Custom turbo manifold interest?

[yudkib]

for what though? you can get a fully built PAR tranny. Its not cheap but its pretty dam strong and you can get individual gears too.

its not like the SRT4/STi/EVO trannies are insanely strong where it would be worth doing a swap.

PAR has its own issues, and is NOT meant for a street car unless you want to spend hundreds of dollars a year just changing gear oil.

we are only limited because of our transmissions, if someone would take the time to find one thats close enough to build an adapter plate and make it work it would be a huge discovery in our communty.

thats what i was referring to. for most of us though par gears cost to much, and dont u have to change the tranny oil every engine oil change?
that adds up to be alot like yudkib said.

It looks great, it won't work with my current setup:'''(
I'm running a GT28 with ewg

thats the setup im going to be running. So you will be good

 

[SprNater]

How are things going? I will be on board once they are ready, hopefully for a t3 flange.

 

[95blkprobe]

im interested as well, def in for a T3 and EWG setup. i hope the downpipe will work on my car fine, if not, i can always figure something out

 

[sen2two]

I did a test fit of the manifold, and there was a slight clearance problem. I'm working that out, and i'll have a running test model of fatti's car soon enough.

T3 flange will be an option.

 

[sen2two]

I got a few PM's to what a "T3" flange is... NOt everyone knows, and we all start somewhere. So here is a short description of what it is.

-T3 means that it fits the T3 series flange. It basically refers to the size of the flange. The stock GT25 on the MSP has a T2 flange, which is obviously smaller. Larger turbos have T4, T5, and T6 flange size. Many people think that the T3 (or T whatever) means the size of the turbo. It actually has nothing at all to do with the size of the turbo, but just the size of the flange.

*Not all turbos are designated with T and a number. Only Garrett, and Garrett like turbos. ie; company's who use Garrett turbos, modify them, and re-badge them as there own.

This description could go on and on into a more detailed turbo discussion. But I'm sure you understand what T3 means now.

 

[yudkib]

t3 is also a turbo, but in this case, its referring to the flange on the turbo.

GT2554 (stock), GT2560, GT2860 (disco potato), GT3071... all T2 flange.
T3, T3/T4OE, GT3571, etc... t3 flange.
(correct me if any of those are wrong...)

 

[sen2two]

t3 is also a turbo, but in this case, its referring to the flange on the turbo.

I'm not trying to argue. But T3 is not a turbo, nor does it ever refer to the size of the turbo.

The other numbers... GT30, GT28, GT40 ect. refer to a series or type of turbo and sizes. But those numbers still do not tell the size of the turbo.

 

[43975]

you make a valid point cause my GT28rs is a quiet a bit larger then my Stock GT25
But what flange does the GT30 have??

EDIT:
I see that the GT3071R that PG sells has been configured to fit the MSP mani. They make it a point to say it has the T25 flange.
So unless you order one preconfigured the GT30 series is going to have a T3 flange.
Is that right??

I that's the case case why don't you guys just order the pre configured turbo from PG and save the hassle of having to have a custom flange added??

 

[SprNater]

I bought one of the the old begi/flyin protege turbo kits that came with a t3 system so thats what I have been working with. Dont want to switch turbos as current one is still running great.

 

[justanothermp5]

wow, i never thought of it that way, it does make sense though, so how do u say what size turbo you have? the size of the comp wheel?

i believe its the trim level??

 

[95blkprobe]

the hotside and coldside a/r #'s and the trim is the sizing of the turbo, someone correct me if i am wrong. im fairly new to turbos

 

[sen2two]

The trim is just the difference between the inducer and exducer of the compressor or turbine wheels them self's. The A/R of the turbo, wich MOST people refer to theres turbos "OH, hey... check out my T70 turbo" or "im runing a 60ar turbo...im cool". But really, the AR plays a small role in the turbos job. It does have its role though, but the main ingredient in the turbo, are the actual compressor and turbine blades... (explaining the AR will take a while)

I always refer to my turbo by the size of the exducer (or larger part of the blades) on the compressor (cold side).


**The inducer and exducer are reversed on the turbine (hot side). So the larger diameter is called the inducer.

 

[95blkprobe]

ok i got it now. why do engineers and others have to make things seem more complicated than it really is? haha

correct, the best way to specify the "size" of the turbo is the physical dimension of the turbine and compressor.
A/R deals with the ability to spool (laymans terms: build more boost at low RPM or high) due to the size of the turbine inlet vs. the size of the turbine wheel. the actual explanation is definitely complicated.
trim deals with the ratio of the size of the turbine and compressor.
multiple turbos are generally available in a single "family" of turbos - i.e. gt2860rs has a .48 and a .63 A/R or something like that.
probably the most common way to specify a turbo is the family, trim, and A/R. e.g. - the turbo i'm getting is a t3/t4 (t3 turbine t4 compressor hybrid) 50 trim .43 A/R. (at least i think its a .43...)

 

[95blkprobe]

how are these coming along? im anxious to hear updates

 

[Valk]

A/R just refers to the cross sectional area of the housing divided by the radius of the center of the flow path in the housing to the turbine spindle center. which if you take the measurements at different points all the way down the housing, the a/r stays the same. =)
typically, larger flows more air. implies less restriction, which gives you better revability up top.
I wish there was more information out there on just turbines. been trying to read up on turbine stages and how they come into to play but found limited resources.

I found a great short resource at www.turbominivan.com/tech/turbo201.htm that lays out most of the basic turbo specs if anyone is interested.
