Default Moffitt's First Miata Build

The Car:

I picked up a 94 Miata M Edition 1.8L, Montego Blue with the Nardi wood grain shift **** and e-brake handle, aluminum sill plates, Torsen LSD and all the other M edition features...

With a clean title

For $400

The catch was...the genius before me welded the timing belt cog onto the crankshaft.

So it was decided to begin a project/build.

My Desired Goal is 300 WHP and a matching if not more than 300 WTQ with a 1.8L

PICTUREESS!!

Ok its time to catch up...

Well so far I've aquired the block shell and crankshaft.





Took them both to G&G Performance Engines just outside Tomball,TX to hot tank both of them and also have the crank polished.

I also decided to have the cylinders bored .40 over to 84 mm

Heres the block after the hot tank and .40 over bore:

That was a smoking deal for $400. It's going to be a nice car when you're done.

Alright so the engine build has come to a TEMPORARY stop due to starting a new job, However I went to the machine shop to pick up my block shell and crankshaft. After I arrived he informed he he also decked the block .005"

NOW....Im not coming to a complete halt on everything. While I am waiting for the right time to aquire the bottom end assembly, It's time to start the wire tuck

If you're going to pause for a while, make sure you keep that block oiled up and covered. Don't want it rusting.

Your car is going to be sweet. I still can't get over $400.

So you bored the block before you had the pistons? How did you set wall clearance?

The walls were bored just under 84mm. When I get my pistons and give them to my machinist, he will hone the walls to the clearance spec that he sees fit. And also I am going to have the top and skirts coated

Ug. Doing that would net me around 10 lbs of wiring that's stuck behind the heater core, but I still haven't done it. That's how much I'm not looking forward to it. As soon as a wire tuck requires me to drain the coolant I'm uninterested.
