nah, you didn't sound gruff - I know what it's like when you've made up your mind about one thing, and people keep saying "but but but but" and you don't want to know about it...

however! helicoil wouldn't upset the seal, the amount of of material lost is negligible. Normally coat the drill with grease and run it slow, take it out often to clear the swarf. Do the same thing with the tap, coat it with grease and take it out often. If there's anything left in the hole when you're done it's easy to pick out with a bit of MIG wire

What's the upgraded turbo worth? I'm happy with the stock performance of my car, it's my daily and does a 70km round trip. Maintaining *reasonable* fuel economy is important so I don't think I'm going to do anything with tunes or upgrades any time soon. I know what you're talking about with the 6000rpm range though - it really does run out of puff over that... I've no idea where the limiter is, but it certainly doesn't drive like it wants to go bashing against it.
