Hey, im very interested on all the stuff you need to do this.. and how if possible??? im going to go and pick up a turbo tomorrow and start this project. i was wondering if you could help me out at all.
you can buy my set up and go from there. you will have a HUGE head start without all the headache and calculations I did for you already, and for a fraction of the price! You have a pm from me.

GreekA4, I'm pretty sure that if he has already made his own set-up, he's probably not going to want to buy yours. How bad for boost would a oval shaped pipe be? I know it wouldn't flow as good due to being squeezed, but in a low boost situation, would there be much of a difference? Just thinking of a different way to save ground clearance

first of all, when i pmed him I was offering parts as well, if he wanted to upgrade and couldnt find any good deals on the turbonetics/turbosmart parts I have, or if he is looking to completely tune it sometime soon. Second, about the oval shaped pipe, depending on the where it is and how much it is squeezed, but for the most part if it is a portion of the charge pipes, then that wouldnt be a smart idea. Either way, in that section it will lessen the I.D. to a degree, and cuz too much air turbulence when air will flow back into a round pipe. If you are talking about trying to get down the firewall, a 2inch I.D. pipe clearly fits. I hope that helps all who are trying this set up now.

was your kit ever running? and did you build any pressure, if so what was the max pressure you were able to produce

the system is tuned to 7psi with the Unichip tuning. Before that I was only seeing 2-3 psi w/o tuning like you are, and rough idle. That was only for a few miles, until I programmed the tuning. The tuning portions still needs a bit more FINE tuning that a dealer can do with a dyno, because I do not have access to one.

Yea but the tuning should effect the boost really, I have my wastgate closed off it should be building lots of boost like that assuming no boost leaks, im going to put the maf up front and run the motor na but with the turbo still on the exhaust, cap off the charge piping and measure the pressure that the turbo can produce like that. that should tell me if there is something wrong with the turbo, if it does make good pressure then I can narrow the problems to either possible boost leaks, or the turbo just doesnt flow enough on that motor to build pressure. Ill let everyone know how it goes.

It would not necessarily be worse for boost and flow. If you have a 2.5" round pipe that you want to replace with oval, use an oval pipe that's say, 3.5" wide and 1.75" tall (just as an example - I didn't actually calculate the volume but just threw the numbers out there for the sake of the argument). That way, you'd have a wider width but a lower "height" to the pipe. If you size it correctly, you could have the same flow volume.
