jbaa02 Posted September 5, 2006 Report Share Posted September 5, 2006 Is it possible to change my gear ratio from 4:1 to 3.7:1 without changing my differential? If so, how? Thanks a lot. Link to comment Share on other sites More sharing options...
Medicine_Man Posted September 5, 2006 Report Share Posted September 5, 2006 You have to change the ring gear and pinion on the diff centre. Depends what diff it is and if the ratios are available really.. Link to comment Share on other sites More sharing options...
irokin Posted September 5, 2006 Report Share Posted September 5, 2006 Youre talking about the final drive ratio...which IS the differential. Unless you want to shell out upwards of $4000 to have your gearbox re-ratioed (which would be really stupid) you're gonna have to play with the diff. What car are we talking about?

JDM_GUY Posted December 13, 2007 Report Share Posted December 13, 2007 I have a 1981 corolla liftback in the philippines,it is fitted with a limited slip differential and a W50 tranny which I plan to change back to a T50. Wow, why would the heck would you wanna chance the w50 to t50? It is better tranny due to durability for high HP. How much would you want for the W bell housing by the way if you happen to change the tranny? Link to comment Share on other sites More sharing options...
