KAAZ Limited Slip Differential Compatibility
I'm seriously considering a KAAZ LSD, on an NCP93L, 2007 Canadian sedan 1.5 L 1NZ-FE.
Couldn't find anything with the search function. Nothing sedan-specific. Makes sense, since I assume most of you are hatch owners. Apparently one thread even mentioned an install on a Scion, but nothing for a sedan... Has anyone had this installed on a sedan? Fairly straightforward? Any machining required? I'm probably not doing the installation myself, but the less headaches for whoever has to do this work, the more likely s/he is to do it right. cali yaris, is this product compatibility something I should discuss with you? |

NCP91 and NCP93 are identical drive-train wise, so the KAAZ for the NCP91 will work without issue.

Noted, and tempted even worse! If only I can find someone reliable enough to install it right.. Installing this is beyond my resources and abilities for now.

Just to verify as well - You do have a manual transmission? The LSDs are only for MT Yaris.

I would start by looking around at transmission-only shops, or even performance tuning shops. Find out if anyone on their crew has worked specifically with installing LSDs and understands how to set pre-loads. I'm elbows deep in my LSD install right now, and without a full machine shop and automotive bay to work in, I wouldn't even attempt it.
Unless you can afford to have your car in the shop for a week or two (some parts will have to be ordered mid-build), I would suggest buying a used gearbox and using that as a donor. That way if there are any issues with worn synchros, bad bearings, missing teeth, etc. there is plenty of time to get them sorted out while you're still on the road. Once the donor gearbox is sorted out, a quick(?) R&R is all you'd need to get it installed. Keep in mind that the cost of installing it this way will be significantly more than the cost of the differential. |

Thanks for the massive, jagged pill of reality, Crank. Perhaps I should enjoy my sedan while it's still tame and economical, and then save up for triple my budget on performance parts.
Out of curiosity, what do you mean by setting preloads, on transmission? |

I sent mine out and it came back with the LSD installed, ready to plug in with a new clutch.

The tapered roller bearings on the differential need to be "squished" a little bit to keep them from banging around under load. Too tight = premature wear from friction, too loose = premature wear from rattling/impacting. You check the preload by rotating the differential and measuring the torque required to start it moving. For an open diff, you can use a fork-like extension to grab the spider pinion. For almost all LSDs, you need to either have a chopped off drive shaft or install the pinion shaft with the diff and measure the torque on it. I'll see if I can find a few DIY threads with better explanations/pics of the process. |
