  1. The car is a 1993 R32 GTS-t, mods are: S1 RB25DET swap El cheapo T70 turbo @ 23 psi El cheapo 38 mm gate El cheapo high mount manifold Bosch 044 in-tank job 3" straight through zorst ARC front mount intercooler Pod, BOV, etc Stock internals, stock injectors, stock fuel pressure reg, stock ecu (tuned by Garage Saurus when in Japan, but). The car made 196.7 rwkw @ 14 psi, back before we had the 3" on it (had stock exhaust with chopped/changed bits and big restrictive dents) The 3" brings minimum boost up to 23 psi (tiny 38mm gate is fully opening, can't bypass enough exhaust, strange). Fuel hasn't been an issue yet, the tuned ecu coupled with the RB20/25 airflow meter sees the airflow meter max out and the ecu starts dumping all the fuel it can, pretty much 100% injector duty cycle. On the dyno run we were seeing 10:1 AFRs pretty much the minute manifold pressure went positive hey. Now that we've got the 3", and the boost at 23 psi it's running well fast, seat of the pants dyno suggests around the 250 rwkw mark, with boost hitting HARD at about 4000 rpm, watering off toward the high revs (maybe down to about 20 - 21 psi). Blows away XR6 Turbos with ease. Bit of fun! Microtech is next on the list, followed by RB20 fuel rail and some top feed 550cc injectors or something like that. Leaning up the mixture should help us make a fair bit more power, I'm hoping.
