Civic ek4 vti
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
