I've already driven my 02 wrx wagon over 4,000 miles since the ej207 swap, the miles really pile on fast been my daily driver. I can honestly now answer the original poster question on this thread. Do I regret not having built a 2.5 instead of going with an ej207 ? No i don't, I definitely made the right choice. With the help from people here ( you know who you are that helped me) and the swap process I've learned a great deal. Thank you very much, my swap is a complete success. My bugeye is an absolute pleasure to drive, I look forward to it every day. My next ej207 swap will be when the time comes to replace the engine on my 05 Saab 92x aero, my saabaru.
