Don't have to modify the crankshaft they're all different from my original motor

I'm not understanding what your showing or asking? Nice cv-x. 15, what's your plans for that engine.

That engine is way too strong capturing up there years the car used to pop wheelies flipped over I didn't use it that much I had several more that one was my favorite the engine is super strong
I bought several engines and it's very hard to put them in there and everything is different on the other engines. The electric start doesn't even turn it over more than once
Ah yeah, failing to understand the gist of this thread. If the "problem problem" you lead with is having too many engines, that's a problem I'd like to have!
Cuz I had an outer cars and I would do engines but they're quite different I want to save the OS engine I was trying to find one week having a good start and it's very hard clutch shoes I cannot find it

I'm sorry man, I've read and re-read this several times and I haven't a clue what the point of all this is. Sorry, would like to help, but none of this makes any sense to me. Punctuation is your friend!

Now.you add a picture of shocks, so to me, you're randomly posting stuff with no actual point or question.

Take a breath, lay it out simply and completely and I'm sure we can help you out.

I'll take a stab at it -

Yes, there's 3 styles of crankshaft you're likely to encounter in nitro RC cars - long threaded shaft, short threaded shaft, and OS/SG shaft. There are variations, but those are the big 3. There's also Traxxas's IPS, but that's beyond the scope of the current discussion.

Your OS motor has a long threaded shaft, so do the VX-18's in your picture. You should be able to use them interchangeably with the correct tools, namely a flywheel wrench and a 10mm socket. A deep-well socket is ideal. They use a spacer before the flywheel, either with a brass cone or the shaft itself has flats for the spacer to engage. The flywheels for these have a straight 5mm bore. HSP brand replacement flywheels and clutch shoes will work for you, as well as for your ~25mm diameter clutch bell. That size is fairly standard for 1/8ths and most older 1/10ths. Kyosho and Traxxas occasionally go smaller, but that's beyond the point.

The force .15 engine (silver head) in your picture has a short threaded shaft, and will be harder to use as a replacement, because it uses a flywheel with the cone/collet attachment. Threaded shaft engines require a pilot nut, which has a straight portion for the clutch bearings, and a groove for the clutch shoes, whether they're 2 piece held by an e-clip or 3-piece setups with torsion springs.

I'm guessing from his name that English is not his primary language and is relying on Google translate which I know from experience does not do Tagalog justice when it translates. Hell, Google doesn't even call it Tagalog, it calls it "Filipino"
