are my rpm's normal?

[smitty41393]

hey guys, i just got my first 240 (sohc) and its doing 3000 rpms in 5th gear to do 70 on the highway. is this normal? if not anything i could do to take care of that? it has the stock s13 rims so i dont think its cuz of super small wheels or anything.

mine is about the same i have vlsd from a 300xz which is the same ratio as a 240and i do 75 at 3000rpms
my brother however has a s14 wit a j30 axle and he does about 85 at 3000rps
i want a j30 axle for better gas millage i hope

yea thats normal, speed limits 65 so your rpms should be around 2700-2800, i dont like traveling fast in our cars the rpms are like 4000 at 85 and that doesnt look to good for the engine, considering you were traveling that like an hour or so, plus it gets my tappets ticking after that.
