I am keeping my other 7.3 that's coming out of the crew cab for this exact reason. So I can fab turbo systems for people. It's not going to be cheap, but I see no reason why I cannot be competitive with other new kits (I am going to guess cheaper), and by far out perform them.

Can't wait for the "J2" line of parts! Good to see the fues system got there!

I have spoken to a lot of trans shops over the years since I owned my first ZF5, and basically what they have told me is that the fact of the matter is you get these "internet experts" that think the ZF5 is weak because of the aluminum case or because the synchro's burnt up, and occasionally the input bearing gets burnt up. Nearly all of those issues are attributed to poor maintenance.
Fact of the matter is, a ZF5 is a superior towing transmission due to the gear ratios, and dwarfs the T18/T19/NP435 in size contest. The main killers of the ZF5 are as follows:
Overheating or synchro failure due to low or burnt oil. People don't change their fluids. ZF put coolers on the ZF6's, I intend to put a cooler on my ZF5 using a transfer pump and bar/plate style cooler with fan.
Secondly, the DMF very often wastes the ZF trans. It needs a nice SMF mated to it. As for the aluminum case being a weak point, that is laughable. Nearly all modern medium/heavy duty trans are alum case.

It all looks good and thanks 
when you get it all back together and you get it all broke in we will have to see your dyno numbers and I'm betting I will be sending you a private message talking more about a kit

Justins grind likely will not work in an engine that doesnrt have cut pistons.
There isnt much room for extra lift .
I will have to mock up my spare engine and clay one sometime.

A cam is a great upgrade on these for more torque, hence the cam that I have been able to supply.

Ken @ Delta said this cam will clear a stock CR engine, but it is the biggest possible cam that will.

RacinNdrummin's engine has the same cam in it, with stock turbo pistons. He converted two lifters to solids and has rotated his engine over, has no valve clash so far... so fingers crossed.
