maybe we should add a plumbing section too...oil lines & sizes , and water lines and locations to tap from if they're water cooled. especiallky for new comers looking at fi.
this is an awsome thread, keep up the great info.

Turbo: forces compressed air into the engine using a fan in a compressor housing that is driven by another fan in the exhuast housing. housing are connected by a chra which cools and lubricates the rotating assembly.

Intercooler: when air is compressed it is heated and that heat can cause detonation. the heated air is cooled either by an air to air, or a air to water intercooler. there are many different sizes for different power and boost levels.

wastegates: the wastegate is one of two kinds, internal or external. both perform the same task, controlling the amount of exhaust that is allowed to travel through the exhaust housing; therefore controling impeller speed and boost. once a set level of boost is reached the wastegate opens and allows exhaust to pass by the turbo and either be directed back into the exhaust after the turbo or vented/dumped in to the atmosphere.

blow off / diverter / recirculation valve: all perform the same task, they vent pressure that is build up under sudden throttle closing, such as durring a shift.

charge piping: used to direct the air from the turbo to the intercooler (hotside), then from the intercooler to the throttle body (cold side). i have seen lots of debates over sizes on here.. but most say 2.25 on hot side and 2.5 on the cold side.

oil feed and return lines: feed and return lines keep the chra lubricated. the feed line can be ran from the plug in the oil gallery on the side of the head behind the coil pack or one of the oil gallery plugs on the back of the engine. the return line should be -10an line or equivalent, no 90* bend right after the turbo. it should be routed back into the engine either through a fitting on the oil pan or the windage tray. do not put it below oil level in the pan, but always lower than the turbo.

exhaust manifold: this is the part that routes the exhaust to the turbo and wastegate. there are a lot of different designs including tubular and log style.

coupler and clamps: on the couplers the more ply's the better. on the clamps you can either use worm gear clamps for lower boost, but i would recommend T style clamps for high.

Has anyone ever used a water-cooled turbo? That's what I will be using and was wondering where to tap into the coolant system at. I thought maybe figure out a way to run it from that crappy plugged up hole in the t-stat housing that keeps leaking, solve two problems at a time.

I have always ran water cooler turbos, its a very simple thing to set up.You just simply splice into a pre exsisting hose.

When standing infront of the car, look down at the radiator. You will see the plastic log thats mounted to the radiator support, there are 2 lines coming from the right side of it going towards the engine.

Simply splice into the hose on the LEFT (in other words the fartherst left of the 2 coming off of the right side of the log)

oh....did anyone do the "heat exchanger" or Water-Water front mount? like the jackson doesnt have one and the PW does? I didnt see that under "intercoolers" even though it's kinda different....lol

if I am wrong just delete this...HAHAHA......

What's the deal with blow-through and draw-through set-ups? Could someone explain the difference in them?

Draw through is when the MAF is before the turbo/supercharger and essentially sucks air through it. In a blow through setup, the MAF is placed after the turbo/supercharger and air is blown through it. Blow through allows you to run a blow off valve, which will be placed after the turbo but before the MAFS. With a draw through setup, a diverter valve is used to divert the boost pressure from your "pressure side" after the turbo to your non-pressure side before the turbo........but after the MAFS.

Ok, that's what I was thinking, but I wasn't sure. I just wanted to make sure I was setting mine up correctly. I was going to put the MAF after the BOV both on the charge side of the piping right before the intake.

What about the DURATEC guys? do we have any options? And what are the weak points of our drivetrains to consider?
