To get rid of the minor scoring on the cylinder wall, the machine shop steam cleaned and magnafluxed the block. They also gave it a full blueprint and mock up assembly before chewing up and spitting out enough cast iron to give the block a .020 overbore. Of course, the JE forged pistons had to be .020-over to match the new bore. Beefed-up rods come from Crower while ARP supplied the main studs. CAR V2 then assembled the engine to ARP/Crower spec with ARP fasteners. The valves and retainers remain stock as do the cams on the 2JZ-GTE while the head has been race ported with a three-angle valve job with OEM guides and seals.
All this extra strength does have a purpose. With the slew of additional bolt-ons such as a fuel pump and intake from HKS and a three-row, front-mount intercooler and wastegate from GReddy, the 2JZ-GTE is ready to unleash more than a few extra horses from the corral with the help of the massive GReddy turbo.
Bombka and team opted for the T78 rather than the T76 because, well, it's bigger; and bigger is better.
At the end of the day, this formerly dilapidated '95 Supra is churning out 656 whp at 27 psi. "I felt that more power could have been made," said James. "But the boost kept falling off past 6500 rpm." With an engine as impressive as this, the interior might be considered an afterthought. Here, it's just the icing on the cake, and very sweet icing at that.
When Turbo first came across Bombka at Extreme Autofest it was partly because of the large crowd gathered around watching a dirty DVD playing on one of the many screens in the cabin and trunk. Just as "inspiring" as the DVD was the fiberglass job encompassing all of the electronics. Painted in candy orange and white to match the exterior, the cabin is nothing if not immaculate, almost as erotic as the DVD.
Aggressive rims and tires compliment Bombka's bomber almost as much as the interior. There's nothing like three-piece 19-inch OZ Superlegerras to fill out the arches of this widebody, especially when they're 10-inches wide up front and a crazy 13-inches out back. They ride on are Tanabe coil-overs while Eibach sway bars stiffen things up front and rear. Of course, with all this power a compatible set of stoppers is required. A set of cross-drilled rotors with color-matched calipers bring the Supra to a stop when so desired.
Bombka and his Supra are on the dyno regularly tweaking that horsepower figure. Future dyno runs could easily see 800 hp. In the meantime, Bombka can't complain, he's got another project Supra that promises to be just as evil as this one. And they're both a long way from that little Czechoslovakian motorbike.
