TL,DR: NAPA carries the bolts.

I gutted the Triumph and left all the parts strewn about with boxes piled on top of them, then put a bunch of Miata parts inside the Triumph :giggle: I took pics of the garage but they were frightening so I deleted them. :party:

I actually used SAE bolts to attach mine. I went with the SAE size that was slightly smaller than the OEM bolts so that they would fit inside the metric threads, got long bolts, and put nuts on the other end. Cheap and easy to get at OSH. :)

I don't have any gutted cars in my garage, but I have got entirely too many spare Miata parts littering the place. 2 spare 5-speeds, a 3.9 torsen, 2 spare oil pans, a set of 11.75 brakes that need to go on the car, a spare set of 11.75 rotors for the the track pads, the old engine block, a warped BP4W head, two or three spare alternators, an old FM radiator, etc. I need to get rid of some of that crap. I did at least manage to sell the boat anchor 16 inch 2003 wheels that came on the Seven and put the old Team Dynamics on it instead.

What kind of Triumph?

New Year's resolution . . . clean the garage!

18psi 12-23-2014 10:23 AM

amen to that.

I think we need a support group for this. Mine is not as bad, but all the shelves are so disorganized I rage when I look at them.

I did that once with a Ford 302 back when I was about 20. I didn't have correct hardware so I just through bolted with what I had lying around. I broke one of the bolts while tightening the head. Scared the bajesus out of me so I've tried to make sure I use the correct bolts ever since.

Crazy orange TR6. I have a "build" thread on NorCalRoadsters I haven't updated in ...quite some time.

https://www.miataturbo.net/attachmen...ine=1419355597

I wish we had a build thread section that catered to non-miatas. Stuff like Stein's weird Peugeot or SAAB or whatever, Vlads various impulse buys, my Triumph, Ian's Lowcost... I know other people have other projects as well.

Mine was so bad until I bought a big ass tool box and storage bins. It wasn't so much me being messy as it was not having adequate storage to put stuff. Not all of us can have a garage space like Jeff lol

That's a cool Triumph!! I didn't think we discriminated in our build threads. Don't we have a few Subarus coming together?

When I start putting my Sport Fury back together, there will be a build thread! Chrome and big blocks, baby!

Exactly! I'd be tempted to start a thread about my 73 F250 as well, just to keep me motivated and keep track of things. I posted about it in the Front Desk section, let's see if it gains any traction.

you know, I think you're onto something here. reading others' great progress and awesome build threads often motivates me to do stuff with my own cars instead of putting it off lol

hornetball 12-23-2014 01:38 PM

Yep, build threads are a great way to spur cash expenditures! LOL.

The BP weighs a lot less than a Windsor! :) I think going SAE also helps because you don't have to down in size as much as if you were trying metric ones.

Cool TR6! A build thread on my Seven wouldn't be that interesting -- I bought it from the guy who built it, and I haven't done all that much to it myself. Mostly just fixing some of the more egregious mistakes in it, things like 50 psi fuel hose on a 60 psi fuel system held on with worm gear hose clamps pushed onto the non-barbed ends of stock fuel components. That and the suspension arms that differed in length by 3/4 between the left and right sides... :vash:

That's like a nascar, helps it go around corners more gooder. :laugh:

Son of BEECH! SHEET!

I actually paid money for a physical copy of the Mazda factory BP engine assembly manual, and now I can't find the damn thing. I bought it at the same time I bought the physical copy of the FSM for my 2000 and somehow it didn't make it into the binder. Shit's gone now. I hope someone has a PDF hosted somewhere, time to do some searching :vash:

Progress!

https://www.miataturbo.net/attachmen...1&d=1419807629

Rods and pistons out

https://www.miataturbo.net/attachmen...1&d=1419807629

Dem bores and such

https://www.miataturbo.net/attachmen...1&d=1419807629

The rod journals are PERFECT. Rod bearings look PERFECT. No scoring, no marks, no nothing. I may not even have the rod journals polished at this point. They all measure out within 0.0005 of each other, which is convenient because the tolerance on the calipers is +/- 0.0005 :giggle: I've got a set of legit mics I'll employ at a later date, but that's close enough for now. I still need to come up with a set of tolerances for the rod bearings, but I'll keep looking.

It's stripped down to just the block and crank, and I'll pull the crank later this afternoon. I expect no issues from the crank bearings either. With any luck, none of this will be in my hands any longer by Monday afternoon. :)

I almost feel bad having torn this motor apart, its silly how clean it is inside. Almost. :party:

hornetball 12-28-2014 07:16 PM

It definitely looks good so far!

18psi 12-28-2014 07:18 PM

Yep, that is one healthy lookin bp bottom end

Ok, maybe not as perfect :giggle:

That's #1 block side (obviously)

Also #1, but reverse angle. No galling but definitely scuffed.

Here are the caps, #1 is a the top, #5 at the bottom. Orientation follows as they would have been installed in the block, looking down. They all have a bit of polishing, #3 is the almost the worst...

Solid closeup of #3. That looks like FOD to me.

Closeup of #5. Right side of the image would be the front of the block. The strange ring shaped indentation is super bizarre. It almost looks like something got in there when they originally installed the bearing and cranked down the main. You can also see where there was a small amount of material embedded into the bearing.

Thrust bearings look pretty damn good if I do say so myself. Top one is the rear facing.

Attachment 238539
Workbench is starting to accumulate stuff again, I need another box of ziploc bags. :loser:

I couldn't get good pics of the crank surface due to the lighting, but there was absolutely nothing alarming to be found. This makes me feel a bit better, but I might go with the micropolish now anyway, just to be sure.

Also of note, there were no copper washer gaskets around the oil squirter banjo bolts.

I felt the same way with the block I tore down to build mine -- then I noticed that one of the rods was banana'd. Are the ones that came out of yours all straight? :)

They look straight to me. I'm not sure the Rotrex ever made enough torque to put them in serious danger ;) The rod bearings actually look about 10,000x better than the crank bearings do.

Also, picked this up today:

Winning! It should be here before the block gets back from the machine shop. If I'm feeling ambitious I'll cut it out of the binding and scan it. :party:
