Don't forget that the better the engine the more pricey the mods, but the end work is so worth it. Take your time and do areas or parts at a time. Save up and do full work instead of part work. Meaning instead of after-cat, save up for a few more months and do full exhaust. You'll be happier in the end..... A rule of thumb also is that performance and budget should be balanced carefully, the cheapest part might not be the most reliable part. But I guess everyone already knows all this forever repeated shit.
