Clean it up, slap it back together, put a BP4W head on it with your shitty clutch, learn2tune, make supporting mods, then build a turbo engine. I'm gonna guess that VVT head is going to need work, the shims don't just pop out and everything is fine.

Got a message from the seller, he said they took the cams off, that's why the shim popped out. I took the head off, and removed the old pistons and rods. The #2 rod bearing was a little cooked to say the least, but the crank pin was fine and measured the same OD as the others. When I took off the mains I was well surprised to see good even wear, no signs of oil starvation, and the crank spins very freely with the pistons removed. Cylinder walls look pretty good and even have the cross hatching still fairly visible.

And I'm building this turbo engine now, that's why I got the second motor... I don't know if you missed it but I already have forged internals sitting right next to the motor waiting to go in. I don't know what the big deal is about the clutch, y'all are so butt hurt about using a stock clutch for stock power for some reason. I'm only going to use it for maybe 10-15K miles, just enough for the motor to fully break in. I don't care if I have to do double the work. 15K miles is a year away, it's not like I'd be dropping the trans twice within a week. I am in no rush to finish this, my main goal is to finish the engine first so I at least have something reliable in the car. Then later when I have the luxury of spending $4-5K on a turbo setup, I can take advantage of the forged internals and other goodies I put in before hand.

Because it's double the work AND costs money twice. You do what you want, but that's a pretty cut 'n' dry example of "stupid."

This entire thread is a convenient curation of every terrible question/idea that most people who don't research ask. The difference is that most people only ask 1 or 2 of them before they realize they aren't ready and need to do a lot more research. Or they rage quit.

So, kudos for hanging in there, but man... we didn't need the curation of stupid.

Also you can sell said new stock clutch, add money and get a proper clutch from the get go.
If you install it, it will have zero value and you will spend money twice. And twice the labor.

Well, more than twice the labor, since its cake to put a clutch with engine on a stand, but a bitch to pull transmission off an assembled car.

Ever pulled a transmission with the car in the air? 50x easier.

Ill buy a better clutch. I canít return this clutch, it came with the car when I bought it. Iím not losing any money by using it.

Maybe I can sell it, if I do then Iíll put some more money in and get a better clutch. Itís gonna be a while before the engine is ready to go in the car anyway.

I don't think anyone on this forum is thin enough to pull a transmission out of a Miata while it's on the ground. Not to mention you couldn't move the transmission out of the tunnel.

I'm not positive i do anymore.

Unless you were somehow insinuating that you're the only person that has ever done a clutch job on a 2 post lift?

It's a 2 hour job on jackstands too. It's not something you'd do "for fun" either way, so what is this part of the discussion actually about?

well... yes, i pulled and reinstalled 2 transmissions on 2 miatas, both in my driveway, on Jack stands.

its a royal BITCH to do, you need to remove manifold down pipe, exhaust midpipe, driveshaft, ppf, underbody nb2 bracing, center console and rubber boots and/or shifter, not to mention the PAIN IN THE *** bolts that actually hold the transmission, starter, clutch line, and electrical wires.

with a proper lift its a bit easier, but its still a bitch to do. With a million things that need to be removed and reinstalled.

Having done it a few times myself I would pay a few hundred extra dollars just not to have to do it twice because my time has significant worth. It is certainly not that I can't or won't do it.

I see it as being similar enough to the story of the young bull and the old bull standing on a hill.

i've replaced the transmission myself under jackstands as well. 0/10 would not reccomend. I'm either pulling the engine w/ trans next time or paying a shop to do it.

Assuming the car in question isn't leaky and/or rusty garbage, i really don't get the hate. I mean, it's not something i do to unwind on a Saturday afternoon, but it's not bad at all. It's less fun with a Qmax AND a Racing Beat header still attached, but it's a walk in the park if it's just one or the other.

IMO the PPF is the hardest part. And the slow realization that just about every time you do this job you're going to need to replace the shifter boots.

Leave PPF on car. Slide it off the trans, leave it attached to diff. Remove shifter boots with shifter first. (i personally haven't ever had one re-tear after i replaced it the first time)

Maybe it's just the desert air, but it feels like every time I can see my upper boot it's torn. Tried rubber conditioner, 303 Aerospace protectant. On boot 3 so far, haven't seen it in a couple years....

I'm guilty of being stubborn sometimes too but damn. It's nearly impossible to change someone's mind though.




(Also, for what it's worth, I don't any issues with the forum with either my old *** Note3 or my computer, and I have the infinity scroll and thread suggestions on)

Am I the only one who would rather pull the engine and transmission out, from the top, as a unit, than pull the transmission from below?

Pulling both is more pleasant but takes longer. I usually drop the trans if that's the only job I am doing.
