by the sounds of it u dont have an Si civic, so with ANY swap u do u will need to do DPI-MPFI change over.shipped from japan.
(JDM)ZC(obd0)= 130 Hp 108 trq use Si 5 speed tranny, not fast, not slow, good starter engine uses stock mounts,
Price=$800 or so
(JDM)B16a(obd0)= 160 hp 111trq need b series into ef mounts, vtec for good top end, lacks low end. good base engine. lots of parts made for it, tranny is short great for N/A. Must get it shipped from japan.
Price= $2500 or so
(USDM)B18a(obd0)= 132 hp 127 trq need b series mounts again. non-vtec 1.8L, good low end power but lacks power after mid 3rd gear, tranny is LONG with low comp pistons, great for Boost.
Price= $1500-$2500 i've seen them go for a range of prices, i got mine for $1600 canadian. but i also see 1 for sale right now for $2800 canadian, depends how hard u look
(USDM)b18c1(obd1-2)= best engine for buck from GSR, 180hp 121 trq. Vtec 1.8L, makes good power down low, and has Vtec for high power, most stock EF's with it run low 14's to high 13's( average). need a B16a or LS tranny to use it b/c it has a hydro tranny. b16a tranny if u keep it N/A, LS tranny if u boost it.
Price= $3000-$4000 depends on how hard u look.
(USDM)b18c5(obd2) AKA type-R motor.= great N/A motor, DONT GO TURBO on it its a waist of the engine. 195hp-121 trq, great engine, very fast, but u pay for it. also need b16a tranny to use it. LS tranny is worthless on it.
Price=$5500 or so
thats a quick over view, u pick what motor suits U and what U want to do with the car, autoX or drag, or just to cruise. we cant tell u what kinda motor u need unless u tell us what u wanna do with it.
Boost= B18a
autoX= B18c5
Bang 4 Buck= b16a
most affordable power= b18c1
Fun...=ZC
also, my prices might not b too accurate b/c im trying to change from canadian $$$ into american so they might be off a bit.
