Hi, im in the uk so there are limited oarts available here for turbo cars. i have a crx vtec (B16a1) and have turbo, intercooler ect sorted. all i need is some injectors. i carnt afford new one so i am looking at second hand. what sort do i need so i dont have to have resister blocks or inline resisters?

Actually, a set of 440cc injectors will do just fine for a b16a1, and you won't need a resistor box.

Check into some dsm 450cc injectors.. You can get a set of them for $50-$75 anywhere..

really that easy? some bloke on the uk forum said i would have to put resisters on just about any injectors unless i bought new RC one designed for honda. ive found some dsm 450cc low impedence peak and hold and you say these will work fine with no other mods?

Well you need to run a resistor box since they are low-imp but thats very easy to setup..

Right ok, how do i go about building one?
Im good a that sort of thing as im an engineer but im not sure what it involves. Is it easier to put theresisters inline with each injector?

I think you car came with resistor box. You might want to check first before you buy the injectors. If your car came with factory resistor box, then you can put the dsm 450 in. You might have a hard time trying to get it idle right. I could be wrong on this.

am i right in thinking that the box mounted on the side of the inner wing is the resister box? its got maybe three wires going to it and caution HOT writen on it

Inner wing???? We are talking about a car and not an airplane right..LOL

That might be it.. Count the number of wires going to it.. If there are 5 wires then thats it..

Ha ha sorry thats the different terms like we call hoods a bonnet, fenders are wings and trunks are boots. it is a car!
Im pretty sure i have the resister box so i think i will get some dsm's

Just test the stock injectors that you have with an Ohm-meter. If they are like 2-4 Ohms, they are low impedance [means you have a resistor box already] and you will need to either buy more low impedance injectors or remove the resistor box [it's easier just to go with low impedance injectors]. If the injectors read 12-14 Ohms on the Ohm-meter, they are high impeance, meaning your car doesn't have a resistor box, and you'd either need to find some high impedance injectors or wire in a resistor box to use low impedance ones.

Ive bought some 390cc injjectors and they come with a resister box so i should have no problems now. i hope. I have an old style afc with the single **** on the front to richen or lean off the mixture can i use this in the same way as the new S-AFC' (AFC Hack) or do i need to up grade?
