Nitrous Systems?

I've read the FI sticky and read the info about Nitrous systems. I'm just having a hard time finding a suitable system. I have a 2003 Ford Focus SVT, that has had alot of N/A work on it. It is not my DD and will only be a summer/strip car, it's gutted as well. I know it will have to be tuned for FI if I use a big shot, I have a N/A tune by Tom ofc and will update down the road for FI. But my question what would be a good choice for a 03 SVT? I want a wide range of sizes and Zex seems to only have one kit that varys from 50-300. Anyone able to help it would be appericate I've looked on Summit and google a little.

CM Stage 3+,HawkPS , EBC Rotors, Torsen LSD, Tom's Tune, VF Mount, FRSTS, MSD Coilpack, Massive Wires, Massive Strut Tower, TSM, CF70mmTB, and Cat Cam.

Make sure you get colder plugs.

You should be able to use just about any wet kit out there. Do you want direct port or a single nozzle?

With a single nozzle system, if you spray into the TB you're probably going to have TPS issue. You could make a TB adapter plate, screw the nozzle into that, then put the TB on top. This would save you the TPS issues.

With direct port, you'll have to drill your intake manifold for the nozzles - one per port.

The rest is all in the tuning.

NOS makes a kit that goes in under the injectors and sprays the fuel and NOS and is adjustable
