At least you're getting specific updates and not just "we ran into an issue"

Martijn_b · 04-11-2019, 04:34 PM

Amy news on your progress? :-)

Alright just an update from my side - my smoke is solved too.

I contacted MA Motorsports and purchased their kit. Thanks @urban hermit for posting about it here. And also thanks to MA, they are the type of company we all want to deal with. Perfect in communication, quality products and just very helpful.

I didnt use the RB racing pump. They are an oldschool kind of company, and probably more geared towards the walk-in crowd. I live over 5.000 miles away and their communication just wasnt great. So i went to Turbowerx and ordered their TWX300 pump. Its very quiet (even quiter than the smaller RB pump i had). Just like MA motorsports their communication was also spot on.

Wired everything up. I used a relay and the fuel pump ON signal to also turn on the scavenger pump. 500 miles without smoke so far.

You have to fiddle a bit with the power steering lines if you use the factory ones like me. Also the wheel well cover thing doesnt fit perfectly anymore because of the pump. Its fine for now but next winter ill probably relocate it to a better location.

Hope this info helps other users with similar problems

Thanks for your kudos ...
The TWX300 pump is quieter because it is a diaphragm type. Although they are quieter they don't have as much pumping power.
RB pumps are driven by helical gears and are 'industrial strength'
Glad to hear that it is working for you.
The MA-M kit recommended mounting place does interfere with the inner wheel well liner. They removed it on my build to better accommodate the oversize I/C and charge pipes. Looks pretty 'race car like' with the charge pipes showing out a little from the Stillen front fascia.
One last note - if you don't drive the car for a week or so you will get some initial smoke on start up because the oil does drip into the turbo.
I clears up and not to worry.

Experienced that little smoke tonight, it was gone soon after starting her up.

I think this can be solved by mounting a check valve in the system. So far i cant be bothered to do so though.

Just curious but before you put the pump did you have a catch can or were you using the stock PCV setup while seeing smoke?

clamp a 3/8 fuel rated hose to the pcv, drape it over the charge pipe (on each side) and down that little gap in the wheel well. zip tie to an anchor point and run it down to where you can lightly tie it off at the subframe. as for the CCV, its your choice. you can catch can it ( i havent caught anything from the CCV as of yet) or add a filter at the CCV and a filter at the intake PCV take off for extra intake capacity.

the pcv is not the problem at all..

im yet another with a pool of oil (mine being on the passenger side).

ive considered adding a drain plug to the charge pipe down near the IC...

others i know with the aam kit seem to sing the same song...

i might look into a scavenge pump. Its annoying that you spend a good amount of money for a lack-luster product

I know, it's really frustrating. Also AAM doesnt help you in this at all and comes with some BS story about reclocking the turbos. Whilst the turbo drain design is just bad.

Put a pump in, it was about 1k and 1 day of work but all the smoking is over. My intakes are dry too

It's my understanding that this is a common problem with low mount turbos. With the turbos mounted low - the oil return line from the turbo to the oil pan doesn't have enough downward angle to allow gravity to do it's thing - thusly, the oil backs up into the turbo and then produces that smoke as it exits the engine via the exhaust.
Turbos mounted higher than the oil pan return don't have this problem.

That's why Sasha did the Exa pump setup with the initial BP kits. All it takes to appreciate what that thing does is to run the car with the wiring from the Exapump jacked up. You have a whole new appreciation after flushing oil from your intercooler then having to drive around with a smoke stack till the oil burns out of your exhaust.
