I have a 92 Miata 1.6L with the following
1. Racing Beat Exhaust and headers
2. Jackson Racing Super charger, with big boost kit..running 7-9lbs boost
3. I have the timing control, whereby I can tune timing from inside car.

I am getting ready to add a BR performance od pully to my superCharger which will put me at 10-14lbs of boost. All of the items I have installed myself thus far.

I do not have an intercooler, so my main reason for WI is protection, however I have heard of nice whp gains as well.

My question is this. I have seen many do it yourself kits. some seem quite nice and lower costs. What size and mfg of pump should I use to run WI or a mixture of spirits. I probably will buitd the one that utilizes two jets one just as boost come in and another about 8-9 lbs of boost. Any suggestions are more than welcome. tia
