THE DONOR CAR
The donor car.
The donor car that works in a FFR 818 can be any 2002-2007 Subaru WRX or Sti. I choose an ‘07 hawk-eye for two reasons. The first reason, it was the only one in the area I could find with manual transmission. The second reason, the ‘06-’07 engine is a 2.5L turbo-charged boxer engine with 230HP stock. This gives the 818 a power-to-weight ratio of 7.82:1 at stock power. That is nothing to sneeze at, considering the 1995 NA Miata (which dominates the autocross scene) has roughly a 12:1 ratio. My search for the WRX ended when I found the the one pictured on the left. I picked it up for around $6,000 and drove it home. It was a blast! I couldn’t fathom how fast it felt, also weighing 1500 pounds more than the kit would.
