can you use 2 differant inpedance injector or would it just be better to get a two of 2 lower inpeddance one to match i have a pfc do that make any differance ?

 

mixing them and using resistors on low imp injectors is done every day. Not saying it is the best solution, but it will work.

this link will help you select resistors: http://injector-rehab.com/kbse/resistor.htm

 

i have a set of (part number)#051600PI 1680cc Marren Performance i have no idea what size resister to get or u sorry for being such a noob

 

take an ohm meter and measure the resistance of the injector. if they are 5.1 ohm (same as bosch) use 3 ohm resistors. if they are 2 ohm go with 6 ohm resistors and if its something different just do the math difference to get you around 8 ohms per.

 

if you click the link I provided, it would tell you.

read this, howard coleman says you can get an aditional 15% fuel if you do it the right way.

anything howard says i listen : )

 

How many people really need 15% more fuel when running 1680cc injectors? Thats alot of power if you max them out even with the resistors.. You can also get more fuel by rewiring the fuel pump or raising the fuel pressure.
