So the EG33 is at a compression ratio of 10 right? would it be possible to take it up to 12? how much power do you think that would bump it up to in a completely rebuilt fresh engine?

put cometic .045" head gaskets on, its like 12.4:1
.056 nets you 11.x
cant quite recall of the top of my head

port the damn heads!

It's an 2002 WRX, 32K miles(long story)
EG33 that I got out of a car w 60k on the odo
6speed with RA ratios (3100rpm @65mph! ack)
Tilton twin disc w light flywheel
MS3x/factory ej20 ECM integrated emissions and all (one last piece and its NYS inspection time)
R180, pink sti arms blah blah.
D2 coilovers that finally ride acceptable with the "big block" under the hood.

and although I havent gotten around to the A/c compressor bracket Im keeping my ac. Im bald. Im fat, I sweat man. lol

Ive got about 400 miles on the combo now, Im pretty much happy with the NA torque and fun factor. Lets not overlook the H6 howl either.

Overall the project's difficulty lies in the electronics side of things, otherwise most of it just bolts together. start to finish waiting at the DMV for plates=7 days
My question to you is how did you pass the obd2 check or do you even have it where you are? I know i can pass inspection but i cant think of way to pass the scanner other than keeping the oem ecu in and feeding it some signals from a standalone. Then set the stocker in pass mode and erase all of the dtc codes. Any insight?

Yea, so with just a head gasket change you can get it up to 12?


whats the highest you can go on regular gas?

if you use the stock tune, youshould NOT bump any compression.

you need a tune.

I'd do 12.5 ish w/ 93 and moderate ign

I ran 10:1 with 40* of peak timing allocation on my self tune stock ecu

I do not have the engine yet, I am just thinking and planning ahead as whats the best course of action when it comes up

I need to do a bit to my car before bumping up the power that much, I have a WRX transmission and drivetrain to, I need to convert the rear brakes to disc and get a new suspension in the meantime

but I am thinking that 250 WHP would be the way to go NA style, a porting and a bump of compression with a tune should do that you think? or would that only net 250 at the crank?

250whp is going to need:

long tube headers
a REAL intake, similar to the FAPFAB ones I used to make
ethanol
injectors
aggressive porting
aggressive tune

I ran a 13.2@109 with a stock longblock eg with my intake/tune in a fat 00 rs.
so 200ishwhp. I also had a 1.7 60 so I was beating it hard, that really helps et.

well I was looking into toying with some ITBs, picking up the ones for a 1UZFE and modifying it to fit a EG33, or having some custom made, ITBs are important to me.

I do NOT want to run alternative fuel, this is looking for a DD type of setup, and NA is the way to go

then down the line switching the setup for lower compression and a supercharger, removing the power steering pump and using the electric pump from an MR2 and fabbing a manifold to go over the supercharger.

I machined the unused 2nd trigger off the back of the EG33 crank sprocket, and machined the 36-2-2-2 wheel off the Ej205 to press fit on the Eg33's gear. Hooked it up to the factory ecm, tuned off the unused electronics with ECuflash (like the cam sensor) and hit force pass. Viola. OBd2 sticker, factory idle control, factory Ac control etc.
Now Im working on an all electronics based solution with the guy's from megasquirt/jbperf. Simply passes RPm down the can bus to a small processor that outputs any of the "jimstim" wave forms. Subaru triggers,both 36-2-2-2 and the 6/7 are in there. Engine swaps among obd2 cars will now be significantly easier.

2003 GD w/EZ30D swap

Default

few basic questions:

what's this madness with lower engine mounts? if i'm swapping, what am i doing with crossmembers/mounts?

ez30's: i like the simplicity of no avcs and a cable throttle, but single port headers are very undesirable right?

oil pans & pumps: the pans are interchangeable between the ej's and ez's, but what about the pickups, baffles & pumps?

Gets the motor down so alternators clear the hood, iirc.

meh....the port is huge. Torque is good, and I'm reading that over 3000 rpm, these motors really shine. There is nothing simple about the wiring to get an EZ30 running (with a manual trans) without a CEL.

Maybe the EJ and EG, but the EZ is a different animal altogether.

I don't know what the madness is with lower engine mounts. Stock mounts will drop right into your stock crossmember.

Well, they're certainly not optimal, but whether they're "very undesirable" is hard to say. Depends on what you want to get out of the engine. In stock form, the EZ30D is still a heckuva lot more powerful than an EJ25, even with the single exhaust port on the heads. This is a comparison of the advertised power/torque curves for the EZ30D and EJ25D. So, if you just want an engine with more power and torque than a N/A EJ25, then the EZ30D will suffice. If you're trying to really optimize the power from the 3.0L, then the single port heads are definitely a stumbling block. How much of a stumbling block is awfully hard to say, since there's almost nobody doing any modding of either the EZ30D or the EZ30R.

Not sure where you got the notion that the oil pans are interchangeable. They're not even remotely close to being compatible. The oil pumps are different, too. Not sure about the pickup, as I haven't removed the oil pan from my EZ30R, but I would imagine it's different as well.

Edit: Here's a shot of the oil pump:


And this shot wasn't intended to be a picture of the oil pan, but it's the best I've got. You can see that the oil pan is a two piece deal, with the bulk of it being a cast aluminum structure that is really part of the block. I think a lot of engines are built this way now-a-days - the oil pan isn't just a stamped steel thing bolted to the bottom of the block, it's actually a structural component to help strengthen the engine.

intredasting.

my intention was to build it up fairly mean for forced induction and the racetrack. wonder how killer b feels about H6 oiling...

thanks patrick. now to do some head/cam/etc research.

Oiling only is an issue on EZ30R engines, the first gen EZ30D has no oiling issues. The reason for EZ30R being critical is the huge oil flow draw of the valve lift solenoids.

If you haven't already found them, definitely look for threads in this forum by anders8, who put an EZ30D in his rally car.

I just seen the response. Do you have a build thread because i think you may be some sort of mad genius.

Lol, thanks but Im just a determined hillbilly with some interesting tools. I dont have a build thread up yet, Its being featured in Median Magazine next issue so I have to make sure I dont step on my editors' toes when it comes to content.

Next Eg33 swap in my shop: 99 forester/5sp.

I'll say this to those considering the swap- it's only as hard as you make it and no other scooby engine matches the EG for snappy-right F'kn NOW throttle response and torque. Esp with a very light flywheel.

Have you had a look at the oil galleries especially to and from the filter, plenty of scope to improve oil flow.

I'm not sure I'm completely following... Which crank sprocket and cam gears are you using? Are you using WRX cam gears and crank sprocket?
