And dont bother using the 3" top section then 3" metal pipe bend and a silicone joiner, the ribs in the stock elbow end up creating a restriction because they get bent and wont line up with the metal pipe properly, i know this first hand, i spent hours trying to get it work.
I got a 6" bit of pipe had 2 smaller pipes welded to on on a 45 degree angle (one for the bov return and the other for the catch can return), cost me a $150 but if your not in a hurry im sure you can find some one to do it, i then used 2 45 degree silicone bends which i trimmed to length and fit, now everything has a nice clean intake path.
For the rest, if you have a little bit of knowledge go to the DIY section, there are threads in there on how to fit injectors and afm (and you will need a fuel pump if you dont have one) and probably the turbo as well, its all pretty simple, will save you a lot of cash and then you just put it on a tow truck to get tuned.
