Always the correct part
We know our products
Mounting, Balancing
At TSR we pride ourselves by the fact that all of the high level, specialist components we sell we've actually used, driven, raced and dyno'd these parts to prove to ourselves the real world performance, this puts us in the perfect position to be able to advise our customers correctly first time round exactly what they should purchase to meet their end goal, and that is exactly the same when selecting a turbo.
We have proven on many occasions just how well the G25-550 turbo works on the 1.8T 20v Engine, providing rapid spool earlier in the rev range compared to the older generation of turbos, yet still being able to deliver the headline power figures we all want.
Engine spec and hardware will greatly influence the final power figure, but in our experience this turbo is suited for anyone looking between 400-500bhp using pump fuel, and up to 550bhp for extreme builds utilising race fuel and direct port Methanol Injection.
It is our preference to use an External Wastegate setup, so this is the spec we supply.
