172 cup and non cup differences?

[james alford]

Is there a list of all changes that were made between the 172 cup and a non cup edition?
I want to know which parts are interchangeable so i can get some spares for my race car.
Thanks.

What about mechanically, like engine, gearbox, driveshafts, hubs, brakes etc?

Different driveshafts
Different wishbones

 

[icebergclio]

gearbox is different i believe due to lack of abs sensors so uses a speedo drive.
engine is the same
brakes are the same minus abs rings

Danny, do you know if there are differences in the engines/bolt ons around the engine? I know that the alternator setup is different but not sure what else is

 

[icebergclio]

alternator set up is only different on the aircon delete model otherwise theyre the same. removing the aircon frees up A LOT of space in the bay

 

[DannyR]

As above.

 

[james alford]

Okay cool. I guess the only other thing I need to check is whether there were any changes engine wise between them

 

[icebergclio]

engines are the same dude

There was a rumour that the cups had engines cherry picked off the production line, but this was most probably b****cks

^there was also a rumour that cups had different mapping from a standard 172, but as you say..... lol

 

[james alford]

Thats not a problem, i have ITBs and a ktec ecu so its the main engine and other components that i need spares of.

 

[DannyR]

I've got an engine if you need one?

Different driveshafts
Different wishbones

Any ideas what is different with the cup shafts/why they are different to non Cup?
