Hi guys Im new as you can see and about to be the proud owner of an STI

I've seen a nice 98 STI Type RA Version 5 Limited edition 48500miles all nice apart from a winning from the turbo. Can only hear it after about 2500rpm when driving. Its had some mods like inductions kit, back box and I seen paperwork for something called an airflow converter. dont know if thats what is causing the noise or maybe a leaking dump valve.

Anyway I want someone in the know to check it out. anyone know somewhere in Wales near cardiff that would check it for me?



Thanks
