You don't need to be able to build them yourself, you were still the right guy for the job. You got the right info on the P400 to the right people (Moroso), to have the right pan made for those of us who have, or would like to see a P400 in our trucks someday. Especially if we're driving a 4WD.I don't have the time or welding skills to do one that nice. I miss the smiles to! I did a whole Chrismas story last year using nothing but smilies

First thing, sorry for calling you "Joey" Jody. Yes would be a good canidate for powdercoat. For sure post a picture if you do that!
That's OK, just don't call me late for supper or cold beer!
I made a video of removing the heads, but it did not come out very well. Kind of dark and it cut off and I did not know it so some of the info wasint recorded. If anyone want to see it anyway I'll post it up.

Even a bad video is better than no video at all. I wanna see it.

Leroy, how much oil capacity will you be running with this setup?
I've been anxious to see this project take off with the banks manifold and custom crossover pipe.
Good luck.

I had looked into the banks manifold long ago and was advised it was no better then stock in performance. The reason being is the exhaust from the R bank is hitting the wall. The gases have to make a 90 degree turn plus the ports don't look to flow well. With that said the factory 6.5 manifold is not a well flowing piece ether. You can make a shorter crossover for the factory manifolds by taking out the L 90 and using 45's. If flow and performance is the goal, a custom SS turbo header is what is needed. I would be concerned about the heat from the crossover heating up the oil pan raising oil temps with the front crossover. Going down the road all that heat is blowing on the pan. I am not trying to put anyone down this is just what I have experienced. I hope it works out for you and performs well. One more thing is a n/a motor is never more fuel efficient then a turbo motor. The reason a turbo motor gets less mpg is the fuel rate is turned up. Take a stock 6.2 put a turbo on it and leave the fuel alone and you will pick up mileage and a little power even with no extra fuel. The reason is the fuel burns better with the forced air. With a 6.2 n/a it is gutless towing on hills and and all around it will do it but it is struggling. When you are towing and trying to get it moving your pushing more fuel in the motor then is burning. Add a turbo and that fuel will burn with the extra air being forced into the chambers so less pedal is needed to get moving or while towing. Now it is not going to be super powerful with no extra fuel from the pump just more efficient. I hope I have not offended anyone with this.
Did you actually try the Banks? Was it old design or new?
Without going to a custom header (=$$$) the Banks is probably as good as it gets. Just by looking at the manifold it has to be better, for one ALL the exhaust from driver side flows directly into turbo. Exhaust from driver side does not interupt any of the cylinders of passenger side manifold.
Any heat coming off the crossover atleast enough to heat the engine oil is pretty much non existant IMO a simple heat shield would deflect most heat. Crossover will be wraped also.
Being able to swap from turbo to n/a in itself is not more effiecient thats where the multi tune comes in. Flip the tune accordingly. My goal is 25 MPG! Crazy?
I'm thinking at first I'll use a db2 4911 pump though to keep things simple then switch to DS4 later.

I would think that at the very least flow would be much more even, and uniform with the Banks manifold. It is strange the way the factory brought all of the left banks exhaust across the back two cylinders on the right side. About the only decent flowing ones are the front two on the right side. Whether or not the Banks will make more power, I don't know, but the exhaust routing just makes more sense in my head. At least with the Banks manifold, each cylinder gets a more equal flow, rather than having some that are far better, or far worse, than the other cylinders.

The new design is very simular to the stock 6.5 manifold. I think GM copied it or atleast knew about it.
The old design is what I have.
Friggin YouTube videos take way to long to load.

Thanks Leroy, and I'm already looking forward to the next one.

Hey Leroy, What kind are the precups since those fancy heads are already off?

I has boost, :O)
OK finally an update and small progress.
The Optimizer block I built was sold and I got a P400 to replace it with
Just got it on Monday. I had them shipp it to me with the heads loose because I'm going to tear it down to put gapless
rings in it. It was weird that they would not leave the oil pan loose though?
Once I get the engine done I'll be making quick progress on the project.
Wow, that is one sexy engine. I would love one, like all of us, just not sure if I got one, I could run waste fuels with it, lol.
Not sure why you can't run the stock P400 pan in motorhome? The reason we can't run them in most vehicles is the crossmember or diff is in the way. The older square body trucks and motorhomes like yours have nothing in the way.
That is one dare I say it again, sexy oil pan, awesome workmanship.
The Banks lets you keep the A/C without serious mods and bs on the fuel economy. Many, including me, have picked up MPG.
Your crazy,
Its called packaging, and making a turbo system fit without modifying the heater case, frame, transmission, oil pan etc.

Cool thanks. I was just wondering if they came up with anything else or if that was still their premier choice.

For some reason people are not understanding me I guess. I had said a TURBO engine will get better mpg then a N/A engine. Now that can go down hill real fast if you keep your foot in it due to most turbo engine having fuel turned up.
Jody, thank you for the pics. That looks like a very nice pan. I've always had good luck with Moroso pans. The real thing was always far better than any of our homemade imitations.
Leroy, thank you for the honest reminder of the reship cost. That cost wasn't close to being on my radar screen. Who better to buy the parts from than you? You've saved my bacon in the past. Your new website is great.
Keep the videos coming Leroy. Even if I don't get there myself, I'm getting a vicarious thrill out of your build. My two 14 year old sons now recognize your voice and just roll their eyes over dad watching more late night diesel porn on the internet. Can't wait for the next installment.
