1999 Subaru Impreza 2.5 RS -->  Version 6 STi Hybrid



This is the second GC in the family. Its heart came from my Group N GC STi which was originally a Version 6 STi RA Limited. Plan "A" involved using all Ver 6 STi parts. I had everything except the intake manifold and wiring loom to complete it. A company was able to source a version 6 loom from gr8wheels, but 2 months later (during the swap) found that the loom was corroded. Plan "B" to use USDM WRX parts to finish the swap. Sourcing another Version 6 harness wasnt looking good if I wanted the car in a timely fashion. Below you will see the parts used in order to get the long block to work. I was hoping for a replica of my Group N car(Rolling spare parts bin), but in the end I ended up with a car thats more reliable for daily purposes. Its still has pleanty of spares to compliement my other parts bin at a rally.
