is it possible to fit an f18 gearbox to a v6

got one laying around my garage along with a v6

the only thing ive noticed is when i try to mate the two together
the flywheel gets in the way

does this mean that the 2 litre ecotecs have a thinner flywheel(lighter)than the v6

also if thats the case if i swap this configuration(f18+v6)

with the motor thats already in my cally(2liter ecotec) all i would need to do is swap flywheels over

will the v6 except the 2liter flywheel

before you all say why not use the f28 or the f25
the cars for the missis and shes complaining about the heaviness of the v6 clutch in my other car(V6 CALLY)so i thought if i put this in i get my v6 she gets her light clutch

thanks in advance :confused:

Dont know for sure but u can make an f16 fit so why not.
We used a v6 flywheel with 7ish kilos shaved off it. Used a 16 valve friction plate and the v6 pressure plate and chucked in the car.
Anybodys guess at how long the gearbox will last but they are a whole load cheaper than the f28 that will eventually replace it.
:D

It can probably be made to fit but like Paul said it won`t last 2 long. The F18 will only handle 180 lbs of torque (hence the 18) & the standard V6 runs more than this.

If its driven reasonable gently (ie not 2 much wheelspin) it`ll probably last quite a while but your always gonna be leaving it 2 luck.

The F18 is a 4 cylinder box, the F25 is a 3 1/2 cylinder box.

You'll have to move the engine over 40mm, as for the F28 conversion,


V6 is 167 lb/ft 227 Nm so close to the limit of the F18 as mentioned before.

Ian V6 just bought a V6 CDX cav that had a clutch change last year.

The clutch is unbelievably light, lighter than my wife's Ecotec Astra!!

Just change the clutch when you fit the lightened flywheel, and you'll be sorted.
