Yep...logging of oil pressure and temp was on the list, but not yet executed. Kicking myself for that one. Hoping there is some evidence on the other bearings one way or the other. I'll also be checking the other rod bolts with a stretch gauge.

4Piston suggests that the Manley rod is good to 9000+ rpm in this application. And I have spun that high in an autocross situation for a brief moment. Heck, I've spun a 4Piston built K20 (shorter stroke than K24) with the same rods to 9500 rpm in an autocross with no ill effects.

Although Andy and I have talked about this in depth already, I just want you all to know that we're here to support him and dig into any issue that could have possibly stemmed from anything on our end. I think it's unlikely, but of course we don't want to jump to conclusions.

Of course its a bummer that oil pressure monitoring or datalogging in general hadn't made it into the car yet.

Andy, I'll talk to you later this week once you get to dig in to the motor a bit more.

Material defect in the rod bolt? Hydrogen embrittlement of said bolt?

Seems unlikely but who knows...

Mazda/Honda dropped, for a McLaren?

I'd say something SPECIAL surfaced today..

Tis true.

Ran out of time on the Miata to fix it right, so opted for something turn-key and quick as Plan B.

Good deal on the car means I can't really lose money on it (assuming I don't ball it up). And it gives me something fast to track when the other cars are laid up.

Andy,
Did you ever pinpoint the problem for this failure?

And any update on this kmiata?

No further progress on the diagnosis.

I put my stock TSX K24A2 in it a couple weeks ago and its running again. Wearing VR1's on 15x10's to fill out the fenders for now.

I've been kinda house-bound with Ann's knee surgery recovery, and the new shiny orange object has also been a distraction.

And to make matters worse, I just started buying parts for my ND to prep it for autocross.

Is this coming back for next year or is it dead?

I love the wider fender mod. If I have the money someday that's exactly how I would like to do it.

Andy has a McLaren to play with, so chances are slim lol!

It will get some love, yes. But as mentioned earlier, I now have four projects going on, so doling out time is a challenge.

Biggest hurdle at the moment is coming up with a headlight solution. The front tubbing was a touch too aggressive, and even the shorter NB2 headlights won't clear now. Plus, I have to completely re-do the CAI since that hole I was using got bent upwards to become the inner fender. There's a new center feed version of the Skunk2 Ultra intake manifold that might allow for better packaging w/o any performance loss.

For the moment, the CRX and 12C have been getting all the big-track love, while the ND gets used for Harris Hill and cone dodging. See the next GRM for more on that one.

If you have a really good imagination you can see him driving it around Road Atlanta last weekend in this really poor quality video.

I wish there was a HQ link to some of these.

Thanks! That's a lot better. It is still somewhat blurry but I guess that is from wind buffeting the camera. It has been a couple of years since I went to the Toy Run. I need to get back to RA.

That HUD software is really awesome, I gotta get myself something like that.

No. I know that car (owned by Will Chan), but mine is naturally aspirated. More details at OneLapCRX.com
