Pics of my 7.3 IDI Buildup...

@Darrin... I was being tongue in cheek as well. Thanks for the complements!

I agree about the hole in the hood. It'd be nice, but don't want it exposed to the elements. I work near the sea, so I want as little saltwater as possible going under there.

Yes, paint is in the works too. I already have it. Some high dollar DuPont International Harvester Red Hi-Gloss with clear coat.

That is beautiful!

I just wish my engine was as clean as yours.

Do the C ring headgaskets require special machining? Or will the work in a stock type situation?

i cnt wait to see how this baby sounds gotta do a vid of the start up

Probably going to sound like a 747 taxiing down the highway though.

Absolutely nothing wrong with that!

I'm pretty sure Heath told me that the C ring does have to be machined into the block, but I'd say they are well worth doing to hold the boost.

I just want to hear an IDI spinning 5000 rpm, as long as it is not mine.

C-rings do have to be machined into the deck of the block. The machine shop had to make a tool just for this. It was done on the boring machine after finish honing each cylinder, that way the groove was perfectly centered around the bore. The Hypermax folks told me this is the same setup used on the famed 900hp compound turbo IDI back in the day. Held 150 psi of boost with no issues.

There will definitely be video taken of the first start. That is for SURE!

What kind of time frame are we looking at?

 

[Matrix37495]

I'm sure that regular headgaskets will hold all the boost i'll ever give it, i was just curious...

Do you have any pics of the head gaskets? I'm curious what the "c-ring" part looks like.

 

[86truckpull]

How far away from first start up do you think you are

Hey I saw NMB2's build on another site, most of his pistons were cracked. I'm not quite sure why they were fractured but do you think it was from heat or boost pressure or something else? He said he is going to coat the pistons this time and thinks it will prevent it in the future.

Update on his piston fractures is that he was holding it at 1200* for 5 to 10 mins at a time going uphill and would hit 1400* also. So that definitely explains the fractures. But overall, the pistons didn't look as bad as one would think though.

Do you plan on adding an ethier system to get it started sinc you are dropping the compression so low?
