im doin a simple engine swap, 2000 civic si engine into a 97 civic ..do i have to change teh radiator and a/c condensor and axles

you won't have to change the radiator, but you will have to use the si condensor and axles.

i'm assuming its the same for the '98 civic too right?

And what would those parts cost?

You shouldn't have to use the condensor either if you use your old A/C compressor

my bad i mixed up the condensor with the compressor. you can keep the stock condensor on their. if you mean the compressor then you will have to use the si one. also the axles will run you about $150-200. my axles ran me $150 for both, but i had the core.

Actually you could use the old mounting bracket I think and use the old A/C, I'm not sure I have 92 and I had to use a 94-95 Del sol mounting bracket and my old compressor mounted up.

i think the AC is in a different placement in the compartmant...isnt it?...not sure but i think u need the b series parts for the AC
