Hello lads, has anyone had there engine forged and still running on the standard turbo, if so I know there will be a increase but is there a lot?? I'm going to take my car to racetech next year to have the engine completely forged but I'm going to run it on a standard turbo for a bit then I'm not sure what turbo to go for, I have heard the garret 28 is a bit of kit, can anyone tell me??
