edwardm Posted December 2, 2010 Share Posted December 2, 2010 Is it possible to run B16 gearboxes on our cars?Don't massively want to part with £600 odd for an S80... so what about gearboxes like Y21's from the EK4?Most don't have an LSD i don't think?.Cheers Link to comment Share on other sites More sharing options...
civicturbo79 Posted December 2, 2010 Share Posted December 2, 2010 Any B series gearbox will fit onto the b18c4 engine , But the s9b and the s80 are lsd all the other are not . Rich. Link to comment Share on other sites More sharing options...
edwardm Posted December 2, 2010 Author Share Posted December 2, 2010 Ok,Has anyone tried running a gearbox on the MB6 OTHER than the s9b or s80?Any decent results?Cheers Link to comment Share on other sites More sharing options...
johngreen537 Posted December 2, 2010 Share Posted December 2, 2010 There's someone on here who runs a Y21 mate. Have a search for Y21 Link to comment Share on other sites More sharing options...
edwardm Posted December 2, 2010 Author Share Posted December 2, 2010 Rite, after searching it would seem the S80, S4C and Y21 boxes are the same ratio as the S9B in first gear, am i right?So what makes the accel. better? Is it the difference in final drive?Or is it only second and third gears that are better? Leaving the slow first gear to remain regardless of what gearbox you have?Cheers Link to comment Share on other sites More sharing options...
nova2fit4u Posted December 3, 2010 Share Posted December 3, 2010 With the s80 your vtec wont drop out while changing gear ...s9b does and s80 got more torque through the 2nd n 3rd gear...from what i heard you will lose the top end speed though Link to comment Share on other sites More sharing options...
johngreen537 Posted December 3, 2010 Share Posted December 3, 2010 Yeah mate, final drive mainly. S9C has higher ratio in 2nd too. But it's the FD that gives the improvement! Link to comment Share on other sites More sharing options...

johngreen537 Posted December 3, 2010 Share Posted December 3, 2010 THat's the other option Get the Diff and FD (1 unit i think) S4C from an EK9 and use that. Much more money labour costs though! Link to comment Share on other sites More sharing options...
