1.0 ratios vs 1.4 (road rally car)

[Welsh_Monty]

evening all
I'm back with another micra, but this time shes a 1400cc,
anyways I'm building up a well spec'd road rally car (again) but id like some advice on the gearbox ratios, ive always seen people change the 1.3 box for a 1.0, but in reality is this going to make a difference?
any advice would be great
thanks all

I used to run the 1ltr gear box best inprovment that you can do on budget.

bear in mind there are many different types of 1.0 box

I've got two 1.4s 2001 models. One with the 1 litre gbox and flywheel, and one with standard 1.4 gubbins. The difference is quite vast. The 1l gbox one is really nippy and fun. It does 50 miles less on a tank. Best conversion I ever did.

I also have a facelift 1.4 with a 1.0 gearbox after the 1.4 gearbox developed a problem.

It transformed the car which was already nippy, and responsive with an Almera air box and solid engine mounts, in the first place. The revs are a bit higher which is noticeable at 70mph, but the rewards outweigh the noise.

I still have the 1.4 flywheel so the lighter 1.0 flywheel would be even more zippy.
