Where did you get it from? I remember a guy saying he got a 300rpm starter, and that would make my starting a lot easier, plus the fact that I have had to deflood/crank my engine so much I am afraid one day it will die.

 

I'm pretty sure all RX7s, or all cars for that matter, have a ~300rpm starter.

 

i think i saw a post with someone saying they got the car to crank 300rpm's by replacing all the cables and cleaning all electrical connections.

 

300 RPM Starter? Where did you see that?

As for who makes it or how he got it, I would have to say that he probably dicked around with the internals to give it a little oomph; like rebuilding alternators with stronger stators and rotors to get more amperage out of them.

I thought ours were like 150-200RPM?

 

No, the 13b's from the 2nd gens spin as fast/faster than ours, and they hit about 225 max.

 

If you can't find one , try running a fatter cable.
I used welder leads (1 gauge, I think) in my F-150, and it spins pretty fast.

 

I don't need to get mine to spin faster, I just may need to get a new starter soon, and wouldn't mind having a high speed.

 

to be honest if your car isnt starting on a normal 1stgen starter you have other problems...

i had my car working perfectly would start instintly on cold mornings

an that was a stock motor with a nikki

tho everything emmisions was related removed and the carb was stripped to minium..

i think it spins at 250rpm

of and i was running 1gauge positive and negitive it helps alot..

 

Can you put a 2nd gen starter on a 12A?? I was thinking that you could...

 

Yes you can

 

No other problems. 20k on rebuilt engine, Holly 600 carb, full exhaust. She purrs like a kitten and runs like a cheetah.

 

Do you have any specifics on the 2nd gen starters? Does it matter what year you steal one from or all they all the same? I don't really have any complaints against the 1st gen starters. It just makes the car sound like a Model T Ford when it starts. I'd like to get something that is a little quieter, faster, and updated if possible. And heck, you can get a used 2nd gen starter for $20-30 so why not?

 

From what I am told, a 13b starter will bolt up to a 12a starter hole.

 

Hmm... In that case I wonder if we could just go ahead and use an FD starter??

 

Did some researching. Looks like any non-turbo starter will work. However, it seems like the FC starters don't have threads in them. So you would probably need a longer bolt and a nut to make it work? Not so sure that I want to try it anymore after reading this....

My car cranks at 300rpm, it might have been my thread that you were reading.

The two times I've used an official Mazda Rotary Compression Tester I cranked at 300rpm.

I just have a stock replacement starter, Bosch one from NAPA/Canadian Tire/Advance Autoparts / wherever.

The thing that makes the difference are your battery cables. Original ones are aluminum and they tend to get pretty corroded inside over the years. I replaced mine with copper wire, and went slightly larger on the size. Cost me about twenty bucks in materials and an afternoon's worth of work, and it was well worth it.

Now the starter gets all the juice it needs, and the car cranks nice and fast. It definitely makes a difference in starting and not flooding. I've done the same on two of my friends cars (replaced the battery cables, leaving whichever starter they had on there) and found a crazy improvement in cranking speed from that.

SO 2nd gen starters work just fine any model or just mt-mt at-at ????

 

And a 2nd gen bolt with nut.

 

so its a piece of all thread basically you got screw into tranny. Only reason i bring this back is my starter just **** out only way to start is have some hold key whilest i beat the **** out of it lol. should have known it was comeing most the time the starter just spun and didnt engage lol

 

heck im runnig a 12a starter on my 13b same bolt holes and everything till you get the the 13brew and some 20b's

 

Good condition OEM or equiv (bosch) 12a starter + new battery cables = 300rpm start.

Just installed a second gen starter and new positive battery cable in my car... its alot quieter and doesnt sound like its starting on a dead battery.. the thing spins like mad now..

 

auto starters spin faster. just swap the auto guts in to a manu case and there you go...
