Well once again i have a 97 civic hatch with an ls/vtec swap. It feels suggish as I go up in RPM's. Apparently I am running a 12:1 compression ratio and i think im running lean with stock fuel system. Would it be safe for me to install the 97+ h22 injectors I have right now. I do not have any type of fuel management but i do plan on purchasing a vafc as soon as i get the funds and getting it tuned. I already changed out my fuel pump to a 255lph and I do have a B&M fpr (I know it sux). I have a a/f ratio gauge (I know its not accurate) and an exhaust temp guage for monitering right now. And by installing them will it make me run real rich? This is my daily driver and I want it running better than it is. Thanks in advance

Yes, it'll be fine to run the prelude injectors. The 97+ lude injectors are 290cc's. It'd be optimal to tune it rather than just throw 'em in if you want to make it run it's best.

Well what I mean by running better than it is is sputtering as i go up in RPM's. I just want it to run without sputtering.
