MX5 – Supercharger Build Finished

I think it might be finished or at least as finished as any project can be.

I had a bit of a move around of gauges inside. I found having the wideband gauge low down a bit of a problem when trying to catch a look at it to keep an eye on fueling while mapping or just generally making sure things are running ok.

The silver bezel on the gauge I had from the Evo didn’t fit in the rest of the interior so it’s now black.

How things look now. Β Keeping an eye on fueling is much easier now.

I also painted the radiator cowl black to help give it a bit more of a clean factory look. I’m not really into having loads of shiny bits in an engine bay.

Finally, a whole load of pictures of it as it looks now. They may be useful to anyone, looking to do a similar build, in figuring out the layout and position of things.

One way valve added to the PCV to prevent boost going into the crank case.

Well that’s it. So far so good. Well pleased with how well it’s working. It starts perfectly hot or cold, idles happily with no stalling but best of all it really pulls pretty well. It may not be as quick as the Evo but it’s definitely a bit of a machine and gets down the road well when the tyres hook up. It’s also nice having the instant throttle response with a bit of grunt behind it, no having to wait for turbo boost to build.
