td27 turbo upgrade
Posted: Tue Sep 15, 2015 8:08 pm
hi guys ive seen on here before that there is a model of garrett turbo that can handle 20+ pound that bolts onto a td27 but i cant find the post anywhere does anyone know? cheers
Its the turbo from r50 terranos or R20 intercooled mistrals. Supposedly ball bearing and much stonger than the hitachi turbo on the WD21 diesel. Yet to test this myself.
Intercooled electronic pumped diesel mistrals are '97 onward round headlight models. This turbo is particularly suited to if you are top mount intercooling (or are leaving crossover pipe) due to compressor housing exiting upward.
R50 96' onward terrano electronic pumped diesel turbo better suited to front mount intercooling due to compressor housing exiting downward or forward?.. maybe as they were front mount intercooled.
As far as i know both turbos are the same Garret GT2052 turbo on both of these trucks, just different compressor ins/outs. get whatever one suits.
The weaker unit is the hitachi HT12 on the WD21 terrano maybe because it has a ceramic exhaust wheel and non-ball (journal?) bearings and doesn't like 20 psi all day.
Hope this helps.
