My turbo blew at 50k. I recently bought a td05h-20g turbo on ebay for $250 + $50 for shipping. MY wrx is completely stock and this turbo is capable of supporting 440hp w/ the internal waste gate set at 9psi. I did want to do some upgrades at some time and since the stock turbo blew I figured this would be a good time. My question being is this a good turbo for my car and should I increase the waste gate pressure? I have no knowledge about turbos, this is my first turbo car. I do love the wrx but i feel it could use a little more power so any advise would be greatly appreciated.
