PH turbo
I came across this when doing sopme research, and was woundering if this is true. heres the post i have found.
The inlet elbow of the PH kit is all rubber and it may be just fine for DD in the 9 psi range, but when pushing some serious boost, it really starts falling a part. After maybe 400 miles at 14 psi, the elbow is almost twice the size now and is prone to tear easily.
Adam at ST has redone just about everything on my PH kit including the inlet elbow to a metal one and the entire turbo exhaust housing, the placement of the intake, the piping, intercooler, and even changed it from a suck through to a blow through. It is fair to say my turbo is now a custom built ST unit.
The differences in the car are night and day and the power the car is going to lay down when finshed next week is going to surprise most. I will be at Irwindale this week taking vids and will post some up as well as some shots of the motor after the ST turbo kit.
On the PH kit with their 76mm set-up, I was making peak boost at 4500 rpm and the new ST set-up should se peak boost by 3000 rpm.

I do not like how the PH kit has the draw-through design either. I would agree with the rubber inlet coupler as well. There are some spots on the exhaust side that I would change but I don't think the placement of the intake/turbo/IC/piping is bad at all.

the PH kit hasnt been draw through for a long time now, my kit is probably one of maybe 2-3 if not the only draw through kit.
shortly after i bought mine, they changed to a blow through for tuning reasons. it requires the use of a MAFia though, which mine does not, all the way up to 14psi so far.
and whats wrong with the exhaust side of things?

A blow-through design uses a BOV which is a blow off valve that makes that swooosh sound, easy way of explaining it, and releases the excess inlet air to the outside.
As the throttle opens all the compressed air goes in. But when the throttle is closed all that compressed air needs somewhere to go. Instead of going back into the turbo and and forcing the compressor wheel to spin the wrong way and causing damage to the turbo a CBV or BOV is used to release the pressure.

@ the OP...
So you pick the one guy who didn't like the kit out of how many kits out there?
I know exactly who wrote that and you should really do a lot more research before taking what he stated as fact.
As a matter of fact, if I recall correctly, every kit he gets becomes the greatest thing out there until he changes shops and then the new place becomes the greatest thing. Just off the top of my head it was...Vortech, PH turbo, Kenne Bell and then Whipple with different shops going from the best to the goat, ie: JDM to PH to ST and now GAS.
Now in your post it looks like ST is the best thing since sliced bread, but research further and you will see he had issues with ST now as well and has since moved on. I have nothing against the guy who wrote that, obviously he felt that way about all the shops he dealt with and maybe someday can find the setup that is right for him.
There are guys out there that were running faster then he was with absolutely NO issues, Fin1 is a great example. Look his car up on other forums, it is a high 9 sec ride using a blow through setup with all the stock kit parts.
Obviously, I am partial to PH. I have went through extensive builds with them and even though I live in MI now I will still continue to go with them. There are a lot of customers like me out there, but do your research using forums as a guide, but not the end-all be-all and then base your conclusions from there.
