Still stock at the moment, with the exception of a Bell regulator and a shorten throw on the waste-gate rod. I have assembled parts like intercoolers, a t03/t04b with H compressor wheel (lower output than yours) and a TWM Big-Throat throttle body. Still have to order the mandrel bent down-pipe and the IC piping and BOV from the DSM. I have the HKS pop-off valve coming as soon as Motorsports gets it in. I'm going to rebuild a lower end for the car with cast pistons, ARP rod bolts. This should be sufficient for what I want performance wise. I probably will get the SDS if this stock EFI doesn't stand up. So, the long version is a pile of parts, but hey I have fewer parts for this car than for the Pontiacs in the driveway.
