so i just bought a del sol si thats basically a parts car and i want to put the engine in my 91 civic. what all do i need to make it happen? do i need anthing extra other than whats on the del sol? or is it a pretty straight forward swap?

okay so do i still need to convrt it from dpfi or can i use the harness from the del sol?

 

read the faq but no you cant use the delsol engine harness wont work right

 

well ****. alrighty so i was doing some looking on my del sol and it is using a pr4 ecu which i believe comes from an integra. it still runs fin and has v tec but has a random misfire. should i try and gt a different ecu?

 

YES... you will be dumping way too much fuel and VTEC will not work as a PR4 is a NON-VTEC ECU... You are mistaking the intake noise for "vTaK y0"!

 

do a little searching< just did the z6 swap in my 91 rex. pretty staight forward, went with a chipped pcm and conversion harness, si seats. one of the easier swaps i"ve done.

 

alright ive got the engine out of the civic and i have everything i need exept for the conversion harness i believe im thinking of going with the boomslang obdo-obd1 harness, what else do i need? since i have the del sol and everything with it do i still need the distributor wriring harness? and is there a dpfi-mpfi conversion harness that i need to buy or will the boomslang harness have what i need to get the car running. i just dont want to have any janky wiring running my car.

 

READ THE FAQ'S THIS INFORMATION HAS BEEN COVERED THOUSANDS OF TIMES!

 

what model ef civic are you putting it in? if it is a dpfi your gonna need to buy a harness from a multipoint ef, repin the current ecu harness so it works with the mpfi harness. get a boomslang for a obd1 ecu. buy a stock p28 or a chipped vtec ecu with a basemap for a z6.
