I've just recently purchased a mk2 fiesta st for mysecond car, I've never had a turbo car before and was really just wondering what care needs to be taken when warming it up and cooling it down, and whether it was worth getting a turbo timer fitted? Any help is appreciated

Best thing is to keep the turbo underworked until the engine is warmed. i.e. dont go drag racing on a cold engine.

Beyond that, the less work you make it do the longer it lasts. so if you drive around with a 30psi boost all hours of the day its going to burn out much quicker than if you keep the boost down.

Thanks for that I let it get to 4bars on temperature before I let turbo kick in, just don't want to damage my pride and joy

normal driving change gear at 2/2.5k revs that will keep the turbo on boost but not under to much stress. Then when it's warm and u fancy giving it some you should be fine as most modern turbos don't need the extra care that the old ones did. If you have been having a little fun before you stop the engine it's best to let the turbo cool on tick over for a little bit or just some gentle driving before you shut the engine off. Good quality fuel will help as it burns cleaner so will help by not choking up the air path of the car.

also dependant on mileage, it could well be worth getting it a terraclean service and an induction cleaning. The terraclean is cheap enough (averaging 110 quid) but is bleedin good (I had it done last week on my car at 125k!) the induction is a service some garages will offer, and it cleans all the inlet manifold, turbo, basically any cold part of the engines internals it will clean them!

Thanks everyone that's how I've been driving really changing gear steady usually stay in 6th just cruising at 30 and fill up using vpower seams to last longer aswell. As for the terraclean my cars only done 6k so not sure if it's worth it. Thanks guys

A MK2 Fiesta? Don't you mean MK7?

It's a mk2 fiesta st but mk7 fiesta
