I have a set of 1600cc injectors left over from a B18 Build and I'm looking at possibly boosting my S2K. My question is will they work in an S2K? I'm thinking that they aren't interchangeable but not certain although if they were it would definitely speed up the boosting process.

 

After you change the injector clips on your car they should work but you may need fuel rail spacers

 

Oh ok I knew I could change the clips but I wasn't sure about the fuel rail or intake manifold fitment.

 

they will work fine
all you need is an resistor box and injector clips

 

Like the others said they should work the hardest (if at all) part will be getting the spacing between the fuel rail and intake manifold adjusted for those injectors. Also check how they sit in the OEM injector seals. Maybe if you have different injector seals that you used when they were installed in the B series you can try them out on your s2k as well.

Last but not least you do not have to change the injector clips. If you take out the plastic insert in the oem clips they will slide onto an OBD1 injector.
