5.4l engine swap for lightning
Some of you know that my wife killed her truck several months ago. It has been sitting in the driveway waiting to be saved ever since. I may have found a complete lightning engine, supercharger, computer, wiring harness, and transmission from the same year(2002) as my wifes truck.
My questions are, will the lightning engine work with my current manual transmission, and is there any other reason why this swap wont work?
My thinking is that if i am replacing the engine anyway, i may as well get the most out of it.
Thanks

did you ever figure out the final issue with the motor. it might be something like a spun bearing. and is the lightning drivetrain for free or how much? it might be more for your liking to spring for a complete rebuild of the original motor and do a few performance upgrades. you could easily with just like 2 grand get way more out of the 5.4 than the Lightning 5.4.

for the price i can get everything from the lightning , and the sale of the lightning transmission, and the current parts that will be replaced i will be spending less then what it will cost to do a rebuild.

ok. see i didnt know if you was having to spend a ton or not. and as far as the manual tranny working with the L i think it will. im pretty sure it will. maybe someone else with more experience on these new trucks could come along and assure the answer.

Well, i have no idea why i typed manual...her truck has an automatic transmission.(stupid mistake) My main concern is the extra power eating the AUTOMATIC transmission. I would think that everything else would be pretty straight forward...

If you have the 4R100 it will be fine, the 4R70 will have a drastically reduced life behind that engine. You'll also need the L fuel pump BTW.

The 4r70w will hold up just fine, there are quite a few people on this site that supercharged there trucks and dont have any issues, but sometimes trannys go, but i dont think its to often. And how you drive makes a huge difference. If your constantly abusing it, of course its going to go early.

i thought there was a kit that some site was selling with all the required components for a lightning swap (other than the motor, trans, ecm) like all the pullies, brackets, etc. and that kit alone was like $1800. ill try to find where i was reading about it.

One problem is that the 4r70w will be incompatible with the Lightning ECM, the lightning only came with the 4r100, and the two tranmissions, wont work with each others ecms, due to different hardware to control them.
So you will have to have the transmission out of the lightning if you use the ecm that goes with it.
