406 Clutch and Gearbox

[Pob]

Hi all,

Is there any difference between a Turbo and a 2.0 gearbox? I was wondering what difference's if any between the two regarding clutch plate/flywheel diameter.

Many Thanks,
Dan

yes a 2.0 gearbox is much larger than a turbo.

sorry ive been drinking

Gear ratios. Each box is geared to match the engine output, put the wrong box on and you'll kill the performance

[alladdin]

ratios between petrol engines should be broadly similar. a turbo engine will produce much more tourque tho so might well be beefed up and have a larger stronger clutch. also since the diff is included with the box you have the overall gear ratio to consider. a 3.0 turbo will normally have a taller ratio than a 1.8

ratios between petrol engines should be broadly similar

The 2.0 turbo is a low revver so the gears will be far too long for the non-turbo petrol 2.0

Does the 2.0 gearbox/engine use the same size clutch plate and flywheel as a 2.0 turbo? The reason I'm asking is that I'm putting a turbo engine in a 205, people use a Mi flywheel and clutch so it fits a 205 gearbox. I was thinking of using a 406 gearbox so I can use the standard size clutch rather than a smaller Mi one as they tend to give up after a while. As I carn't use a turbo gearbox as its hydraulic, a 2.0 gearbox is cable so it should work.

you will probably find they are similar. the taller gearing is due to the diff ratio.
are the ratios in a haynes these days ? i doubt it.

as for clutch , look at the diameters, bigger is better. i have no idea which bits mix /match tho.
