Got a little work done tonight, not as much as I had hoped for, but what are you going to do. Here's the old motor sitting on the floor of my garage, just waiting to donate anything it can to the new motor.

And what we've all been waiting for. The new motor!

Now isn't that pretty....

The port work is unreal

Just a few quick shots I snapped tonight. Here are the specs on it:

short block:

bored 40 over with weisco oversized turbo pistons (8.6:1)

pouter rods

ARP main and head studs

All new bearings and gaskets

pistons matched to 0.001 to the cylinder walls

balanced and blueprinted 

lightened and balanced crank

mazdaspeed high flow oil pump

ford racing water pump

copper 3 layer head gasket

head

fully ported and polished

checked for flatness

0.5mm oversize intake and exhaust rev valves

stiffer volvo valve springs

ew retainers

new HLAs

stock cams/cam gears

port-matched intake manifold

I still have to install the HLAs and the cams, but I won't be doing that until the motor is ready to go in the car, as it's not good to let it sit without being run with the stiffer valve springs. The block, head, and valve cover were painted with a few coats of high temp engine paint, primed, and then painted red. I cannot wait to start getting this car together. These next few months it's really going to start coming together.

Here's another shot of the seatbelt attachment to the cage:

Yes I know it's filthy.

I had to enlarge the holes and get some different bolts. The old seatbelt bolt is bolted through the cage to the existing hole, and I got a new grade 8 bolt and mounted the seatbelt to the plate.

Moving on, took some pics of the finished rear bumper extensions. Again, I cut them down in size so I wouldn't have to deal with the smaller turn signal problem. I couldn't cut them down all the way, as the flare started about 1/2 way through the light, so I had to follow the contour of the signals and cut them to match:

Work has been slowing down because it's getting cold and dark fast. Once all the leaves fall down and the lawnmower is tucked away for the winter, I'll bring the car into the garage. 

I thought this was a funny picture. Here's where most of the miata lies:
