Limited Slip Dif compatability

[Pierce]

Hey all,

Forever lurker from Australia with a question.

Can the 1000cc march k11 gearbox (RS5F41A) NISMO 1way limited slip differential fit into the the 1300cc march k11 (RS5F30A) gearbox? I have bought one without thinking or checking compatability.... bloody idiot that I am.

Any info and explanation of options available to me for using the LSD would be greatly appreciated.

the inboard cv splines are smaller pierce, and the diff bearings smaller too i believe

Frank, does that mean it wont fit in a 30A gearbox at all, or that fitting it means installing different diff bearings and custom cv shafts, or 1L standard cv shafts?

Is it possible or should I walk away from the purchase if my only option is to use my 30A gearbox?

Im currently throwing 165Hp with my turbo setup and am tired of single wheel spin.

i doubt if it will fit mate, it should sell ok in the uk tho

 

[Pierce]

Yeah thanks Frank. I figured as much. I'm gonna determine which engine it comes from once it arrives, then resell it to UK market if appropriate. Hopefully it wasn't built for a one of a kind NISMO box or some nonsense.

it was the viscous diffs that had the oddball casing eh, iirc the nismo one is a direct fit to the stock casing

I use a Gripper 1.5way LSD made in Coventry UK with 1-sided clutch pack to fit the speedo gear and double stacked preload rings to withstand 162hp/151ftlb on trackdays.
