Hey guys

I知 after some advice. I have a Ford Fiesta 1.6 zetec se race car mk4/5. I race on a oval track and only using 2nd gear. I have a problem, when I知 coming down the straight I知 running out of revs and losing so much power. I have the ib5 gearbox which I think the 2nd gear ratio is 2.04. Is their any other cluster that would fit into my gearbox but have a longer gearing ie looking at about 2.13 ect.
If someone could list the different gear ratios that痴 would be a direct fit to my fiesta that would be great.

Cheers
