The 2.8 build begins

no, Iain uses a company near him called impulse developments and swears by them, im certainly happy with the quality of their work but im strictly going on the appearance but i can tell a shoddy job when i see one, and ive had a few of them in sheffield which is why my fresh engine has done so many miles already without even turning a crankshaft lol.

was it setting the tappets a touch looser on the exhaust if your using a 6 branch as they run a wee hotter with them?

The standard valve grind is a single angle 45 degree affair, we opted for a 2 angle grind, 45 and 30 degrees, the 3 angle jobs work well but don't last very long due to the narrow width of the 45 degree sealing surface.

A temple special flywheeel is exactly what you've got on the 2.5 Si

I'm of the opinion that the 2.8 is a better engine than the 2.7, it's got more torque at low and mid revs with a broader power band, it was also more economical and responsive at low throttle openings than the Eta based 2.7 with 320i head.

Had to let it go, feeling the pinch with increased living costs (mortgage, petrol etc) led me to get a cheap diesel van to tool about in. I used it so much that the E30 was sat on the drive not getting used, I reckoned spending a grand a year on insurance and tax for something just sat there was a waste.

I've now got a bike which costs less than £300 a year to tax and insure, is much better on fuel , takes up minimal space and is a real hoot to ride.

Cheers,
