I need to do a comp test on my st205
Can this be done without totally removing the charge cooler tank? Can it be moved to gain access.
Any hints would be most appreciated.

Yes it can be done without totally removing the charge cooler. You have to unbolt it lift and rotate it - think there is a guide for replacing the plugs that illustrates how.

You really need to move the charge cooler to allow access for fitting the compression gauge. This isn't too difficult but it can be a bit fiddly dislodging the throttle body rubber hose and the turbo compressor hose to allow the charge cooler tank to be moved. The charge cooler coolant hoses might not allow you to move the charge cooler enough to fit the gauge so you might end up having to drain the charge cooler so it can be removed completely.

You won't have to drain the cooler you can just tilt it up out of the way. A block of wood etc is handy to prop it up on. There is a fair bit of flex in the hoses just don't be too vigorous with them as they will likely be 20 years old now.

Thanks for the advice chaps. Gonna give it a go... the lift and tilt option.
One thing... while doing the test was going to replace the plugs.. would grade 7 iridium be ok?

Standard grade is 6. Running 7 on a standard boost engine may foul the plugs unless you give it lots of throttle lots of the time.
I'm not sure of your engine/boost but if running higher boost at say 1.2 bar plus then the grade 7 seems a sensible route. IIRC I ran the grade 7 equiv denso iridiums when running 1.35 bar they were fine but at low boost during initial mapping they fouled and needed cleaning occasionally. (could have been the over-fuelling during mapping??)
