PTE 5031 RLE Dual BB W/Bullseye Housing?

[Shane2GSX]

I'm getting a PTE 5031 RLE Dual Ball Bearing turbo from ImportEvolution and I was just told that they are on back order from PTE until June. I can't wait this long. I've been waiting 3 weeks already. The guy at ImportEvolution gave me the option to use the Bullseye version of the housing. He said that any notice in performance should be minimal.

I don't know what to expect here. I researched like crazy on turbos and found that this PTE DBB fit my needs perfectly. Now with this different housing in the mix, it could change things and throw off what I've been expecting. So my question is, how much will a different housing affect spool/power/efficiency/install?

Thanks in advance.

why dont you check if Slowboyracing or Extremepsi have your DBB in stock

 

[Shane2GSX]

Neither have it..

If the 5031 is what you want then wait cause the bullseye housing has a different A/R ratio. PTE is .63 Bullseye is .55

 

[Apeximprt2nr]

Oh, but they do have it.

I just called them an hour ago, they told me they don't have it. Thanks for trying though..

Where else can I check??

 

[mitsuclipsegsx]

Everyone else was sold out when i bought it, except dejon, try them, and idk might want to check for another turbo, i mean dont get my wrong i love the turbo but even others arent making the power a 50 trim should be, i only made 330whp and ran 12.9. I like the spool i get 22psi at 3700, but people are making these numbers on evo3, maybe look into fp 3052.

For the price of a standard DBB 50 trim, I would spring for an FP.

 

[Shane2GSX]

I checked with Dejon, they don't have them either. I don't know much about FP. I'll look into that, thanks guys.

 

[Shane2GSX]

One question, does the FP Green bolt right up?

Check out Modern Automotive Performance. They don't have all of their turbos listed on their site, so a request in this thread or a phone call may be needed. They have the PTE 5031RLE and as I found out in that thread, also sell FP turbos. They also have an awesome reputation for customer service, unlike some others...

Yes, it does.

Or the Borg Warner S256. Cheaper than a Green or 3052, full boost well under 4k, I've gone 11.9 @ 119 on pump already spinning madly through 1st and 2nd.

Thanks man, I'll give them a call today.

The only other option I have is to get the Turbo setup for a WG on the manifold. I won't have to wait for that one. Only prob is, I don't want to dump the WG to atmosphere, I want to recirc it. So I'll have to hack up my SS MR downpipe. I'd like to avoid that if possible, but if I have to I will. Anybody know if I could get it recirc'd into the O2 housing (from a WG on the manifold) maybe? Or is it too small?

Dont blame that on the turbo. There are other factors contributing to you low numbers. I made 33 more hp than you on the same boost level with a motor that only had 110 psi across the bored.

 

[tbTalonES94]

i ran 12.0@114 on 92 octane pump gas at 22psi with 16* timing and 11.4 a/f. A friend of mine had the exact same set-up as me but had a standard bearing CHRA and my car kept out-performing his.

my set-up was dbb 50-trim, dsmlink, 880's, gm maf-t, comp 101200's, stock head and block with 7.8:1 compression.

he had standard 50-trim, dsmlink, 880's, gm maf-t, 272's, and stock head/block with 8.5:1 compression.

That turbo was nothing but great for me. It spooled awesome, lost virtually no boost between shifts and had awesome top-end. It was the standard off-the-shelf turbo with no porting and an external 38mm tial on the o2 housing. I also purchased the turbo when they were around the $850 range, but if i were to look into buying one now i'd have to sway to an FP series turbo. Like the 3052 or 3065. Even a green. A friend of mine with a nicely ported fp-green with an 8cm turbine housing was running 11.5@121 in his full weight 1g.

i definatly wouldn't put the dbb 50 in a bullseye housing though. Just my .02

Talked to these guys and they dont' have them and can't get them from PTE b/c they are on back order. But he did start trying to push a 50 Trim Borg Warner turbo on me claiming that they flow better and have better spool. .55 A/R. $1099

Anybody know anything about these turbos?

 

[delta448]

The S256 is the turbo I'm most likely buying when the time comes. The only other one I'm seriously considering right now is the FP3065, it has more potential than the S256 but it costs much more especially when you consider all the other special exhaust parts I'd need in order to run one.

The S256 is very similar in size and spool to a 50 trim, but they advertise max flow for it at 55lbs/min. Most 50 trims are advertised at 49-50lbs/min. Ask Steve (Steve93Talon) in particular, he has been running one for awhile now. He can probably tell you much more than I can.

 

[tbTalonES94]

I was flowing 48-49lbs at 22psi with comp 101200 cams via dsmlink. Properly calibrated maf-t via wideband and gm boost. This was on a relatively warm night (75* or so). Had a stock 1g intake manifold, stock un-ported head, stock valves. Un-ported 50-trim. I could have probably squeezed out a few more lbs if i would have upped the boost a tad, and i know i would have gotten more with a SMIM.

delta448:
What do you mean by similar spool?

tbTalonES94:
What 50 trim?

I think that you should check out this thread.

It should be able to answer most of your questions about the S256 better than I could. The discussion gets better towards the end of the thread. I think the general concensus was that the S256 was almost identical to a 50trim, but was capable of slightly higher flow.

 

[tbTalonES94]

I had the PTE BB 50-trim with the stage3 turbine wheel, my friend had the PTE 360* thrust 50-trim with the stage3 turbine wheel. Both with mitsu turbine housings, mine was un-ported and i believe his was slightly ported on the inlet and wastegate area.

 

[Shane2GSX]

^ How did you do your WG setup?

 

[tbTalonES94]

I made a 2.5" tubular o2 housing with a 38mm tial on the o2. Re-routed. Since the turbo was un-ported i had a little bit of creep issues, but not near as much as my stock un-ported evo3 I had. If i would have taken the time to port it i'm sure i would have had no problem with creep.

 

[Shane2GSX]

Well, I wanna do mine off the manifold, actually I have to since they don't have the turbos in that let you run the WG of the O2 housing. But I'm getting people telling me not to use the SBR manifold b/c it comes off the #1 runner and that's bad, so they say.

I swear, everytime I think I have it figured out, something like this happens. Now I don't know what to do.


I wanna do mine like this:
