I am up in Perth so if you can get the car trailered to me I will soon get it running for you.
If you do not have a trailer then Nobles at Loanhead, Edinburgh would be a good shout.
I can easily do this for you on an exchange basis or buy outright.
Do you require a full CNC Ported Big Valve Cylinder head job or just a simple port and polish to improve flow?
The service that I provide is based on the VQ35DE Cosworth design, which I have on my own TT 350.

Just carry out a bounce test on a flat bed ramp applying liberal amounts of WD 40 or similar at the same time to the suspension components. ie springs, arms, bushings, mounts, drop links etc. etc.
Chris,
More than likely it will be the compression rod ball joint (banana arm) so this would be a very good place to start, however difficult to find play with a pry bar.
Plenty in stock if required, just drop me a PM if I can help further.

All SMFs chatter (gearbox idler) up to circa 1500 rpm. some more than others.
If your engine is "labouring" on idle you will get a chatter from the drive train.
