What work needs to be done to turbo a 1hz?

437K klms is starting to get up there.....
do a search, you will find a lot of controversy surrounding turbocharging the 1HZ. lots have done it and said it is fine, lots have done it and said it goes bang................
With the amount of klms you have on your truck, I would seriously consider a reco or at the least a freshen up (rings, bearings, head, injectors and pump) before bolting a turbo on......

A standard 1HZ should cope with a turbo if your running less than 12 psi unless its on its last legs, I Have fitted a fair few to customers trucks with good results.
at 400,000kms you really need to know what sort of nick the motor is in, if its had the pump or injectors done already ect, but if it is running well ie. no excsive black or blue smoke, fuming thru the pcv, using oil ect you should be pritty right
You will need to re-tune the injector pump to increse the fuel flow ( Not to hard a job if your capable of fitting the turbo ) If you fit a Pyro gauge to it at the same time under load it should get to 550-600, if its peaking over that you will loose reliability
My comp truck runs a stock 1HZ engine and is happy running at 20psi boost with a top mount intercooler and lots of fuel peaking at 900 on the pyro, but be warned the higher boost and the higher on the pyro you go, you will make more power but the more chance of things going ka-boom increase a stuipid amount

You need to look at all engine tune basics as well. Valve clearances, injectors pump timing to get the best out of it. A pyro is a worthwhile investment.
Does it use oil? Remember that if something is starting to fatigue or fail, turbocharging will only move that forward quicker, you may be in for a world of pain.
"but be warned the higher boost and the higher on the pyro you go, you will make more power"
This statement is not correct, more air into a diesel reduces egt's but only makes slightly more power, its the fuel delivery that changes everything. Both power and egt's.

Ball bearing turbo upgrades for factory turbo vehicles. Got a diesel question just ask.
