fuel question!

oh man, hopefully I dont get yelled at for not searching cuz i did but was lazy to read through all the pages lol....sooooo

how much hp can the stock injectors hold? My goal is around 370-400whp on stock turbo eventually.

also I just put the walbro fp in and I read that just from simply installing it, it raises fuel pressure several pounds and it'll now be a lil rich...is this true?


thanks for the help!

thats true. the when i installed my walbro it made my car rich. as far as injectors go im not sure if youll be able to achieve that or not. you could upgrade them to like some 650 or 680s and have plenty to achieve your goal. but if you do upgrade then get a fpr as well that way youll have your 43psi of fuel pressure at idle. if you dont upgrade then get a reflash or use whatever(if you have anything like an afc, or piggyback fuel controller)you have to tune for the pump

well, my next mod is cams and I'll prolly consult the well experienced crew at AMS before I have them tune it so I know if I should upgrade them or not...

well if youre gonna install cams do that first before you get your tune that way you wont have it turn around and get it tuned again right after you get them installed. good luck and keep me updated
