Hi guys, I just wanted to find out what difference I’m going to see after ditching the v160 and Ao2B for now my current v161 with a Bo3B. I know with cars like these we shouldn’t worry about fuel but mine wasn’t the best on the motorway and people say with the new diff it will be better, is this true and will I get a longer gearing with my new set up

 

Many thanks guys

Or just put new sensors on.

Also, surely the cost of changing your diff and gearbox wouldn’t be worth it for the tiny difference in mpg?

 

The reason I say clean them before replacing them is would suck to spend a couple hundred quid and find it makes zero difference :)

Before blaming it on the gearbox/diff ratio have you worked out what the actual MPG was or is?

 

Id then be looking at the state of the 02 sensors and cleaning them with lemon juice and working out the MPG again.

 

Hey dude they was brand new when I went single

No and I haven’t swap them for that I was just asking if it would make a difference as I was told it would

It will be better, because you have the right diff ratio for the 6 speed. However it will never be good because it’s a 3 litre with a huge turbo and injectors?!

 

The 1st part is what I wanted to know and the second part, I know fuel would be bad and I’m not complaining I was just told it would improve so just wondering if that was true ?
