Awesome flood of updates, just spend a good 15 minutes catching up. So to clarify, you now have a fresh bottom end and head on this thing?
I love the FD wheels personally. How do 17s look on mx6's? Have any pics? |
Well... the car isn't back together right now. Still need to rip the old ill-fated motor out, and assemble the new head.
But otherwise, yeah. Fresh not-"built"-but-optimized bottom end. The head is... well, you'll have to wait for updates. You'll like it. 17s look fine on mx6s. The first pictures in this thread were 17s actually. But with shitty 205/40-17 tires. |

Wait.. is that 1 intake valve per cyl? Headwork looks awesome, i'm kinda sad this isn't going into a miata.
jk :P |
2 intake valves per cylinder. 1 exhaust valve.
The headwork IS awesome. I'm expecting positively enormous gains, considering just how awful this thing was before it was touched. THIS one isn't going in a miata. ;) |
Just curious, that little area between your exhaust valve and spark plug hole looks a little suspect.
In the b2600i world (scaled version of the 2.2 12 valve head) that head would be drinking coolant... But we have heard that not all of the mazda castings were created equally and sometimes that crack doesn't make it to the water jacket. Then again it could just be that the 2.6 head stretched the design too far. |
Yep, two chambers have cracks between the spark plug boss and exhaust valve. Shitty casting. The two that have the crack have less distance between the two.
The head was taken to two shops and they verified that it's not going any further than surface. No sealing issues, and definitely not deep enough to get into any fluids. With the work done, heat buildup in that area will also be drastically reduced, so i'm not worried about it. Turns out this head was also a non turbo head, which may have something to do with it. But... a quick poll of the forums showed that half the guys that have looked have the same cracks. Next head for the miata will not have those cracks. |

If you're going to run old shitty things, ball hard.

Backdating again:
5/27/14 This is really testing my patience. Took a look at the new worked head that was to replace the previous worked head that got dropped. This is what i saw. FML. https://www.miataturbo.net/attachmen...ine=1403215237 |

Tack welded that piece back on, cutting the top edge flat because it warped a little, ground down the spots so they won't hit the lobe anymore, gonna turn it for a bit with some valve lapping compound in there. Then i'll run the bitch. #AINTCARE #YOLO #F2TLIFE |

Decided it was time to get dumb. https://www.miataturbo.net/attachmen...ine=1403215358 Yummy. https://www.miataturbo.net/attachmen...ine=1403215358 Well that escalated quickly. https://www.miataturbo.net/attachmen...ine=1403215358 Finally some pics of the old block for you. Dat carbon, tho. https://www.miataturbo.net/attachmen...ine=1403215358 Every line you see is a gouge deep enough to stop a thumbnail. Ran like a top. #F2Tlife https://www.miataturbo.net/attachmen...ine=1403215358 What's this? https://www.miataturbo.net/attachmen...ine=1403215358 Oh my. https://www.miataturbo.net/attachmen...ine=1403215358 *PUKE* https://www.miataturbo.net/attachmen...ine=1403215358 Threw this gross shit out, put the empty box back together. Way cheaper than ordering the actual delete pipe from Russia, and end result went from 9lbs to about 6oz. And more airflow! And no more gross shit! https://www.miataturbo.net/attachmen...ine=1403215358 Worn hinge repair. https://www.miataturbo.net/attachmen...ine=1403215358 Floor is wrinkled, popped a body plug out. I'll smack it with a hammer a few times then glue it back on after i remove all the deadening. https://www.miataturbo.net/attachmen...ine=1403215358 Other side. Pretty much all the wiring you see in here is being removed. Because fuck complicated shit. https://www.miataturbo.net/attachmen...ine=1403215358 Found a hole. Didn't pleasure myself with it. https://www.miataturbo.net/attachmen...ine=1403215358 Where did all this shit come from? https://www.miataturbo.net/attachmen...ine=1403215358 MANUAL ALL THE THINGS!!!!!! https://www.miataturbo.net/attachmen...ine=1403215358 TL;DR: Manual e'er'thang, already removed about 60lbs out of the car, have at least another 60 to go. Will be under 2500lbs with a full interior. |

Guess what we're doing today, kids? https://www.miataturbo.net/attachmen...ine=1403215418 This is a chassis harness. It is the enemy. It must be defeated. https://www.miataturbo.net/attachmen...ine=1403215418 *barf* https://www.miataturbo.net/attachmen...ine=1403215418 Looks way better like this. I should convert to carbs. https://www.miataturbo.net/attachmen...ine=1403215418 My fingers love this. https://www.miataturbo.net/attachmen...ine=1403215418 *Pile of shit intensifies* https://www.miataturbo.net/attachmen...ine=1403215418 This looks fun to wrap back together in the appropriate spots. We can wing it. We have the booze necessary. https://www.miataturbo.net/attachmen...ine=1403215418 *Pile of shit intensifies further* https://www.miataturbo.net/attachmen...ine=1403215418 Ok, so what have i done here? I've removed about 10lbs of wire, plastic brackets, and over 500 feet of electrical tape that are not necessary to be present in order to drive the car. Another 20-30 wires are coming out of the chassis harness once i gut the corresponding circuits in the dash harness. Quite literally... i will have removed 80% of the body harnesses. Me gusta. |

Hotside now coated inside and out rated to 2500F.
https://www.miataturbo.net/attachmen...ine=1403215457 Tried to take this apart because i thought it was serviceable. It is NOT, i repeat, NOT SERVICEABLE. Oops. https://www.miataturbo.net/attachmen...ine=1403215457 Apparently this was an auto-door-lock timer thing for once the car started moving. So many weird things on an 80s car. https://www.miataturbo.net/attachmen...ine=1403215457 Saturday's bounty. The white box in the middle is the CPU i was talking about that controlled the Opera Lights (Interior lights dimmed to off like a movie theater instead of just shutting off all at once) and the alarm/keyless entry. The silver box it's sitting on was some crazy shit that controlled all the speed sensitive things. (Suspension, steering.) The way it worked was mind-boggling. The car has a mechanical speedo cable and no ABS. Ready? Get THIS shit. There's a friggin' Hall Sensor built into the gauge cluster that measures the turning speed of the speedo cable at the cluster. Then sends electric signal to silver box. Silver box translates and sends commands to other two black boxes not shown. Active steering and active suspension. AND IT WORKED. DA FUQ. https://www.miataturbo.net/attachmen...ine=1403215457 Blurry pic of each of the 4 harnesses in the car after stripping. 1) dash harness 2) engine side body harness 3) Engine harness (Hilariously, the smallest of the 4) 4) Main body harness https://www.miataturbo.net/attachmen...ine=1403215457 |

Lubes for my pleasure.
https://www.miataturbo.net/attachmen...ine=1403215478 New brake rotors for the front... those are 6x6" square tiles. 12.6" rotors. Carbotech XP8 pads. #SWAG https://www.miataturbo.net/attachmen...ine=1403215478 Got sick of wrestling with rubber/generally shitty lines every time i dick with the drain on this. Fixed it. Other fittings for 2x -10AN valve cover vents going on. Also pictured: DW fuel pump wiring kit. (Thanks, FAP9!) Ordered bulkhead plug as well, will run 12awg all the way to pump directly, even in tank. https://www.miataturbo.net/attachmen...ine=1403215478 Will be running -10AN to each side of this can. Currently have a single setup. Moving to a dual was cheaper than getting a tri-way -10AN fitting. https://www.miataturbo.net/attachmen...ine=1403215478 |
The MX6 really have a hall sensor on the speedo? The miata has a reed switch.
