This is James' ride, a rather nice BT1 turbo. It has come a long way since when he first got hold of it a number of years ago. The entire car has basically been rebuilt, but as you will see, the results are impressive...
First on the list was to fix up the paint. Not just any touch up though, the car was stripped back to bare metal, as was the interior and the engine bay. Everything was repainted in 2pac silver which really makes it stand out on the street. All of the window trims were painted black, like they came in the Calais, to blend in with the darkened windows, thanks to some brand new tint. Along with the new paint, all new bumpers, trim, lights front and rear were replaced with genuine stuff to make the car look like it's brand new. Along with the paint job, a VL group A front bumper was added, as were the bonnet scoop and rear wing to give the car a bit more definition.
Now that the motor was out of the car while it was being sprayed, what better opportunity to do a few mods to the engine (how many times do we hear this?).
The motor was originally built so it could be run with NOS, but so far no NOS has ever been used. The standard pistons were replaced with Ross forged items, as were the rods, again with Ross items. The single cam head was then flowed to substantial numbers by the local pro to ensure the "best possible flow scenario". The turbo which was already on the car was reused with the new motor. This turbo is a hi-flow T03 unit with T04 bearings, prop and massive wastegate, which was sourced from AVO for quite a few bucks.
A few other AVO items were used in the motor. This include one of their "stage 3" cams, a stage 2 intercooler and a AVO boost controller. The air mass sensor was modified to accept more air which comes from the standard air box. A cold air feed which is located in the brake duct leads to the bottom of the airbox, which obviously has a big hole cut in the bottom of it.
On the other side of the motor, the exhaust exits through a 3.5" system to a modified cat and the rest of the system is also 3.5" in diameter.
The gearbox was a stock MX7 5 speed unit which sends the power down the stock tailshaft to the VL turbo LSD with 4.11:1 gear ratios to bite the road hard. The stock brakes, themselves very good units, still handle the stopping duties. The car is now lowered all round with a panhard rod out the back as well to keep the diff fitting correctly. This makes driving the car a treat, and along with the 17" clubbies, make the VL look pretty sweet as well.
Once the motor was rebuilt, an initial tune up session recorded 230hp@wheels, which left James pretty happy for an initial kick. But it hasn't stopped there. Since the first tune, 6x 024 injectors have been installed to replace the stock units, which were deemed no longer able to carry the necessary fuel needed for the motor. A hi flowing pick up pump feeds the 600hp Bosh pump with Bosh adjustable fuel pressure regulator are also included into the equation.
More progress was going to be made with the car being able to be tuned better, so the stock computer was replaced with something better suited to the new engine, in this case James chose a Haltech E6K over its adversaries.
The MX7 was then replaced with a fully beefed up Jatco 3 speed automatic with 3000rpm stall converter. This was because the car previously blew 2 MX7 boxes and James wanted the start using the car on the strip a little more, so changing to an auto seemed the way to go.
The motor was then re-tuned, netting a very health 300 horses at the treads. The car was then taken to the track for a bit of fun where it recorded a very tidy 12.5 second pass at Willowbank Raceway in full street trim, and yes that is on street tyres. James was pretty happy with that! And that's how you see the car today.
