Honestly, if he's giving you $5000s toward the car, but won't let you do performance stuff to it, then take that money plus whatever money you were going to spend on the car, and buy something faster....like a GS-R or something. If you're not going to put money into performance in your civic, its going to be slow....stock Civics are slow cars, no getting around it. Pick yourself up something faster. Stock verses stock, an Integra (especially a GS-R) will out performe a Civic in most aspects.
