I am building a 1900 for pulling and am planning on turboing the big detroit. We are thinking of putting N kit pistons and sleeves (21:1 compression) and would like to know how big of a turbo we can safely run without blowing it up. I've heard of people putting drains in the airbox to exhaust boost pressure when not pulling. what is involved in this? Thanks for any help.

Hey Josh, one thing I do know is the "T" engine is very different, block rods and pistons are very different, the pistons are two piece and the rods BOLT up to the wrist pins, the rod and main bearings are larger, but I can not tell you how long the NA engine would last turboed.
If it were me if all I had was an NA engine I"d put realy big injectors in it and worry about putting all that power to the ground, don"t let people fool you, a diesel engine makes more power long after the point it starts to smoke, granted the fuel efficiency goes to hell but who cares, and all that smoke is really cool!!
My two cents worth anyway

After these idiots stop picking on you, see if you can use this. A Detroit engineer I talked to says for road purposes you can safely run 28 pounds of boost. I saw a guy some years back that pulled Modified 7000# and 9000# with a 8V92 with two turbos and he was turning 5500 RPM and that never let loose in four years of pulling. I don't think any Cummins could do that.

I'M NOT EVEN SURE ANY OF THESE GUYS KNOW WHAT A DETRIOT IS BUT i RUNS ABOUT 50 OF THEM ON THE RD A DAY FOR 1000S OF MILES ANSWER TO YOU QUESTION IS YOU CAN'T OVER CHARGE IT THE 2 CYCLES THAT IS BECAUSE THE BLOWER RESTICTS THE FLOW WON'T LET IT HAPPEN THATS A DOWNFALL WITH THEM FOR YRS WEVE WORKED WITH DETRIOT WITH DIFFRENT TYPES OF BYPASSES WITH TURBO GOING AROUND BLOWER TTHE BLOWER IS GEAR DRIVEN AND WONT LET PUT TOO MUCH PRESURE AND IF YOU WORRIED ABOUT IT PUT A WASTE DUMP ON IT

Im a big detroit fan i dont care what these cummins guys say how loud they are that keeps your blood prressure down when ur workig late keeps you away from the caffine. but any way i have a detroit binder it has the specs on the all detroit engines on my spec sheet hear the 4-53T has 18.7to 1 compression with N65 injectors and puts out 175 BHP, with 420 LBS of Torque it doesnt say what size of turbo it has but. my dad has work on 2 cycle detroti for 30 years hes just told my the detroit dealer will give you different sleeves when you order your turbo.. you'l basicly blow the head off if you dont lower your compression ratio.

I know a guy who worked for detroit and he says the high compression is ok for short runs like in tractor pulling. the 21 to 1 ratio is meant for non turboed motors. thanks for the help

after your done with all the mods and gadgets on it, don't forget to remove all the Oliver stickers off of this "whatever you call it" pulling thing.

A Detriot diesel is the only engine that can turn diesel fuel into nothing but noise

josh, don't listen to all the "know it all's that responded, friend of mine pulled a 1950 with a turbo, pulled road gear in 9000 lb class against all the "big bad red things", that little 4 cylinder was pretty impressive, email me, i'll tell you about the turbo, fuel, etc.
