Turbo + cheap + 1HZ spells meltdown.
Do some reading in the Diesel Tech section of the forum. There's some great threads on turbo options.
A turbo can totally wake up the 1HZ, but do it cheaply or poorly, you can kill it fast.
Mambatek or Kinugawa do some decent asian made turbos ( thailand or Taiwan i think). But choose wisely.
Low boost and lots of fuel for more power in a 1HZ is a recipe for a cracked head, or cracked pistons.
More boost is a healthier option. 14-18psi.
10 psi is just enough to make some more power, but get you in trouble.
More boost keeps combustion temperatures lower, and its boost that allows an inefficient 1HZ to make better use of the fuel its already burning.
More fuel with low boost raises combustion temperatures which can be a death sentence to a 1HZ.
A boost gauge, and an EGT gauge, and an understanding of why these are relevant is essential to keeping a 1HZ turbo alive.
Learning when to back off, and drop a gear to keep EGTs under control is also essential.
Mambatek turbo, new 1HD-T exhaust manifold ( front part only), Mamba 3" exhaust and gauges would be about as cheap you could do it.
Or, find a good, used 1HD-FTE turbo from a 100series diesel, and buy a 1hd-t manifold.
These turbos come up for sake on Facebook marketplace from guys who have upgraded to aftermarket turbos.
