Ok, lets say im using the b20 longblock with gsr tranny,axles,linkage etc. i get the motor in. then what do i have to do wire with my stock harness? ill be using an obd1 ls ecu as well. also lets assume stock intake mani for now. and then what wiring problems if i put on an ls mani or skunk2 mani? which tb do i use then?? if theres anything im not asking that you can answer too, very appreciated!

i know people have asked Qs about this before but i havent seen any good answers, i see different answers each time its asked. and i did searched through almost every b20 page in the archives too.

you can A: use your vx harness and make an extenda02 or B: get a 92-95 ls harness. you can can use any tb, but you might want to get one with a map on it. have fun

thats one thing im wondering about. im going to use my harness. o2 sensor extension shouldnt be very hard(just cutting stripping,etc). any changes to distributor? and what about the map sensor?? explain please.
