hi, just wondering if anyone knows the gearbox codes for a 6 speed uk and jdm with a 3.9 front and rear diff?

Fat Boy

JDM have all got 3.9 F & R - TY856WB***.

UK TY856WN*** have 1.1:1 transfer gears so have different F& R diffs

thanks fatboy, im building a 6 speed box up for 1/4mile, i've been told to use 3.9 front and rear diffs with 1-1 drop links with a uk box for the taller gears so im not going over the line in 6th! someone thrown a spanner in the works and said i could use 1st and 2nd from a jdm to get off the line quicker and 3/4/5/6/ from a uk with the taller gears. does that soung right?

JDM and UK are the same 1-4, only 5-6 are longer on the UK box.
