Opinions and suggestions needed regarding E99 to L99 swap.
First off, hello everyone. I've been a long time fan but have never registered or posted anything until now. Second, I'm sorry for posting about a subject that has probably been beaten to death over the years, but I thank everyone for your help with regards to my dilemma.
I have been reading through a lot of posts regarding E99 to L99 conversions, but am not sure what path to take. I have an E99 7.3 truck that needs a motor (number 7 piston is hurt). Well I happened upon a 2000 7.3 truck basically for free. I bought the truck and sold the zf6, transfer case, and wheels and tires for what I paid for the whole truck. What I'm trying to figure out/ decide is whether to drop in the entire Late 7.3 in place of the Early.
Here are my options as I see it...
Swap just the long blocks or swap the complete motors, turbo, hpop, everything... however for me this is where it gets confusing. What can I swap or Not swap to make it all work as it should? If I swap just the long blocks I still plan on doing a few preventative items such as injector cups, pilot bushing, gaskets, stuff like that (what else would you all recommend?) I believe the up pipes were leaking but cannot afford to upgrade them so I will have to just replace the gaskets.
I also believe that either route I go with will require a turbo rebuild. What is the best option with regards to this? I'm not looking to make a bunch of power and I am on a tight budget.
Next part is, if I do the full swap it will be the complete motor from the turbo on down. I will even be using the computer from from the 2000. First question is, what do I do with the intake heater and supporting wiring? Do I just delete it and remove whatever wires go to it from as far back into the harness as I can trace? Will it cause a check engine light? I believe I had read somewhere that it did, but may be wrong?
Next is, what will need to be done as far as the exhaust? I assume the down pipe will need to be changed as well? The up pipes on the 2000 were for sure leaking, so I will need to reseal those. What about making my own bellowed pipes? Would that solve anything or would the factory connections still be prone to blowing out?
As far as the turbos go, is it cheaper to rebuild or replace? Say for example I have zero knowledge rebuilding a turbo. I would be looking at getting a complete center section rather than tearing apart and replacing seals and bearings and such. Or is it better to buy a whole turbo?
Is doing the E99 to Late conversion worth doing at all? Keep in mind I'm not looking for crazy power. I was daily driving the truck and occasionally would tow a 30' enclosed trailer with my race car and some tools. That's about it. MPG could use improvement and I had read that the newer computer swap would help that out.
I'm sorry if I'm rambling, I've had a lot of things going though my head with regards to this for a few weeks now. I tend to over think things then get stressed out about it LOL. That is the entire reason I'm even posting rather than spending the next several weeks reading through forums to try to come up with a decision on my own.
Bottom line, I need help. I am not very knowledgeable when it comes to Powerstokes. I have mechanical knowledge but its mostly with old school muscle cars.
Any help you guys can give will be very much appreciated! Thanks in advance!
