OMGHi2U So... Who will be the first to swap the 3.6?



Same dimensions as the EZ30...
TONS more torque...
A bit more HP...
Better MPG...

Who will be the first?

I have like 50 posts in that thread...

But we still need a 3.6l source/containment thread since it is a new, seperate motor from the EZ30. But since its still using the same basic design, which I actually thought was going to be a timing belt instead of chain from what I heard, means it will fit just the same as the EZ30 in various other engine bays.

The wiring/etc will probably even MORE complicated than the EZ30, but considering this motor is significantly more powerful, this might be more worth all the extra crap you have to go through to use the motor.

I just had another thought...

This engine might end up being a simple swap for someone with a 3.0R outback wagon/sedan or even the current tribecas, depending of course on how different the sensors/wiring/etc. are laid out. If its close though, might be interesting to find a used 3.0R 05 outback sedan and swap in this engine and a 6-speed...

i am messin' with ya

i don't think it will be a big swap canidate
its stil WAY WAY WAY more work than a ej205 and less power (assuming stage 2)

until a uber flexable can bus standalone ecu comes out .. i dont see it happening at all

what are the bore and stroke of the ez30

Hmmm... small overbore, but they stroked the piss out of it.

I wonder if there's anything in the heads that I could scavenge for my car - like valves or cams.

some interesting info for those who haven't heard:

2008 Subaru Tribeca - Auto Shows

Subaru’s slow-selling mid-sizer gets a new 3.6-liter engine and less polarizing styling.
April 2007

Although the availability of a “real” SUV in the form of the B9 Tribeca bumped overall Subaru sales past the 200,000-unit mark in 2006, sales of the controversially styled mid-size SUV were considered mediocre. In response, Subaru is bringing out a hastily revised version. The new Tribeca (the B9 suffix will be dropped for the 2008 model) features fairly comprehensive front and rear styling revisions, replacing the controversial Alfa Romeo–like cues with more conventional treatments. At the same time, the flat-six powerplant is being boosted in capacity from 3.0 liters to 3.6 liters in the interests of better performance and economy.

But here’s where it gets interesting. The flat-six engine (or H6, as Subaru calls it) is already a tight fit in the Tribeca’s engine bay. Since the H6 is a horizontally opposed layout, any significant increase in crankshaft stroke would result in engine-block deck-height increases that would make the engine too wide to fit in the existing structure.

The problem was exacerbated by typically thrifty computer-aided engine design, which left minimal space between the engine’s cylinder bores. Subaru calculated that it could safely increase the bore size from 89.2mm to 92.0mm, but that change would have bumped the displacement to only 3191cc. Subaru needed more than that for the performance improvements it was seeking, so it came up with a novel way of increasing piston stroke without raising the cylinder deck height. The answer was an asymmetrical connecting-rod design (which looks somewhat like a lamb chop) that permits the piston to travel farther downward into the crankcase and increases the effective stroke from 80mm to 91mm.

Who cares who will be the 1st to swap it.

The real question is: Who will be the 1st one to turbo it(maybe twin turbo?) and then swap it? Maybe into a GC8 2dr?

i'll do it!

i just sold my V4 swap to a friend who wants to build it.

so im searchin right now for the project car/chassis right now!

who's gonna donate the engine? i can afford the regular EZ, but a new 3.6 R may cost a bit more than i'd like. i can do either H6 save the new one maybe(cost).



--keith

and i have a couple turbos and IC's laying around

I think this could conceivably be twin turbo-ed and get decent performance out of it. But I'm willing to be a single larger turbo would give you the same spool, and gains, with less complexity.

THe Best rule on any project like this thats never been done before...Keep It Simple Stupid!

Where would ytou source that motor? Is it in the JDM yet?

one more not to this is the incredibly thin cylinder walls wouldn't do too well with boost either
there also really isn't much room for sleeving of any kind on the EZ30 much less the "EZ32" bore...

yes I know I quoted myself but quoted so people won't over look these issues that would arise in building a boosted EZ36 application

Ahhh let em' do it. I love watching people do stuff like this and
then wonder why there engine Gernaded on em'.

The motor isn't closed deck is it? Even if you didn't kill the engine internally It looks like this thing would be prone to Head gasget faliure. If I had the block I would do everything I could to keep it N/A and run with that... Every one wants boos but geez I think N/A is more fun!!!

I have no interest in seeing one turboed. The current EZ30R doesnt like being turboed, and this one is even more sensitive with a longer stroke and thinner cylinder walls. Its not a good engine for turboing.
