so i took my vehicle for a highway run after completing a b16a2 swap and i can get going 165km/h in 4th gear as soon as i hit fifth gear its sooooo slow
Should i upgrade my fuel system to achieve some higher top end speeds?

 

did it fall on its face or just stop pulling

 

it didnt decrease in speed nor increase, i was in vtec range... its a s21 transmission is the gearing in 5th gear that far apart....
