the automatic trans.

[SkiRideDrive]

Thanks for the info Wayne.

[Turboguy]

Thank you VERY much for doing a test fit and letting us in on the results, Wayne!


Do you think the 1/4" or so clearance is going to be enough? I'm sure the frame and/or firewall could be modified to increase clearance in that area if need be.

I hope the H-6 uses a timing chain, as you'd almost certainly have to pull the motor to do a timing belt.

Yes it does use a chain.

[Movieman]

Stay tuned for next week when Wayne shows everyone how to install the engine from the Lemans winning Gulf Porsche 917-30 into an 818 by simply bending two small parts!
Wayne: Did I tell you that you impress the hell out of me!

From previous discussions, it appears the EG33 is at least 2-3" longer than the EZ30R Wayne installed - with the EZ30 having only 0.300" clearance, the EG33 will likely require major work to make it fit. The EZ30R also comes from the factory with about 30HP more on tap to start.

Yeah, I remember now. That will take a skilled fabricator to pull that one off! Thanks, WEK.

Yeppers, the EZ30r came with about 250hp and the EZ30 came with about 212hp. The heads on the EZ30 aren't conductive to FI, so if you wanna turbo you need to go for the EZ30r or convert an EZ30.

I understand the feeling, did the same to my SVX donor before swapping it into my legacy!

oh my god. This is amazing.

I checked ebay quickly and it seems there are a few JDM EZ30's for sale. Is anyone aware of any reason why that couldn't be an option?

[PhyrraM]

The earlier, non "r", EZ30s came in car that could be a partial donor for the front suspension pieces. The 2000-2004 Legacy/Outback uses the same crossmember based front parts as the Impreza. The rear suspension is different and would need to be sourced from another appropriate car.

No H6 came to the North American market with a manual transmission from the factory.

Engine management??

[Turboguy]

Engine management??

For those already building with an aftermarket body harness, why not go for standalone engine management?


Wayne of Very Cool Parts (a forum sponsor and LONG time FFR builder) sells the TEC systems plus there are outside solutions like Motec or Link to name a few. It's no biggie.

[nikbrewer]

would this be a good deal / fit?

How much ground clearance under the stock oil pan?
