This is going be a long one. You and I are going to start-to-finish build a 1.8 liter Honda B-series engine for 500hp. The block we’ll be using is from a B18A1 which is a 1.8 liter 4 cylinder that came in 90–93 non-VTEC Acura Integras. It originally made 130hp. The cylinder head we’ll be using is a PR3 VTEC head that originally was part of a B18C5 which came in a 94–01 Acura Integra Type R.
