Hello everyone - New to the forum and finding it very helpful and entertaining. Hope to be a regular visitor and perhaps even contribute if possible but my mechanical knowledge is very limited. Looking for some help if possible. Recently bought an immaculate 1999 UK Impreza turbo with only 56000 miles on it. Very pleased with the car and it's everything i'd been looking for but today had no turbo. Boost was completley non existant even with warming the car up properly. The cars has a few mods but nothing over the top, STi intercooler, Viper induction kit, HKS dump valve and a recent new TD05 turbo with professional remap. Any suggestions?, was fine yesterday with no hint of a problem. Look forward to any help/advice or suggestions, thanks. Garth.

 

Check all pipework.

 

Checked all pipework/hoses, everything seems tight and secure. Have given all jubilee clips a wee tweak. Will go for a decent run tomorrow and see if any better

 

Turned out to be the wastegate had jammed open. Had opened up past centre and got stuck.
