as my 1jz swap is still new to me, i have noticed that my mpg are not that good, granted i am not pa pa driving it yet, still heavy footed due to the newness of the power.
my stock set up out of the bmw was a 5 speed , 5th gear was 1:1 no overdrive, and rear diff was 323s. and doing 60 mph i would turn about 3krpm. the bimmer motor loved it and got about 25mpg hwy
the 1j swap has a r154 and i swapped out the bmw diff for a 410lsd , in 5th gear witch is overdriven i think .74 :1 . the motor is almost the same. 3k to do 60 mph+-100rpm
so i guess i am wondering what a stock supra is turning at 60 and what kind of mpg should io expect.?
i love the way the car handles with the 410 rear diff lots of fun and power in the taller gears, but should i possible look into 373s?.. bmw also makes a 391 but its a larger diff and axles , and driveline, very hard to find and prob out of the question. so 373s is the next closest gear ratio..
my 1st tank of gas i got 9.9 mpg,,lol lots of foot ,mostly in town, and had a very bad rich idle condition. that has since been fixed. but still not seeing much inprovment,
