 | January 25, 2011 - The work begins.
It'll be a while before we have the drivetrain, but first the existing high-compression setup has to come out. It's a bit of a sad moment, that's a really nice setup and the car is very well balanced. But it will be reborn stronger and faster! The current engine and the header have been sold and will live on.
While the car was originally built on jackstands in my home garage, it will be rebuilt on a lift in the Flyin' Miata shop by the pros. This will be a nice change of pace.

 | January 25, 2011 - While the car is being pulled apart, the extra pieces will be safely stashed away.
Starting with the coolest looking hood and trunklid ever seen in the FM shop.

 | January 25, 2011 - Goodbye, faithful 2.0.
This engine has been rock solid, the perfect companion to a rally/track Miata.

 | January 25, 2011 - That didn't take long.
A couple of hours after Adam started working on the car, the drivetrain was out. Since then, the engine's been split off and the suspension pieces have been stacked to one side. It took a lot longer to build it than it did to take it apart!

 | January 27, 2011 - Time to mount the Getrag differential in the rear subframe.
There's a cross bar that mounts the back of the diff, but we need to weld two tabs on for the front. The stock rubber bushing has been removed and replaced with a polyurethane part for better control of the diff. It's held in place with a set screw.

 | January 27, 2011 - The car's looking pretty empty by now.
It's almost time to start modifying the shell.

 | January 27, 2011 - The Targa car started off as a 1994 R package, which had a long career with an FM II turbo installed.
At 200,000 miles, it was taken off the road, stripped and seam-welded. You can still see some of the clearancing for the turbocharger on the frame rail by the driver's shock tower. It's time for some much more intense engine bay modifications though.

 | January 28, 2011 - The car continues to come apart.
We need to open up the transmission tunnel a bit to clear the large bellhousing required by the V8 engine. Because this car is so stripped out, I figured it would be possible to do the work without pulling much of the interior. But, because the car is so stripped out, it didn't take long until it's stripped even further. And now it'll be easier to work on.
The dashboard support was welded in with a couple of supports to the firewall and the tunnel. Those had to be cut. But they can be mended easily.

 | January 28, 2011 - Because the V8 is a thirsty beast, the complete fuel system is going to be replaced.
All the fuel lines will be -6 AN (3/8") stainless braided lines, running a returnless system at approximately 60 psi. For the higher fuel volumes and pressures, the pump is being replaced with a higher-flow unit as well.
We're installing the fuel pump/fuel level assembly from an NB Miata because it's got nice push-on connectors. This isn't totally necessary, but it does eliminate a few adapters and makes for a cleaner install.

 | January 28, 2011 - The first step in modifying the engine bay is to strip off all the paint and seam sealer.
This is not a fun job at all.

 | January 31, 2011 - With the interior of the car completely stripped, Adam continues the prep work for the tunnel modifications.
First, the factory braces on the sides of the tunnel are cut off. Then the seam sealer is removed. The braces will be welded back into place once the modifications are done.

 | February 1, 2011 - The surgery has begun.
The corners of the firewall are cut out, and these reinforcing plates will get welded in.
entry 788 - tags: body |
| |
 | February 4, 2011 - The tunnel has been widened.
It's not an obvious change, but the seam along the outside edge was been opened up. We need to check clearances using the plastic engine, a bellhousing and a subframe - but we don't have the subframe yet. So this will remain half-finished for a bit.

 | February 4, 2011 - The chassis was seam-welded before the transformation into the Targa Miata began.
But nothing had been done in the engine bay. While waiting for a subframe to show up, he finished the job using the diagrams out of How To Build a High Performance Miata. He also did some work in the wheel wells.
This makes a big difference in the car. I've been driving around in a Miata that's seam-welded and fitted with a set of FM frame rails, and it's a remarkably rigid chassis. It'll really help the front end deal with the torque from the big engine.

February 8, 2011 - We're seeing a very good response from the Miata community.
The support can only be called amazing - we've collected nearly $8500 worth of pledges for us to return to Newfoundland. In order to send the planned two-car team, we need to raise at least $10,000 by March 10th. What's special about that date? That's the six-month point, after which the financial penalties for withdrawal go way up.
But at this point, we know for sure that the Targa Miata is returning along with Janel and I. And that's excellent news. A big thanks to everyone who's helping us go back. I think some of the other folks at Flyin' Miata are a little shocked at how much is involved from a planning viewpoint to make this happen.

 | February 8, 2011 - We have a new sponsor!
Wiseco is going to provide pistons and rods for the Targa Miata engine. The engine is an all-aluminum 5.3 known as an "L33" or a 5.3 Vortec HO that's being rebuilt by the wizards at V8R Spec to a healthier specification.
The Wiseco bits will make it stronger, better able to handle the punishment of a motor that will live on the racetrack and rally stage.
The Targa Miata actually ran Wiseco pistons in the four-cylinder engine as well.
We don't have pictures of the parts yet, we'll put one up once we have them.

 | February 14, 2011 - The V8 Roadsters front subframe is here - and it's a beautiful thing.
We also received the differential mount. More V8 Roadsters parts are coming, but the subframe will allow us to double-check our transmission tunnel modifications and move forward with the work.

 | February 18, 2011 - A gift from Eric: a real Martini Racing MOMO steering wheel.
It's from a Lancia Integrale and was shipped to him from Italy. He's going to send it my way.
Totally unnecessary, but very cool.

 | February 25, 2011 - The frame rails have arrived.
That cross bar will support the T5 transmission. As an added bonus, these rails will help protect the bottom of the car and provide an excellent jacking location.

 | March 2, 2011 - The transmission has arrived.
It's a T5 with the following ratios:
2.95
1.94
1.34
1.0
.63
There's always some concern about the strength of a T5 in this sort of application. However, it's the same one used in the V8R Spec series. The big advantage we have is weight - there's a world of difference between launching a 3000+ lb Mustang and our 2300 lb Miata. We will be adding a cluster support to help it out.
