Re: [MV] M35 Turbo upgrade: Thermocouple and Pressure Gauge

With all this advice, I am thinking about going ahead with doing
a 'before' TC and also an 'after' one.

Question-- just how hard is it to remove the turbo mounting bolts
on the exh. manifold?

anyone's tales of this would be welcome!


intake looks easy - no heat no rust.
