Injectors ?

[Belette]

do you know any injector about 280-300 cc like mustang, dodge or any other ones who will fit into FI honda engine ?

thanx

There are Prelude 310cc (I believe) that should work. I have heard of people using RX-7 injectors... maybe a few others.

I can't recall having heard of anyone using domestic injectors.

A website I have been to says that the obd1 Prelude H22 injectors are like 335 or 345 CC injectors.

As far as how accurate that is...... I'm not sure.

Prelude injectors are 310cc just like accords.
civic/integra are 240cc

If you plan on turboing your car you should get no smaller than 390cc(which will max out rather quickly) I would go for some 450's from DSM if you are on a budget(about $50) or if you plan on getting new ones, they all cost about the same so spring for some 550cc

the 89 4cyclinder rx7 injectors where high impedance and were 460cc njectors. but they are so large you need a standalone to tune them well.

yea prelude injectors are what you want. all 92-2k civic/integra injectors are 240cc (not including JDM) the ecu jsut controls impedance and allows for longer duratino on them when needed. the prelude, vigor, legend, and nsx all use the same injector a well. that's anywhere from a 280-320cc

Mine do just fine.

the 4 what RX-7?


anyways there is a guy on here that a set of 92-96 prelude injectors. he says that they are 345cc. how do i tell? wil i be able to run these daily driven? i have a s-afc and will be buying a obx fpr i guess. i am also buying a walbro 255 high pressure pump. i am going to be spraying a 55 shot but when i go to the track i want to be able to put the 75 jets in.

I read this:

' The FMU is great because it allows the car to run normally on a small injector, but can also increase the rail pressure under boost which, in turn, forces more fuel through the same size orifice. The fuel that the FMU adds has a direct relationship to the boost pressure. The proportionality is usually stated in a ratio, for example 12:1. This means that the FMU will add 12psi of fuel for every psi of boost. (For example, 10psi of boost will add 120psi of fuel pressure.) When all is said and done, this could net a total of about 140psi of fuel pressure which is often too much for a little injector to handle. It is also the reason most people opt for a combination of larger injector and lower ratio of FMU. This is an ideal setup because it allows the same quantity of fuel but at a lower pressure which is more constant for tuning and less fatiguing on the injectors.'


I got only fmu now and I want to stay whit that for a little , I want to know if 265cc injectors will work well if I put static pression little bit lower, and lower ratio FMU like 8:1 (or better ? I want comment on it) ... 265cc is little bit higher than 240 but not that much I think... I'm planning to stay under 7psi of boost...

Does it have big chance to run lean on boost time and too rich when no boost ?


thanx a lot guys ! :)
