Final Drive Gear Ratio For 1.8, 2.0, 2.5, 3.0 And 3.2 Engines

Recommended Posts

Just exploring a bit of after market fiddly diddly....

 

What are the ratios or the number of teeth of the final drive for all the 147/156/GT varieties?

 

1.8

2.0

2.5

3.0

3.2

 

I'm thinking of replacing the 3.2 V6 Final drive with something a bit shorter for quicker throttle response. Since I'm not going after more power, but better delivery of that power in its rpm range, the final drive is the simplest modification to get that.

 

Yes, higher fuel consumption and lower top speed will be the limitations, but I don't travel at 270kmh regularly so its something I can live with.

 

Cheers guys!

OK forget the 1.8 and 2.0, completely wrong cogs from a completely different gearbox, and to replace the fnail drive in the V6 box you need to replace both shafts.

Thanks Smaky, so if I can get my hands on a 2.5 or 3.0 Final Drive, I can swap it over to my 3.2 gear box.

Any idea what the ratio is?

You'd need to swap out the input and layshafts,

 

Final Ratio - for 6 speed boxes only!

 

2.5 V6 = 3.937

 

3.2 V6 = 3.733

Thanks. Good news for me then.

 

How about the 2.0 JTS selespeed.

Which gearbox has the next lower set of gears that can do a similar swap?
