    Default Looking for thin wastegate actuator for internally gated turbo

    I'm running into some space constraints on my car, the problem is the fairly large wastegate actuator, the diaphram part. Its thickness is about the same as its diameter and compared to the turbo (GT25) looks huge (and unessecary?). I can fit it, but have to move the dump pipe closer to the engine.

    Wondering if anyone might know of a common small turbo with a small actuator? I don't have dimensions with me but its about 60mm diameter and about the same thickness.

    you can buy those small T25 style/size ones for about 80-$100 beand new with an adjustable arm... being brand new and aftermarket the springs and diphrams are pretty solid compared to the 20+ year old gear floating around

    they look the same size as the one i have. I need a thinner diaphram/spring section, not really the arm.
