Got a chance to make an aluminium air box today, features a 3" to 4" bellmouth to the stainless steel air filter. A short length of 3" silicon hose will join it to the turbo and cut out in the top will have a clear lexen top to ensure cooler air enters from behind the grill. Will polish it up shortly and manufacture a mounting system for the filter.



Thought i would add this just for interest sake. I manufactured a set of stainless steel extractors for a mates seirra with a swift gti 1.3l 16v engine and a toyota supercharger.
