jdm 5th gear conversion
jdm 5th gear conversion
i have evo8 5 speed tranny with evo 9 1rst gear. i am planning to put the jdm 5th gear ratio(0.825/ 162mph@8000) instead of my long ratio(0.72/ 186mph@8000).
i dont dd my evo; usually friendly drags rolling till 5th gear. i am thinking it would be an advantage in keeping the car in the power band since rpm wont drop alot. however i am not planning to pay for 4.11 final drive at this time.
anyone did the conversion? is it worth?
thanks

i was thinking of the pros i will get from the conversion especially if we take into consideration that i will not go over 150mph in any friendly drag.
shifting now on (0.72 ratio) from 4th to 5th and rpm drops from 7900-8000 to 5500-5600, with the jdm ratio i guess rpm will drop to 6300-6400 and this will keep me in power band.
but still would like to hear other feedback.

yes its definitely worth it. Easier to get into 5th/faster shifting from 4th, the top end is shorter but if its for a road course its perfect, also benificial if for a DD and your speed limit is 55 or 60, you have less engine load a bit better mpg(of course, the 9 5th gets good mpg at 72ish.) As for top end, no need/dangerous on street anyways, and there aren't a whole ton of road courses you'll get that fast on without over 400 hp
lol its too short for a dd car sits at to many rpm at 100k (65miles)? Its the sole reason i sold my evo 6 was wasting gas and driving at 110kph would spool the turbo and just dump gas, driving at 90 with out spooling would save lots of gas tho
