My turbo has started showing the signs of leaking oil seals which is the ideal excuse to upgrade. I dont want a VXR one as they seem to be just as gay as the standard ones so was looking at something a bit bigger. Ive seen a few people on migweb use ebaytech specials and use t3/t4 hybrids. My knowledge on turbo sizes and fitments is pretty much nothing so what would be needed to fit a t3 or gt28 size turbo to my astra? And how much power can I run before the internals decide to become externals?
I had looked at T4 size turbos but they look massive.
