Ok. Received my new turbo kit yesterday and will begin the install tomorrow. The kit has no 02 bung installed and the pictures off their site (I will post a complete review upon completion) shows the bung installed at the header collector. The system runs the Dynojet PC5 with larger injectors, and I plan to run the auto tune module, which means I need 2 bungs. One for the auto tune, one for the AFR gauge. I've seen that other kits (K&T) run a bung AFTER the turbo. I thought it had to be fairly close to the exhaust ports to maintain enough heat, but don't know. Any suggestions as to where to weld in the two bungs would be appreciated. I plan to run a Turbosmart gated controller to allow on the fly switching of the boost level and fuel maps. 7 psi for the wife and kids, 14 psi when the need for speed takes over my soul! Any knowledgable input on anything turbo would be appreciated.

you are correct, my k&t has it after the turbo.

Just some friendly advice ....... List all your questions on paper -- Then call where you purchased your system from and have your questions addressed.

The bung always goes post Turbo - And there is a correct way to orientate.

You don't need 2 bungs - Unless you want 2. You don't need a dash A/F gauge - Unless you want one. And if so - Using just one bung run the Wideband 2.

Don't want to run the Wideband 2 and still install just install 1 bung -- Then run the LCD-200.

Running 2 Boost levels - 14 PSI and your going to have issues .. Unless you build your motor.

Running 2 different fuel maps. Do not run a map switch.

IF you build the pressure table correctly -- One can run at various Boost levels without concern.

I suggest you download their software (1.0.6.4) -- Its FREE .... And once loaded on your computer click on the "Help" tab and read the manual. It's in alphabetical order -- Not in flowchart format so picking out the information takes a bit of time and understanding. You cannot read the manual enough !!

You will also need to install a MAP sensor. You will need to know what type to buy and how to hookup and program the software. You might also look at the new Pti version fo the PCV.

I don't mean to scare you -- But I suggest your doomed to failure unless you work with your retailer on that kit you bought.

Thanks for the input! I'm a over 50 gearhead, so I'm not going into this totally blind. I am tabulating my questions, and have a few fellow turbo enthusiasts to assist me. The motor will have CP low comp. pistons, head studs, billet throttle body plate, valve springs - pretty much everything but rods. Hadn't thought about the other pieces available from Dynojet. I wasn't sure about the maps......I know the PC5 let's you swap between a base map and the autotune, so I was going to build a low psi base map initally using the autotune and then switch to the autotune map in high boost. Thanks again.....keep feeding me info if I'm headed down the wrong path......

According to the instruction sheet for the Bosch UEGO sensor.

"Mount the O2 sensor in the exhausts system at least 18 inches downstream from the exhaust port. If you anticipate high EGT's (over 800C, 1472F), run a turbocharger, run at high RPM for extended periods of time or plan on running leaded race fuel then you must mount the sensor at least 36 inches or more downstream of the exhaust port as all of these can cause the sensor to overheat. On turbocharged engines the UEGO sensor must be installed after the turbo charger, if not, the pressure differential will greatly affect the accuracy of the unit. For accurate readings, the sensor must be mounted before catalytic converters and/or auxillary air pumps. To prevent collection of liquids between the sensor housing and the sensor element during the cold start phase, the installation angle should be inclined at least 10 degrees from horizontal with the electrical connection upwards."
