Since I'm going to be spinning almost double original rpm, gotta fix some things in the engine. First on the list are the supercharger end plates. Originally the rotor shaft just rode in the aluminum bore of the end plate. To help handle the rpms I intend, I picked up some bronze bushing stock and made 4 bushings.

Checked tramming of head and then used a coaxial center indicator to find center of the bore.


First one all done, left it .003" undersize so it can honed to final dimension.

Thanks guys! This build has been years in the making so why skimp on it now?

I have a divorced 203 rangebox and a dodge 205 I'll happily put towards the trade of a divorced 273 from a kodiak/top kick if anyone has one kicking around.


I'm a very widely diversified business. European diesel performance is my original specialty, however I literally get into everything that's made of metal or has an engine. Nothing is safe here :sonicjay:. I'm a machinist/fabricator by initial trade but I'm also a master cert auto/diesel technician. I do lots of oddball custom machine/fab work for vintage cars, hot rods, race cars, off road trucks, and boats. Everything from custom engine/trans builds, manual swaps, cages, headers, turbo setups, standalone efi wiring, and custom chassis work gets covered. It keeps my days interesting :).

Got the blower assembled today in between jobs and started to modify the turbo blower inlet. Need to grab some stainless cap screws for the blower end covers tomorrow in town.



Turbo blowers had bypass valves on one end so the inlet housing is different than a non turbo one. Nothing a small piece of aluminum doesn't make up.

Picked up some stainless bolts for the end covers. Mmmmm....shiny. All powdercoat work was done by QC in sterling heights. They were fantastic guys to deal with.

Not huge news, but I got the crankshaft for the air compressor back from being ground .010" on the rod journals. The compressor housings are done at QC coatings down in detroit, the next time I'm down that way I'll pick them up.



I heat my shop and house with an indoor boiler, so I had to break down and steal some Chevy funds to buy a splitter. I got a 6.5hp Lister diesel for free from a buddy a few years ago and this was the perfect application for it. Fabbed up some frame work, a pulley, and a tank. In theory, time saved splitting will give me more time over the winter to work on fun stuff in a warm shop!

Yup, this totally bad ass! The shop is awesome for sure!
Do you really have to go that far got powder coating?
Thanks!

I don't have to, but that's who I started all the coating with and to keep all the colors matching, I'll finish with them. I travel to detroit once every month or two, so it's not a huge deal. Not like like is a deadline project :sonicjay:.



As life goes, nothing goes to plan. Kids came into the picture which means a regular cab truck doesn't work well anymore and my tdi swapped ranger has become the wheeling toy, so now I need a heavy tow rig that's off road friendly. Since I wanted to stay with a square chevy, I found an 82 crew cab k30 in the cali desert with 110k and a 454/465/205. Truck is in really good shape overall, just baked from california sun. I drove the K30 back this summer and sold the red K10 with the D60/D70 axles and other parts I wouldn't need anymore.



The K30 is still getting the same detroit engine and eaton 10 speed. Will probably run an air shift duece rockwell transfer case as finding a kodiak/top kick divorced 273 for under $1500 is a unicorn hunt. An extra 200lbs in this truck isn't going to matter at all LOL. For suspension, going to do 4 link air in the rear and 3 link air in the front. When I do the rear suspension, I'll push the rear axle back 18-20" and take off the last 10" of frame. It already has the turning radius of a bus, so what's a little more haha.




If anyone wants a california 99% rust free bed and good running 454/465/205 they're for sale!

So you're going with the N3 injectors then?

Make sure you get the actual detroit diesel remans. They are made in Grand Rapids by the airport. The competition cut some serious corners with the other aftermarket remans. :thumb:

I may be biased since I used to work there for my engineering co-op and did R&D on competitors injectors and potential future work for the company while I was there.


Sorry I'm coming in late to this build, somehow it slipped past my radar. I've always wanted to do a build with one of the old two stroke detroits.

Good to know there's another Detroit nut here! I have 2 sets of fresh reliabilt ddec 6v92T injectors to use. They flow about 80-85cc from the documentation Ive found, should be plenty to start with. The other set is at exergy engineering in grand rapids to modify for much higher flow to get my target 400+whp.

Going to try and get the short block built over the next few weeks now that the k30 is mobile again on its own power. Started with rebuilding the carb, then heater core leaked on the test drive and brakes felt funny. So then a rear wheel cylinder was added to the list :sonicjay:. When I drove it from Cali back in August, heater core didnt leak, ran good, and brakes felt great. Sat for 3 months and it falls apart per Murphy's law.

Those were made in gr too.

If you run into trouble getting the injectors bumped i could try to reach out to some old colleagues. Not sure how busy they’ve been, but they did the injectors for the pikes peak semi racer guys before while i was there.

I'll give you a shout if exergy doesn't come through for sure man!



Some buddies showed up last night, some beers were opened, that led to the shop getting reorganized, which led to the detroit getting pulled out and worked on :sonicjay:.

Crank plastigauged right at .002" and spins like a dream.




Need to get make a trip for stainless bolts for the front cover, oil cooler, and air compressor brackets. Slowly but surely!
