1hz turbo conversion


Recommended Posts

Any of youse knowledgeable about bolting a turbo onto a diesel NA 80 series land cruiser?

My sis has a majestic shitbox nearing 500,000k and it runs sweet as a nut, manual as well.

We had a talk about boosting it to 1hdt spec using factory stuff but I am not sure how well it would take it or of there were significant differences between the NA and turbo versions.

Whatcha got for me?

5psi will still at least give it a little gain, so if you can get a cheap enough kit ya may as well. Dunno what the fuel limit on these engines are though so you'll likely still have to.be conservative with the smoke screw.

Not like a dirty old 3L that'll take 30psi and a maxed out fuel pump and love it.

This is the same shit,   just minus a cylinder.     50% more power on  8psi boost, with a wind on the pump.  no intercooler,  stock airbox.  just adapter r to stock manifold  and some pipes. 1hz looks to be the same deal

After half a mill the injector springs and fuel pump will be pretty well flogged if they haven't had a rebuild, that alone will make a world of difference.

A turbo will mask all that beautifully

4xoverland on YouTube has a bit on turbo a 1hz.  A few dos and a lot of don’ts... run light psi and get and EGT gauge.  Thin crowns easy to pop and overheat if not careful.  Result was general improvement open road driving 

i breifly considered turboing my one, but by the time one acquires bits and matches it up, tunes etc, be easier to find a 1HD-T, and sell mine underground
