HILE he sells new Volkswagens
during the week, Brisbane’s
Ben Horsfall has a very different
turbo six-cylinder to take out
on the weekends, with this 350rwhp Toyota
1JZ-powered HZ Kingswood in his shed.
While everyone seems to be going nuts
for LS1 and Barra swaps, punters shouldn’t
forget Toyota’s venerable 1JZ and 2JZ turbo
six-cylinder engines, with their ability to take
boost and make horsepower like no other
production motor of the 1990s. But Ben is
the first to admit he’s no Toyota fanboy.
“I didn’t do the build,” he says. “I found the HZ
for sale in The Trading Post already done and
bought it. The guy was in a motorcycle accident
and never got to use the car, unfortunately. I
have an HZ styleside ute with a Holden 253
in it, and I initially bought this sedan to put the
V8 into, as the ute is just too rusty to work
with – I have been quoted around $18,000
just to fix the rust!
“The sedan was sold to me not running,and my brother, who is a Nissan Master Tech,
convinced me to get the 1JZ running,” Ben
continues. “All the fuel lines had perished, the
crank angle sensor was stuffed, the lift pump
and external fuel pumps were both seized,
there was dirt in the fuel tank, the ECU’s
internal battery had died, and the original
turbo’s seals had all gone and it was pumping
oil straight out the exhaust.”
The 2.5-litre Toyota 1JZ-GTE in Ben’s sedan
has copped a high-mounted Kinugawa turbo
that uses TD06H internals and exits via a
three-inch exhaust. It is backed by a W58
five-speed transmission, with a button clutch
joining the two, and a locked Ford nine-inch
down the back. The donk is controlled by an
old Haltech E6X ECU, while there is a custom
lift pump in the stock fuel tank and an in-line
Bosch 044 and surge tank living in the boot
with the relocated battery.
“I had it tuned by 999 Automotive in Coopers
Plains and it is fairly quiet and unnoticeable
until I give it a bootful!” Ben says. “Once itgets to about 3000rpm it kicks off and goes.
It’s made a best figure of 256kW at the wheels
on the 999 Automotive dyno, and cuts boost
at 21psi – it gets there pretty quick!”
Behind the stock pie-tin hubcaps there
are disc brakes on all four wheels, and the
suspension is pretty much stock. While
we reckon it would be an ace Powercruise
weapon, Ben hasn’t worked out if he is
going to start screwing more power into the
four-door.
“I haven’t really decided what to do with it, as
it has only been driving on the road in the past
few weeks; when these photos were taken
I’d had it on the road a week,” he says. “I have
decided to keep the 1JZ in the car, instead of
changing it back to the V8 from my ute, though.
“The sedan needs a little more work if it is
going to be used as a race or event car, as the
current set-up is more suited to regular street
use or being a daily driver, even with the locked
diff. One problem is that as soon as I go to
hammer it, it hits boost-cut!” sBEN HORSFALL
