My VR-s has a squeal (like a slipping belt) coming from the back center to left of the engine bay (warm or cold) when engine RPM is at 1300 to 2100 when driving and 1900 - 2100 when parked, clutch in or out. When driving if I keep the RPM steady around 2000 I can keep the squeal going.

 

So any ideas? EGR valve? vacuum line? or Turbo on the way out?

 

Car has a stage 2 ECU tune, single mass flywheel (rattle, rattle) has done 105kms (65miles) and is on its original turbo.

 

without hearing it i'd say TURBO

Egr pipe split or egr manifold gasket or turbo exhaust flange gasket. Might be soemthing loose.

The offending one will have a nice black marker lol
