Don't do it. Anyone who knows me well is aware where I stand on the topic of PTE.

Slightly-higher price tag, but Garrett quality and far more turbine housings to choose from.
Thanks for the response! I see they claim a potential 800hp flow rate on the one you recommended. Definitely strikes my interest. Curious as to how it's flow characteristics with a .82 a/r housing would be in higher rpms in comparison to a gt3582r
 
Not sure on that as this is a brand new series from Garrett- there just isn't enough feedback from users quite yet to know specifics. It's tough to beat a 35R turbine for flow for it's size for sure, though a 74/65mm turbine is a bit bigger all-around than the 68/62mm 35R wheel.

They do offer the same turbo with a 64mm compressor inducer, and the entire GTW series is available in ball bearing for substantially-less than retail on a ball bearing PTE 6266/6466.

Been doing some other research in the turbo tech section and came across some of your discussions. One that REALLY sparked my interest was about holsets and Daves hx40. I've always been a big fan of these turbos since I got into dsm's but hadn't seen anyone putting down such incredible times as Dave. I'm curious as to what you charge for your builds on these. If you'd like to discuss those matters in private messaging instead of here give me a heads up. Tax time is just around the corner ;)
 
Quick question for Justin, [sorry if I'm wasting anyones time I kinda have an answer for some of this but] is the evo X compressor wheel able to be used on a 14b center section, I plan on using a super back rebuild kit so the wheel has the right backing plate, and what cover should I use... an evo 3 cover, or should I have my 14b machined to accept the evo x wheel thanks.
 
@JusMX141 or anybody else that can actually offer good info:

I've got an hx40/35 hybrid I may just end up running if nobody buys it. It has a 60mm 6 blade comp wheel, and obviously an hx35 turbine. My question is, what kind of flow could I expect from this turbo in a 12cm^2 divided T3 housing? How high in the rpm range could it make power?

I know that comp wheel is rated at around 69lbs/min, but will it do that on an hx35 turbine in a divided housing? I currently run a DSM76 HTA with a 55mm comp wheel rated at 59lbs/min, (Michael at FP told me they had people actually loggin low 60's though on well set up cars). That turbo has taken my 3395lb car 130.75mph in the 1/4 at 29-30psi. If I am not going to see an improvement over my current setup, I am not going to go through the work involved to change turbo setups.

Thoughts?
 
@Kapok6

I was seeing ,64-65 lbs/min on my he351 at 35-38psi. It's basically a hx35/40 hybrid but in a 9cm single scroll housing. I went 135 on it recently. I think there's more there, but something is wrong iny setup keeping it down. I suspect it's the intake.

Anyway if I were you and you were going to run it twin scroll I would find a 14-16-18 cm housing for it. It will pay dividends in airflow, with little change in spool. I've seen that first hand on my old setup.

So basically, if a 40/35 hybrid will flow 64-65lbs/min...it's not going to be much of an improvement over what I currently have then..

I don't know that an extra 1-2lbs/min potential is worth all the work going from a bolt on mitsu flanged setup getting me 131mph in a heavy car. I should probably go with a straight 40 or BW 363 to hit my 70lbs/min+ i'd like to see...
 
Best you'll get out of it even with a fairly-large turbine housing (14cm2/16cm2) is probably somewhere in the mid-60's, as Bastard pointed out above. To get it to spool remotely-quick you'd want to run a true twin-scroll manifold, and those can be expensive to get fabbed as well as the need for an additional wastegate, custom-fabbed o2 housing, etc. For someone that does fabwork for a living such a task would be simple but for someone wanting to buy such a manifold already complete it can be quite costly.

The best upgrade for a HX35 is a HX40. All of these HX35/40 hybrids out there don't really have a place on a DSM....especially if you're using the small .55 Bullseye housing on one. But as it sits you'd be putting a ton of time and money into it to basically end up with a setup very similar to what you already have in terms of peak airflow and performance. I believe the DSM76 uses the HTA Red compressor but with a turbine wheel and housing that actually lets it breathe to it's full potential...the only way to get much more out of your current setup in E.T/trap speed is to drop weight- 3400lbs is pretty piggy. :D
 
Quick question, is this an eBay turbo?
it has no stampings so I doubt it's mhi.
I know most ebay turbos are wannabe 16g's, and they usually say turbocharger on them or evo 3 dsm etc.
this one has no stampings on it, well aside from those 2 circular stamps...

I have been wanting to upgrade my 14b on my minivan, but dont want to loose any spool.
I had decided on a small 16g with a 6cm2 exhaust housing.
I put it together using a chra I had machined for a 20g wheel, a new small 16g compressor wheel and a generic ebay big 16g compressor housing that I had laying around. Installed it and it spools like crap and sounds horrible.
Then I realized i needed a small 16g compressor housing.
Does anyone still sell these? I cannot find a small 16g compressor housing for sale.
Should I just go straight to an evo 3 16g setup? I dont want to lose my 14b/6cm2 spool...
What would you do for a small turbo setup? I run a 24psi 14b right now as a daily and just want a small upgrade.
 
Hey Justin, I bought a JB fp black during the tax time sale mostly because I saw the evo guys doing awesome with it, well everything I see is telling me that the MHI housing sucks and the 8cm is too restrictive for it.

Is there a different turbine housing I can get or maybe some sort of magical porting I can do to see better gains and performance out of it?
I see FP really pumps up the lb/min rating of it, is there any way to actually achieve that?

Small 16G in a 6cm2 housing is going to surge with boost above 18psi or so depending on the setup. It's just too much airflow being delivered too quickly for the engine to handle. You can potentially damage the turbo surging it like that routinely- which is the reason the Small 16G never came with a 6cm2 turbine housing offered.

You can't use any wheel in a housing it's not designed for- to run a Small 16G compressor you'd need a Small 16G cover for sure. The proper upgrade for a 14B at the boost level you're running would be the Small 16G in a 7cm2 housing.

Everything I've seen from that turbo in regard to spool, airflow, and total horsepower production on DSM's has been quite disappointing. I believe that's why you see so many for sale that are either new or have very low mileage.

Any larger a/r housing is going to cause even more lag but would aid in airflow, but there are no larger DSM-flanged housings available so you'd have to go T3 at which point you would've been better-off to buy the turbo in it's original form (HTA3582R, now called the 71-64) and not have any issues with airflow production or thrust durability at all. The HTA3582R is likely where FP achieved the Black's airflow rating being that it uses the same compressor on a better-flowing turbine wheel and housing then just carried that rating over to the Black.
 
Anyone able to tell me what Garrett turbo this is and where I could get a rebuild kit if available? Was told it was from a Mitsubishi Fuso diesel..

I have a PTE 5031E and am wondering what a good compressor upgrade would be. I was looking at a 3076r with a anti-surge cover.

Garrett GT2560 from an Isuzu NPR. Any "T25" rebuild kit would work.

That turbo doesn't need a compressor upgrade to perform. In stock form they're a 48-50 lb/min unit, and that's about all the turbine housing and wheel are going to limit you to anyway. Any additional compressor is going to find the turbine restriction sooner and add unwanted lag, so in this case it's best not to try fix what isn't broken. There are revised billet wheels available for these but I don't know if they'll fit behind the Precision compressor housing or not...some extended-tip wheels will rub.
 
Absolutely nothing special...46.5/60mm compressor on a 53/47mm turbine. Overall it's smaller than a Small 16G.

You should consider replacing the compressor if you're planning to run it...there's some pretty hateful blade wear on the leading edge of the compressor inducer.
