what is the largest OEM longitudinal KKK turbo? RS6? Ko4? what are the options for picking up crapped out turbos and cobbling together a larger hybrid? there is a chance i have a soon to be dead turbo having ingested a spark plug electrode and now sounding like a constipated duck! I have a few people locally that have dead turbos and some with cracked housings, if I can pick up some cheap ones, find one with a decent CHRA and replace some bearings, seals etc. how tricky would it be to produce something that would be larger than stock for flow and A/R ? I have stripped a few turbos but in theory if you pull turbines and compressors off the shafts and match them to housings I am thinking it wouldnt be too tricky to match a better flowing turbine housing from RS6 or similar and mate it with a bigger compressor housing . I can afford to play around with compressor housings from transverse engines and mod an inlet mani, cant afford to be messing with mani and downpipes..... I never managed to sell my Eurodyne mapped ECU and 630cc file/injectors so I am thinking if I can pull together something that will sustain a bit more boost and not breach a late 200-300bhp I will get away with running stock rods and slap it on the downpipe I have. dont mind swallowing a bit of cost but this is a budget option!
