I've got about 550$, ive got a couple things on my mind as of what to do but im not sure, ive already got I/H/E on a B18B1, ive thought of getting some cams, buying a different tranny, probably b16, or getting a vtec head and getting the vtec conversion kit im not sure though yet

 

Perhaps something in the suspension department or a good set of tires?

 

1. Set of Crower cams
2. GSR transmission
3. Suspension, as Kendall suggested (start with the ITR rear sway bar ~$120)
4. Ditch it all and save up for a turbo.....
