Default 5 Speed to 6 Speed

I was just wondering if I would be able to fit the 2.5L engine's 6 speed gearbox to my 2L petrol car.

As having the 5 gears it revs quiet high at motorway speed, so being able to upgrade if possible would be great.

Any help is appreciated

Thanks,

Adam

it may do if both engines are the same type but the gearing will ruin the car it will make it lifeless and thirsty , it will feel like it has a 1500 cc engine in it . There is nothing wrong with doing those higher rpm at 70 mph , always plenty of power on tap , I assume now it is the ford/mazda 2.0 4 cylinder ...??

For reference at 70MPH my 2.0i is doing 3,050RPM, my Dad's car with 6 gears (also a 2.0i engine - Mazda CX-5) will do it at 2,500RPM.

I've driven a Vauxhaull Mokka (eurgh) which was pulling over 4K RPM at 70MPH so 3K RPM doesn't seem that bad to me!

volvo chose the gearing to suit mpg /emissions / power available . I daresay the ford focus with this engine has similar gearing , remember the main power from this engine comes from 5000 to 7000 rpm so it's quite comfortable at 70 at 3000+ rpm . Fuel consumption is not necessarily related to higher rpm . I have an engine which does 5000 rpm at 70 and does 50 mpg and 100 mph .
