But while the EH still looks the same as it did when the Noon had the keys, it now sports a healthy turbocharged Holden six under the bonnet.

Currently the drivetrain is the limiting factor in how much power a car can put to the ground. “I’ve got to do the driveline up front, because it still has an Australian four-speed and a banjo differential,” Corey laughs. “I actually blew the banjo to pieces and drove it slowly, so we’re going to put an M78 diff and Tremec TKO five-speed in it out of a VP ute. I got bigger brakes, new wheels, all that. will have to do”
“I wanted to do something different,” says Novocastrian and owner of the performance workshop Korteund. “The day I got beat by the Ford Laser was the day I knew I had to do something to it, so I did a 179 bore 60thou and a 350 Holley with a better head, making about 115rwhp. It was like that for years and I ran it daily before I put together the first turbo combo.
Once EH was no longer his daily routine, Corey began planning some form of forced induction for the Holden Six, but he ultimately left the decision up to someone else. “I actually asked my missus if I should supercharge or turbocharge the EH, and she said I should go turbo if I have to cut the bonnet to fit the blower,” he explains. “I didn’t want to cut any holes in the car because it’s special to me, so I went for a custom water-to-air intercooler. That way there were no cuts.”
Corey’s first turbo setup was pretty rudimentary, but after tweaking the combo a bit, it worked. “I grew up around Holden sixes, but I didn’t know much about forced induction motors when I first turbocharged an EH 10 years ago,” he says. “I bought a $300 T04/T3 hybrid turbo off eBay, plumbed it back to a 600 double pumper, made a manifold from a stempipe, changed the circulator and drove it around for a while.
Corey did all the mechanical work himself, including setting up the engine for full sequential EFI. “I machined the back of the flywheel for a 36-1 crank trigger wheel, and then I machined the fuel pump cam from the camshaft and a tooth to pass the signal to the housing sensor,” he said. Tells.
“It was making 187rwhp at 10psi, no intercooler. Then I added a water-to-air intercooler and it made 230rwhp just adding to that, so I put in a Garrett GT35 turbo that I bought from a mate and It made 279rwhp at 12psi, and did so for four years. It was a completely stock motor, with only a head and cam.
Turbo tech had come a long way in that time, so Corey decided to tighten up the combo by adding sequential injection and forged internals, but first he had to get a good block.
“I bought three WB Blue 202 short motors from a guy for $50 and found a good motor to make out of them,” he says. “It has a blue counterweight crank, spool rods, SRP forged pistons, main studs, ARP rod bolts and head studs, MLS head gaskets, but still has the original nine-port head and cam. I haven’t had it on the dyno yet, but it feels a lot stronger than it was.
The EH now runs LS7 coils, dual nose sensors and an LSA throttle body from a VF GTS, which Corey welded to an old can intake that he drilled to run LSA injectors. It also made its own crank and cam sync sensors to run a fully sequential EFI controlled by a Haltech Elite 2500 ECU.
“I’d have to say it’s probably making 300rwhp at 12psi,” Cory says. “I still have to add boost control to the engine, but the goal is to crack 500rwhp with it.”
EH has basically been in the Corey family since new, and has been a treasured gem ever since. “My nan bought it from her cousin in 1965 after her cousin had it for a year, and it was stock when she gave it to me,” Corey says. “I took it for a run in it on the old setup and it blew up.
