1.8t gearbox ratios ??

Hi I've just bought a mk1 that's had a 1.8t conversion carried out I'm told it's running a gearbox from a 2 ltr mk4 golf but the ratios are sooo low compared to a mk4 Gti 1.8t that I've owned.

Does anyone know what ratios the different boxes have

Any help would be great

PM me your e-mail address, I have an .xls of vw box ratios that i'll send you.
