Hi there, i've got a rb20det for my KAT setup, i need to figure out the pinout for it. I tried to search the web but couldnt find one. Guess its not a popular swap cause it max at 310ps.

And the tachometer pin on ecu, i try to trace the wiring diagram but was really confused. Someone told me is Y/R, but there are a few lines which is Y/R too.

A is blank, B is signal, C is ground, D is also ground, and E is hot. F is blank

Why did you pick the RB20DET MAF? Did you get it cheap or something? Just curious.

In my case I got one for 12 bucks shipped, and I dont see a turbo upgrade coming for awhile and it should be great for the stock turbo.

24zer0: rb20det MAF only has 5 pins, unlike 300zx with 6. Rite? u posted 6 pinout.

Btw, mine is a 80mm
