Hi , i have EDM Ek4 98 Civic HB B16A2 with S4C no lsd tranny . it has 4.266 final ratio. and 1-3.23 , 2-2.105 , 3-1.458 , 4-1.107 , 5- 0.878 i want to change my final ratio to 4.40 . i want to learn if USDM 99-00 Civic Si 's final dirven gear and counter shaft fits to my tranny ? i think that it will fit but i must know if it is exactly fits. i have installed 1 year ago 4.785 kit from jhpusa. i know that this 4.785 kit fits to 99-00 civic si , so civic si ' s final driven gear and countershaft will fit. Any opinions ?
