Damn! Is that 90 bucks a piece for the injectors?? They are high quality, but damn.

Bigger injectors alone won't do anything for your engine performance besides degrade it and make it run rich. You will need some modifications to go along with it and a tune....

Like wat? I have every bolt on u can think of and I am tuned, after I get bigger injectors I should get tuned again?

[blackice]

bolt ons as in....intake, header and exhaust? you should be fine with a tuned p28 then. if you are worried about your injectors send them in for a cleaning and bench flow at dr. injector. if you are doing internals such as high comp pistons, cams, etc then you might actually need and be able to take advantage of bigger injectors. i'm just saying you most likely don't need upgraded injectors yet unless your tuner says otherwise. imo spend the money on your next mod such as cams and valve train, euro-r manifold, s2000 throttle body etc. about your tune...if you go get bigger injectors anyway yes you will need to change your tune. the ecu is currently set to handle the 345s....

H22's don't need bigger injectors until they reach 220ish whp.

fuel rails, adjustable fprs are a waste of money, especially on anything under 600whp. Unless you need a special rail for the EuroR.

[deevergote]

Exactly. There's no need to upgrade the fuel or ignition systems until you have considerable mods done already. Larger injectors will only run rich, and create potential tuning issues, as the stock ECU isn't prepared to handle a different size. It probably won't hurt anything, but you're looking to spend $400 on new parts that aren't going to help, and may very well hurt performance.

If you want to replace your injectors as preventative maintenance, that's fine. Preventative maintenance is ALWAYS a good idea. However, replace them with stock ones. Send them out to get cleaned, flow tested, and even refurbished if you don't buy brand new.

If you can afford downtime, send your injectors to www.cruzinperformance.com to Rich and he can clean & flow test them. He also can install new seals and injector filters on them, they'll be like new. Honda has quality injectors, they last a long time. Going to something else with an otherwise stock motor can cause problems, besides you should retune for the larger size, which involves more cost.

They're still cheaper than even Majestic Honda! Item #1

Majestic price $109.22

Thanks Cisco. I searched through your old threads and our old conversations, and I couldn't find this! I knew you had told me where to go in the past!
