Wish I had done it right the first time........
I started my build with a 97 TJ, 4cyl, ax5. I blew the 4cyl and was hell bent on doing a 4.3 chevy vortec swap!! I started off with a junk yard motor....*** deep in the build that motor siezed up, and the transmission I had, a 700r4 was left at a friends shop where I had welded in the motor mount that ended up dissappearing. There went $400.
I bought another 4.3, 4L60e($500) and began the swap again. I went with Howell EFI custom wiring harnes($550), and getting my computer flashed and reprogrammed by LT1swap.com($75). After getting this motor mounted I realized my stock TJ radiator wasnt going to work. I bought a Champion racing 3 core radiator($225) to keep things cool. I got this motor running, but it was running ruff. I replaced the spider injection system($190) this helped but didnt cure my problem. I went with a inline high pressure holley fuel pump($275). Motor was running but now running hot.....blown head gaskets($60 gasket kit, $150 to get the heads checked and planed, $40 head studs). I was able to get it all put back together and take the jeep out for its maiden run. I got to wheel a whole entire hour before I spun 3 of the 4 main bearings!!!
So, bought a running in the vehical motor for $600 at a local yard. I brought it home and installed it with in the weekend, while making all my final once overs under the hood, I smelled that awful white bluish smoke. The motor had over heated. I did another head gasket job($60 gaskets, $150 head work, $40 new studs). This didnt fix all my problems with this motor, I know had a ring or two stuck so the jeep continuislly smoked. Time to do things right, I broke down and bought a full rebuild kit from summit racing($509).
I took the motor to a local guy that builds street rods and classic cars, he charged me $250 to rebuild it since i had taken the motor out for him.
I got the rebuilt motor back and was hooking everything up and noticed the high pressure fuel line had a kink in it from being taken on and off so many times. I went to my local NAPA store and had them build me a custom high pressure hose($100), worked flawlessly! Since I was thinking the motor is now new, she needs new water pump($60), a new power steering pump($158), and finally a new alternator($70).
So, lesson learned was that when doing a project one needs to fully research what it all entails including the cost. You might think a junk yard motor is great because you got a steal of a price, but it is way easier to rebuild it before going thru all the trouble installing it and tearing it down multiple times. I love working on my jeep, but I should have been enjoing it instead of it sitting for nearly two years.
