im new to this stuff i have a 95 honda accord ex 22 vtec f22b1 5 speed i have a cold air intake, header, high flow cat, 2.5in catback n1 style, also have halo lights and altezza tail lights i am ordering coilovers and skunk2 struts i wanna put bigger injectors in it it has stock now whats a good size to go to i was thinking 440cc or 550cc is it worth putting bigger ones in will they work with my stock ecu or do i need to buy a chipped ecu also do i need a bigger fuel rail i searched all over this forum and couldnt find any thing about this thanks for all your help

 

no need for bigger injectors. You don't have the supporting mods for bigger injectors.
stock fuel rail is good up to 400-500hp. Aftermarket fuel rails are more or less for looks. They CAN help if your running high hp but for anything up to the 400ish 500hp range stock works just fine.

 

Thanks For reply so injectors won't give me any extra hp or any better acceleration also what about a chipped ecu I found one on eBay for like 300 said they will program it for my mods what r ur thoughts on that thanks again for ur input

 

since you have a 95 you will need a obd2 to obd1 conversion harness. Then you will need a hipped p72 ecu and either a street tune or a dyno tune. Pre-tuned ecus aren’t what you want. you want a tuner who is tuning then actual mods you have. Not all intake and exhaust flow the same.

 

Ok thanks for your help

 

i looked up a chipped p72 it says its for a h22 intake or a gsr i have an 95 accord ex f22b1 engine am i supposed to get a p28 or is a p72 compatible sry i jus dont kno alot about the computer part but im learning

also if u have a good site i could find one that would b cool

 

ok so i did a little research an i guess the p72 an the p28 will work but can u tell me the diff between them thanks again for your help

 

p28 wont run your IAB's the p72 will run the IAB;s in the intakemanifold.If you do a f23 intaake manifold you will want the p72 if your just running your stock manifold you won't need the p72 and run the p28

 

Will an f23 bolt right on an will that give any more power
