Carl M Posted February 4, 2018 Share Posted February 4, 2018 I have a 1960 B42 and I'm getting a 673 naturally aspirated, is it possible to add a turbo? Since it rolled off the assembly line 18 years before I was born I'm a newbie. Any advice is appreciated.

Maddog13407 Posted February 5, 2018 Share Posted February 5, 2018 and if your starting with a B42 and wanna install a 673 you better have a Diesel parts truck for radiator, motor mounts, transmission and rear hogs head and the clutch shaft that goes thru the spring hanger is different, the keyways are in different spots 1 Quote Link to comment https://www.bigmacktrucks.com/topic/52415-673-na-covert-to-turbo/#findComment-391312 Share on other sites More sharing options...

mattb73lt Posted February 6, 2018 Share Posted February 6, 2018 That's what I did when I swapped over my B-42 to diesel. I was able to get a B-61SX from behind the cab forward, it had everything but the motor. Everything bolted right in, front cross member, transmission mounts, etc. There's a lot that you'll need that you'll have to scrounge for to get it done right (Shutters, brackets, air lines). The good thing is, the frame is predrilled for both mounts(Gas and Diesel). It was actually a very easy swap to bolt right in. I started off with a 1957 END-673 for ten years and after having a major issue with it a 1973 ENDT-675 (237) since 2011. Miss the bark of the 673, but love the power of the 237.

Freightrain Posted February 6, 2018 Share Posted February 6, 2018 Ditto on all the above. If you don't plan on pulling much weight, just leave it NA. I spent 14 yrs wanting to do the same thing to my 673. I just bought a 237 and got some real power. Quote Larry 1959 B61 Liv'n Large......................

davehummell Posted February 8, 2018 Share Posted February 8, 2018 wouldn't the compression be a little high on that engine to turbo it? Quote Link to comment https://www.bigmacktrucks.com/topic/52415-673-na-covert-to-turbo/#findComment-391467 Share on other sites More sharing options...
