later 4 spray injectors?

[exup]

Believe theres a mod to put later 4 spray injectors (poss m3 ?) on to a m20 , 320 in my case , its mean to give better pick up / mpg ???? would you need to change the fuel reg to a 325 one to get it to work ??
does it work ????

Waste if time. There are better ways to spend your money like 6 branch, remap, proper induction kit.
