Outer Limits 4x4 Board

hey guys, just wondering how much power nd torque would be possible out of hdj79 with the 1hd-fte engine, 3 inch exhaust, rapid or dp chip, and maybe an intercooler if it will fit?

cheers josh

how much do you want? 180kW/550Nm at a guess without upgrading the turbo.

Different internals to the 100 engine, and Cooma diesel do a new grille with intercooler I believe.

Dtronic would be the thing to use, unless your not worried about smoke, fuel economy, or EGT's.

Some "chips" are just a potentiometer, just adding fuel, when wired into the fuel pump wiring.

up to 30 % increase could be expected below 2500 rpm, 10-15% up high.





79 Series intercooler kit
The 78/79 series intercooler kit is designed to fit the factory turbocharged Toyota Landcruiser fitted with a 1HDFTE engine, but will fit aftermarket turbocharged 75,78 and 79 series Toyota Landcruiser fitted with a 1HZ engine with only slight piping modifications.

Owners of the 78 & 79 Series Toyota Landcruiser Turbo Diesel 4WDs can fit the quality front mount intercooler kit to gain extra torque and horsepower.

The 79 series intercooler kit gives performance gains of around 20% to the factory turbo Landcruiser.

The intercooler kit lowers the air intake temperature significantly and does not impair longevity or reliability of the vehicle.

Included in the intercooler kit is a redesigned grill similar in style to the original Toyota unit, which gives the vehicle a tidy and professional finish keeping with the mechanical components in the kit

Your injection pump is the biggest hurdle. The highest I have heard of is 140rwkw, and the pump was maxed out. Lpg may be the go on top of that or revert back to a mechanical upgraded rotary pump.

that would be around 200kW at the fly, how much is enough?

140rwkw sounds pretty sweet man thanx guys!!

just fitted a 79series 1hdfte to my fzj105 auto wagon
stock except fot 100ser intercooler and 3" exhaust has 153kw at the flywheel waiting for dp chip to turn up but does it go returns 12l -100km as well

Similar scenario to mine in an 80 series. I'm returning that economy with it chipped up but no intercooler as yet. What was/is your standard boost reading at if you have figures pre intercooler.
