MX5 Fun Car – Engine and Engine Bay Prep

Planning on getting the engine in this weekend, so had a bit of work to do in order to get it ready for installation. First up was to get the sump on with plenty of loctite inside:

Then a new 36-2 timing trigger wheel from Beavis:

And crank pulley with fresh timing marks:

Test fit the new injectors for ease of fitment before the engine goes in. Went with Bosch 960cc long nose injectors with adapters for full length, instead of the RX7 injectors i had for it:

Installed on a nice bit of bling that will be summarily hidden once the intake goes on, a Radium fuel rail:

I was originally going to use a factory rail, but they were thin on the ground and the few people who had them wanted more for them than the Radium… a bit ridiculous.

Then it was time to add the 1/8 BSPT oil feed fitting which worked perfectly… amazing what 5°of taper difference will do:

After that I turned to the engine bay, and finished off fitting up the fully depowered NB8B rack, now that the urethane bushings had arrived:

Afterwards I figured I may as well hack a massive hole in the firewall, freehand using the diegrinder.

Now enough space for the new wiring loom grommet:

Also figured out where the Flex Fuel sensor is going to live:

And the bling catch can arrived. Big enough for CAMS specs:

Finally, I replaced the input and output seals in the gearbox:

And cut the expansion joints into the turbo manifold:

All pretty much ready to get bolted into the car on the weekend, just need to mount the engine to the subframe, attach flywheel, clutch and gearbox and then roll into place.

Oh and as a bonus, this is why cheap eBay parts often bite you in the butt. Oil filter relocation adapter, nice AN10 fittings. Right… wrong:

They neck down to 3/8″ thread, and internally the wall thickness restricts flow immensely:

In my case I’ll drill and tap them to full AN10, but if you don’t have the gear, or didn’t check it that would be an immense restriction.
