Hi any advice much appreciated I'm just trying to sort the gearbox on my b16a2 engine civic I've got a s80 with m factory 5.1 final drive carbon synchros and a kaaz plated diff with s4c 4th 5th gear this is how I brought the box so since fitting it and trying it I'm a little dissapointed I thought it would keep the revs up high because of the final drive do I need to buy the close ratio gearkit as well any suggestions on ratios or changing just 3rd 4th 5th font need top end speed thanks for any advice

Hi, You will need a short ratio gearset 3rd-5th at least for your needs. Thing with a Final drive is you just reduce the speed of each gear and stack them closer together. The gearset is what you need to reduce the rev drop between each gear.
