So in the US manual cars are sold to only be started with clutch depressed? Didn't know that

Can't you do this mod with a close ended cap type nut as well?

Habitforming

That is correct. It has been that way as long as I've driven manuals (late 80's models.) Dunno when it started. I actually didn't know until recently that most other countries weren't that way.

It makes one wonder if the thrust bearing arrangement should be designed differently due to that, and if they always are.

I wasn't referring to that diy. But is definitely speaks of what I am referring to.

However now that it has been linked here, I'd like to comment. Slipstream444 is 100% correct with his posts, and the effect on the thrust bearing while the clutch pedal is down (the crankshaft is being pulled against the rear thrust bearing)

If it were a push type clutch, the crankshaft would be pushed against the front thrust bearing.

I didn't know the S2000 could be started without pushing the clutch in other parts of the world. Dumbed down usa I guess.

My car has 140k, 130k of those have been with the old style ACT pressure plate (very strong)

I have checked my crank thrust, and it is that of a brand new engine. I attribute this to the clutch interlock bypass. It goes a long way towards greatly extended engine life, but obviously you need to be smart about it (accidental starting in gear)

Props to Scott for NOT offering a "built" engine, and offering the BEST solution at a very fair and realistic price. You can now start from the beginning, and in time you will learn how indestructible an OEM short block really is.

Billman, Thanks for this comment. We did briefly discuss an engine rebuild, which would have resulted in a "better/more powerful" engine. There was someone with an S2000 that I met that Scott rebuilt his engine with numerous "upgrades". It was obvious to them once we talked, that I wanted my car back just like it was before I had the problem. I was told that the new block was the most "cost-effective" and quickest repair. It was a "no-brainer" for me. I'm glad you assured me that it was the right decision, and for letting me know that the price was fair.

FYI the DIY post @ https://www.s2ki.com/s2000/topic/619...switch-bypass/ gets cutoff in the end and is incomplete (a lot of old posts seemed to incomplete/corrupted after the s2ki buyout -- nice!).

Can anyone finish or write-up a better DIY?

Why don't US manufacturers tie the interlock to the gear instead of the clutch position? Safe to start if in neutral, and not safe if in any gear. What am I overlooking?

Because then your kid can just start the car and not be able to shut it off and die in garage full of carbon monoxide. So everyone compromises for the cheapest solution to little Johnny taking a big whiff of odorless death, amongst other things.

Doh! You're right. Child safety is a huge driver for features like this. Not just adult stupidity!

All very educational. Thanks.

My takeaway: 1) When you put your car away for the winter, don't start it until ready to drive it out of the barn in the spring. 2) Pull the fuse for the fuel pump, then spin the engine to build oil pressure. (question, will building oil pressure show up on the cluster?) and 3) disable the clutch interlock for even longer engine life - provided you can retrain yourself not to engage the clutch when starting.
