both ways have there own merits and there own complications. To be honest if 2K is your limit i would keep an eye out for 2nd hand units. Otherwise i would hold on and save a little bit more. 300bhp is very achievable but at a cost.. There is a vast range of super charger kits, C2 from us, and VF from NS etc. turbo kits for rhd will be available soon, but is not straight forward and the cost will prob be more than SC the car, due to the extra cost of additional parts to make things work reliably. Try looking at the vortech forum, lots of info there
