The wrx in my garage makes over 500hp and has a stock flywheel in it. So I see no reason for you to spend the extra money.
Looks like an awesome build. I have a PSM bug eye Sedan. :thumbup: Doing any head work on the ej205 heads?:Update:
Finally, after having a couple engines sold out from under me, I got a "new" long block. It's an IAG built EJ257 with ACL Bearings, Nitrated 2011 STi Crank, and Manley Rods/Pistons with EJ205 S20 WRX Heads.
Hopefully I'll be taking delivery of it next week so I can finally get the car rolling again.
