Like I had said before I'm considering getting a WRX. I just found out that my car is worth about 18K so I'm pleased and there wouldn't be too much for me to finance. My question is around how much would it cost me (what would I need) to get 225 to the wheels of one with room to upgrade more? Longevity is an issue for me. I know that reducing the backpressure on the engine is healthy and frees up bhp at the same time. Any suggestions? I've looked at the link w/ the stages and prices but was wondering if anyone else has done it differently.
