And one additional and potential reason: the consistence of the oil before the turbo and after the turbo is not the same. After the turbo, the oil is a little bit spumy, and this kind of consistence is against optimized flow.
    exactly... if there's pressure pushing INTO the inlet.. it's also pushing it THROUGH the turbo, and out the outlet...? With gravity ON TOP of that? how could it possibly drop to zero pressure at the outlet?

    by spumey you mean frothed up a bit? That would be because it's lubricating a bearing spinning at ridiculous speeds and incredible temperatures, more than any kind of sitting in the turbo? :/

    Wiring

    We have started to wire the engine. We have to wire the 850W BMW Performance radiator, Okada Plasma Ground, Awron display with egnine oil pressure sensor and differential oil temperature sensor, turbo speed sensors, EGT sensors, O2 sensors, JB4, BLUE16 anti theft system, etc. We are also optimizing some wiring due to space restrictions.

    Diverter valve and charged air recirculating

    We will use only 1 Forge Diverter Valve which will be located on the left side (as our K&N Conical filter also located on the left side.) Charged air will be recirculated into the intercooler.

    Painted engine cover with painted intake manifold

    Today we test fitted the engine cover. Due to extra wiring under the engine cover, we need some refinement as well.

    Electric oil pump fitted

    We modified the factory frame and extended it with a frame for the electric oil pump. After modification we have re-sprayed the factory frame.

    Additional oil canester/tank to optimize oil flow

    We have installed a small oil canester/tank between the turbo oil return line and electric oil pump. This canester is feeded by both of the turbo return line.


    Reason for installing this: when you shut down the engine, the electric oil pump also stops working as becaming act as a "stopper/bung" so the oil stays between the turbo and electric oil pump and cannot flow back. Next time you start the engine, during the cold start up session, the oil, which stayed in the turbo (we are talking about 1.5dl between the el. oil pump and turbos return line) will be smoked.


    With this canister after the engine shut down, the oil fills this canister and will not stay in the turbo.

    @VargasTurboTech Is he doing this so the oil doesn't sit? Wouldn't a turbo timer or something work better? This is confusing me lol

    Honestly, you being confused is on par with most of us I think, this is just reinventing the wheel for nothing. I have said in this post over and over again. He is doing all these things just to do them. Adding the electric pump, not needed, now he has to add this tank because his electric pump idea made system overly complicated and now it wont drain after they shut the car off. My gauge is always, are dedicated race cars that people spend millions of dollars on doing things like this because a turbo will not drain. If the answer is no, and you do it anyways. You are doing it just to do it. This is a show car, plain and simple. Its the N54 version of a chromed out low rider you see at a car show. Is it cool, yes, its very cool. But at the end of the day, its a show car.

    First drive around the garage

    After 1.5 years of starting my rebulting session, we had a small trip around the garage. Not much, but we still have a few small things to do arund the engine, not to mention the bodyshop and painting as well.

    It is physics. You shut down the egnine, electric pump stops draing, oil sits and will be smoked by the next engine start. We have learnt this. This is why we use an oil canister. Period.

    Yes. As i mentioned in my first post, this rebuilt is not about huge HPs, but about my PATH, which i walk. However the entire design and rebuilting can work easily with higher HPs than we would like to achive. Period.

    It is my hobby and will be my "overbuilt" and "overcomplicated" DD car. Period.

    But at the end of the day, I am still happy with this.

    To me, this build defines the word "hobby." It certainly doesn't make sense, but if you're having fun, I am happy for ya! And, it's an interesting read! Thanks for sharing this!
