Cheap methanol injection

5 gallon Sparkletts jug tied to the corner of the bed; drill a hole in the cap, stick a hose through with a grommit.
Buy a pump capable of at least 100 PSI.
Buy a pressure switch. Use the pressure switch to engage the pump.
Use a mister nozzle found in the "Garden Supplies" section of the hardware store.
A check valve is a good idea to keep the water in the line between the nozzle and pump from dribbling down into the engine.
The pressure switch is optional. You could just use a manual switch and not forget to turn it off ever. Or use a momentary contact switch on your accelerator pedal.

I don't know anything about water injection on naturally aspirated engines.
Short of, say, attaching a hydraulic or pressure washer pump to a starter motor or something like that (which is how you get 1000+ PSI with a 12 volt pump), the best 100+ PSI 12 volt pumps that I know of are the ones marketed for water injection that sell for $100-150. They're all Shurflo's, but I went to a Shurflo distributer in town thinking I might be able to get a bit of a discount by cutting out the middle man and they wanted over $200 for the same pump. So I think that the pumps for water injection are priced pretty fairly.

I used a hydraulic pump unit for a lift gate off a medium duty truck. I used water pump lube in the water and I injected after or in the intake air horn. I do not like the idea of water in or before the I/C. I also used the produce cooler nozzle and was running 60+psi of boost. The set up worked awesome.
