What size jet for a 1.8l Mazda Miata with M45 supercharger

[soflarick]

I have a Jackson Racing M45 supercharger on my 1996 Miata 1.8l engine. I am going to purchase a 2d kit and would like to know what size water nozzle I should start with. Thank you.

Does the kit contains an intercooler?

Assuming you are use 300cc/min injectors and no intercoolers, total of 1200cc/min. A 0.6mm/0.7mm jet will be a good starting point.

Thanks for the info. I did a search after posting and saw that .5 to .7 is a good starting point. The injectors are factory 1999 1.8, so I think they're 230cc or 250cc. No intercooler.
