IíVE LINED UP AGAINST MCLARENS AND 1000HP COMMODORES AND GIVEN THEM A PRETTY BIG FRIGHT
WHEN Dan McCosker wanted to go faster, he didnít look at making more horsepower, he went down the weight reduction path instead, building this mental 1JZ-powered Toyota Corolla panel van.
A lot of it was peer pressure to be honest!
My mate Kristian Goleby has one as well, and when I told him I wanted a lighter car to stick my Toyota 1J engine in he talked me into getting a Corolla panel van. The motor was originally in my old Cressida sedan, which was pretty quick, but when you stick the same gear in a car 400kg lighter, itís a whole other ball game. And it had to be a panel van because theyíre 1kg over the minimum weight to get the car mod-plated and registered with the turbo six-cylinder. I wouldnít have been able to get a sedan legal.
Iíve had it about two years now. I spotted it on Gumtree and it was just sitting in someoneís front yard as a parts car getting rusty, so I snapped it up, repaired the rust, then set about swapping the engine from the Cressida into the Corolla.
It was very hard. I had to cut out the transmission tunnel and firewall, then refill it with 1.9mm sheet metal to get the engine to fit in the bay. Then I got a set of custom mounts made by KE Conversions and swapped all the Corolla front suspension gear for the front end off a Corona. Not a single off-the-shelf part was used in the build and I did pretty much everything myself. I just went out and got a cheap welder and got stuck into it. Iím a diesel fitter by trade, so it wasnít a completely new thing, but it certainly wasnít easy fitting the turbo six into a car designed for a little four-cylinder.
The 1J is hooked up to the standard Toyota four-speed gearbox thatís had a new clutch pack and valvebody put in it to handle the extra grunt, and it uses a 3000rpm converter. It has a custom tailshaft rated at 1000hp, running into a HiLux 3.58 diff with a limited-slip centre.
The rest of the suspension is pretty standard, but I made a set of CalTracs for the rear.
Honestly, not a whole lot. Itís got a reconditioned 1J block from a twin-turbo Toyota Soarer with a stock bottom end and standard pistons and head. It has a single Precision 6466 turbo and one-off steampipe manifold, and makes 550rwhp on 26psi. The most weíve taken it to is 601rwhp at 30psi.
These things canít really handle much more
than 600rwhp before you have to start messing with the bottom end.
The best it has gone is 9.92@141mph on 26psi. It hasnít got a ícage or parachute so they kicked me off the track after that.
All the time! I quite often take it to Queensland Raceway for the practice lap sessions they have, and it blows most stuff into the weeds.
Iíve lined up against McLarens and 1000hp Commodores and given them a pretty big fright. Itís a lot of fun.
Iíve got the fuel system hidden under the spare wheel, so thereís no surge tank or anything weird in the cabin, and the whole build is pretty tidy. But touch wood, I havenít had any issues, and Iíve been driving it everywhere for a year! I guess they just donít notice it. s
