Despite how impressive this particular 4G63 may be, it's only as useful as its turbo is capable. All is based off of a hybrid of sorts and began life as a Buschur Racing/Precision Turbo BR580 60-trim setup. Somewhere along the line the Precision turbine housing was swapped out for a re-machined Forced Performance piece that apparently outflows its Precision counterpart. All in all, 32 psi of crossbred boost is pumped out. The assembly hangs off the engine by means of a ported, second-generation, DSM exhaust manifold. The 2G manifold has larger ports and is less likely to crack in comparison to 1G pieces. The less restrictive design and 44mm TiAL wastegate lend themselves well to two-plus bar boost regulation. More Buschur Racing parts were added as the two-year buildup prolonged. This includes a 17x19x3.5-inch front-mount intercooler and piping setup that, interestingly enough, was fitted in such a way so as to not look a whole lot different than the OEM core.
Suspension, brakes, wheels and tires err on the uneventful side but; to be fair, suspension brakes, wheels and tires aren't the most important elements in terms of getting down the dragstrip, which, after all, is what Joe built his Conquest for. Nitto NT450-wrapped, 16-inch OEM wheels sit up front and a pair of 26x10.5-inch Mickey Thompson ET Street slicks occupy the rear ...full time ... no wussy street tires on reserve. Both cover up a pair of cross-drilled, slotted rotors and stainless steel braided brake lines from Goodridge. There's not much more to say here other than a KYB damper sits at each corner alongside Eibach springs and a Suspension Techniques anti-roll bar out back.
AWD Conquests/Starions are rare, and that's OK, Joe didn't want one. Such a drivetrain would only net him more broken differentials. Instead, his RWD was outfitted with a TH400 transmission adapted to the 4G63 by means of a Buschur Racing adapter plate. Rossler Transmission of nearby Girard, Ohio, reconditioned the automatic gearbox before Joe and ASE-certified brother-in-law Rick Ciolli bolted it into place along with the engine. For those who aren't in the know, the TH400, also endeared to as the Turbo 400, is not your typical slushbox transmission for those ill-inclined to manually bang through gears. The three-speed Turbo 400, which includes variants that date back to the mid-1960s, is nothing short of stout; it doesn't shy away from gobs of torque and, as such, affords drag racers a bit of longevity. It's strength comes, in part, from cast-iron center supports splined to the case itself that suspend the concentric shafts joining clutch assemblies to gears. Translation: TH400 failures are rare when compared to other competition-type gearboxes.
So just what exactly does 32 pounds of boost, a daily regime of C16 and borderline historic Japanese turbo car status get you? Roughly, 534 hp, 653 lb-ft of torque and an impressive 132mph pass clocking in at 10.32 seconds at the quarter-mile finale. Not too shabby considering the car's roots: a foreign automaker struggling for American footing paired with a U.S. automaker grasping for sales.
