Hey tommmo,
I was down at pauls not long ago while my daughter was hanging out with his daughter and stacey...he helped me with my vipec and added a boost switch for me. He spent more than a few hrs and I even drank his JD and coke. The point I'm making, he really goes out on a limp and simply knows his gtr's. If I ever had to rebuild a new engine, paul would be my 1st choice, there is no doubt about it.
Besides, does anybody know of any workshops that have close to 20 rb's being built, all from word of mouth? Imagine if he advertised and had a shopfront?
