■"Maximum Boost" by Corky Bell
■"Street Turbocharging" by Mark Warner - (Full-Race contributed to this book)
Honda Motor company designed the lightweight low-friction "R-Series engines" for excellent fuel efficiency/MPG, low emissions, and long life. Found in 2006+ non-Si Civics (R18) and international Accords and CRVs (R20), the R-series cylinder head features an integrated exhaust manifold for maximum exhaust heat energy and "fast catalytic converter warmup". The downside to this cylinder head design is poor "All-Motor" Naturally-Aspirated power ... However, the upside of this design from a performance enthusiast perspective is it's perfect for a turbokit: the increased heat energy which normally helps to warm up the cat faster - now helps spool the turbo faster (which is just fine by us turbo honda afficionados).
