Hey guys, thinking about supercharging my 02 5.4. I found one from a Lightning but wondering what all else i'll need since it is just the super charger. i know i'll need injectors, plugs and a tune but what about Intake mani? and other items? Thanks!!

 

Definitely want to rebuild your motor with forged parts if you plan on running a decent amount of boost

 

I have an extra engine that I'm rebuilding but some one said if I stay around 6-8psi, I wont need forgedparts. But was thinking bout just finding Lightning or Harley parts and putting those in. Given the block is the same. A buddy of mine has a engine out of a Lightning that was totalled that I'm trying to get him to sell me

 

The block and rotating assembly are the same in a regular 5.4 or a lightning/harley. They are not 2 completely different rotating assemblies. I have a wrecked lightning in my brothers back yard i bought at a auction and we pulled motor months ago and tore it apart thinking it was heavier duty, absolutely no difference in the short block. Same crank, rods and pistions.

 

Nope. They are in fact totally different.

If the engine you have doesn't have a different rotating assembly, then you don't have a lighting engine.

"The 5.4L Triton V-8 was already an extremely potent engine, but SVT engineers wanted to take it to the next level. Since the Triton engine block featured a "deep skirt" design giving it great rigidity, it was decided to boost performance with a supercharger. SVT engineers added a forged steel crankshaft, sinter-forged alloy connecting rods, and forged pistons, lowering the compression ratio to 8.4:1 for the addition of the supercharger. The supercharger is a Roots-type Eaton Corporation Generation IV model that sits atop the intake system. Located directly under the supercharger is a water-to-air intercooler to cool the compressed air as it enters the intake."

The lightning engines have weak rods (relatively speaking) but the pistons and crank are good. With stock L internals you would be good to ~600-650bhp depending on your tune and how hard you run it. If you need more power than that, I'd replace the rods. The factory pistons and crank can support well north of 800bhp. If you troll the L forums I'm sure you could pick up some used guts cheaply to start your build.

Send the eaton to Steigmeier for a port job and a snake bite kit, port match the heads and call it a day. With a good tune, headers, mild port job on the Eaton and the heads you'll have enough power to find all the little weak points in your driveline...
