Hi hope you can help. Im new to the honda family and am after some info on compatability of engines. I have an 85 civic 1500 sohc single carb and im keen on more oomph.Have been offered a twin carb d15 and trans from 91 civic for 400 aus dollars.D16s from early integras cost heaps so can the old carb motors take a vtec head that i could adapt to sidedraughts and dizzy? for a cheap thrill? or would i need d16 motor ,trans,shafts,brakes etc to run vtec in this car? any help greatly appreciated.Any other cheap combos that would fit ? carbed b16 and trans maybe?
