Roger. I'd run 24/0 if I didn't have a timer too lol.
Just remember the rule of thumb. In your case, if you grow it to 8", it will finish at about 14-16". It's case by case scenario. I have to wait for mine to get to 20" before I switch over. They land at about the 42-44" range for me once done.
I did the subaru thing for a number of years. I've had a 90 loyale, fabbed a lift kit for it and took it out 4x4'n. Had an 88 GL with 2.5 RS drivetrain swap on a lifted chassis, divorced tcase, etc. That 4x4 wagon was bad ass. I also had a 2000 RS that was built with forced air tech twin turbo, eibach coilovers, big brakes, injectors, blah blah blah. I wrecked that hitting a moose at 110mph. Needless to say, that was like hitting a full dumpster. Rolled and flipped that car into submission. I also had a 2006 STi. That thing was simply badass. Sold it because I knew I would go to jail if I continued to drive how I was. I also had a 86-87? BRAT with the jump seats in the back.
So, I've dealt with EA81, EA82, and EJ25 engines. Turbo and non-turbo. Just got done with a friend helping him do the STi swap in his 2000 RS. It's called the RSTi. 2 door RS with STi drivetrain. Also did a 2002 WRX drivetrain swap into a 1994 impreza L. swaps included everything, motor, tranny, rear end, computer, wiring harness, etc.
Ohhhhh memories. I've often thought about building another offroad subaru. Those were a lot of fun.
