engine swap?? in my 86 CRX?

I have a 86 CRX with 210,000 miles. when I start it up it seems to smoke some, and I am unsure if it smokes while I'm driving.
I really like my CRX, But I am unsure how hard it will be to swap a fuel injected engine??, or what type would fit under the hood.
if anyone has attempted this or has any advice PLEASE E-Mail me.
Thank you,
Amber

check out the D16A1 stuff in my sig

i'm guessing your crx's not an si. if it were you'd already be fuel-injected. i don't have any real advice for you. i'm actually trying to swap engine's too. i got an 86' crx si, the engine's got 205k on it but it sounds good i just want to upgrade. i was thinking about a 91' B16a. i don't know if it will work but you could look into it. good luck!
