Happy New Year Everyone
I need some guidance. I own a 1989 HJ60 Landcruiser which I bought about 15 months ago. Spent some money on it with a few mods but I have an issue with performance. Off the mark she is like a bull at a gate, but she can die going up a hill. Now I know the old girls can die going up hills but I have a second one which is an 85 model and she just doesn't back off. The thing is the 89 has a set off extractors on and a bent mandrel exhaust system yet continues to fall short. I had toyota go through it when I first purchased it, Could this be an injector issue and if so has anyone got any advice of what I can try before I get toyota to service the injectors as they are quoting $1200.00 to do it.
Regards

HNY Robert,

Was she a slug going up hills when you brought it or has it only happened recently? Are the weights the same it the two cars?
I would also look at getting a dyno done.

Cheers and happy new years.........Steve

Except for a set of ply shelves they are the same. I am running Cooper St's on the 85 and the problem vehicle is running Mickey Thompson MTZ's. The vehicle did not show signs of being slack on hills when I first got it but I was so busy ironing out all the other bugs like leaking axle seals and I cant remember doing to many hills to be honest, I might have missed it.

This may sound silly but have you changed the fuel filter?

No Volvo driver both are naturally aspirated. I like'm that way. I put my youngest son in the 85 model. The 85 model I bought first and when I drove it in the driveway for the first time the son went "I like that" and before I blinked it was gone.

Hi,
I have had a few diesel 60 series over the years and for some reason the up to 84/85 models went ok, in fact in forth would almost go to max revs on flat road which was about 140 to 145 kmph running 10R Desert duelers mainly.
I worked for a four wheel drive hire firm for a shortwhile in 1989 which had 75's ,60 's etc and they all battled to better 115 kmph under same conditions. I did speak to the mechanic at the time thinking they were restricted but they had not been retarded by the business.
I dont know why but this was my experience with these cars.
Sounds the same as your saying ,my guess is they changed the fuel pump settings.
The best HJ60 I had was a 1982 4 speeder which had nearly 300kms on the clock and would pull out to better than 140 kmph.
I used to deliever the hire cars to mine sites etc and ran them flat out for miles but no better than about 115 to 120kmph if you were lucky.
Regards Alan.

Hi westozal
My networking has told me the same thing. Frustrating but I will keep trying. She has 310,000 on the clock and off road she is the goods and I suppose thats where it counts.
Thanks

1st thing I would do is to get someone else to service the injectors.
Toyota most likely send them out and add their cut on top.
I think $400-$500 sounds about right for 6 injectors.


I would take it to a diesel shop and have the pump and injectors serviced and dynoed to test HP
