My goal is to make as many detailed notes I can about my swap, so if you want to run a simialar 5.3, 4l60e setup in a TJ super simple on details and save you some $$ on wiring.
Decided to start this thread separate from my build thread, to go indepth into what I'm doing on my 5.3 swap, which might help someone down the road.
Current jeep 97 TJ ,4.0, Auto, worn out engine
-Donor bought complete 02 4x4 Tahoe and drove it home-parting out leftovers
-Using Alldatadiy for my wiring info and online searches-
-I plan to use my stock TJ computer to run my factory gauges- all except aftermarket dash mounted tach
-Plan to use my stock 231 with SYE, modded using S10 tcase parts, advanced adapters vss signal between tranny-tcase on factory adapter.
-Novak weld in mounts,
-Novak transfercase shifter
I plan to be as detailed as possible to maybe help the next guy.
Update finally home for weekend so I can do some work on the Jeep. I got frontend all pulled off , tcase removed and all i have left is engine mounts and fuel line then we will lift the engine and tranny out. Doing everything at my brothers shop. Tommorow I have to put all the TTB and build custom longarms back under my explorer sport tuff truck so I can sell it for funds for this. Drove the Tahoe around some more I have out prolly 200 miles on it.
I also plan to redo my brakes and not reinstall the abs unit for those who noticed it gone. For now just the nitty gritty removing and labeling stuff.
I'm getting closer. Tahoe is all apart, sold quite a bit of stuff, which is bringing the cost of engine and tranny down to a really good deal as planned and funding swap parts.
Went ahead and ordered Novak Ceramic coated conversion headers and elbows for intake
From advanced ordered VSS to go in back side of transmission and also ordered Lokar shifter
I removed harness from 5.3 last night and will be starting to condense it down based on LS1 tech site info, I will be making my own littler fuse box and relay and tieing into jeep in areas, more details once I get there.
Hoping to really make some progress this weekend.
Been thinking about a conversion radiator US made from guy on Ebay named Disrad, anyone have any experience with him, I read really good reviews from others on his products.
This is my info requested to person tuning my Computer:
I bought a donor vehicle so all parts, engine 5.3/tranny 4l60e & computer are all from 2002 Chevy Tahoe.
I will be installing these into my 97 Jeep TJ off-road Jeep, using the 5.3 and 4l60e from Tahoe, I will be using my own transfer case and putting a VSS sensor from Advanced Adapter in backside of transmission that says 40 Pulse GM.
My thoughts on programming, correct me if I’m wrong. This is my 1st Chevy engine project ever switched over from Ford
Disable rear oxygen sensors
Disable Evap canister Purge
Disable E85 functions
-Mine did not have EGR
Not sure what AIR injection is-but prolly want it disabled also if not needed –don’t think it has this either
Remove computer controlled A/C, I do plan to run my ac maybe sometime, but my understanding is I can wire it up from the original jeep wiring.
Use programming based on a 2wd 5.3-4l60e setup, since I’m running VSS in between transmission & t-case
I did not have a factory electric fan, but I plan on running one. I want fan relay wire to turn on for 195 degree, I installed pin on #42 for fan Blue con
Pin #33 -Needs programmed to accept single wire park/neutral signal Blue Connector
Pin # 71 –Needs programmed for Tow Haul Mode switch input -Blue connector –I added pin
Running 35in tires
Tach- I plan to run an aftermarket tach and have 680 Ohm ¼ watt resistor on way, so whatever needs for that and I will put it on the 4cyl setting.
I plan to use my stock Jeep dash cluster, my understanding is the GM PCM puts out a signal for speedometer, but it is likely not the same signal. Can this output be changed to match what the Jeep needs; I will be feeding the input back into my Jeep Pcm that will remain in the Jeep to run the gauges from what I understand. My understanding from online reading is the Jeep PCM reads a 8000 PPM square wave signal for the speedometer- hopefully that is correct and can the out put from pcm be changed to do that.
-Engine will be all stock, using Novak block hugger shorty headers
