if you just want to use the 1000 now then u could get all the usual bolt ons, OR you could save up more n go with a turbo or an engine swap.

alot of people i talk to now wish they hadnt bought all these bolt ons when they coulda just gotten something that would increase horsepower dramatically. Cuz you cant use say a DC header with a turbo and if you got the engine swap you couldnt use that header for that engine either. unless you made some ghastly mistake and bought the same engine
