Default Lightweight Starters?

Is anyone running a smaller starter and did it save you any weight? I've found some Ford Racing mini starters for small blocks that weigh 5lbs. I don't know how much the factory Miata one weighs but it looks huge and I'd guess it has to weigh a lot more than 5lbs.

If you want to install a lighter starter motor but don't want to lose one of the three mounting holes, the 1994-97 automatic is an option.

1990-97 5-speed (and 1990-93 auto): 9.80 lbs
1994-97 automatic: 7.05 lbs
1999-05: 6.00 lbs
I swapped to the newer starter when I did a 6 speed swap and it's noticeably smaller. You can run the 99-05 starter on an older 5 speed but only 2 out of the 3 bolts will line up (it'll be fine).

Probably not the lightest solution, but a good start.

Thanks for the info and I'm a fan of factory parts that are lighter and reliable.
