Both cars are extensively modified. The street car's drivetrain is from a JDM Mazda 323 GTR (1.8l) from the lugnuts to the intake manifold, with a factory GpA rear limited-slip diff, Whiteline swaybars, B&G springs, Tokico struts, Fidanza flywheel, ACT clutch, Porterfield pads, and braided steel brakelines. Both cars are running 323 GTR calipers. These are single piston setups but the swept area of the pads is large for a car this small. Most 323 GTR track guys look for other calipers because no one makes performance pads for these things, but I sent a dead pad off to Porterfield and they made me a custom set and there are no better pads that I know of... both these cars stop and stop right now! It's very difficult to fade these brakes. This is a good thing since the street car is perfectly willing to peg the speedo needle, well past the indicated 140.. Engine and turbo are stock (for a 323 GTR), but that means a VJ-23 ballbearing turbo, very fancy internally-curved intake manifold, forged internals, sodium exhaust valves, VLSD centerdiff etc...running on a Link ECU, RC 550cc injectors, Magnacore wires, lots of custom ignition mods, Spearco frontmount intercooler, TurboXS blowoff valve, 2.5" turboback exhaust, Magnaflow muffler, AEM wideband O2 sensor, etc etc. Currently putting down 320 whp/310 ftlbs @24psi. 2650 lb, it's a sleeper from hell. I just built a low-buck intercooler water spray setup so with that running, the new numbers are 333hp/344lbft....this is on a laptop datalog program.
