I'm a little past due... but its update time!

Originally planned to be running last Wednesday night, it got bumped back to running on Friday night at about 11pm. Really runs great and I can't complain so far but there's only about 100 miles on it yet. The only change from the build listed earlier is that I decided to do a minor port/polish to the heads(not a first, but for a 7.3 yes) since they were going to be getting some machining for re-surfacing and cleaned up after that anyway. I don't remember this thing moving the speedo for sub-30 lbs boost as fast as it does now.

Found several things that left me scratching my head a little. Threads on the oil pressure sender on the reservoir were nearly completely stripped out... not sure how that sender stayed put. Couple piston pin circlips were 'sideways,' although I'm not sure the RPMs would ever be high enough to bother that. The dipstick holder in the pan, even though I replaced the o-ring while the engine was still in the truck earlier and it sealed well, I found that the o-ring was infact not entirely seated properly.

All in all seemed like a success. I'm really glad I have the know-how and resources to accomplish a task like this myself(with help pulling and dropping the engine back on the mounts.

Awesome!

May I asked why you switched turbos?

Sure Dave, few reasons I went down in turbo size was that I did miss the quicker spool up of a smaller turbo. I didn't get a lot of 'tune-time' with the 76mm turbo and I probably could have helped that, but even with a well controlled skinny pedal it really needed some RPMs to spool decent. Another reason is the local truck/tractor pull organization is 2.8 limit for street diesels. Not sure I'll be doing it but it's an itch I'd like to scratch, lol, and if I did I'd like to be legal for prizes(ok, maybe that's high expectations)

Here's a video of a no-very low boost 20mph roll on throttle with VERY little smoke and I never pushed past 30psi boost. Of the short clip on the speedo, I think 50-65 is the fastest.

Here's a side by side of the turbine housings, sledgehammer to stock H2E on the right.

I've never been so scared to hear an intercooler boot blow off in my life....


and then only a few moments later so relieved. Killed the engine even, walked around, saw some dripping, THANKFULLY just the A/C.

Must not have been quite snug enough. I've been keeping boost pretty much sub-30 lbs, as hard as it is knowing there is more on tap.

Slightly braver now... another acceleration run, not breaking 40 PSI boost this time. More is on tap... just need to finish up the 03 rebuild before I get braver(or stupider) yet. lol
