- Our cars already have an oil cooler built in, and I haven't seen a good aftermarket one--I also don't know if one is needed.
- Why mess with aftermarket injectors? The stock one's hold up fine on a 6psi setup.
- Since you only mentioned a 'fuel gauge,' I'll go ahead and recommend both an Air/Fuel Ratio Gauge, as well as a Fuel Pressure gauge. A/F is recommended to quickly pinpoint fuel problems, while a FP gauge is extremely helpful for tuning the Fuel Pressure Regulator included with the kit.
- From what I've gathered here, a lower thermostat won't really do you much good unless it's coupled with a lower thermoswitch. So far, there are no aftermarket thermoswitches that fit our cars. What's the point of passing coolant through the engine and through the radiator if no air is passing over it? Read here:

- What other mods do you have? If it's all stock, throw an aftermarket short ram on there...it's good for at least 10whp for ~$100.
Get a good look through my JRSC site in my signature. It's not great, but it helps.
