Thanks Mark, I am going to start with the Ford 42s. According the calculators they should do the job but if not I will go bigger. Jerry

Jerry,

I don’t recall if your question ever got answered concerning injector sizes.  N/A 13B’s came with 460cc injectors, and the 13B-REW came with 550’s.  I think the high-output Renesis has six injectors, but I haven’t verified that.  The racers typically go much larger.  The only real drawback from using the 550’s in a n/a engine is the idle.  I didn’t notice any real difference between the two sizes.  On the high end, it doesn’t hurt at all (probably helps).

Mark, is your engine a N/A 13B? Do the 550s equate to a little more than 50 lbs/hr? That is hugh. Did you find the 42 lb/hr injectors to be too small? Lastly, can someone tell me the size of the stock Mazda injectors? Thanks, Jerry
