I've said this before and I'll say it again, and I'm really REALLY not trying to bust your chops, but the Clubsport, by its very nature, is a special car- it does not need to be modified. If you are planning on restoring it, unless this car was a total basket case when you obtained it, restore it to its original condition. I'm all for 6-cyl swaps and believe me, I would LOVE to see someone stuff an S65 into a ti, just to see what it can do, but if that's your endgame- buy a base, or active, or even a sport model that they made thousands of, not a model that they only made 300 or so of, maybe less than 3/4 of which are still on the road. Ti's were never meant to be high-performance machines- that's what Motorsport cars are for. That is all. </soapbox>.
That said, welcome to the .org! (I know, I'm a few months late...)
