kaaz lsd mx5 - Drifting forum

taz5430 · 01-04-2008, 00:01

just seen the kaaz 1.5 lsd for the mx5 (1990), just wondered how much power that can handle as ive heard even some after market diffs for the 1.6 mx5 give up @ around 250hp, was gonna weld up but dont know wat to do.

Isn't the problem with the 1.6 diffs the tiny crown wheel, rather than the diff it's self? The 1.8 diff has a bigger diameter gear and is a lot stronger - MX5OC will have details of how to swap to a 1.8 diff. Get the big diff then get a spangly Kazz upgrade.

I'm running a 1.8 diff as a welder in my 1.6.

Yep it's got nothing to do with the LSD unit but the physical size of the diff in the 1.6, 1.8 diff is the stronger unit.

the Kaaz center itself will take as much power as you can throw at it.

Does anybody actually have a Kaaz LSD on their MX5?

They're great - and quite good value too for track use.

Not got one myself, but driven a Kaaz equipped car.

I have the Kaaz 1.5 way (from

) fitted to my 97 1800 and have so far had no problem with it. It just takes a bit of getting used to the noises and the occasional judder pulling out of junctions etc.

A few words of advice though: Don't go to Mazda for your new bearings (I got a pair from a company who just do all sorts of bearings for less than the cost of one from Mazda) and get a new crush washer to make sure there's no excessive play (I didn't know to do this and just live with the occasional clunk, but plan to rebuild with a new washer soon).

If you plan to drive the car on the road I wouldn't recommend welding your diff. My 5 is a daily driver and I think the 1.5 way is about as extreme as I'd like to go for both comfort and cornering ability. I know many people on here live with welded diffs, so it's not impossible, just beware of understeer.

Good luck if you go for it. £500 well spent IMHO.
