I would definitely reuse the rods but at that point it would be "sell block whole vs. part out block minus rods".
|
You bitch! I was trying to buy this engine.
|
Sorry. Be happy I saved you from it.

Haha it's cool, is it really that bad? I know you got a deal on it ;). I'll still take it if you wanna sell it.
|
It's not too bad. Just that hole in the exhaust valve. I may sell the head, or just part the whole thing, or keep it...I haven't really decided yet.
If there's something specific you want, PM me an offer, I'd consider it. Bird |
That bottom end is hosed. I see det damage on all 4 pistons.
Why in the hell is there a single billet main cap? |

Why in the hell is there a single billet main cap? So what exactly does the det damage look like? Not sure what I'm looking for. Any opinions on if it's worth repairing the head? Would you consider anything from this motor salvageable? And Center cap was FM's thing ten years ago I guess... Bird |
Ok...so I googled it and found a few decent pics of mild det, then got led back here:
https://www.miataturbo.net/engine-performance-56/built-motors-detonation-42072/ I guess I was looking for more catastrophic damage... |
The top of the piston should be completely uniform in finish - in your pictures, at the edges of the piston near the valve relief, the finish gets rough and changes in color. That's the detonation damage - it's mild but it's definitely there. We can't see the ringlands, but I bet the same style of damage is on those as well (or worse).
I bet the head is salvageable, though. You might want to take it to a local machinist and have him take a look. Or you can send it up to us and we can have our guy go through it and refresh it - new guides, 3-angle seats, etc. |
cool build here! looking forward for more :)

More pictures...because everybody loves pictures.
Some pics of the head: https://www.miataturbo.net/attachmen...ine=1330672098 https://www.miataturbo.net/attachmen...ine=1330672098 https://www.miataturbo.net/attachmen...ine=1330672098 https://www.miataturbo.net/attachmen...ine=1330672098 Here's what the crank looks like, some scoring. https://www.miataturbo.net/attachmen...ine=1330672098 https://www.miataturbo.net/attachmen...ine=1330672098 Rods: https://www.miataturbo.net/attachmen...ine=1330672098 https://www.miataturbo.net/attachmen...ine=1330672098 And just thought I'd share this tip. Harbor Freight sells these cheap, and they're great for storing fastners from stuff you're taking apart. https://www.miataturbo.net/attachmen...ine=1330672098 https://www.miataturbo.net/attachmen...ine=1330672098 I use this stuff to clean up some of my small parts and hardware, but it will strip plating from bolts if you leave them in too long. https://www.miataturbo.net/attachmen...ine=1330672098 Bird |
There was a guy on the forum selling a complete set of valves for a good price recently. Not sure if he still has them, but would be worth a look.
|
Was that Y8s? I believe Hustler bought those.

Just got 4 of these from Trackspeed in the mail:
https://www.miataturbo.net/attachmen...ine=1331008205 Tomorrow I'm taking these, the Carrillo rods from the FM motor, and the '00 head and block down to a machine shop. I'm going to have to use the crank from the 95, the keyway in the '00 crank was messed up making it unusable. It looks like a botched timing belt job is what caused that motor's demise. Still need to order the BE oil pump, I'm bummed I missed the GB. Hopefully in a couple weeks I'll have new built motor pics to share. Bird |
What machine work are you getting and how much is it?
|
Hot Tank
Magnaflux Bore, Hone for pistons Deck Line Hone $325 Rods are $15 a piece if they need machining, I forgot what he said for Maganfluxing those but it was cheap. |
damn, that is cheap :O
|
Yeah, I was surprised. I'm having it done at Eddings Engine They also quoted me $300 to do the valves on the '00 Head, more if it needs any parts replaced.
I think I'm going to just have them assemble it too. I haven't talked to them about that yet though. Bird |

Haven't updated in a while, not much progress on the car. I got my engine from the machine shop a few weeks ago, but life and work have got in the way of working on it. It's ok though, I needed a break, and I've been playing with something new...
Here's the engine while test fitting and picking oil drain location. I had AN bungs welded onto the valve cover and oil pan. https://www.miataturbo.net/attachmen...ine=1340488486 My girlfriend's new car is what has really been taking up my free time though... *Warning-Non miata content below (but it does have a turbo) https://www.miataturbo.net/attachmen...ine=1340488486 https://www.miataturbo.net/attachmen...ine=1340488486 https://www.miataturbo.net/attachmen...ine=1340488486 https://www.miataturbo.net/attachmen...ine=1340488486 https://www.miataturbo.net/attachmen...ine=1340488486 |
