I've been port and polishing heads for motocross bikes for years, my wrx spun a rod bearing so everything is apart. I figured what better time than to port the stock turbo which I'll use for another 4 or so months till I pick up a 20G? after a lot of man hours, I have the exhaust housing 90% finished. the exhaust inlet is all finished but the exhaust port still has some work to be done. I couldn't finish it because I ran out of supplies so I'll need to buy more in the next few days to really make this thing pretty! also found a crack on the waste gate hole which will need some attention before this thing goes back into commission. the intake housing will definitely get some attention once I get more bits for the die grinder. hopefully i see at least a minimal amount of performance gain from this itty bitty thing. here's some pics!
