CTN should be ok up to around 200 ish bhp. 65/68mm Pulley = 1ish bar boost.
Standard G60 box is VERY short on 1st, 2nd. It's a pain with a smaller pulley really, especially in the damp.
The longer 1,2, and 5 in the CTN is a bonus.
Interesting choice for a conversion!
How about building a 16v G60 ? Use the Bahn Brenner Kit? Not cheap though.
