Plasma cutter is a little coarse for this. I start the cut with an abrasive cutoff wheel and finish with a reciprocating body saw. Nice cut and doesn't put all the cutoff dust in the air.

Finished up the driver's side hood panel. I cut out a square comprising the factory hole where the intake passed through and will use it on the passenger side. I used the hinges and latches from a spare deuce side cover to make this cover open. Not perfect but nothing on the truck is.

I added a "real" boost gauge and post-turbo pyrometer; both Autometer. I used Autometer cups secured with a hose clamp around the steering column. Decent visibility but this puts them in the way of the fuel tank selector switch. I may rotate the entire assembly clockwise to improve visibility...

I, like many others, was curious about any efficiency improvement with the turbo. Obviously, I don't have the means to test this but it is interesting to look at the BSFC curves for the NHC250, NTC290, and LDS465. BSFC is brake specific fuel consumption and the units are horsepower/lbs...

The head has dowel pins on the bottom of the exhaust port gasket face which are used to locate the exhaust manifold on the head. The exhaust manifold has corresponding dowel pin holes. The aftermarket PAI has them on both top and bottom; the AKMI only on one side. This became an issue with...

Thank you all for the comments. I do feel fortunate to have a nice place to work and funding to pursue these hobbies. Really grateful to the wife who supports these endeavors with patience and finances. I am a lot more protective of my hearing as I get older. I took the wife for a drive...

I pie-cut a length of 5" exhaust tubing to create a 20° elbow and mounted the air cleaner. The air cleaner is supported on three points by structure under the fender; I plan on fabricating up something to support the fourth point. And, I need to finish up the side covers and mount the guard on...

Thanks. For this size engine and horsepower, Cummins didn't aftercool (at least to the best of my knowledge). Others who have done this mod have reported lower EGT numbers and have been able to increase the fuel.

I know that the title is a big claim but I really do think that this worked out well. I used of a factory Cummins crossover tube (142248 ) and intake manifold. This particular intake retains the flame heater. While the turbo outlet and crossover inlet don't exactly line up this is easily...

Some White tractors use a variant of the multifuel and the same head gasket. The service manual indicates that a retorque is required.

This is a "Rubber Shifter Boot For Freightliner FLD and Classic models 027076457 284053401" Should be able to find one buy it now for ~$20. I got the trim ring from a separate online truck retailer; can't remember where though. I looked awhile to find one that wasn't insanely priced. I...

Some more pics. The air out to the brake switch etc is also NPT. I am showing a metric banjo bolt that fits the isuzu booster next to the oem banjo bolt. It may be possible to drill out the metric isuzu hole and drill/ tap/ thread insert to fit the oem banjo bolt.

1) The air inlet is a male metric fitting. I found the appropriate flare fitting but lost the bookmark on Aliexpress. It may be possible to weld on a different fitting. 2) The female brake fluid input is metric. I was planning on having a custom banjo bolt fabricated as the original...
