Im on the fence, ive been quoted 15k through a renowned garage in brisbane for a TT setup after 2 hours discussing options etc and bringing in my tonne of research, Ive been recommended to ERD and GT Auto. Supercharger slightly less figures (especially if you can gather the courage to install yourself), running kits around the 5-7k mark, labour, tuning (been told the Haltech Plat Pro). However, I know of a couple blokes whose engines gave out on the SC not long after, guess the VQ is a give or take on FI :S Let us know how it goes mate
