Good logic. I'm going to continue to skip out on them in my builds til I hear of someone failing the stock bolts.

So you're just doing a bore and hone? Are you going to have the crank ground and/or balanced or anything like that?
I'll just need your: Pistons Rings Rods Crank Main Studs OPGs and an oil pump if you decide to go that route. You can probably handle the OPGs yourself though if you wanted. I can figure out the bearings and order oversized if necessary. If you're not getting any crank work done then it probably wont be though. I didn't have to for mine. I love engine building. Probably my favorite thing to do. I think I am going to have the crank balanced as well... I'll bring my head down as well and we can just put the whole thing together and ready to be dropped in. :D |

To be honest, I've never used them personally for this very reason. I was going to on my last DSM, but I was talked out of it by my machine shop since I had already bought bearings and whatnot.
It seems to be a 50/50 split. I agree with you that it doesn't necessarily make sense 100%, but if it is absolutely overkill, and 50% of engine builders say that a bearing failure could end up being the result, those aren't good enough odds for me. If I had unlimited cash flow, I'd do it anyway since I've never seen definitive results, just opinions. |

so stock bolts it is. but new ones. I AM going to get ARP head studs though. And a cometic head gasket.

In my build, just finished, I researched all the same stuff. ARP bolts for the connecting rods, ARP head studs, stock mains. Seems to be the typical configuration around here.

kday has a nice setup, although you do need to know a little programming. I'm working on a similar setup that should be done in a bit...

That display is pretty awesome. If I hadn't just gotten some custom gauge faces done, this would probably be on my to-do list.

That engine was given a break-in just as described in another thread active on here. With the other stuff I was doing at the time, it got an oil change about every 1000 miles, and it also got one after the initial few minutes of running and another after the break-in. It had awesome oil pressure from the brand new pump and front case. It ran wonderfully cool with the brand new water pump, removed AC, etc. It also ate its thrust bearing in about 8K miles. I did not measure the actual end play, but eyeballing it I would say maybe 1/4. Yes. Inches. I am guessing no alignment check on the awesome new mains. Stock mains and alignment check FTW. The new shortblock got that, and it is now powering my freinds Talon after doing great in my old car. |

I (stupidly) ordered a G4CS (4G64) 6 bolt shortblock from a company that shall remain nameless (they are not in here or in the Miata scene at all). I specifically specified stock mains and ARP rod bolts. I got ARP mains. Hey, cool, freebee!

I leave this thread for a few days and it goes from gauges to engine rebuilds to DSMs if I'm not mistaken?
Where's the OP and his prototype gauge setup? I figured it'd be done by now. |
At least it has not moved to a picture of a bike with a dildo for a seat.
Good point though. How about it OP? |
Working on it. Got a few things to deal with car related right now... this is not one of the front runners.
Gotta fix a few things before the next track day in a week. |
why dont you try getting this to work with your car. their pretty cheap.
