To site but have read many a days worth of forums from here. I have a 99 integra gs coupe that the b18 that was init the crank pulley bolt spun out and wedged to where it couldnt be unstuck and a great friend gave me a b20b short stroke high compression block with a itr head (the better of the 2 itr heads built) and a 91 integra 5 speed trans for $400.00. I lost the b18 when i was evicted 2 years ago for doing the engine swap where i lived and they would not let me have my stuff back so for 2 years i have been slowely learning what i have and how to put itt in my teg but finally i am stumped. My auto trans quit shifting so gutted that out the car and installed the manual recently. Couldn't find anyone who had the proper mounts so i baught a .mig welder and fabricated my own. Now im stuck because my b20b camewith a pr3 obd0 ecu for the vtec head and i cant find the w iring plugs to the ecu any where.i have the obd2a p75 for my b18 in the car and am thinking or getting the vtec conversion parts to make my p75 vtec workable and do the auto to manual trick but not sure if i really want to continue my 2 year migraine by getting into the ecu like that but i can notlocate pr3 obd0 female pigtails anywhere unless i buy a new ecu from so.eone online. I could really use some in site on wbat otherz have done in this situation or any thing i can do to just get the pr3 in without me having to singularly plig each wire into proper position on the pr3 and solder them in place with shrink tubing one at a time to get my vtec to co.e alive.
