so i posted this question on another forum a couple days ago and figured id post it here too. as my project thread eventually im doing a manual swap but atm its not high on my list. my route to work has me sitting at 3k rpm for quite a leg of my trip so besides my mods and no tune to allow the ecu to properly adjust im only doing about 30mpg. btw I'm only assuming 3k plus mods and no tune is probably my cause of lower mpg. so 5spd civic 70-80 mph can a couple people post me thier general rpm ranges. im aware 30mpg really isnt that bad and its far from seriously bothering me but if a 5spd swap can drop my rpms enough ontop of being able to choose gears gets me alot better mpg. im also aware you dont modify vehicles and still be concerned with mpg lol. it will however give me a 1 up when i find a donar car for the swap and ask the boss if i can buy it
