hi everyone, my bosch dturbo was tuned with what i presume is a stage 1 pump and turbo tune before i bought it, it normally boosts to 18psi.
around a week ago it started to drop to 15psi, then 12psi, now it is only making around 7psi and there is a loud whoosing noise i can hear from the cabin whilst driving. if i rev the car in neutral with no load on the engine it doesn't seem to make this noise.
i've taken the tmic off and this and the top rubber pipes look fine. when i look at the turbo from beneath the car it looks quite oily.
so on one hand i was thinking the whoosh sound suggested a pipe might be leaking, but then on the other the oily turbo suggests it's the turbo seals that have let go? would the latter still produce this noise?
i've tried to take a photo of the turbo but it's not great, is anyone able to identify what type of turbo i have here and from the amount of oil on it whether it is more likely the turbo itself, or whether it is more likely a split boost pipe hiding from me?
also if it is the turbo i'd like to replace it with a bigger one to give more power but on the tightest of budgets - are there any options that can utilise the standard manifold, oil lines, exhaust etc and be picked up cheaply on ebay or forums?
thanyou, and apologies for the long essay post!
