I too need to replace my turbo on a BKD engine.
Turbo Technics quoted £425+VAT on a reconditioned unit with 2 years warranty and £75+VAT back if you send your old unit.
Midland Turbo quoted £185+VAT to repair (if no core damage) damaged turbo or £380+VAT for an exchange turbo with 1 year warranty.
So for an extra £300 Turbo Technics will exchange your damaged turbo for a new (?) hybrid unit.... seems the tastier option. I'll get a cheaper re-map from Shark Performance as I already have their STS unit. You reckon just leave the clutch until it goes anyway?
