Up to this point (with the various EJ pumps) the flowrate has gone up with the thickness of the rotor. The oil pump rotors from the EZ30R look the same as the EJ ones I've seen, and I don't have any reason to think Subaru drastically changed something that was working just fine for years.

The FSM also specs the flowrate. I can only compare it to the FSM rating for the 10mm pump from my EJ25D, but I would be surprised if it's not higher than the 11mm and 12mm pumps, too.

well if you have an oil pump apart, it's really easy to check the lob size and count, major and minor diameters. The EJ, all the pumps keep the same design but change thickness to create the larger volume.

are you referring to those exhaust flanges that were mentioned 3 months ago?
If so I'd love to get a set of those for my EZ30R... I'm going to have to fabricate my own set of headers anyways, might as well eliminate one step and start with pre-made flanges.

yup, those are the ones...the first ones got screwed up a little on dimensions when being cut on the table. I was suppose to get the new ones done but forgot the gasket in MD for my trip home (Virginia Beach).

Yes, I work on vacation

Is there really no tuning available for the EZ30D ecu? I have been searching for 2 days..... I would really like to add a little forced induction to mine, but that can't happen without access to the ecu.

Any help greatly appreciated.

Thanks

Ummm... Any... Who do you plan to have tune it? Ask them cause they may not touch something you might get.
How much boost do you plan to run? If not much just let to ECU handle it it's self.

Planning to run about 4-5psi. Not much, but I don't thinl the stock ecu will take kindly to that.

Not an issue for the stock ECU. Hell you can probably run stock internals on that! If an EJ25D can take that then so can the EZ30D.

In all the research I have done, I haven't seen any one run FI on the stock ecu. Also, the D H6 is map and not maf. Not sure how that would affect things.

That's cause no one boosts the D...
Anyways MAP is better than MAF especially with boost. Rather than projecting how much air will be in the manifold it reads how much IS in the manifold.

What model year did that EZ30D come out of? RomRaider supports some of the ECUs used in the H6 Tribeca and Legacy.

Single port EZ30D is 01-04' the phase 2 D that we referee to as EZ30R is 05-09' and stopped in the Tribeca at 08'. I doubt Rom Raider really supports opensourcing these. Even if so you wouldn't find it working all the well with a swapped car. The immobilizers are retarded and in everything.

My EG33 STi project is going on. My goal is 21-26 psi, pump + Meth.
Tried this engine with 9.0 CR shaved OEM pistons. Tuned till 10psi. Stock heads. Amazing torque. Up to 7000 rpm. Now want to try EG20K STI valves, springs, buckets etc and stock cams. Try 8000rpm.
Can not decide about CR. Tried EJ207 8.0, 8,2 and EJ257 8,5 ratios. Want middle/end engine think about 8.5 - 9.0. What do you H6 community thinking about it?
Have got reply from CP. There are 2 different wrist pins strong and shelf version. What the difference of these both?
Also thinking about long rod + 2mm from ASF Machine. Any feedback? Similar quality to another H-beams?
Look forward to any advice!

So long as you convert from hydraulic to solid buckets my only suggestion is review the motor for 2.5 pistons and just go with a balanced set of 2.5L STi pisons and rods.

Yes, converting to solid buckets.
Do not want to have broken sleeve issue, i think that 99mm sleeve wall will be to thin.

Nonsense! The sleeve wall will be fine!
BTW once converted buckets you can safely rev to 8k! I need to rebuild my EG in my SVX at some point. My plan is stay NA but 99mm bore and head work.

oh people knocking of the long rod with +2 rods

If you want to long rod it and make a true monster, I'd sleeve, get customer 99.5mm pistons, run a longer rod and I'll leave it really generic for now. I'll just let you know, they don't have an issue with 9k once you sort the head out. Also don't be suckered into buying Supertech's valves for them.

I say this route as going the stroked route for the EG33 isn't a pain to simply gain .3L but loose RPM (flow rate).

any facts? EJ257 like to crack with +1mm bigger bore. Eg33 wall thikness is about 3mm, if i'll go 99.5mm, the wall will be twice thinner.
Homemade
People are starting to knock with a lot of your help)))
My build budget is a way more out. The main point is to build strong short block. Have got for cheap 2 sets of 20k heads. Valves, springs, buckets should fit EG33 heads with a minimum fabrication. The same thing with bigger bore, additional displacement will follow additional headwork and aftermarket sleeves.
What do you think about CR and wrist pins? Going to make the machine work as on the pic.

yeah, you can go to phase two dohc valves and run BMW buckets (or rebore for other size buckets). You then with the longer valve stem have the base cirlce decreased with your reground cams. While at it, have a nice lob tossed on there

You then have all the options of the newer valvetrain for valves, springs and retainers.

For the cost, I'd honestly stay with stock bore, long rod, build the heads for RPM and let the boosted 3.3L run wild.


If you want to drop coin, we can make it 3.8L fairly easily...with more $$ for a billet crank, I can get you over 4.0L...though I'm not a fan of stroker cranks for many reasons.

You've got that backwards. MAF measures the actual mass of air entering the engine through the sensor. MAP projects how much air is entering the engine based on the pressure in the manifold and the density of the air, which is based on the temperature of the air. Unless you over-range the MAF sensor, MAF is much more receptive to increased air flow.

That's what I was saying. I was just wording it in terms of what is in the manifold vs projecting what will be in the manifold.
