A Mate of mine has bought a 2.8 Hilux and it is running a Nissan Turbo on it, it is bolted on using a manufactured manifold. Also set up with a front mount intercooler.
I am really curious to know what the turbo is and where the manifold came from.
I will be getting some pictures of it soon, but thought 'd throw up the question and see if anyone had come across this before and had any info.
Cheers.

Hedging my bets it will either be a sr20 Silvia or td27-t

Yea I believe the diesel nissan turbos commonly found are a Hitachi ht12 from the td27, the ht14 from the td42 and the Garrett gt2052 or something for the later qd32
