I bought it from Pat who said it was a new 66 SS. Sweet!

But then as I was playing around with it... I saw this:

turbotag.jpg


Now... Im no dummy but MOD for Model.... HT High Tech SS Stainless Steel 71 71mm?

I know they make them in 66 and 71, so it only makes sense.... right? :confused:
My turbo says the same thing on the tag, but it's a 66. This is what my compressor inducer looks like. Notice how little material there is around the inducer of the compressor wheel in the housing. You can't just machine out the material for the 71 mm wheel. In order to fit the 71 mm wheel the three slots have to be welded up, and then the inducer bore is machined to 71 mm. Then to get the outside of the inducer is drilled to recreate the 3 slots. If you have a 71, you will have a bunch of small holes rather than 3 long slots. Here are my pics.

OK... so I think the motor is ready to go in. I just want to get it bolted into the frame and that will be a major mental hurdle for me. Anything else I need to think of as it goes in? Any special harness routing that needs to be in before the motor sets in or anything like that?

OK trucks out, preparing things. Should I put the injector harness on before it goes in? Seems like it would probably be easier.

What about bracketry on the rear of the motor? Im trying to get the motor sooner than later and plan to attach as much as I can once its in the truck. Are there any brackets IE GPCM or something I need to install to the rear of the engine? I circles some empty holes in red.

What goes into this port by the oil filter?

Yah put as much as you can on, in the last pic by the oil cooler goes a tube that originally went to the egr cooler you should have it somewhere

What if Im not using the EGR cooler or any of that crap? Do I need a block off plate for that lower portion or just put the hose in and cap it or what?

Put the tube/hose back in and buy that "U" hose i gave you the part number for so that is connects to the hose coming through the firewall.

Ah hah perfect I already bought the hose... awesome.

OK me and my buddy are going to lunch but have made some good progress... most of the fuel lines are on and injector harness etc.

I need to find the 4 studs for my tstat housing.... theyre missing.

I found the 2 coolant y gaskets I needed, but I need the large o ring for the black coolant tube that goes down from below the tstat housing.

I need to mount up the injector return harness on the pass side, I know there is a bracket to do it but I cant figure out how it goes.... anyone have a pic of this area?

Also have this bracket that says pass lower side... I know it goes vertical... where and whats it hold?
