(alrdy gettin the arp head bolts) yeah it would be nice to give some info performance wise also. but this is gonna be my daily driver so nothing too insane. im also sort of on a budget but give me all the opinions you have to offer. thx alot

Agreed timing chain. Assuming you have an S13 SR, maybe upgrade to S14 water pump, that's pretty cheap. Clean the head up of any carbon or anything that's in there. If you don't already have RAS somehow, do those as said above. And whatever that's cheap that you can think of.
