Almost 3 years later i'm back with a 1999 OPEL Corsa 1.0 12V with 54 HP.

First i gave it a full service. New brakes, new airflow meter, O2 Sensor, air filter, sparkplugs, oil (0W40) with filter, carburant filter, added ceramic additive in gearbox and motor, cleaned EGR valve, installed rpm meter etc...

Currently it's running on 145/80 R13 tires inflated to max sidewall. Last week i swapped the gearbox as the ratio of the original one was too short. With the new gearbox i've lowered the range at 100 km/h from 3446 1/min to 2772 1/min. The 4th gear is now as long as the former 5th gear.

Original diff gearing was 3,94, 5th gear 0,892
Now it is diff 3,74, 5th gear 0,761
So the rpm level in 5th gear is 19,56% lower.

I've ordered a MPGuino, too.

This week i will install a full grille block. I will wrap the original upper and lower grille in car wrapping foil and get them re-installed.

I'm still doing the first fuel tank. It's got a 46 ltr (12,15 Gal) tank and i hope to do more than 1000 kms first. The "EPA rating" in ltr/100km is
Urban: 7,6 (30,95 US MPG)
Highway: 4,8 (49,00 US MPG)
Mixed: 5,8 (40,55 US MPG)
To do at least 1000 kms I’ll have to reach 51,13 US MPG or 4,6 ltr/100km.
