ok i got ahold of a 93 cherokee, buddy is parting out and said i can have everything i need for $150, will i also need throttle cable,trans kick down cable and anything else you can think of i need to grab while im there? also will i keep my same setup with the serpintine belt or will i need to change everything over to v-belt?
I have not followed on this build for a while now, so I will be in the dark on some of this.
I have performed an EFI conversion on my '88 4.2L by using a PCM, wiring, and fuel system from a '93 4.0L HO XJ. This is what I have learned in the process.
Are you using your 4.2L block? Are you going with the serpentine system or are you keeping the V-belt system? The reason that I am asking is this, The 4.2L engine is externally
balanced, meaning that the flywheel and the Harmonic Balancer are weighted
. The 4.0L engines are internally
balanced, thus the flywheel and the harmonic balancer are not weighted, they are balanced. If you are keeping the 4.2L and the serpentine system, you will need to get an HB from an '88 4.2L that came with a serpentine system. You will also need to use the flywheel from the 4.2L as well. Other wise, you will be experiencing a rhythmic vibration from the motor like I am, which in time will destroy your motor. Unfortunately, I am running an AW4 automatic tranny, so there is no weighted flex-plate for my application that will work (that I am aware of at this time).
Throttle cable yes, but it will have a lot of slack u need to take out,but will work...
Trans kickdown... I dont know you will provably have to fabricate something for that...
Grab anything you think u will need, all electrical, connectors, fuel filter bracket, cruise, vaccum hoses, steering hoses, anything you can really... Better to have it and not need it...
Oh and grab to map sensor off the firewall... U will need that
X2 on grabbing everything that you can. If you have the whole donor vehicle, this makes things a whole lot easier. I ordered a throttle cable for a 91-95 wrangler for my '88. It worked just fine.
