nothing in this thread makes sense.

if you have a b20 in the car, why would you get rid of it?

if you don't like the quads then change that, if you like A/C then put it on.....

why would you go from a 2.0 to 1.8

You say that its big hassle to engineer. I ask you....... whats more troublesome.

build a b18 from scratch, buy all peripherals, install, tune, register......

or

just change out your quads.


i don't understand your logic.
