Not to say that I am still considering an FI kit for my Z...

yeah youre right, sharif, grd, carv2, (everybod else on this continent) must not be capable.

Your statements are absolutely ridiculous. BTW all stainless piping can rust. Its just surface rust that can be easily removed. But I guess you know that too right?

1. Cheap Steel piping with a chrome plating and unfinished inside welds, are at the least, not ideal for performance. APs uses superior stainless steel on all of their piping and grind each weld inside every pipe smooth for better airflow. We have seen chunks of weld left unfinished, come off inside the piping, a scenario I would not want on my vehicle..
2. 380cc injectors maxed out at over 100% duty cycle at a mere 360 whp
3. Incomplete fuel system consisting of only a walbro 255lph pump
4. RPM dependant reflash, which IMO is simply asking for a problem..
These are a few of the things I feel APS has over the compeditors turbo kit.The end choice of what is and is not a TURD is in the end users eyes and goals.

Um obviously you are misinformed. EVERY Turbonetics part is produced in house. That includes all the machining, assembly, balancing, etc. As for the exhaust piping its SS304 piping. I don't see how this is "cheap". I'm curious what you consider to be good exhaust piping and welding. If you are telling me that their pipes are so bad do you all consider Thermal R&D stuff, DC Sports, Strup, and any other piping made in the USA crap as well? Oh and if the injectors and fuel system are "maxed out" at can you explain how my car did this on that same fuel system: http://members.***.net/w.suarez/350dyno11-15-04.pdf

Let us know how your install goes.

Just kidding...
What are you doing to the interior anyway?

did it in my garage, on jackstands. i bought mine in the original GRD GB, got it shipped overnight, started the next day, before they even got the other ones shipped out. so i was the first to really start installing the kit. ive done all my mods, vortech, brakes, suspension, etc.

As for the fuel system, it is weak sauce..Hook up a consult and datalog the actual injector puls withs and duty cycle, you will find at 7 psi arounf 5500 rpms the injector duty cycle is maxed out and simply spraying fuel from fuel pressure, but they are waaaaay over the industry standard at that point..Your dyno shows nothing, nothing at all...Im not saying the kit does not make power,im saying it does not do it safely..
This rod is from a TN kit with its maxed out injectors running a 13 A/F ratio..

4) the tension on the wastegate is incorrect
5) he has a manifold leak under boost..(wondering if he has a spacer or Kinetix plenum)
6) his BOV is opening under boost and needs to be set..
There really is no other explanation for him not making and holding boost...

Man, relax, I was joking.
Actually this mess is all my fault. I posted that my opinion of the APS ST has improved, a couple of people decided to disagree, now we have an APS ST vs. TN ST round who-the-fugg-knows-what...
I think it's best that be get back on the topic, which is JasiJ being happy about his APS ST install by the MRC, which should be happy be a shop to finally do a fully successful APS ST install.
Off topic, why are you still on the forums during your vacation time? You are not addicted to these forums, are you?
Um have you ever logged FUEL PRESSURE on a properly installed Turbonetics equipped car? It runs less fuel pressure then the APS ST kit does I can tell you that. I see 53-55 PSI at idle personally. Again if you had done some research you would know that the modification to the stock fuel pressure regulator lowers the fuel pressure from the increase caused by adding a Walbro 255 lph. Without modifying the regulator and just installing my Walbro fuel pressure was at 75 PSI. After modifying the regulator its 53-55 PSI at idle and 48 PSI under boost. Which btw is about where it is stock. So explain to me again how the injectors are only flowing more because of increased fuel pressure
BTW the Vortech kit DOES do that as its fuel management but with stock injectors instead. The Turbonetics kit however DOES NOT.
