if i were u i wuld jus go for a b16, yes the gsr's an ls/vtecs are better but look at the price difference.. the b16 in my book is a hell of an engine for a 1.6 liter.. i have the b16a2 in my crx i love it, it only has 10 horses less then the gsr an the other b-series are more money.. i think imma keep my crx all motor to eliminate alot of problems a turbo wuld mostly bring
