Billy Johnson and Moto IQ's: Project NSX

The next installment of Project NSX is live!

Project NSX Part 19 – Designing a Crank Position Sensor and Knock Control​

We design a custom tone ring and hall-effect sensor mount for our Motec M150 to more accurately record the crankshaft position and control ignition timing at high RPM. We also upgrade to a wideband knock sensor for a better failsafe against knock.

Whenever the next article in this series comes out I always end up reading the previous 1-2 just to remember where they were in the build.

They are such a great shop.

Project NSX Part 20 – Antigravity Lithium Battery and CTEK Charger​

When it comes to weight reduction, it’s difficult to beat the cost-to-benefit ratio of a lithium battery. We replaced our NSX’s heavy AGM battery with Antigravity’s drop-in Group-35/Q85 lithium battery and keep it in top form with the CTEK lithium charger.

Based on a post I noticed on social media yesterday, I'm sadly suspicious that this great NSX has been damaged quite badly. I certainly hope not!

Yeah I saw it too. It looks bad, but repairable. Maybe a MotoIQ article on a proper NSX chassis repair job versus the scary cut and paste jobs we see?

That would be pretty nice to see, I'll admit!

Rumor has it, he already has purchased another car and will be moving all those fun parts to it.

Nice! Hope to see the car back in action even if it's a different base shell! Always appreciated these articles and updates on the project as little inspirations.

It's been a while, but Project NSX is back and the next installment is live!

Project NSX Part: 21 - Foundry K-Coil Swap​

With forced induction on the horizon, we upgrade the spark energy for our C30A engine with the Foundry 3 K-Coil Swap Kit:

These modifications clearly bring the NSX NA1 in the 21st Century.
Congratulations

I'm already forward to some new Buttonwillow lap times from @stuntman

It might be worth checking the crimps on the foundry 3 coil harness before you get everything together. My foundry 3 k coil harness fell apart at the igniter connector and caused a lot of weird behavior that was hard to track down. The wires (22awg) fell out of the terminals as the hw 090 terminals are made for larger wire. If it were me, I’d probably go through and re crimp all the terminals. I ended up building my own harness

Hi Billy, in the NSX project series do you plan to address the power assisted steering possibilities?
I'm well aware of the S2000 and derivatives that are available but I was wondering if the system used on the Alpine A 110 could be an option? The Alpine A 110 is in a way the successor of the NSX NA1in my view.
I found a parts list here FYI

I thought about something similar; I just have not looked into if there is room under the dash to fit an inline steering assist. I'm also not a huge fan of EPAS and have an idea for a hydraulic rack that I would like to do at some point, which should give the best power assisted FEEL (far better than EPAS).
