One reducing fitting for the engine water pump and the infamous BMW pump (pierburg cwa400) even after seeing the dimensions its still smaller than I expected it to be.
I also ordered a little stand alone controller for it https://tecomotive.com/en/products/tinycwa.html

sooo i think i inadvertently figured out the heating up while cruising was from too much timing possibly? i pulled abunch from where it was stock because stock uses reversion, vvt and the pcv to play with the cruise crap... but was still too much i guess. so i pulled it down into the mid 30sw for timing while cruising and its seems to keep the temp pretty well under control - has been cool out lately and i may throw that fitting on the cabin hvac side of things anyway to force more water thru the engine.
the bmw pump blows away probably 90%+ of the pumps out there away no matter the price range, considering you can pick these up for less than $100 used nothing really comes close, even with abunch of head pressure. they can be controlled with a simple pwm controller for like 15bux off amazon. but the tinycwa controller is set up as a complete engine water pump controller; reads a temp sensor, has a warm up cycle, multiple set points for the pump to maintain, variable speed pwm controlled, radiator fan output trigger, can be set to a constant speed.
I am however wanting to use this pump for my a2w loop. now, im not really trying to maintain a coolant temp in my intercooler loop and the lowest predetermined set point is like 15*C (55*F) for this controller. what would be better for me is to try and maintain a specific intake temp of 55* or so. looking at the temp sensor they send the resistance readings are off from a typical IAT sensor, but i just need to sit down and try to line them both up to see what temp(resistance) i want to maintain and work from there and see how it works out.
i may pick up another one of these pumps to use for the engine at some point in the future

and just noticed you can select 3 different temp sensors....and the gm sensor looks to be real similar between the IAT and the ECT. kind of hard to see but they give you 3 data points for the gm coolant temp sensor that match up nearly perfect with an intake air temp sensor at the same resistance readings. sooo i "should" be able to run it as its designed just with an IAT sensor as the target temp of 15*C (59*F) is a nice intake temp. the coolant will be colder than that most of the time and as the temp rises during a pull the pump should ramp up to try and maintain it
