I thought they stopped making the 52? I have heard good things about the Blouch's but don't like the damn near 2k price tag. I'll see If I can have the 8cm hotside put on with a clipped wheel. It will pretty much be a new turbo at that point... have no idea how much more it would flow tho. I want to put 450 down on 100 octane... close to 500 on C16.
