LS into 93 Civ Question

[Fabricator]

Hey every one, Im sure this has been asked before but i cant get any diffinative answers.....Ok so im putting a 97 b18b into my 93 Civic ex. I got the complete swap from local yards an pieced it all together. I have a p28 in my car now. i hear i need a pr4 ecu to make this work? I also hear i can use my p28 to run this if its chipped? I have afc, unlimited dyno time ect. What are your ideas on this? Just get a pr4? Anyone using there p28 to run this setupwith out a chip ? If i need to get the p28 chipped where do i find one of these chips? I have the complete swap, but i know im putting an obd2 engine in an obd1 car, which engine harness sould i use i have the obd2 that came on the engine and obviously the one thats in the car now. And finally what do you do with the throttle cable? Custome bracket or a 94 ls throttle cable? Thanks for all the help to a new honda guru. And Seriously look for some big Stock Block w-Boosty numbers for this baby this spring. Im going do do some software platform testing for yall to benifit from....

Use the pr4, the p28 is a sohc vtec that you wont need, sell it unless you plan on vtec later. Use the LSthrottle cable too..

ya, thats what i would do, and you can use your civic harness, it should work, cause the one that came on the engine is obd2 and not all of the plugs will plug in. you would need a obd1 distributor also unles you want to change the obd2 one to fi your car.

not all this apply's too you but some of it should help i just copied it from another thread i posted this on!
-OBD1 engine harness(Not obd1 92-93 integra doesnt work trust me)
-OBD1 Alternator
-OBd1 injectors
-OBD1 DIzzy
-OBD1 ECU (p30,P72) or if you cant find a vtec one for a good price pick up a stock eg ecu so you can Drive while looking for a good deal on one!
-Integra 94+ mounts
-i would replace the timing belt,water pump,tensioner,cam seals,headgasket if i was you since the motor is already out it will be sooooo much easier

Right on for the Mount Pic Yo.....Yeah while the engines out i already am doing t belt w pump front and rear main seals ect. So What do you mean by changing the obd2 distributer to fit? Im guessing the plugs are differant? As well as the Alt? Thanks for the help dudes Anyone want to trade the p75 that came with this thing for a pr4??????????

[Civic-8442-]

why would you wanna change ecu's the Pr4 is the same thing as the p75 kinda its still OBD1 and thats all that matters

[Fabricator]

it wont plug into my harness

[sirtef9]

it wont plug into my harness
What won't?

[Civic-8442-]

If the p75 is not pluggin in (straight in) then that must mean its a OBD2 ECU man and your SOL! you need too find a ecu thats OBD1

[Osiris92EG]

get a P75 and an OBD2 harness.

[Civic-8442-]

get a P75 and an OBD2 harness.

he has a p75 obd2 already!

hey man u can just buy a harness jumper thing! that converts obd2 into obd1 accessed ecu

[Fabricator]

i supposedly have a pr4 on the way

[sirtef9]

pr4 for your 93?:confused:

[Fabricator]

Ok so the ECU didnt come So i still need to trade or buy one cheap. no chips

[daBoosted93]

pr4 for your 93?:confused:

whats wrong with that? pr4 came in the 92 and 93 integra which is obd1, what he needs.
