Right been a busy little bee this weekend. All started like this :drunk2: 1stly the mani. Autobahn manis are so shit it's unreal. I hade seral engineers look at it and they all said it was extremely poor quality. The welds, the brackets every bit of it. After pulling all the mani and turbo off i found a good few cracks that i have had to get fixed. The surface that sits against the engine has also been skimmed as it was half a mm out wich is massive in engineering terms. Anyway here are the results. Before After Next the turbo. I have ported and polished the internals. The exhaust side has been opened up massively to improve flow. The wastegate has been ported properly so i avoid any boost creep and hitting fuel cut. The difference is a good one. The boost comes on a couple of hundered revs earlier and is nice and strong all the way to the end of the rev range. Here are the differences in the standard and my one. Before After Then it all went back on again and then everything is perfect :surrender:. Bourkey
