B16a2 (automatic) swap help!!

hey guys i have a 97'civic ex.(auto) and i am going to do a b16a2 swap..but im keeping it auto. there are two (SiR2) motors A.is obd1 & B. is obd2
now i know i will have to make a custom tranny mount but im wondering if i get the obd2 motor will i still have to go through all that wireing? i know if i get the obd1 i need a obd2 to obd1 conversion harness($250). but has anyone done this swap with an ek? i need to know what im in for. but ive heard it's a pain in the butt. but i havent heard anything about people doing the obd2 version though. but they say the only frustrating part is the wireing is that true? Thank's guy's

has anyone ever even done this swap?

If I were you id just get a 5spd. As for OBD, 1 is more tuner friendly, but your car is OBD 2 so Id stay with that for simplicity. Usually when swapping you want to stay the same year or newer.

yea but it's a dd and it's not realy towards performance just a nice little upgrade from d16y8, plus when my wife cant drive a 5speed...lol but i know i can use the stock wireing harness from my sohc vtec, and i gotta extend some wire's i guess for vtec and knock sensor's. but im not sure about the tcu(or is that just with an eg) ive been told i shouldnt have to mess with the tcu?? and also just need to figure out how long the swap should take w/all wireing and motor install. but if i skip anything or leave things out then let me know but other than that it should be a pretty easy swap.
