I want to build a spare block just in case. I picked up a bare block for 40 bux. I need a crank and will try to get all the parts to a machine shop for assembly. Ordering parts soon and thinking about a 949Racing CNC head.
edit: oh man, I think my EFR just blew. Looks like I may need a new block sooner than I thought

So I was driving home from Baltimore and noticed the car wouldn't go into boost. It did make a pretty soft howl and thought it was a boost leak. I inspected the piping and couldn't find anything until I looked down the turbo inlet. Picture soon....

Everything has been working fine until randomly I couldn't make boost. What causes this? Roasted bearings? Everything spins freely, but the shaft seems bent. I wonder if the turbine blades broke, causing the whole rotating assembly to go out of balance, allowing the compressor wheel to grind into the housing.
Thinking about quitting miatas.

Ahhhh man.... I can't believe your luck.
I bet the shaft is busted. Does the turbine wheel turn when you spin the compressor? The earliest EFRs were known for munching shafts/turbine wheels/everything.

compressor wheel turns, but it looks out of balance/wobbly. I couldn't dig my fingers to reach the turbine; it looks intact on the shaft though.
Seriously having to re-do everything is such a turn off. I almost don't want to undergo this anymore. All those aluminum shavings in the charge pipes and intercooler or whatever the motor has now ingested... It was utterly fantastic while it lasted. I just don't know if I have the will anymore

The motor is completely roasted. Cylinder head damage, looks like detonation eroded the piston. This build is fucked.
I already ordered internals for a spare block, but didn't factor in the cost of a head. I think I may have to let this one go.
Maybe.

So....
I ordered some parts but I'm not sure if I should be concerned. Supertech 84mm pistons 8.6:1 compression.
They look a lot shinier than I've ever seen in any photos. Is is possible that they missed the coating process? It doesn't even have any of their traditional logos or diameter markings. Maybe they aren't as flat or grey as I made them out to be?

Purchased a vvt head off 18psi. Going to ditch the Toyota cops unless I get ultra creative with mounting. Any recommendations for what to run instead?
LS2? Fab9? Find a stock system and wire in somehow?

I may end up going with the Fab9 kit for now. I don't have the resources or patience to adapt LSx coils at the moment. I'm going to pull the Supertech valvetrain off my old head and order replacement valves for the new VVT head and an inner spring kit to upgrade the seat pressure.
I have to figure out a way to pull the clutch out of the block so it can be balanced with the rest of the new motor.

it'll give me time to source connectors and get all the ms3 stuff sorted. I don't want to revisit it again later on. Thinking about a larger throttle body and having the squaretop matched but haven't decided yet.

Have to sell a couple parts first and really figure out what I need to do for knock module/ms3
