Hi all. I have been watching plenty of people have success with turbo builds so I have taken the plunge. Now that my turbo has arrived I feel I can start a thread for it. My goal is to build a turbo setup that does not require pulling the head at first, I plan to do this by running conservative boost pressures and e85 fuel. I have spent a lot of time on the MS43 thread and have that dialed in as much as a average human can. This makes the biggest hurdle, tuning, now available. The software continues to progress. I hope by the time I get this all bolted up, more progress is made so tuning is even easier. In this build I will try to save money where possible, however I do not want to cheap out on things that will make or break the build in the long run. As my car sits it is fully up to maintenance standards, is a 2002 330ci, and has a 3.07 wavetrac rear end and ECS tuning lightweight flywheel/M5 clutch. It has a oil catch can to help with vacuum. It also has plenty of suspension parts thrown at it.
I chose to try to follow Hobbits project, but not go as far as he has. He has been very helpful recommending parts. He really pulls off some amazing feats. I have not spoken with them yet, but Rally Road is pretty local to me, I hope they will be able to help as well. I am using some of their products too. With that, I also chose to run a ChinaCharger ebay turbo. I chose a dual ball-bearing gtx3076r unit. It seems like it has decent quality, and only has very minimal shaft play. the only other downside I have found is the turbine housing casting is pretty shotty, should be alright though. I also am using the CX racing manifold, downpipe and intercooler setup. Like I said, save money where I can.
For Boost control I will be running the Innovate SCG-1 AFR/Boost gauge and contoller. This works well with the BMW Logger Software.
RK Tunes 60lb Injectors
HPX MAF Sensor
CSF Racing Radiator (with ecu mod target temp 85C?)
Manilfold wrap and gold tape galore for heat protection
Tial Sport Wastegate (I want to run the dump tube back into the downpipe to keep the noise down using 1/2" pipe and some flex tube)
Rally Road Vanos oil feed adapter and Feed line
Walbro 450lbh Fuel Pump
Fuelab mini Fuel Pressure Regulator
K&N Racing 25 micron Fuel Filter
A single, new NGK O2 sensor in the downpipe for the ECU.
New OEM Coils
PTP Lavs Heat Blanket
OEM manifold Gaskets
--and more to come like eventually a new harmonic dampener, but I want to get it running first. I want to complete this build and run in this configuration for a while, and if I still want too, then pull the heads and run a proper thicker/better head gasket and studs.
My first plan of action is to install the fuel system in the standard NA car. I will likely do this next week. I am in Michigan and it has been freezing, so just waiting for a bit of a thaw. I will post up how I end up doing this, but plan on just putting the new filter and regulator in the same place as the standard filter/regulator part.
My second plan of action is install the radiator, intercooler(just the main part), and the coolant hose adapter for turbo coolant. I plan to run coolant from this hose adapter to the turbo, and back down to the block's drain plug. I also plan to install the new HPX maf and delete one o2 sensor at this time and work out all the bugs in that system.
Then, I will go ahead and put the car out of commision as I install the turbo, manifold, and all the rest of the needed parts. I then plan of tuning it using the TunerPro Software hopefully with a provided base tune and the help of a tuning professional at a dyno.
At each of these steps I will list the exact parts I end up using, their links, and some pics of the install. I really hope this thread will become usefull for people in the future. I will also share all my dyno and tune data so that people have a good place to start.
As of now my most pressing questions are:
Which vacuum hose should I tap for the MAP sensor in the EBC? And what should I do with the vaccum hoses that are currently attached to the F connector on the intake boot?
Is it ok to run the turbo oil drain above the drain plug and threaded into the pan? I realize this will be under the oil level, and creat a long and sloped drain line from the turbo, under the manifold, and to the back of the motor where the oil pick-up is?
How do I set up the ECU to run one o2 sensor and how do I know which wire is which before I make some cuts? My current headers melted the connectors so I will be hard-wiring the new o2 sensor in.
Any air filter or tubing recommendations? I realize there isn't much room to work with. I would like to recirculate the BOV in front of the turbo just to keep noise down if possible, but if all I can do is run a short filter, so be it.
