Ok I have a 2000 F250 superduty with a 5.4, thing has no *****. Its lifted on 22's and 37" tires so the lightning swap would be great to give me the torque I need. It has a 220,000 miles on it and its not gonna last much longer. Bad rod nock or something at higher rpm's. I bought another motor though that i'm gonna build to handle the lightning swap. I have read way too many threads, articles or whatever that i'm completely mind ****ed so i'm just gonna start my own thread and hopefully all of you can help me with this.

As for the rebuild, the motor I got is from a 2002 excursion. It has a spun crank bearing so im just gonna get a complete forged rotating assembly. I guess im gonna go .20 over but as for compression i'm kind of lost on what I should do. I want the motor to last. I'm just gonna do all stock lightning stuff for now but later on down the road if I want to get a ported blower, kenne bell, etc.... I want the motor to be able to handle it. The only reasonable rotating assembly I have found is from modmaxracing.com. Does anyone know if modmax is good? I can pick whatever compression setup I want but not sure what would be good. They have 3 different ratio's posted on the 5.4 kit..... 10.82:1, 9.60:1, or 8.89:1. Im thinking the 9.60:1. Who knows though. I need help.

As for the blower setup, i'm still piecing this together but have the main things, complete blower assembly from the heads up, maf and stock airbox and misc things here and there, need little odds and ends. Still need a heat exchanger, probably just get a stock one for now since its gonna be a stock setup. Ive been to the madenterprise site and looked at the list he has so i'm just going off that. I'm sure when it gets down to the actual install that i'll need more. (I know I still need alot... Like alternator, throttle and cruise cable, fuel pump, etc). I'm kind of confused on the whole pulley setup and what exactly I need. I have the upper and lower supercharger pulley but what else is there? Im lost. I know that there are multiple write ups on this swap on a F150 but havent found one on a F250. Shouldnt be much diff but still havent seen an actuall thread on the swap from start to finish, pics etc.

As for the tranny. I guess I mine as well do this too but what should I need? I dont even know what tranny I have, Its a 2000 5.4 automatic with 4x4. I need help with this too. Obviously I want to beef it up to handle the extra power but not sure how to go about it.

I guess I pretty much need help with everything. Maybe someone can point me in the right direction with this. Any help would be greatly appreciated cuz like I said im so confused now after reading everything that I have read for the past 6 months.

Im gonna do this no matter what so I NEED HELP!!! You guys know your shizit!!!! I dont!!

Thanks,
Brent

 

make sure you get 5.4 specific pistons...



basicly everything from the F-150 swap is what you're going to need


hit up "crash" he did the same swap on a superduty a couple years ago and he can provide you some guidance regarding the throttle and cruise control cables




*edit* as far as the tranny just install a valve body for now and consider regearing if you haven't done so already, since those are some tall tires and if you don't regear you're gonna be playing with fire...

 

i will be using modmax when i do my rebuild, the seem to have a good rep from the mustang community.
i also think the 9.60:1 would be perfect for what you need, the 10.89:1 would make more power but with boost i doubt you'd be able to run pump gas.

 

Ok thanks, I need to get ahold of that Crash guy because I was wondering about the throttle and cruise control cables. I did a search but couldnt find the write up on it or anything about a superduty with an eaton.

 

i have a stock heat exchanger if your still needing one and mounting bracket too

 

Yes I need the stock heat exchanger and brackets. Thank you!! How much?

 

80 dollars does that sound fair

 

Sounds good to me. How much you think shipping would be to florida?

 

ill pay shipping

 

pm me

 

Didnt think u could pm on this forum, I dont have the option. It just says I can email you. I'll email.

 

As for the valve body do I just get an upgraded one? One for a lightning or what? I think I have the 4R100 so thats a plus. Thanks!!

 

what gears do you have???


I do not see why a lightning/harley truck valve body wouldn't work

 

Still would put a shift kit in 4r100.

You may already have a forged crank in the motor, check. And yes forged is way to go with rods and pistons. You don't need to go to MODMAX, there are a lot of these parts out there at OK prices. And if your going to run high boost application I would recommend head studs, expecially since all the bolts in the modular motor are torgue to yield and have to be replaced in the rebuild anyway. OBTW these engines are not cheap to rebuild, bolts and gaskets will run you a lot of money.

As far as compression goes, 9.6 is not what you want if you are going with high boost. So for low rpm and low boost maybe you could handle 9.6, but as you go up detonation is probably going to get you. Below 9 is where I think you would want to be if your going to be near 10lbs of boost, so look to the future Kenne Bell/Whipple etc.

So tarajerame what is the diffrence between 4.6 and 5.4 pistons? Most companies sell them as the same.

 

I think you would be wasting your time with an L or Harley valve body!
You should go with a Factory teach valve body. Or a shift kit.



I agree,
you will be better off with the 8.89;1 compression!

My last block was 8.4:1 and it was great. My new block is 9.0;1 and I can only run 8&1/2* of timing on street gas.
The power you pickup with the higher compression,,,you lose with the low timing!
