Hello, long time lurker here.

I'm building my dad an F250 with a cummins engine swap so he's giving me his 99 ecsb with 4.8L/4l60e since he has no room for it. I happen to have a practicly new procharger D1SC sitting in my shop at the house from another project since I have no use for it I want to either sell it or use it. I'm used to driving my 524hp duramax powered truck everyday and that little 4.8L is anemic so can I use the D1SC on it? I know I'd have to source brackets, crank pulley, injectors and put a tune on it which is no problem since I make my own tunes with efilive. (anyone know what engine computer the 99 4.8 uses?)

Thanks guys
Randy

 

I say go for it. You'll need a pump/injector upgrade, custom tune and be good to go. Don't expect diesel like torque though.

 

Fuel, running gear upgrades, let it eat..

 

And a new tranny when the stock 4L60 takes a . Mine lasted less than a week after I put the P-1 on, but it was a ECSB.

 

I'm no expert, but woudnt it be hard to keep the boost low with a D1SC on a 4.8? I seem to remember reading a guy with a 5.3 on here having to run a very large pully just to keep the boost at a moderate safe level, and I think it was still upwards of 10psi. I could be mistaken though. Either way, if it is free I would use it.

 

That's the whole deal the truck is free and I have the procharger laying around lol. The tranny is almost new (sadly just stock and 60's are weak in my opinion). I can pick up a t56 pretty easy but after many hours of searching I can't find any definitive answer saying it will bolt up to my early 2000 4.8. Some say the crank is too long and the tranny needs a spacer between the tranny and bellhousing others say it works fine. Worse case scenario for menus blowing the engine and tranny and I just drop in a duramax or stroked 6.0 and a beefed up tranny or the t56 and get serious about it.

I'd enjoy anyone's comments on it. Guess I should post my plan in the general section.

By the way I appreciate the help guys, I'm surprised I didn't get the standard forum response of " that'll never work", "you'll blow it up", "don't do it", etc.

 

If you are going to boost it I would just plan on building an 80E. Then build up a 6 liter while you are running the 4.8.

 

Like others have said, you'll need a fuel pump and injector upgrades, maybe some running gear upgrades.

 

Talked to rockland standard gear about a T56, AWD transfer case and their adapter(have to order one for my 67 F100 AWD anyway). I've built enough chassis to know it wouldnt be that hard for me to swap the front frame of an SS. I'd imagine you could fit coilover shocks up front and ditch the torsion bars (I've done this on a 2500HD 4wd already, worked great) to help lower it while your at it. That could be a healthy setup. Run the 4.8L with the 60e till it blows then drop in 6.0L/t56?

 

D1sc on a stock 5.3 with cat-back will make about 12-14psi with a 4.00" pulley. Well within the range of an experienced tuner. They make pulleys as large as 4.5". Suffice to say belt slip wouldn't be a problem.
