Where did you get it ? I am doing the same thing with my car only with a bep mitsu flange housing.
Jim.

[steve]

Well guys today I just got my .078 nos jet which will be used as a restrictor in the -4an feed line for the holset.
http://i908.photobucket.com/albums/ac290/stevetalon/03-10-10_1855.jpg

I also just picked up a Tial 44mm vband wastegate for $160:p

http://i908.photobucket.com/albums/ac290/stevetalon/03-10-10_1853.jpg

So I allready ordered the bullyeye bolt on housing and all I need to buy is the feed and return lines, o2 housing, and fab up an intake/run speed density:D

[mitsunut]

Hey Steve, how are you installing the restrictor in the 4 an fitting? I had to do some creative fittings to get the restrictor for a Garrett to work.
Jim.

[steve]

Hey jim I found out how to do this from a thread on tuners
http://www.dsmtuners.com/forums/articles-turbo-system-intercooler/171317-how-make-your-own-oil-restrictor-garrett-channel-bearing-non-bb-turbos.html At my work they have a machine shop so the guy that runs the lathe is going to turn it down for me.

[mitsunut]

Thanks, I will look into it.
Jim.

[mitsunut]

Went to AAI yesterday in Arvada, they have lots of fittings and hose . They took the 1/8" to 4-an male fitting , turned off the taper end and then used a nos .078 or whatever fitting on the end . Cost $5 for the fitting and machine work. Did it while I waited.
Jim.

[biglady112]

You guys did that the hard way.

They also have -3 fittings, which is what I run. But they sell out of them quickly when they produce a set.

[mitsunut]

Yes, but I already had the -4 fittings , hose , etc. Thanks anyway.

[biglady112]

I guess, I just want as little connections as possible in my car. Less chance for failure. I am trying for five miles of hualing ass at a time.

[mitsunut]

I do agree, the more fittings the more chances for leakage.

[racebreakfixrepeat1]

So you ever get that thing mounted up?

[steve]

So you ever get that thing mounted up?

Not yet but hopefully I'll have it on soon:D. Still need to buy oil lines, o2 housing, and the tial vband flanges clamps. Saw you pic on the cylinder loss thread, your the guy I bought it from right?

[racebreakfixrepeat1]

Yes sir yes sir. Well good luck with the project. I'm pullin my motor and I have a full 2.3 swap ready to go in. Hopefully it will fix all my problems. Lol.

[steve]

Check it out I just got my bullseye bolt on housing today in the mail:D

[mitsunut]

Mitsu flange or t4?
Jim.

[steve]

Got the Mitsu

[TerryLiv]

So, help me with this. Is this mitsu flange the one connecting to the O2 housing or the exhaust manifold. If O2 housing what is the A/R of the turbine housing?

Thanks,

Terry

[steve]

Its both the mitsu o2 and the exhaust manifold flange with a a/r of .55.

[TerryLiv]

Its both the mitsu o2 and the exhaust manifold flange with a a/r of .55.

Please tell me how much boost you can use before getting significant missing. With my A/R of 0.63 I start to miss at anything above 30 PSI. I have been told my problem is the too small A/R ratio.

My turbo is a PTE 6162. Same cold side as a GT35R.

Thanks,

Terry

[mitsunut]

The Mitsu flange pattern is where the exhaust manifold bolts on to the turbine housing and the o2 housing is also stock mitsu pattern. The waste gate port is larger internally and the exhaust port opening is 2 1/2" . I haven't been able to boost more than 15 psi so far , still breaking in the engine rings . After break in and bigger injectors I will start increasing the boost level with a 30 psi goal.

[prophecymiller]

I have been told my problem is the too small A/R ratio. Same cold side as a GT35R.

Terry, I was wondering what the reasoning is behind this idea? I would guess the backpressure supposedly isn't letting fresh air into the cylinders to fire? That seems like a huge amount of backpressure for a turbine that size unless the backpressure is purely dictated by the turbine nozzle size (Cloud, do you possibly know?) Meaning that the turbine is large enough, but the nozzle is creating a bottle neck...

It would seem as though the flow would have to completely stop entering the engine, which would make me think the compressor would surge like crazy at the same time. Hehe, don't know if any of this happens but it's always fun to throw around ideas:)

[TerryLiv]

It doesn't surge during the missing. I have not had anyone tell me in detail why, but they say it is choking the exhaust. Fast spool up though and good power up to 30 PSI, then flat and missing.

Terry

[steve]

I just helped my friend take off his ebay evo 3 gt and he got a dbb pte 50 trim so I took a pic of my holset by the two.

[mitsunut]

Holset hx40?

[steve]

7 blade hx35

[mitsunut]

Oh, It just looks a little different with the tabs for the wastegate actuator.

[steve]

Well guys its finally coming together:D Going to race at high school drags shooting for a 12.x 1/4 mile.

O and check out this monster of a turbo I found lying around PFI in fort collins:eek:

[mitsunut]

Looks good steve, did you find a water pipe?
Jim.

[mitsunut]

Terry, I am running 29 psi on 100 oct fuel no miss.
Jim.

[steve]

Looks good steve, did you find a water pipe?
Jim.

Yeah, I went to the u pull it off broadway this weekend and found a non turbo water pipe. Got the turbo one notched kind of like yours but the welder guy messed it up so I ended up denting the non turbo one with a sledge hammer which worked pretty good.

[TerryLiv]

Terry, I am running 29 psi on 100 oct fuel no miss.
Jim.

Jim.

Sounds good. I now believe my missing above 30 PSI was because my wastegate was leaking and not because of the small hot side. I still have the problem of not enough turbo to make more than about 30 PSI of boost though. On cold days I have seen 34 psi. But with the top port pressurized it is steady at what ever it initially goes to.

Terry

[mitsunut]

Terry ,
What turbo are you running?
Jim.

[TerryLiv]

Terry ,
What turbo are you running?
Jim.

Jim,

It is a PTE6162, ball bearing. Same cold side as a GT35XX, but smaller hot side.

Terry

[mitsunut]

Terry , do you know how many lbs per minute it is rated at?
Jim

[TerryLiv]

Jim,

No I don't, but probably 60-65.

Terry

[thiazole]

Jim,

It is a PTE6162, ball bearing. Same cold side as a GT35XX, but smaller hot side.

Terry

But it is the XX part of 35XX that tells us how big the compressor is...

[TerryLiv]

But it is the XX part of 35XX that tells us how big the compressor is...

I have been wrong on this for some time.

I just figured out why I had thought that. The GT3582 has the same size compressor wheel as my PTE6162. Inducer is 61.4mm, Exducer is 82 mm.

Thanks for pointing that out to me.

Terry

[thiazole]

Yeah, the way turbo companies name their turbos is very confusing - I wish there was some consistency at least. Bullseye names their Borgs with the first number that designates the size of the compressor housing (2 seems to be the smallest, 5 is the biggest I think) and the second number is the inducer size. I think as far as HP potential, that the inducer size is what matters most. Exducer sizes can vary dramatically between similar turbos, so I don't know why Garrett insists on naming turbos by exducer sizes.

[steve]

Finally got it running! The stage 4 xtd unsprung clutch grabs extremely hard very suprised for a clutch that was 180 shipped. Whats crazy is I saw 5 psi part throttle in second gear 2500 rpm. Turbo has no lag what so ever and I think it spools as fast if not faster than my t28 lol. Switching to speed density soon and hope to take it to the track:D

[mitsunut]

Steve ,
Glad you got it up and running. You will be more than happy with that holset.
Jim .

[steve]

Thanks jim!

[steve]

Got speed density going and Im running almost 29 psi:D
This thing pulls like crazy. Here are some pics.

[Cloud]

I noticed the stainless ARP turbine bolts... be careful with those over time. They never really worked for me. They would back out and gall the threads off easily. I eventually returned to all new OEM bolts and lock washers and had a much better time.

[mitsunut]

Looks good steve, what are you using for radiator fans?

[steve]

I'm using a single 12'' slimline fan in the front of the radiator. Works great and keeps the car cool.

[steve]

I noticed the stainless ARP turbine bolts... be careful with those over time. They never really worked for me. They would back out and gall the threads off easily. I eventually returned to all new OEM bolts and lock washers and had a much better time.

Yeah I'll make sure I check on them. Didn't know ss bolts could gall threads and it was weird they came with flat washers.Does it help that I did put a crap load of locktite heavy duty antiseize?

[Cloud]

I used anti-sieze as well but I still had issues. I ended up with a warped housing that needed resurfacing to seal. I doubt everyone would have the issue but it's something to keep in mind if it starts leaking later.

[thiazole]

I had the same problem. Luckily I caught it before any damage was done.

[prophecymiller]

Yeah I'll make sure I check on them. Didn't know ss bolts could gall threads and it was weird they came with flat washers.Does it help that I did put a crap load of locktite heavy duty antiseize?

It depends on the type of anti sieze...the Heavy Duty version of Locktite's stuff looks to be good to 2400 degrees which should work...although they make quite a few different kinds and it looks like this particular stuff is metal free? Didn't know they had metal free. I use Felpro industrial molybdenum disulfide which has a very high temp. rating...a friend of mine uses a very expensive nickel anti sieze that is supposed to be the best. Even then, it doesn't always work in a turbo application.

I would put in stock bolts and washers as they are high grade, hardened, high nickel content bolts...not going to get much better than that even by going with some expensive stuff like ARP(now that I think about it, the ARP's may be cheaper as the stock bolts are quite expensive).

[Cloud]

ARP is actually cheaper. The oem bolts are hardened and arguably the single best fastener for the application. Stainless steel is not the best material for a fastener, especially not at higher temps, and even beyond that, especially not when mixed with other steels/irons that have different thermal conductivities and expansion rates.

You can get silver and copper antisieze that is rated for 2000+ degrees pretty easily at napa and the like. It's always a must, but even still I could never hold the arp hardware together.

All in all I think fresh hardware for the turbo cost me about $70 including doubled up lock washers and was worth the money.
