These infos complicate more that clarify the problem. !
Anyway if you want to make a car for accelaration then a CR 3.94 is better .
For me the sweet spot is to have with 5th Gear 300RPMS 100Kph .
If you have a C20XE a Longer gearbox will help crusing.
Many years ago i had an excel with all Opel gearboxes and final ratios so to simulate ( with specific tyres) the speed with different boxes .

Practically can anyone say how this would work out on the road(assuming correct tyres fitted): mk1GTE with CR vs 2.016vGTE (with whatever gearbox it has).

For the standard 2.016vGTE the roadspeeds are approx:

2nd Gear : 20mph = 2000rpm
3rd Gear : 50mph = 2900rpm
4th Gear : ???????

Thanks for the info. The only thing from memory the mk1s GTE's with the CR gearbox had brutal acceleration. I can't remember what rev range I was drivng in.
