I'm headed out to do a few more data logs, I'll post a dyno plot soon.

Correction. I had been doing all my logging in 3rd gear while I dialed in the OL fueling. This morning I did 2 data logs in 4th and I am pleasantly surprised. I saw full boost (22 psi) at 3600 and 3800 rpms. I saw 18 psi at 3400 and 3600 rpms. This is very comparable to my old Dom 3 but should be able to push a ****load more air once I get a block to support it. Me happy

psshshhhh your dom3 efficiency isnt in the 30psi range like this turbo bahaha. yea once you can get a block thats capable of pushing more power, crank the boost up. you have a 7blade version right? but 36-3800rpms? thats amazing spool for the turbo size

^^^^ True, very true. I can't wait to see how it does with more boost.

Yep, 7 blade. I'll do some more testing this weekend but as of right now I am damn pleased with they way it performs.

now we have a 08+ WRX 32bit SD rom with LC/FFS and CEL flash for knock. and ignition Cut coming very soon im told

but dont get me wrong their was some scary times where i thought i had bricked the ecu, because i would flash and then car wouldn't start and you could here the ecu clicking

also merp made a spreadsheet to make it easy to tune. it helps convert your MAF to VE to help setup a general VE table for first start up. then you can log ve and wideband and it will make adjustments to the VE table based on AFR.

Sick, Im sold, must have! Thanks for the reply. Looks like I need to get back on RR and start doing some home work. CEL flash for knock is , and VE adjust via wb02 log is pretty impressive.

Looks like your fuel lines in to the fuel rail block are backwards? Supply comes from the filter and return comes from fpr/

If anyone else is looking to go with a 7 blade HX35W, I've got a good one sitting on the shelf. I was going to upgrade my Suburban, but have decided the racecar needs parts more than the tow vehicle.....

I am looking to run one of these on a stock V7 ej207. I have read through this thread a couple times now and come to the conclusion I most definitely be running a holset. I was thinking of using an HX35 with an 8 blade inducer (52 lb per min) and one of the tim's turbos exhaust housings. I am looking to hit full boost somewhere around ~4000 rpm. What exhaust housing would fit my goals the best? Looking to make 350-375 whp.

It really depends on your Downpipe. Will you have a 4 bolt or Vband connection?

Likely the 3" V-band. I'll also be winding it out to 8k, I'm sure that has some bearing on the exhuast housing A/R. I was thinking maybe I could get the .70 T3 housing from tim's turbos with the V-band connection.

^^ I'm really liking the .63. But I have not tested it at any higher then 22psi boost so it's hard to tell how it will do just yet. That said, I would like to try the .70 just to see if there is a difference.

Tim's is a .63 T3 to 4 bolt that he can convert to Vband, which is what I am running.
Bullseye power makes the .70 T3 to 3" Vband http://www.extremepsi.com/store/prod...roductid=23483

Both seem to be well made.

I would be all for the .63 because response is pretty important too me, but judging by the exhaust housing chart posted previously in this thread:

so i did some math

12cm = .89 A/R
10.38 = .76 A/R
9.63 = .70 A/R
8.75 = .63 A/R
7.75 = .55 A/R

i know the BEP Mitsu fitments wont apply to this because the area inside the housing is different then the T3 so this calculation will not apply. this is for T3 only

but it gives you a comparison where the aftermarket T3 Housings A/R (.55 .63 .70) fall in line with the OE/holsets CM^2 (9 12 16 18).
Seems like the .63 comes out to 8.75 cm while the .70 is equal to 9.63. People seem to be running a 10cm hot-side on the dom 3, which is also a 52 lb per min turbo. I guess I am just concerned that the .63 A/R won't hold boost all the way out to 8k. Thoughts?

^ i would go with the BEP .70A/R. mine on my 2.5 is spooling 18psi on a 8 blade HX35 before 3500 rpm in every gear. Id feel comfortable running it on a 2.0. i was expecting later spool myself but was very surprised with these holsets spool.

check out DSM Tuners Holset Thread alot of good info. they say that a 8 blade HX35 with Bep .70 T3 spools/flows similarly to a 7 blade Hx35 on a Mitsu .55. so around 3500 on 272 cams and faster with stockers. figure a little loss for thermal efficiency because of the head being farther away from the turbine due to the subaru/boxer design. maybe a couple hundered RPM but if you keep it wrapped/coated, im positive you could still spool 20psi before 4k. And with a 8k rev limit your looking at a 4k rpm 20Psi+ power band .


here is a stock longblock 2.0l DSM with 272 cams spooling a stock 12cm^2 housing Hx35 @ 3k rpm on a TS manifold

^ power the fuel pump directly, most pumps its a benefit, with extra flow @ bat voltage vs Fuel pump controller (12V).

true. i can get 13volts instead of 12. but im going to replace the fpc with another one that works and see if that pops a fuse. if it does, im just bypassing EVERYTHING!!

So just for the sake of learning and testing I decided to get the OEM 12cm Holset housing ready to be installed.

I bought a flange ( http://www.ebay.com/itm/180668853821...84.m1439.l2649 ) and I'll have a Vband flange welded to it once it arrives.

Last night I spent some quality time porting the housing and it is ready to go.


I'm not sure how long it will take to actually get it installed, but at least it will be ready.

Here is my comparison between my stock location Dom3 and my rotated HX35. Before you comment, I am still tweaking the fueling, which includes the rich dip at spool up.

Dom3, MBC, 38mm EWG, Perrin ELH, DW 1100cc, 73mm SRI, on e85
HX35, MBC, 44mm EWG, rotated, Perrin ELH, DW 1100cc, 73mm SRI on e85
Same timing curve (12* to 20*) and same boost level 22ish
I think the Dom is a .55 ar and the HX35 is a .63
As mentioned earlier, the HX35 has a whole lot more headroom and probably doesn't even come-on until 25psi. I hope to test it someday soon.

Blue Dom3 and Red HX35


The smoothing on Virtual Dyno is 7, with no added weight

Some updates. Rebuilt my kit, got it all hooked up tonight, and the brackets that come with my Aeromotive rails are drilled wrong or not for 08+ TGV's anyways. The injectors are loose and leaked from the o-rings during boost test. Have to redrill the holes on the brackets that mount the rails to the TGV's. Anyways, not running yet but some money shots just because....

It lives again. This time with -8 sending, 400lph, Aeromotive rails / Weldon FPR, improved up/down pipes, and EL header. Shake down went well I need someone to check my logs though, I dont think Im hitting my target boost. Had to make a new intake and miscelanious IC tubes. Rotated the MAF around 180* from where it was and maybe moved it up/down 1". So my MAF scaling is suspect..... Also I dont think Im hitting target boost so maybe WGDC needs some fine tunning? Overall it seems to run good, knock is good, and AFR is on par with previous.

Did you upgrade your injectors? What ELH did you go with?
