Sr20det starter compatability with sohc ka starter
 

I have read that we can use hitachi sohc KA starters on our Sr20det by swapping KA parts over to SR. That’s great and all, but if I buy a sohc hitachi starter from a parts store can I get away with just swapping the SR20DET head on the KA starter? Sounds easy enough; Furthermore, I want to do it this way because not only is my starter not engaging (frozen up and works if hit by hammer), I believe the solenoid is going out. If anybody has a part number for the solenoid alone I’ll try that first, but if just a head swap works I would kill 2 birds with 1 stone. My sr starter is 23300-F5200. Thanks.

No, it doesn't work by swapping out the starter head.


You can use the internals in a Hitachi sohc starter to "rebuild" an sr20 starter. But on the outside everything will remain sr20.

So essentially I buy the ka hitachi starter to sacrifice the internals of that starter and install them into the sr20 casing?

Pretty much, there were write-ups online years ago. Thing is it must be a hitachi, and idk if the part store versions are the same.

Yea I’ve been searching for these write ups forever now and can’t find a trusty detailed one snywhere

Starters are cheap, get both and see if you can figure it out haha they're pretty simple.

Yea I just picked up a used sr starter, plan to get the last starter later this week, and then Frankenstein them together
