Displacement x RPMmax /2 = CFPM (make sure you get the CC/Cubic Inches right) then calculate the fuel needed for that air flow rate to obtain the fuel flow rate at the air/fuel mixture ratio. Or figure the rate you could burn fuel at at max speed with maybe 45mpg at 90mph = 2 gph then convert the units to cc/minute.

Okay, great help from https://www.docinjector.com/

Not much on their site or their eBay store, but I emailed them and they responded really quickly.

Apparently the injector size is a huge 400 cc/min (39 lb/hr)! I guess it makes sense considering that it is one injector feeding three cylinders = 133.33 cc/min/cylinder (13 lb/hr/cyl).

Oh Yeah it is a throttle body injector in the Geo - maybe a turbonator would work and acetone too!

I guess to figure out the CC of gasoline you need the weight or volume of air to gas ratio I guess it is by weight 14 to 1 ratio?

So are you going to shift to the GM Sychromesh fluid? I can somewhat relate to the question about using gear oil in the Swift. If Honda has me putting in engine oil, I would think the Swift would definitely need a similar viscosity.

Actually I'm considering 0W20 since the winters are so cold around here. krousdb doesn't seem to be having any trouble with it in his Honda's and I'm running a Japanese drivetrain as well...
