To Puyukrl: I can say, "Ngam! NGAM! Can pasang V6!"
But reality, and honestly, I don't know. I BELIEVE it should be ok (2.3" inlet) but may be a little loud when revved. Up to you.
Peace!
As you're aware, our lovely MR2 rear brake calipers have a self adjusting piston. These piston will readjust for the handbrakes as the brake pad wears off....
