    Ok not trying to make any restatements or anything but you all caught the part in the FAQ where he said that the EZ30 bolts right up to stock EJ transmissions right? Means no need to change drivetrain (until you brake it) and leaves plenty of room for turbo in theory.

    Once upon a time I thought I needed an automatic. I now wish I could go back in time and smack the shit out of myself.

    Yes, thats what the statement means....he is saying that nothing needs to be modified for proper mating up between an EZ motor and an EJ-style tranny.

    ....and I think you mean 'break' it.....or was that engine brake?

    You can go ahead and figure out whether you can safely strap on a turbo onto an EZ30....there is one such pioneer on NASIOC (and I think 1 before him) who is tackling the project of a late model EZ30, turbo'ing it and mating that to a STi 6MT.

    BUT, he is re-working the internals. Have fun.

    And if you plan on turbo'ing an EZ30; then plan on either not using it to its fullest potential, then go ahead and pick any ol' EJ tranny.....or you going to have to get a 6MT if you want to have fun. People talk about making the RS or WRX gearbox stronger by adding RA gears, which are stronger GEARS....but I think that's just a bandaid cause the CASE is still the weakness in that equation = flex under load.

    6MT = IF any flex, FARRR less than a 5MT factory box.

    umm yeah I was tired when I wrote that anyways and that's a word I'm bad for switching spelling of lol... I did mean "break" it. And all of that stuff is EXACTLY what I'd do. Right after I win the lottery. *runs to convenience store real quick*

    Chances of any of us doing above said mods are pretty slim so it's just fun thought.

    RS-RA gearsets are marginally better than stock. They are not the be-all end-all uber-ultimate gears. You can still break them, if you halfway tried.

    Hi, I'm slim, have we met?

    I'm working on a JDM Ver8 and 6MT swap....actually collecting pieces....yes to go into a 2nd gen Legacy.

    You guys will know when its done.....

    Tris, the only reason I stated it like that, is due to the huge number of people going for RA gears vs. the 6MT....but part of that is the sheer capital needed for the 6MT.....but if you're serious about the power, you can spend the extra coin for the 6MT and not risk a whole lot.

    Mark -- this is not the place to pry you whore! Back to topic: Wouldn't modifying the ej tranny to fit an EZ mess something up as well? I would guess you'd have to drill new mating holes...and drilling holes in places that aren't reinforced for the stress that's going to be exerted against the bolts that are attached through them can possibly = cracked case? I just don't like the sound of it.

    Ryan, I don't think there needs to be any mods to the tranny to mate up to the EZ. Thats what the 1st couple posts on this page is trying to get straight.

    PhatSuby on NASIOC is mating a 6MT to a EZ30....he hadn't mentioned that he needed to modify the surfaces or bolt holes to complete that portion of the project.

    I think where it becomes an issue is where people try to mate a current style tranny to an EG33 (aka SVX).

    I thought AFBeefcake said that there was no problem when he did it (he owns an SVX).... :shrug:

    eg33 = ej22 with 2 extra cyls and dohc. Pretty much anything for an ej22 works for the eg33, including the wrx trans, and iirc the timing belt.

    Yeah, exactly. 2.2....3.3, same engine, block is a little longer with 2 extra cylinders.

    If the H6 engine fits into LinaRacing's Impreza, then there's no reason it won't fit into the Legacy.

    Probably a little more room to manuever too.

    Also, the reason the STi was created in the US with a 2.5L is because Subaru didn't want to compromise the performance of the car because of the stricter EPA regulations. Generating sufficient power was only possible by using a larger displacement coupled with a mid-sized turbo.

    There are a tonne of STi's in Japan, NZ, Australia and the UK that put out the same power as a stock USDM STi. the "206kw" ceiling was a "gentlemans" agreement between major Japanese car manufacturers.

    Also, WRC rules prohibit the use of engines bigger than 2.0L.

    Anyway. An H6 conversion isn't impossible. The biggest headache would be the wiring loom.

    Personally, i would stay away from the EZ30, i don't like the fact it uses a timing chain. It will fit better in a legacy than the EG33 but the cylinders are closer together, meaning thinner cylinder walls, meaning not as strong as a block. I have seen a EG33 in a legacy but i am pretty sure they had to do something with the radiator. The EG33 would be better for boost because you can put ej22t low compression forged pistons(same bore and stroke).

    Tristan ended up getting a WRX swap anyways

    but I agree, the EG33 Engine is basically an EJ22 with two more cylinders, its a very good engine, leaks a lot less oil than the EZ30, and there's no replacement for displacement. The EG33 is a torque monster.

    However, it doesn't have AVCS, like the EZ30.
