I'v been going through the same dilema and I weigh more than you. Here are your options.
1. 1440 stroker kit, head and cams, exhaust, air fitler, pistons=215HP $5500
2. stage 1 turbo on 08, straight bolt =230Hp probably cost you $5000 with install and tune and then hope you don't mess it up
3. Turbo set up, intercooler, motor build,= 300-350HP on pump fuel, prob looking at $10000+ little things extra you don't initially think about.
No guarantee any of the above will not mess up. Some have big bores and turbos that have high miles some have setups that blow up after 5Kmiles. Just don't go turbo if your not willing to learn your setup and do routine maintenance. I would say a turbo setup is not something you just ride, wash and put in the garage. Some will argue it is but I've been extensively researching this for the past 6 months and have talked to lots of people who own these setups and this is the overall census
