ez30r questions

[Sgt.Gator]

Does the EZ30 series have TGVs we can delete? Any other standard EJ2XX standard mods to consider? Top feed injectors? Fuel Rail plumbing? GBOD?

Can someone post a pic of the bottom of the engine with the oil pan off, and a pick of the insides of oil pan? I'm asking because I'm wondering if a crank scraper/oil baffle like the Cosworth one would be beneficial to this engine. And a deeper sumped oil pan too.

I was racing at the The Ridge last weekend for the first time in my LGT, the Carousel there is the longest sustained high G turn I know of in the Pac NW. It seems like it will never end! Once we figured the best line I started getting low oil pressure alarms with my STI oil pan and only 1.0 to 1.1G s. With the G forces the 818 should create I'm thinking the weak link is going to be oil pressure on these high speed long turns. Nothing a street 818 would ever see, but certainly a problem for those of us racing them.

It's a two piece pan and holds a bunch of oil, 6 quarts if I remember correctly,

No TGVs. There are two manifolds you could run. The EZ30D manifold is aluminum and is designed to work with a cable throttle body.



The EZ30R manifold is plastic and designed to work with a drive-by-wire throttle body.



There are a ton of pictures of the engine in this thread: http://forums.nasioc.com/forums/show....php?t=1215617

Injectors are top feed, same as other Subarus. I modified the stock fuel rails with AN connectors on each end. You could also make a custom rail.

The case is effectively three pieces. The two primary halves, then a lower section which holds most of the oil, then a very small 'pan cover'. The lower section is both the oil pan, as well as the thermostat housing and the water pump assembly.



Here is the 'pan' itself attached:



You can see the factory baffle in the first picture.

Yes, a bit over 6 actually.. You can put about 7.5 in it without a problem, and that helps a bit in long sweepers.

I have a spare EZ30R block with the lower section, so I can take some more pictures tonight. There is a built in baffle into the case. You could do a deeper lower cover, although that part is pretty low already. I'm not sure how much extra room you would have.

[flynntuna]

Will a combination of the 7.5 qts and an accumulator like accusump solve the problem of long sweepers at high G's?

Sgt. Gator will find out for us!..

I have done a number of track days with my EZ30R without any oil problems.. but PIR doesn't really have long sweepers.

[Sgt.Gator]

I don't know the exact weight difference but it is probably minimal. 260 hp stock plus 40hp for exhaust is going to be plenty for the 818. I will post photos once I get going full speed on the build.

Oh heck yes, TT! That's enough! Maybe not for the 1/4 mile drag racers, but in a road race car that will be extremely fast. My LGT runs in the ST class at 10lbs/hp and is plenty fast. 300WHP with 2100lbs (?) will mean super acceleration and with the right gearing top speeds at many tracks over 170 mph! My LGT hits 140 at PIR and the Ridge, 144 at Pacific, and 156 mph at Spokane. That's with +- 310 AWHP with 3300 lbs. The faster acceleration of the 818 will put those numbers to shame, assuming you can keep the rear wheels connected to the ground. I really can't imagine 400-450 hp being a lot more fun than that.

[flynntuna]

TahoeTim, is this were you got the your headers from?

[TahoeTim]

yep

60 days away from production

[flynntuna]

I'm going 3.6 NA with a megasquirt system programmed by Wayne for fly by wire throttle. Raptor will have headers in 60 days for $400. Done and done.


I might supercharge it eventually, we will see.

My 3.6 is mated to my 5MT and ready to go in the frame. Since I just got the kit last Sunday, I am a couple weeks away from mounting the engine.

How are you planning to run the exhaust after the headers? Is it possible to run it like some run it in the GTM?

[TahoeTim]

I going to stay low and go straight back under the trans and come out under the body. I want to save the space above for a big trunk. Exhaust poked through the rear vent is not my cup of tea. The FFR website photos of the red car with the license plate low between two smaller screens is the look I want.

Jeff it's hard to tell in the pic...does the baffle on the block extend down into the pan, or does it stop level with the block? If it doesn't go down in the pan there may be a need for a pan baffle. Crank scrapers look out of the question. A Cosworth style tray might be useful too.

Bringing this thread back.
Found this series of YouTube videos from mightycarmods.com from Australia.

They install an EZ36 into a legacy, they call it Gramps 11 second car build. It's an 11 part YouTube series that describes the build and it's fairly detailed. Even though they use a turbo and I'm going NA, I found it helpful.

[Samiam1017]

Flynn did you also get the header system tim was having made and if so hows the fit and finsh? doe sit fit in the chassis? thx

[flynntuna]

Yes, I got the headers but haven't tried to fit them yet. Getting a house back on the rental market has been taking longer than expected.

[Sgt.Gator]

flynntuna if you haven't seen this thread on NASIOC it is incredible. EZ30R in a Forester, using a Subaru OEM ECU from a UK EZ30R manual tranny car, DIY center lock wheel conversion, DIY individual throttle bodies, DIY brake calipers, DIY carbon fiber mufflers... This guy has mad fab skills. 98 forester STI (Phase 1-SUSPENSION)-(Phase 2 EZ30R)

[flynntuna]

His skills puts us mortals to shame. Very

[DSR-3]

What is the status of EZ30R installs in an 818- has anyone made it work, and is there a good path to follow re. electronics & wiring?

[flynntuna]

Yes. Wayne has done one with an ez30 that he added a turbo to. On his build thread starting on post 316

http://thefactoryfiveforum.com/showt...H6-power/page8

[DSR-3]

That's not the so-called "R" version (3 exhaust ports, CAN bus, etc).

[flynntuna]

Wayne has another thread on that build ...


http://thefactoryfiveforum.com/showt...he-818-IT-FITS

Sponaugle also is building using h6, though he's been dark for a while...

[Wayne Presley]

Not much difference between the 30D, 30R and 36 are basically the same motor. Just be prepared to make a custom exhaust and a stand alone ECU.

[craigfree]

With the ez30r having three exhaust ports, I'm having a much less pleasant time trying to fit headers between the left head and front lateral link. If using a turbo a manifold would probably be significantly easier. I also had to push the motor .5-.75" towards the rear to make room for the cam phasor. (Further hurting space for the header)

Are you using the Raptor headers?

[DSR-3]

craigfree: would you mind posting some pic's of your install? Maybe including some detail on fit issue areas (phaser). Thanks!

[craigfree]

No longer have the image I wanted, but here is a good view showing where the interference is. Photo is looking aft, so the right cam phasor ( left side of image) is in the perfect spot to hit the cross brace. I have a little over .100 clearance.


Found the clearance photo:


Right exhaust area for snaking a header through:

[craigfree]

This is the level of effort in putting into the exhaust

I'm getting it to slip in, but I might still block the spark plugs to ease life.

[DSR-3]

Thanks for the pictures and heads-up on header design. I look forward to seeing your progress!

[DSR-3]

What flywheel & clutch are you using on the EZ30R?

I just got an (another...) early Christmas present.ez30r-1a.jpg

[Wayne Presley]

You will use the flywheel that mates up to the transmission you are using

[Samiam1017]

does anybody know of any headers that fit in the chassis for the 30r?

[Turboguy]

This guy has mad fab skills. 98 forester STI (Phase 1-SUSPENSION)-(Phase 2 EZ30R)

wow. just - wow.


Not sure how I missed this before. I've been reading through his thread for the last half hour. Talk about inspiring -and intimidating- and jaw dropping all at the same time. Thank you so much for posting this!

[Turboguy]

I have a little over .100 clearance.

Is that the clearance you had AFTER moving the engine rearward?


I remember Wayne having more clearance than that when he initially installed the engine in it's original position?

[craigfree]

Correct. Wayne used the ez30d, which does not have variable intake timing and thus does not have the cam phasor.

[Sgt.Gator]

I spent some time digging into the oil system of the EZ30 and EZ36 in regards to dry sumping them. I came to the conclusion that I could possibly make a DS pan for the EZ30 (Maybe!), but the oil system on the EZ36 is very different from the EZ30 and the EJ series. On the EZ36 the oil pump is inside the pan, not on the outside of the block like the EZ30/EJ25 series. I don't see how it could be dry sumped without extensive engineering.

[flynntuna]

does anybody know of any headers that fit in the chassis for the 30r?

Not sure if any off the shelf headers will fit. Going with a power train that's not supported by the original design is going to come with its share of challenges.

I'm using an EZ36 and have a set of headers for it. Don't know yet if they'll fit without modification yet. I'll have to deal with it when that challenge comes. Fingers crossed

This is a link of someone who built their own headers. http://forum.liberty.asn.au/viewtopic.php?f=16&t=11198

Wayne built his own headers in his turbo ez30.

[Wayne Presley]

Yes, you'll have to build your own headers for the 818 with any of the EZ motors. Not that big of a deal but something to be aware of it.

[Samiam1017]

does the 05 outback have immobilizers and all that bad stuff? my other question would be, I have basically an 07 wrx engine now and have been having trouble with the harness and was very close to ordering the iwire system, but now that I have a ez30r option I may be better off concidering a standalone, so I could go either way with just a engine harness change (possibly). What units should I concider? Ived looked at the infinity system but that's doesn't support Subaru yet.

[Wayne Presley]

I have a system that will do drive by wire, AVCS, and has built in traction control. It's $2950 with the car harness.
