Honestly, I was really confused how the connection at the factory location was going to work. But after reading your post, it makes more sense. The expansion tank connection points backwards. You could get it to work probably with the hose with 90 degree bend, but I think the way I have it is better/easier.Thanks so much, and nice work! I hadn’t seen Austin’s thread before, so thanks for sharing.
I was intending to buy an N54 front lower coolant pipe and just use the hot side soft lines that attaches to the lower plastic hard pipe in order to use the routing Turner suggests. However Austin’s/your method is much more elegant and doesn’t require routing 2 pipes in the same direction.
The factory N55 expansion tank branch points backwards towards the bulkhead (as I’m sure you know), whereas the N54 expansion tank branch points forwards (as per Turner instructions). The N55 routing expansion tank branch would be super painful as the hose would have to do a full 180, if not more, to follow that plastic hard pipe.
I have an E88 120d/123d suction hood to get air over to the hot side that I may be able to get to fit with heavy massaging/trimming. I’ll let you know, it’s definitely not drop in though.
P.S. I believe 1M’s use 33 32 6 764 505 for the strut brace, super low profile with a fat head, saves trimming the studs and hitting the cowl.
Very cool! Looking forward to seeing your progress.So what I’m planning to do as far as feeding the hot side intake, I’m gonna take it a small step further and I’m gonna source an auxiliary radiator that’s normally used for coolant on the 335is platform and weld 10an fittings to it and basically relocate the oil cooler since it’s the same base “radiator/oil cooler” used in the passenger fender. With a VTT oil plate and external thermostat. That should have everything bolt up like Oem in the driver’s side fender welll. Then I already deleted my fog lights and have the 335is bumper grills, and what I’m gonna do is use that instead to feed the cold air to the hot side intake. I’m currently doing that now feeding my injen intake since I deleted the stock snorkel with the PR block off plate to clean up the front end. To top the whole thing off my plan as a heat shield is to build or use something similar to the ATM intake setup for the 335D. Only difference is instead of receiving air from the snorkel up top, I’m getting much stronger ram air straight from the front bumper grill which was initially used for the oil cooler. Hoping to have a end result like this ATM intake if you look for a picture of it online
It is pricey. I got a sweet deal from friend. You just need the tank (which is still not cheap!) and the rest of the stuff I got separately. The tee is not the turner install method, I just did that myself mimicking @bahn’s thread.Man I wanted that Turner tank, I just couldn't justify the cost compared to the 335D tank. Does the turner just Tee into the heater hose?
