Hey Dudes.
I have a mk3 Supra with a w58 gearbox. In 5th gear at 110 kph I'm doing 3200 rpm. I have no idea why Toyota would make a GT car with such petrol guzzling rpm's at cruising speed. Anyway, I want to drop the revs down to around 2500 rpm. Any ideas on if this can be done, correct ratios and availability of gearing?
