Alright guys and gals, Santa came a few days early this year and brought me a 5.7L V8 HEMI from a 2007 Grand Cherokee. I must have done something good to deserve it!
Besides, I always wanted to start a new thread with this title!
This will be a slow build due to time restrictions and mechanical inexperience. I'm a complete NOOB but hard-set to do something about it. I have never attempted anything like this before so I'm hoping that with the help of a few friends and JF this can turn into a great learning experience for everyone involved.
This engine came out of a 2005 WK which was bought by the previous owner at a bank auction. It was a good deal and he bought it with 25K miles on the clock. He was a hardcore offroader running a YJ on 14-bolt axles and 44" boggers, so he needed a powerful engine to handle the job. He pulled out the entire drivetrain and fuel system from the WK and bolted it onto his YJ. The ECU never knew the difference as he used the WK's gauge cluster. After some hard offroad use, the WK's transmission got fried so he beefed up the flywheel and clutch of his YJ's original AX-15 and used that successfully without any failures.
Eventually he was forced to drop the extreme offroad sport due to the "wife factor". He's got a Nissan Patrol which he still uses as the occasional offroad/hunting vehicle so he no longer needed this monster. Several people offered to buy the YJ complete but he turned them down as he didn't want someone else driving his baby. He decided to sell it in parts and that's where I came along.
Check out a couple of action videos with the HEMI in the YJ running 44" boggers.
Several people have asked me why I'm doing this without previous experience or much mechacnical knowledge. Here are my answers:
1) I know how to turn a wrench, so why pay mechanics to do it for me?
2) My mechanic has never done a swap like this before so I figured I know just as much as he does at this point.
3) I will control the quality of the job.
4) I will learn everything about my Jeep, inside out.
5) I will repair or improve sensitive areas (eg. rust, wiring close to exhaust, etc)
6) I will proudly drive a rig that I built personally.
Being an apartment dweller I could not do this out on the street so I rented a 430 sq. ft garage and bought myself some tools from a couple of retired mechanics. I now have an engine crane, a floor jack, axle stands, a 130A MIG welder, an air compressor and some basic hand tools among other things. I still need some more tools such as a lifting chain or sling for the engine and other stuff but I'll get them as I go along.
Many have told me that the most important part in preparation is correct labeling and storage of everything I pull off. I got myself a couple of rolls of masking tape, some Ziploc bags and permanent markers which should help in the logistics of this project. Let's not forget my fully charged camera as well.
So with the above all said and done, I'm eagerly waiting for your comments and/or suggestions as I plunge into the unknown. I'll start posting pictures tomorrow.
