Speedo - Help!

[Corolla_XLI]

I've just bought some indiglo gauges for an american rolla :D .

Here is the link :

But the bad thing is they only make speedos that go up to 110mph :ffs: . I've got a pulse driven speedo on my E10 (it says E37 on the bottom of my speedo gauge).

UK 'rollas display 140mph max. So, I was wondering, is there any chance of calibrating my speedo to go up to 110mph so that it will give the correct reading with the new gauge?

My first thought was to buy a pulse driven speedo that only goes up to 110mph.

Thanks for any help.
