I would say 4,000 for a LEGIT b18 and 500 to put it in....

I was gunna do a b18c1 engine swap but now im debating...

h22a
b20

But I say you just swap it in yourself...I have some good instructions and i plan on swapping myself...I am sure if i need any answers along the way people on Honda-Acura or other sites can answer them....goodluck
