i have a 94 integra ls now i also have a 96 gsr full motor swap. i have everything for this motor except the harness. i am using a obd1 p28 chipped computer that a guy used on his gsr. one of my friends told me that i can use my stock wiring harness and wire in pins for the vtech and map sensor and what not is this true if so how do i do this and if not true what do i need to complete the swap. also when i buy my full exhaust will their me any problems installing it or will it bolt right in

 

You can use a P28...they dont check for knocks sensors. they dont give you trouble either ...as for the exhaust go's you jus dont bolted on the header ya got to first weld the whole exhaust system then go from there...but my advise to u is before you ask a question RESEARCH IT FIRST!! you can ask anybody here at ht they will highly recommend it to you!! :D good luck buddy !!

 

theres one problem with using the p28 ecu. it dosnt have iab control. so you will need to buy a single stage intake manifold, or you will lose power.

^^he's right the P28 doesnt check for butterflies in the mani the p72 would bc its orginally for the gsr.. so u would have to prolly change mani's..correct me if im wrong???

 

what mani do i need also if i get the p72 can i use my ls harness and wire in pins for the vtech or do i need an obd2 harness

 

also what do you mean about welding the exhaust. what i am saying are all b series exhaust part compatiable. do thay just bolt right up or do i have to fabricate and exhaust.

 

i am pretty positive the header lengths are different between ls's and gsrs so therefore the exhausts are slightly different

 

um if your car is a 94 and the motor is 96 you are going to have to do some wireing since your harness is obd1 and the motor is obd2

 

well i knew that i have to wire some stuff in but like i said what do i wire in and where can i get the wiring diagrams also does the motor just bolt rigt up or do i have to do something with the motor mounts and trans mounts

 

the motor will bolt in and i know you will need to wire the dizzy

 

where do i get the wiring diagrams

 

if u need a p72 obd1 let me know..i got one for sale and a obd2 to obd1 harness
