Precision T&E Billet turbochargers

[kbui]

Zilvians,

Well, I was in the market for a new TS GT3071r turbo and was doing a lot of research in finding if this is the right turbo for me. After all of the search I've been doing, I came across these new development turbos called PTE Billet Turbos. Have any of you guys heard of these turbo chargers? Any experience?

I've been reading about these turbos on the evo forums, and have heard nothing but great things about these turbos on 2.0L. I guess it has to do wit the design of the compressor wheel, and therefore its more efficient, responsive, etc., etc. Oh, and they are ceramic ball bearing. According to the evo guys and PTE, it'll out-spool the TS turbos and out-power these turbos as well.

So what do you guys think? any insight? experience? dynos? graphs?

thanks

I JUST missed the billet pte turbos. I bought a 5457 right before the released the billet 5557. In terms of spool, definitely get a bb setup, cause the journals aren't all that great.

And I'd take evolutionm's account on spool for these turbos with a grain of salt. Evo 9 mivec does wonders for spool. Plain jain SR is not in the same league.

Sounds like you want a 5557 if you're looking for something in the neighborhood of the 3071R. My 5457 has an identical flow rate to a 3071r but isn't offered in billet. The 5557 is the closest in size that you can get in a billet wheel. I'd say the flow on that is closer to a 30r.

57 turbine wheel is big as hell though, I have friends making 500+ on pump with that exhaust wheel. I'd pair it with a decent compressor, otherwise you have a giant turbine wheel and not enough compressor.

If I could do it all over again, I'd do a 5857 billet bb...or even a 6057.

6057 has a 7 blade compressor which is supposed to give a broader powerband, 5857 has 6 blades, more for topend power. I have buddies in the 550whp range on the 6057. (pump gas+meth)

6057 billet bb vs. 3071r. Keep in mind that this is a 1.8.

hmm interesting. a lot more top end versus the 3071r. the hp5557r is the turbo i am looking to get, or even a 5857r. do you know where i can find flow charts for these billet turbos? I mean, the reason i was looking into the 3071r is because of it response and power. i like the fact that this turbo can hit full boost before 4000rpms. is this hp5557r capable of spooling sooner? i guess that's want i am asking, and according to extremepsi.com, it'll make more power?

thanks again

It'll undoubtedly make more power, especially topend, but it's not gonna spool anywhere near a 3071. That 57 turbine wheel is very close in size to a 35R turbine wheel, so eve if the compressor is billet and close in size to the 3071, the turbine is on another level. That's where the lag on these turbos come from...the big ass turbine wheel.

I'd assume the spool difference between a 55 58 and 60 comp wheels are minimal, it's the 57 turbine that dictates the spool mostly.

I know its a few months old but always best to add more good info to a thread thats already going.

I just put a PT5557BE with billet wheel on a KA with our bottom mount and vmount kit. Ill try and get a dyno for you guys. Its just thrust though we didnt opt for the PT5557B-BE dbb dual ball bearing turbo.

If you want to message Caleb (the owner of the red S14 ka with these parts) his name is wannabe1989 on here. Make him hit the dyno haha

I heard a few issues of the billet turbines not being as strong as the cast and breaking apart..

[neukin]

You mean compressor wheel? the turbine wheel is the hot side and as far as i know its not billet, still just Garrett stock part?

[Omarius Maximus]

57 series turbine is specific to pte. Although it's the size of a garrett stage 3 turbine wheel found on your average t series turbo, in profile, it looks more like a gt series turbine.

Here is mine:

vs garrett

kinda hard to tell, but the pte has curved blades, while the t series has straight ones.

[neukin]

Thats kinda interesting, you could be right its a GT turbine wheel.

We just put a 6765SP on a 13B will be interesting. Its the turbo from Precision Turbo is rated at 900hp but with that 67mm PTE compressor wheel and as you said prob a GT series 65mm turbine wheel its going to make some power. Had a GT4082 on the car last year and was doing 450hp and 325lb tq. on 14lbs boost. Was hoping for more power in the mid range and sooner with this new turbo. We ran a 60mm tial and switched to a 46mm Precision wastegate for testing. The boost would actually drop on the top end with the 4082 and 60mm tial.

This 13b should see about 500hp this time, hope we can get her all dialed in. Should have went with the 6265 turbocharger with billet wheel though, this 6765 turbo seems a bit large but rotary motors breath heavy.

Alright well maybe since some time has passed maybe some more folks have purchased and are running these turbos now. I am in the market for a new turbo for my sr20 build that I am doing and have been researching these as much as possible but like was mentioned most info is on the evom forums. Im looking to run around 450whp daily at lower boost levels, say around 20-22psi. But also want the ability to up the power later down the road when this car isn't my dedicated daily anymore. While my daily Ill be running 93 octane and might do some sort of meth injection for high boost levels. Have been looking into the 5857 but not sure if I am going to see the spool up that I am wanting since I wont be running it at evo boost levels of 30+ psi. I am looking to gain full boost in the neighborhood of 3800-4200rpms. I spoke with a guy on the evo forums and he suggested that I run the 6057 but it is discontinued, but you can upgrade the 5857 compressor wheel upon ordering. I have read that the 7 blade design of the 6057 offers a broader power curve then the 5857 does. This same gentleman also suggested the hta30r but I can't really find much on this turbo and have heard that the spool characteristics really aren't what they are cracked up to be over the standard 30r. Really wanting to run a precision turbo as they are priced well and there are plenty of people putting down excellent numbers with very minimal problems with them.

Just looking for anybodys .02 cents that may have had a chance to test out one of these turbos. The car will be a general street terror with minimal track use if I find the funds for tires and fuel. I am a graduate of SAMRacing and just enjoy building motors and cars so there really is no dead on purpose for the car but to enjoy it wherever I go.
Thanx in advance for any and all info that can be provided.

I have a PTE5857 with .63 vband exaust side i made full boost 29psi at 4300rpm. I made 534 at 29psi the car is on E85. The turbo has quite a bit more left in it i coud see it making 600 on 40psi. Its a stock longblock with jwt s4 cams and all the goodies.

[kbui]

juiced350diesel....got a dyno sheet. full boost at 4300 at 29psi!!! crazy dude....stock longblock?

[MandTPhotography]

^ Yeah, holy shit.

[speedfiend]

Holy hell juiced that is crazy. How long you plan on running that thing on a stock longblock? Im sure you plan on forged internals when you take it to 40psi. I too would like to see a dyno plot of that badboy. Since I will be running forged internals how do you think the spool would be at around 25psi on 93 octane? Im contemplating going with the 5857 and having them upgrade the compressor wheel to the 60mm 7 blade since that will offer better spool. Although it will sacrifice a little top end, Im not really worried about that. Plus they say that the power lost is really only noticable upwards of 30psi or so which is probably about as far as I would take it anyways. Thanx for the info and lets keep this thread going with more good info and hopefully some nice dyno plots to come.

WeLl I'm going to the dyno this upcoming week angel aka miami240 is tunning the car. I overreved and snapped a rocker I was spinning my 275 mickys lol...
