HPDE Fail- 240's engine build
12 Attachment(s)
So as some of you know, my poor little 1.8 didn't survive my first track day. It started making some ticking noise when warm... sounds like the classic Subaru piston slap. Most likely rings and/or wrist pins are fucked up. :vash:
Just for shits I got a blackstone lab report to maybe confirm what I thought before tearing into the motor. It showed high amounts of aluminum and iron... https://www.miataturbo.net/attachmen...ine=1341783075 So... Time to rebuild. Between finishing my paint project, buying xida CS's & TSE 11.75", I am broke :ohnoes:. . . So I plan on only building the bottom end and "refreshing" the head with a valve job & new seals. A yr or 2 down the road Ill go VVT. I plan on: -Supertech 9:1 84mm pistons -M-tuned rods (already have them in the current engine. gotta check that they are still good) - ACL Race Bearings - ARP head & main studs - Boundary Street/Strip highflow pump (shimmed) - TSE Inconel turbo studs - Fresh rebuild on the turbo, powder coating, etc. So far I have most of the parts. My pistons came with no rings but emilio says they usually ship separate. I will be bringing the motor to Center Auto in Stratford, CT. They will be doing all the machine work including balancing the rotating assembly. They also are going to be assembling the short block so I know its right. I pulled the motor today. My 10x15 unit is REALLY tight but it gets the job done. https://www.miataturbo.net/attachmen...ine=1341783075 https://www.miataturbo.net/attachmen...ine=1341783075 https://www.miataturbo.net/attachmen...ine=1341783075 https://www.miataturbo.net/attachmen...ine=1341783075 PACKED https://www.miataturbo.net/attachmen...ine=1341783075 |
Your engine is making metal. That can't be good.
Did you get new flywheel bolts yet? I have an extra new set from the dealer is ya haven't gotten them yet. |
Nice hoist.
|
harbor freight ftw...
LOL its my buddies. I refuse to buy a hoist before I own a garage EDIT: Martin, no I haven't grabbed those yet. |
If it makes you feel any better, I have that same sized garage space, a tire trailer, three extra sets of wheels and tires, two spare engines, two spare transmissions, two rear ends, a rack for bulk fluids, a hoist, trans jack, and a work table...and the green car. It sucks.

So do you park the green car outside the garage then?

I thought you store it places like that wont let you work on cars... I feel cramped just looking at the pictures. Makes me appreciate my 25x50 WAY more!
Oh, and ditch that silly evap canister. |
They technically don't... but I have never run into issues. usually the management is pretty cool. The one that I have during the winter/spring in my parents town is awesome. 10x30 and they are really cool about car stuff. They let me run a 100ft extension cord and grab power.
I will be ditching emissions ---- after I pass. I am a yr late so thats mission #1 when the motor is running. My reg. expires jan 2013 so I NEED to do emissions this fall. |
Are you building this motor yourself? If so please document everything!
Sorry to hear you popped your other motor, but glad to see it going back built. GL! |
I am not assembling the short block. I assembled the last one and it all went ok but with some high dollar parts & machine work going into this one I think $200 for professional assembly is cheap insurance.

HOLY WAR ZONE!!!!!
https://www.miataturbo.net/attachmen...ine=1341967391 Engine goes to the machine shop Thursday!! All I can see from having the head off is some slight detonation on cylinder 1, and some slight markings on cylinder 4 wall. Its still very smooth tho. I think the det was there last time I had the head off, so I am still guessing cylinder 4 rings or wrist pin is shot. |
Sounds like bearings to me. Let me know if u need any help.
|
Hope you get the car back together soon, i love your car definitely subscribing to this thread!

Evan (adriver1990) was right... rod bearings. I trashed all 4. Luckily I stopped early enough where the crank and rods are still okay and I can still use standard bearing sizes... I swung by the shop before waterfest to see the damage: https://www.miataturbo.net/attachmen...ine=1343773377 https://www.miataturbo.net/attachmen...ine=1343773377 https://www.miataturbo.net/attachmen...ine=1343773377 Hopefully I will get the engine back in another week or so. I am still missing the oil pump. In the mean time I am rebuilding the turbo, powerdercoating parts, and upgrading to TSE INCONEL M10's https://www.miataturbo.net/attachmen...ine=1343773377 I F'ed up my manifold machining out a broken M8. I lost the center and ended up oblonging the hole. My solution was to use keyed threaded inserts because they cant back out. Only issue is I plunged a bit too deep and broke thru into the inside of the manifold. I am hoping that the exhaust gas wont leak thru the threads... https://www.miataturbo.net/attachmen...ine=1343773377 https://www.miataturbo.net/attachmen...ine=1343773377 https://www.miataturbo.net/attachmen...ine=1343773377 https://www.miataturbo.net/attachmen...ine=1343773377 I think I am going to finish rebuilding the turbo tomorrow and then use the eastwood hotcoat powdercoating gun to do my valve cover later this week! Oh my friend also welded up some IC pipes for me. I haven't picked them up yet. |
Got my Boundary street/strip oil pump. Next week I will be picking up the motor and then I will start assembly of the long block!
|
Nice. What did you end up doing about the bearings for the turbo?

Finally picked up the motor...
https://www.miataturbo.net/attachmen...ine=1344987786 https://www.miataturbo.net/attachmen...ine=1344987786 https://www.miataturbo.net/attachmen...ine=1344987786 https://www.miataturbo.net/attachmen...ine=1344987786 Also cleaned all 16 of my HLA's. Took ENTIRELY too much time...but they are all squeeky clean and feel really smooth. I wish I still worked at The Lee Co, I would have slapped them in the Branson Ultrasonic cleaner. I did loose 2 springs so I grabbed a spare HLA from a friend and will steal the parts from that. https://www.miataturbo.net/attachmen...ine=1344987786 https://www.miataturbo.net/attachmen...ine=1344987786 I will hopefully get a chance to start assembly soon. |

Almost ready for powerdercoat. I'll be using the Eastwood powdercoating gun again. I am tempted to put AN fittings in, but for now i think I am going to keep the stock PCV & ghetto mini filter. I will do a catch can setup in the spring. |
Wow, looks great. How much $ do you have in that motor? Looks like a solid build.
