Trust me Stock is more then enough with your mods...Spend your money on something else..Maybe a hotshot header or something...

well the whole thing is my injectors are bad. so maybe if i thought if i replaced them then i might just upgrade them to something better. but i guess ill just go back to stock.

Get some new stock ones and you can send them out to RC and have them flow match and port them out..So they will flow abit more then stock..I sent them my stock sr20 370cc injectors and they made all of them flow around 410cc and all were within a 1-3cc of each other..

Not sure if you meant "new" or "new to him", but you can get used KA injectors cheap here on the Buy/Sell forums and then send them out for RC Eng. or DeatschWerks to do their thing.
