GRJ series 7, good engine? (1 Viewer)

[Marco Italy]

I recently replaced my trusty HZJ 78 transformed into an HDJ with a GRJ 78. 4x4 for trips to Africa and Asia.
Do you know if it's a reliable engine?
I read this and it doesn't sound like good news to me

Been in the current 4Runner since 2003, 2005 till? Tacoma, and FJCruiser. Haven’t really heard much problems with this engine. Being a Toyota engine I would assume a new one shouldn’t have any problems anymore if there were any

Sounds like you transformed your HZJ78 into a GRJ78.

I assume this was out of necessity as Toyota already made an excellent vehicle for trips into africa and asia when they put a 1HZ engine into the 70 series. If you were looking for more power and still maintain reliability and longevity, you could have put a turbo on the 1HZ, or if it needed to be swapped, then swap in a 1HD-T

My wife's tacoma has that engine (the updated VVT-i) and it is ok... consumes fuel like an alcoholic, uses a bit of oil, but otherwise it seems to carry on, currently at around 180,000miles/300,000kms. Like they said keep some of the common failure components handy (water pump) head gaskets, etc.

If it were me, I would stick with the diesel for long trips and adventures...

hello, I wrote wrong, I had a hzj 78 transformed into hdj with 1hd engine and ct26 turbine, h150f gearbox, because at 57 thousandkm the 1hz engine to which I added the turbo kit broke 2 pistons and r151f gearbox. after the transformation into HD I shot for many km in Africa with my 78
now i bought a new 2022 grj78

Hello,

The 1GR engine is reliable.

If you watch your speed and rpms it is not a thirsty engine. Remember, on a gasoline/petrol 70 Series you are wasting fuel if you exceed 90 km/h.

Provided you stick to the maintenance schedule and avoid messing with the electronics, it will provide years of reliable operation.
