EZ30 question

[Wangan Wagon]

Hey guys. I have come across an EZ30 (not an EZ30R) for $950CAD so I'm looking into it. I was wondering if the JDM EZ can run off of a UDSM ECU without changing all of the sensors and wiring? The motor doesn't come with a wiring harness or ECU. So if it can't I will be running Hydra, although I won't really tune the motor serious enough to need a standalone. Also, I still want to run hotrod emissions and have OBDII capabilities. Any help would be appreciated.

I would advise against Hydra if your not going for a full tune. There is no "universal" tune that you can plug and play. Hydra has to be configured and calibrated even for a base tune. Your going to spend some big bucks at a tuner shop just getting hydra up and running.

In many cases its possible to use a EZ long block with USDM intake manifolds. This would allow you to keep USDM sensors (cheaper and easier to find) Also IIRC EZ blocks use drive-by-wire DBW.. DBW is not easy to play with so keep that in mind.

But to be honest.... for $950 Canadian you can source out an entire SVX EG33 but its going to be AUTO. There are many threads on NASIOC about converting the EG33 to run a 5MT or 6MT.

I know this isn't the info you need but it should give you some sort of insight.

lol Been there, thought that... I looked into this about 6 months ago. What was said above it pretty much right on. The only thing I would say differently is that the First model EZ's were not drive by wire(03-05 I think.......???) Once the EZ30R came out, it went to the drive by wire system. Also, what Subaru do you have? I would imagine that you have a BE/BH.

Oh.....so it is MUCH more difficult than I thought.
Actually, I'm the same nut as you. I'm running a 96 BK Legacy L.
My only issue with the EG33 is that there doesn't seem to be any room to play with from the firewall to the radiator support is almost none. So Chuck, what you're saying though is that if I convert the JDM intake manifold to a USDM one, then get all of the USDM sensors, I should be good? But hell, that's alot of money in it's own right.
So in your honest blunt (please be blunt, it's more definite) opinions, should I try this or not? I'm really not trying to be any sort of pioneer. I just want to make about 300BHP without killing the bank. Then again, a standalone setup detroys the bank alone....

[LunchBox04V]

Well, lol at least I am not alone in crazy town. I would say 300hp would be a reaching.... Stock the EZ30D is single exhaust port(not terrible, but not the best). I was tryingto do the math and essentially if I did a computer and exhaust, 20-25% gains would be AMAZING. Stock it is sittig at about 215, so 20% would be 258hp, which is stock JDM EZ30R territory. I am not going to say don't, but it would be hard to get to 300hp N/A. It would be a nice daily driver though.... The torque curve is almost flat.... Really, it is pretty cool. If you were going to boost.... I saw a picture around here somewhere that explained it pretty good.... In order of the picture it was EJ20 STi rods, EJ22 rods, then EZ30 rods.... The captian was "Bomb proof, bullet proof, airsoft proof." lol I could forward you the info I found if you wanted. I could search it when I get home (working now.... Wait to board.... God they are slow here) there is a guy that has a BH 3.0R in NZ. Let me know.

[chuckthefuk]

You want me to be blunt....

There is no CHEAP way to make 300BHP.. I don't care if you got a EZ/EG long block for free.. The money comes down to these two issues:

1) Wiring.
---> Engine to body harness
2) Transmission issues
---> AUTO to Manual


As for the Rad issue with the EG33 you must check out StarGSR's thread

Cheap-ish easy way to make 300BHP is to find a cheap Legacy SS EJ22T or whatever you call that engine code. Slap the entire engine + body harness and splice into your BK/BG legacy accessories. Upgrade the turbo manifold + 3" straight through + Stage ? ROM Chip + Upgraded intercooler. This should cost you under $5000 in the end including mods but the man hours will push into the 100's. But your OBDI so your limited for diags and such.

Oh yeah, I've been reading up on Lunch's EZ30 and Stat's EG33 build for a while now. I always like the idea of being able to run a bigger turbo with quicker spool times to haul out of corners. But I don't like the idea of putting my rad in the firing range of road litter.
Well, I guess that makes the EZ30 out of my range of experience. I guess an easy way to keep the OBDII would be go with EJ25D heads and ECU, mated to an EJ22T shortblock. But I'm not sure if the heads will take boost well. If they can, I'm sure I know where I'm headed. Or I found a Ver VIII 6sp. swap near my house for $4500 complete (minus the drivetrain after the transmission). I guess I'll just do that, but I want to keep my OBDII.

[chuckthefuk]

Road Litter? Theres a grille, bumper beam, bumper cover.. The only openings are the stock ones. This is of no concern to anyone.

You want quicker spool times .. install a low shot nitrous setup. Most of the big boys with T80 or higher use Nitrous to quicken spool times. So for a VFxx series turbo or a big 20g a 5-10 shot should speed things up if you impatient.

$4500 is a great deal for a v.8 swap.. Keep in mind that the rear hubs + axles + R180 diff is going to run you almost $1500 depending on how you source it.

Up here the motor goes for $4000. Trans for $2000 and rear end for another $1500.


Just keep in mind your getting a EJ20x not a EJ25x

Cheers

Well I was thinking about rocks kicking up but later I thought "mesh, duh". So that's not a problem. The thing is will a TMIC get 300bhp efficiently? Clearly a FMIC wouldn't be a sensible idea with the radiator taking it's space up.
Oh, and I live in Brampton by Hwy 7 and Dixie. I guess I should add that to the profile information. So the Ver. VIII swap is $4500CAD. So I guess all I have to worry about is the rear drivetrain.....
But a 20G? I was only looking for 300bhp so an E316G should be good enough. But yeah, the shot idea is good. I'll use that one.
Well hey, this conversation has trailed too far from the original topic so I'll repost under forced induction or something if I have anymore questions. Thanks alot for everything though guys!

[mike-tracy]

Or you could just start with an EJ257 Shortblock... :smile: Hey I thought your goal was 600awhp?

[chuckthefuk]

.. I live in Brampton by Hwy 7 and Dixie. ..

Check out www.torontojdm.com (http://www.torontojdm.com)
Good prices.

There are many importers in the area some are in Brampton some in North York most in Scarborough.

Anyways if you wana shoot the shit PM and what not.

[Wangan Wagon]

Well the goal was 600, but I figure that I need to start small to get the ins and outs of scooby tuning. Then if there was a need to shoot higher, I would follow through.

Oh, and Chuck, I shall.
