Driving that thing for daily activities must be such a treat!
Honcho's Long Road to Imola Type-S Zero
- Thread starter Honcho
- Start date
It's like having a new NSX in 2024.
Thank you!This is an inspiring build! Congras.
I can't wait to collect mine in two weeks, Hopefully
Summer Wash/Detail 1
The Zero has been getting heavy use this summer. With the wet weather in the spring, we had a lot more dust and pollen than normal. This has all combined to make the car filthy. Time for a wash. What I've found with the PPF and the sealant is that you don't need to scrub the car at all. I pre-rinse, hit it with the foam cannon and then rinse off. This lifts all the grit and dust off the car.
Gotta love the Imola.
The engine bay and the front compartment also were covered in road dust. I find the same trick works here. Foam cannon and then a rinse with low pressure water on the "shower" setting on the nozzle. No pressure washer in here! All the dust and grit just rinses off.

Wow - no electrical issues thereafter?
Next time you should protect -at least- the fuse boxes and battery somewhat, I think.
Anyway - GREAT car!
The frunk is exposed to copious amounts of water every time you drive in the rain (I know I know NSX owners are afraid their cars will melt in the rain) and the car is designed to handle it. Washing it isn't going to hurt anything lol.
Apart from this bad design (but not dramatic) ...
... I think you're right.
No, never. The electrical connectors in the front compartment are the HW-series Sumitomo. These connectors use a rubber seal to keep moisture out of the pins. Like John said, the area sees a lot of water when driving in rain and is designed to get very wet. Still, if you do this, use low pressure water (no pressure washer) and the "shower" setting on your hose. Also, be smart and don't do dumb things like blast the fuse boxes up close LOL.
I do the same thing to the engine compartment.
Summer Wash/Detail 2
After a quick dry with the leaf blower, back in under the lights.
The foam gun/gentle rinse method works really well to keep the road grime down if you do it once or twice a year. Here is the front bay after a wipe down of the black bits with 303 and the painted parts with detail spray.
Same deal for the engine compartment. It always turns out really nice with minimal scrubbing. The leaf blower is key to removing most of the water.
The underside of the hood had some grit from rain driving a few times. I try to avoid it, but Colorado weather...
Last step before tackling the interior is to wipe out and clean the side sills.
Even though I have the fresh air filter, I run with the windows down in the morning when it's cool. I like to listen to the exhaust note. This introduces dust into the cabin, unfortunately. Here's 6 months of grit.
Floor mats were also dirty. You can see the heel impressions from all the driving and heel/toe LOL. I've got a surprise plan for these...stay tuned.

Restoration Loose Ends
While detailing the front bay, I noticed these issues.
The radiator coolant aluminum section is making contact the the body. Honestly not sure if this is normal. The pipe is rigid so perhaps there is no danger of rubbing damage. Also, if I add a spacer to the front bolt, it will throw off the alignment of the bolt on the firewall. I'll need to investigate further.
Also, the NSX-R sway bar is contacting the radiator lower hose. I re-aligned the bar last fall, but it has apparently shifted left about 10-15mm. There is thankfully no damage to the hose or clamp, but I will raise the car and re-adjust. @Kaz-kzukNA1 is this normal for the NSX-R bar?

Intake Modification 2
Last fall, I modified the air induction system to increase (hopefully) the CFM of the intake tract. My idea was inspired by Honda's design for the NA2 and I hoped it could feed more air to my Comptech-powered 3.0L in the same way. I took the car to a Honda/Acura cars & coffee this morning and it was a good opportunity to do some logging. I'm pleased to report there was a result.
If we look at a log from last August, the stock intake system delivers a load factor of 74% at 5,952 RPM and WOT. This means with the throttle butterfly fully open, the most air the NSX can cram into the intake manifold is 74% of standard atmospheric pressure (14.7 psi), or 10.9 psi. The blue line is load, which is essentially manifold pressure on the NSX ECU. Green line is throttle position and orange line is RPM.
As the engine runs up to 8,000 RPM, the load falls to 71%, or 10.4 psi.
After modifying the intake, the car still makes 74% at max load- that's really just a function of our altitude here (6,000 ft).
But now, the pressure in the intake manifold falls to 72% (10.6 psi), an improvement of 1%. This result was repeated over and over in the log. I'm not sure how many horsepower 0.2 psi of "boost" equates to, but it's probably around 3-5 hp. Also nice is that since the slope of the line changed, the car is making more power across the powerband- not just at max RPM. In any event, it seems this mod, which cost me less than $50, was worthwhile. After all, on a NA NSX, every little hp counts!
Now, would this work for an otherwise stock NSX 3.0? I doubt it. My car has a modified exhaust tract, 36mm intake valves and high-lift camshafts. It's designed to move more air than a stock car. If you have a 3.2, it's worth considering though.

Great reporting on the extensive work you've done to the car!
