carb

man i totally wish it was that easy remember street port is a broad term everyone has different templates some are larger then others . i know that a large street port will run out a 48 to almost the 51 .it's gonna be alot of trial and error. noone can tell you do this and it will be right .not unless they down th e street from you and run the same setup . but check this out http://www.racingbeat.com/FRmazda1.htm and head to the carb section there is a pdf there that might help

This may help a bit, even though the main emphasis is IDAs. A wideband, vacuum gauge and egt gauge will help too.
