This engine made 160hp with 2.0liters of displacement. This engine is VERY rare, VERY expensive, and very hard to find parts for. How expensive you ask? Restored valve covers (with the wrinkle coat redone) can sell for over $1000.
I can't see putting one of these unobtanium engines into a roadster, or non-Skyline (or 432Z) application-- they are just too rare, and too expensive!
Just think, you can get your 160hp (real HP, not 70s' Datsun mystery HP) from an S14 SR20DE for the price of a restored S20 valve cover!
