    If that's a 2.0 engine they are outstanding figures, what's the specification of your engine?

    Yes it's a 2.0, rebuilt by Brett Sims motorsport, his head work and cam specs.
    I had been after a bit more torque.

    I replaced the exhaust manifold yesterday with a 4-2-1 Tony law set up as I think we can find 10maybe 15ft torque but lose 5bhp��

    Nearly 30 yrs ago we could n't get anywhere near those figures with a 2.1 NA Cosworth with a Millington head and various Cosworth cam profiles. We gained better drivability with a 421 Ashley manifold instead of the big 4 into 1 Tony Law.

    That's interesting to read, I no the head was a 4x4 to start with, hopefully my 4-2-1 manifold will make a difference, it's an angry engine for sure.
