My 1997 Prelude SH does about 3.7k RPM at 74 mph (120 kmh) on the highway and I was wondering if other 5th gen owners were getting the same thing because at 3.7k RPM, my gas tank gets empty pretty fast. I bought it used, so I dont know if anything was changed. Any ideas?

 

that would be normal for the 5th gens

~3k @ 60
~3.5k @ 70
~4k @ 80

At first I also thought that would eat gas way too quickly, but suprisingly after a 300 mile trip at ~75mph, I ended up a little over 31mpg

That's normal. You should be getting about 26mpg on the highway, atleast.

 

Thats good to hear. I was telling people that I was getting 3.7k and they were pretty surprised, but they dont know much about cars. Its just fun to see their reaction when I tell em every time

 

random question, but would I be able to find a 6 spd tranny that would fit the h22 or can I add on a 6th gear? or am I just dilusional and stop dreaming in my fantasy world

dilusional, u can either change the final drive gear or get larger diameter tires if you want to lower the rpms for any given speed

 

pretty sure accord 5th gear will fit h22 tranny and lower your highway cruising rpms. i personally wouldnt do it ou still get good gas mileage and have some torque on tap with the rpms that high
