Exocet Update 7: Reassembly
- Jan 1, 2025
- 21 min read
Putting things together isn't as easy as taking them apart.
With the Exocet frame mated the the powertrain, the list of things to-do greatly expands and the path of progress becomes non-linear. Things to do include (the list below is not exhaustive):
Foundation Brake System:
Mount front brake soft lines to frame (both sides)
Create front brake hard lines (both sides)
Secure any loose lines to the car
Mount brake booster vacuum line
Secure, fasten clutch line
Mount engine bay components:
Intake and Mass Air Flow sensor (MAF)
Exhaust Gas Recirculation (EGR) sensors
Fuel tank emission recirculation sensor
Power steering (P/S) reservoir
Close the cooling system:
Mount radiator
Plumb coolant system including a heater core delete
Install a coolant overflow reservoir
Close the fuel system
Install fuel tank
Route fuel soft lines at the rear of the car
Install a fuel filter in the fuel send line
Attached soft lines in the engine bay
Route a rollover valve and fuel vent system on the fuel tank
Install the steering column and gage cluster
Clean up battery wiring harness at rear of car
Reinstall the donor wiring harness
Install a functional exhaust before starting the car
Some of the above items were straightforward reassembly of donor components. Others needed unique solutions to complete. Challenges we faced and our design choices include:
The frame was powder coated already meaning we did not want to weld mounting points for things to it:
We used split clamp tube mounts of various sizes to create a mounting point where needed on the frame, these are commonly sold for ATVs and UTVs to mount lights and other accessories to their tube frames
Placement of the mounts needs careful consideration so that the mount can be removed if needed (try not to place the mount where you cannot access the hex key cap head bolts holding it together)
There is no front brake soft line mounting point, the soft lines much be mounted so at full steering lock, they are not in tension or are not rubbing suspension/chassis components:
Multiple ideas and iterations of designs were tried before we found a solution using split clamps and fabricated brackets that worked and also allowed clearance for installation, modification of other components, and attachment to hard lines
We needed the car in the air with wheels on to turn the wheels lock-to-lock and verify that tension wasn't on the lines and they didn't rub the front A-arms or chassis
The rear bulkhead of the Exocet is within a few inches of the rear subframe (there is significant clearance on the donor Miata):
The rear parking brake cables will rub against the frame and there is no design consideration for mounting them so they rest on the driveline if not supported
The rear subframe brake splitting block is almost against the rear bulkhead making a traditional hard line impractical, we used a banjo bolt and braided line (custom) to attach the rear split block to the rear hard line coming from the transmission tunnel
Specific, thicker crush washers were needed to install the banjo bolt on the rear split block
The steering geometry is different between the Exocet and donor Miata:
We had to use a vice grip and dead blow to extend the splined column (that sits in the engine bay)
We had to use a metal pipe fitted over the column while it was rested steering wheel down on cardboard, hit with a dead blow, to properly fit the column between the firewall and dash cross member mount
A small corner of the header heat shield was trimmed away to clear the column in the engine bay
The engine bay is much tighter between the shock mount points, the height of the Exocet hood is much lower, and the radiator mounting point is 3+ inches closer to the engine than in the donor Miata:
The OEM intake box does not fit at all in the Exocet
We used a cone filter clamped to the nose of the MAF, a specific size is needed to fit between the header heat shield and shock tower
The intake mounting needs to consider that the MAF and intake filter need to be fixed between the header and shock tower
The power steering lines interfere with the OEM NA Miata hard line and soft lines for the lower radiator connection, a Flyin' Miata NB style hose cut down slightly was able to clear the P/S equipment and subframe
Any items mounted in the engine bay had to be low enough not to interfere with the hood, this includes the radiator which must be mounted in a very specific location for the 1.8L style air intake (this may not be the case for the 1.6L style intake), see the next point
The clearance between frame members at the front of the Exocet is minimal, placing the radiator mounts is very restricted by clearance for drills / rivet tools:
We used a 90-degree drill bit extension to drill the rivet holes for the supplied mounts
We mounted the supplied upper radiator mounts in the middle of the front frame square member so we could gain enough clearance to drill the holes, install rivets, and install the fastener to hold the radiator
This required us to design and fabricate mount extensions on the radiator to reach the mounting points on the frame, this also required us to modify the radiator to install these mount extensions
The radiator placement is dictated by the intake and upper radiator hose location, on the 1.8L intake the upper radiator hose will contact the intake with the radiator closer in the car - mounting the radiator in any other location than where the upper hose clears the intake will result in non-assembly and you will have to redo all of your radiator mounting
One of the most tedious parts of this process was mounting the radiator, it must be located in a specific way and failure to do so will cause other assembly problems in the future - it is highly recommended you chose an aftermarket radiator and use this to start as you may create more work for yourself in the future if you reuse the OEM parts
The frame clearance to the shock mounting point is minimal on the Exocet frame:
While it is stated by Exomotive that NA style shock top mounts (top hats) fit, ours did not at the front - there may be variation in aftermarket mounts that cause slight interference with the upper tube member
We had to use NB style shock top mounts that came with our Flyin' Miata V-Maxx coilovers
The Exomotive shock spacers require modification to install:
Some of the fastener holes butt up to weld beads, we ground corners off weld beads to make clearance for the bolt heads
The rear spacers cannot be assembled without cutting fasteners down in length, careful trial and measurement is needed to cut just enough off without going too short
Bolts need to be inserted into the rear spacers before placing them on the frame or installing the shock, otherwise there is not enough clearance to install them

General Information:
Sizing Drill Bits for Rivet Nuts:
The drill diameter is equivalent to the OD of the rivet nut
Different material rivet nuts can have different OD
Round to the nearest whole number
Use the rough equivalent English drill bit - actual metric bits are hard to source and horrendously expensive if bought in a set
Metric drill bits can be bought individually with a tap or as part of a tap and die set; the extra precision is not necessary for rivet nuts
M5 --> 7mm OD ~=1/4" Drill Bit (5/16" was used, 1/4" was undersized)
M6 --> 9mm OD ~=23/64" (5/16" undersized to 3/8" oversized) (3/8" used)
M8 --> 10.9mm OD rounded to 11mm ~=7/16" (not used at this time)
7/32" Drill Bit used to open up 3/16" P-Clips for M5 Fasteners / Rivets
