93 Navara
Morning all,
Looking at upgrading the Navara to a 1HDT 80 series and hoping for a bit of
feedback. I've heard good things about these motors (barring big end bearings), all be it that they are a bit gutless pre turbo kicking in. Spoke to AXT turbo recently who advised against intercooling them, and instead replacing factory turbo with larger garrett job. He believed far better power increase for similar investment. Hoping someone may have done a similar upgrade?
The other option is buying a low km 1hz 80 and doing the turbo kit in full. The 1HDT appeals a bit more to me as the fuel pump has the factory boost compensator. AXT are talking about 20% improvement with garrett unit.
Look forward to hearing your replies.
Ben

My parents have a 80 series with the 1HD-T, Auto transmission
Fuel Economy highway run is 8.6 km/litre (100km/h)
Has good power through the rev range
These motors put out 115kw standard
My old 1HZ turbo 80 series was around 130 - 135kw
Fuel economy 7.5 - 8.0 km/litre (sometimes 8.6km/l)
You can get boost compensator fitted to the 1HZ motors i think the cost is around $1200, The only job they perform is to reduce black smoke. They may give slightly better economy
