Nope, when I had 1.8 HGT long time age I was frustrated with fuel consumption because the 5 gears were short ratio and screaming at 70mph, I was thought of fit six speed gear at that time I did not find any other Fiat spec six gearbox would fit to this. I went for 1.9 HGT because of the long gear ratio, 70MPH at 2,100 rpm.
