Phil,

As you prob already found out, if you ask different people, you will tend to get different answers.........

Can Mark Shead not give you a definitive spec for the turbo required for the job that you want your engine to do??????

Otherwise it's looking like you've made no progress since the first of these posts over 2 months ago:

"GT35 or GT40 or 42???"

"Just ordered my rods and turbo delivered"

"GT35 on it's way!"
