    NO. We manufactured full aluminimum DCT oil pan, which helps keeping the oil temperature lower. I dont track my car, just spirited and sometimes heavy street driving, therefore we did not intend to have extra transmission cooler

    1addicts is bimmerpost, bimmerpost and bimmerboost have extremely unpleasant relationship. Many people come here fed up with bimmerpost+admins there.

    I guess the DCT oil pan does'nt fit on the AT oil pan?

    AT has different shape, so it does not fit. Our oil pan fits for e9X 335i, e9x M3, fxx M5/M6. And maybe for new fxx M3/M4.

    Ceramic coating on compressor house, suction and charge pipe

    We ceramic coated the compressor houses, suction pipes and charge pipes. This is a kind of inhouse developed ceramic coating, what we used on the top of our pistons. This coating contains nano gold layer and acts as a heat mirror. Mainly this coating is responsible to mirror away external heat from pipes and compressor houses.

    Custom made turbo oil lines

    Today we are finalizing the new turbo oil lines. We have blanked out the factory return line wholes on the engine and relocate it on the oil sump. We made an Y-return line and an electric oil pump will be connected as well via the return line to keep the return oil flow optimized.

    ^^^ Everything looks real good, just scary if that oil drain pipe is actually touching or rubbing on the compressor hot pipes. On my cobalt it was like that but with the AC line, after a month of rubbing on that it ruptured the AC line. This is oil drain line so if that ruptures and gets hot oil everywhere, that can start a fire.

    Finished with upgraded turbos

    I think we almost finished every small works on our turbos, suction pipes, charge pipes, water coolant lines, oil coolant lines. What we still would like to built in is an electric oil pump on the turbo return oil line, to optimize the oil flow back to the oil sump.
    On the top of the ceramic coating, we put bandage on the downpipes to optimize heat management.

    Garrett turbo speed sensors

    We have installed one Garrett speed sensor per turbo. Speed sensor displays will be installed later.
    We have already installed two EGT sensor as well. EGT display will be installed later.

    Now I am 110% convinced you guys are doing things just do them. An electric oil pump to drain the turbos?? Sure if they are below the oil level. Purpose built rally and track cars used gravity fed drains all day every day without an issue, but on a 500 WHP street car you need to redesign the oil drain system? Also EGT probs after the turbos in the down pipes are pointless, you are not seeing anything close to actual EGT, prob needs to be BEFORE the turbo. I've said if before and I'll saying again, your level of commitment to this build it nothing short of legendary, but it seems pretty overboard unless this is a show car.

    I bet myself, that Tony will be amongs in the very first persons, who will confirm again, that we are over board and he doesn't aggree in this and that... No problem, i am ok with my car and ok with your replies, however in some details, me and my engineers have different opinions:-)

    In this matter Tony, you are completly right, the best place for the EGT sensors are before the turbos. The temperature difference between post and pre turbo could be hundreds of celsius. We are hesitating to put this before the turbo in some specific reason, therefore we screw them after the turbo to start with and later we may redisign it.

    what's your justification for powered oil drain when no one ever does it anyway?

    We look at my old factory turbos and sees oil where (in theoretically you shouldnt) and figure out, that a specific amount of the oil sits as the gravity cannot provide enough "power" to pull out the oil. Our modified turbos are sitting a little bit lower, than factory ones therefore we try to apply an electric pump as well to optimize oil flow.

    i wonder why inlet pressure doesn't just push it all out :/

    N54 can smoke fairly easily... maybe improved oil flow would help this. I like all the thought put into this build.

    Oil pressure is built between the oil pump and oil inlet of the turbo. As oil feedback/return line: there is gravity, which should transit the oil to the oil sump, but we think that this gravity is not enough (even on harder corners) and some oil still stays in the turbo and will be smoked easily. 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.
