I took out my whole AC system (i.e. compressor, hoses by the radiator, etc.) because i installed my turbo kit. Basically tore up that engine and went with a b18c (jdm). Summer's coming up and thinking about installing back the ac. Would it be a straight slap on because they're both 1.8 liters or will i face some problems puttint it back on?

 

It's all the same, you will just need to add refridgerant again.
