Car is running great, no problems!
Got these fitted now - Fluidampr crank pulley and lightweight alloy power steering pulley, both from INA:
I used new high tensile bolts and threadlock when fitting them. I have the alternator pulley as well but despite my best efforts, the original pulley refuses to come off - even using an impact gun and a vice didn't work! If I ever get it off or buy a new alternator, I'll fit it then.
The Fluidampr is amazing, it is said to reduce the clatter associated with single-mass lightweight flywheels .... and it really does!, Idle is smoother and quieter now and when getting on the power - it is just SOOO smooth! This thing really works, it's brilliant.
Lots of info about the Fluidampr here:

I don't know if it's because of the Fluidampr or the new lighter PS pulley, but my steering feels lighter and smoother now as well.
Did an oil and filter change today too (so now running Millers 10W40 CFS competition oil), along with fitting a proper Goodridge -10AN oil return hose from the turbo to sump, didn't get pics though, will get some soon. I'm now very happy with everything, so it's all set for some hard driving and FUN!
Big thanks to Issam (INA Engineering) for the parts and advice, plus great prices!
