Ok so I am sure most of you have noticed the proliferation of small dimension gear reduction starters avaliable for pretty much any old car. They all seem to be based on the same or similar starter with a cast or machined adapter plate, sometimes very crude ones at that, and have wildly varying prices.

This fiat 850 specific unit for over $350

Looks to be based on the same starter as this jag piece for under a hundred bucks.

I like machining projects and don't like spending money. I would like to attempt this myself. My question is.....What is the original source for these starters. I am guessing they are off something rather pedestrian or overlooked. Much like the $99 John Deere gator alternator is sold by race car and hot rod suppliers for up to $250. I would like to find one of these starters used or rebuilt so I can get started.

They appear to be japanese in origin but do not look like the honda types I have found. Any ideas?

I posted this on the prod car forum awhile back, got some good answers / sources.

Looks like a NipponDenso starter. I'd look at various Toyotas. They have several different nose lengths, so it should be pretty easy to find one that has enough room to make an adapter.

Something like this: You could make an adapter block and bolt it to the starter ears and put the new mount holes where ever you want. The block's thickness will determine how far it goes in to mesh with the flywheel.

Excellent info. As long as the rotation direction is correct then it is just a matter of ensuring the gear will work and if not replace it.

Hmmm.. Rockauto even lists the direction

1995 Corolla is Clockwise rotation! Now to find a used unit. and experiment.

Yea, they are Nipondenso starter motors. There's about a half dozen of them, at the most, and the difference is the clocking.

My LT1 has one. In fact, they're OEM. Cost is about $200.00 an an incredibly common car. Just sayin'.

Turns out I need Counter clockwise rotation. I just held one in my hand (95 civic) and while the size is perfect the direction was not. Looked reasonable easy to adapt as well.

Just get one from just about anything that's not a Honda. Honda 4cyl engines are backwards from the rest of the world.

Side note: We had a guy bring his car into our shop (at work) to have an engine installed, a late '90s Accord V6. He said it jumped time, and had no compression in a few cyls. We installed a known running engine in it, and it wouldn't start. Same exact symptoms as before. It took us many days to figure out what happened. He had bought a starter from Autozone, and they gave him one for a 4cyl by mistake. He thought that after he put it on, the car must have jumped time. Nope, it was just turning the wrong direction.

I'm gonna bump this one back up because I just spent 3 hours on rockauto looking over every manufacturer I could think of and didn't find what I was looking for.

Small japanese gear reduction starter, CCW rotation and if at all possible a 9 tooth gear.

The best piece of information I have found on the web all week.

Subaru Legacy! The starter itself looks identical to the ones that Fiat suppliers are selling with adapters.

VOLT 12; ROT CCW; TEETH 9; KW 1.0

Stronger, smaller and lighter than the OE Fiat piece. Now to head to the junkyard so I can get started

Just wanted to give a little advise to any who may want to embark on this path.

Since I have been buying Denso starters for about 17 years now, I'll tell you one drawback to doing it yourself. For any given model of Toyota honda etc, there are at least 3 starters, auto, manual, cold weather, california blah blah. Then there is denso and mitsuba. On top of that, the rebuild houses figure out what lester number[that 16xxx or 17xxx number] across years and sometimes models will work, and will sub those numbers for others if they are easier[or cheaper] to source.

Why do you care? Well, you don't. Unless when you go to trade that autozone unit in and all they have are mitsuba, or 1.2kW instead of the 1.4kW or donut back instead of silver body. Oh, and on top of that there are several different nose [drive end]castings for each unit, so if you buy the wrong one, it may have big holes when you go to machine it where it didn't when your friend did. Trust me, I have found this all out the hard way.

Now my company does not make the fiat unit pictured, and the reason is the size of the nose is so small it is difficult to use my method of manufacture[IOW machining an existing drive end housing rather than casting one] so you would have to use an extremely long neck starter[like the Camry starter in one pic] and a very hefty piece of aluminum to back it back out again. Expensive and time consuming. Hell I own a machine shop and pallets full of starters and I would buy that if I owned an 850!

Please don't get me wrong, racers taught us how to do this conversion over 20 years ago, but most of them buy their starters done now, because they have other things to do with their time, and there are several companies making conversion starters [mine included]

Can it be a fun project if you have access to machine tools and some stock? Sure. Is it 'cheap' or 'easy'?

uhhhhhhh.....that would be up to you.

Last warning. Putting unmodified starters in your car [starter from car x 'bolts right in'] is usually not the primo answer. Starters are designed to be located by the locating boss, not the bolt holes. Japanese starters never use the same size locating boss as Jag or Triumph etc. Either making or purchasing a custom starter allows you to machine the proper locating boss, and also clock the starter to the spot you want it so you do not have to take a hammer to the sheetmetal.

So, if you made it through this post, here is some somewhat useful information

Toyota Camry and boxer Subaru both use CCW starters. most all other Japanese starters are CW. parts are NOT compatible between ccw and cw so buy the right one to start.

Pick as late model a starter as you can, learn the Lester number, check that you are getting the proper unit for the lester number you want, there are non retail sources on the web that will show you true images for the units, rather than a generic starter picture.

If a starter is painted black all over, pass. Major reman houses always replate hardware and will only paint what was painted originally

Whatever path you choose, good luck with it.

Been a while. I bought a scooby starter from the pick-n-pull on june 20th and right off i found that the 9 tooth gear on it was twice the size of the fiat 9 tooth gear. I spoke with a fe machine shops about resplining options and none were really doable so I annealed the two gears and hit the lathe. I cut the teeth off the scoobaru gear leaving just a splined tube and then bored out the fiat gear so I could press the afformentioned tube into it. With the TIG on low I laid the smallest weld beads I have ever done using .023 mig wire as my filler on both ends and then heated and oil quenched the new "super gear" to re-harden it. A file confirms that it is indeed hard. Too hard? I don't know that one. If/when it fails I can always push start the bugger. It is not like I take this car on long trips or anything.

For the adapter I just took the nose of a fiat starter and machined it down to fit centered over the denso's nose making sure it was holding the gear in the right location and welded it on. Welding 40 year old greasy engine bay cast aluminum sucks.

I figure I will bolt it to a spare motor and trans this weekend and give it a few dozens cycles to see how it holds up.
