We've recently taken in an F40 for some diagnostics, repairs, and upgrades. The car was brought to us with some significant drivability issues. Keep in mind this is no ordinary (is there such a thing) F40, it has twin Garrett GT3071R's with TiAL housings, custom headers, a built motor, and most of the supporting mods (more to come).
The first issue we came across was an ignition miss caused by faulty wiring. To solve this we've decided to rebuild the entire ignition harness utilizing an M&W Pro-18d, and 8 Denso pencil coils.
We'll keep the updates coming but meanwhile here are a few more pics...
Don't worry it's getting a new splitter.

We're currently doing a valve adjustment and will soon be putting some new injectors in.
