Ok I got my hands on a '90' civic h/b ED chassis with a sohc D14 16v on twin carbs. I paid Â£100 for it. (not alot) But the the cam belt had snapped So i put a cam belt on it and hey presto it runs sweet as a nut no piston/valve touch or bad noise. Now my CRX is off the road having a B16 conversion (yeeha cant wait) and i am using the civic to run about in i put it on our rollers at the garage where i work and its running 87.5bhp completly standard. I want to keep it as a 1.4 (1383cc i think?) i dont want to swap engines. I have a D16a9 (ZC i think you guys call it) kicking about and was wondering if the pgmfi manifold and throttle body will bolt on or will i have to change ecu (is there an ecu on the civic i aint checked) Any how i was wondering what i could to spice it up a wee bit i am making an exhaust system for it soon. I can get manifolds off ebay for sohc Dseries engines will these fit? Because it is on carbs will i have to keep rejeting it every time i do a mod? I cant find a power air filter for it. I know you guys have a D15 on twin carbs in the states and was wondering what things you do to them to get em movin a bit better. Also i have given it a good blat and cant find the rev limiter i was at 8000rpm and it was still reving. For a 1.4 its a little nutter (typical honda engine.) I think i have covered as much as i can hope you guys can help. I dont want any piss taking coz i is a brit stiff upper lip an all that bollocks he he he lol..
