Transmission Swap from Auto to Man in 88 Accord LX
 

I have an 88 Accord carb'd. Its an automatic and I'm wanting to put a man. transmission in it. I can get a tranny out of an accord exactly lik mine (same year an motor). I kno it can be done with some custom fabrication but I want to know if it will mess anything up in my motor or be bad for the motor? Please any info on this would be nice. Thanx
