Dear All, Since I had my last TB job with the motor out, sometimes when I start my car (91, MT) with the hand brake engaged, I get the 2 red brake lights on. If I drive, then I get ALB and TCS. If I start my car without the hand brake engaged this never happens and no lights coming when driving...

Dear All, I did not find a real answer to this problem. My clock and AC/ventilation have a very low intensity. I think this is a matter of time that they become darker and darker. How can we get them brighter again ? Are there bulbs in the clock and AC modules ? Will new bulbs help recover a...

I realize that I never made a proper post here. So let's talk about my girls. '92 Track Tool I bought the car in 2005. It only had 19'000 km (12 kmiles). Now it has 50 kmiles. Drove it 4 years on the street and a bit on the track till I decided to make it my track tool. I decided not to go...

Dear All, While doing the VVIS delete, I want to clean my injectors. What gaskets should I replace ? Number 17 & 2 ? https://www.oemacuraparts.com/v-1991-acura-nsx--base--3-0l-v6-gas/engine--fuel-injector-1 Something else special while doing this job ?

Dear All, What to think about this new VVIS delete kit from SoS ? Always heard that deleting the VVIS would affect the torque under 4krpm. The result here seems different. Go or no go ?

Because of some play on the lower ball joints, I replaced my rear knuckles by used (but good) ones. So now I have my original knuckles that I can service. What rear lower ball joints do you recommend (track car with slicks) ? I saw that Carbon 6, Hardrace and Pride do provide replacement. Who...

On my track NSX, I am now running 215/615 R 17 slick tires on 17x8 ET40. I have -3.5° camber and no liners. No rubbing except a bit at full lock at the fenderwell (normal with 615 mm diameter). What if I go with 20mm wider fenders like the Garage Kite ? My goal is to go with the next bigger...

I did not found any clear information but I saw some posts from Honcho saying that it is possible to reprogram the 91-94 ECU. I think this is a "budget" way to have a good map on lightly modified cars without going to the hardcore Ecutek or AEM. A friend of mine did reprog his track S2000 (only...

I don't know how to call them exactly : "solid", "spherical", "non-compliance"... I would like to replace them all. I already have the non compliance rear beam bushings and toe links. That means there are still 5 each side to replace (front upper and lower, rear upper arm front, rear upper arm...

Dear All, Who is still making wide front fenders ? I mean (close to) OEM looking but a bit wider. I think of Garage Kite that we can get from Mita, but who else with a bit of availability ? I am now running Hankook F200 215/615 R17 front on 17x8 ET40 wheels and 3.5 ° camber without splash...

Dear All, I am starting to collect the parts for JDM short gears. Countershaft, 3rd and 4th short gears seems to be available (Amayama or Christian at ATR Racing). The problem is the 2nd gear (23431-PR8-010). Discontinued from months (Amayama gives a wacky delivery date that shows they do not...

Does one of you run slick tires ? It seems that I am always lacking a bit of temperature at the front tires compared to the rear ones that are really at the right temperature. It is a bit better when outside and track temp is very high in a good summer day, but otherwise it is a bit annoying. I...

Dear All, As I have an EUDM, I have the switches for fog lights in the center console. I want to be able to turn the front fog lights on while the headlights, the rear lights and the instrument / gauge cluster lights are off. If I come with 12 v accessories to the fog light switch in the...

I have an Odyssey PC680 on my track car that I use 5 - 6 times per year. Rest of the time, I have a Ctek connected. But when I try to crank, the battery is not charged enough and it is too weak to start the car. After a 20 min track session, it is ok and enough charged to start the car. But not...

I am reading some previous posts but perhaps you can help me resume. I can have an AP2 S2000 steering wheel for cheap. What is the stuff and adaptators needed to install it on my '91 ? Without srs lights coming on and a functional airbag...

I am now running stock 16 / 17 with 15 / 30 spacers and AD08. Really like the ride with small wheels and good tires. Far enough grip for the street rides and lively feel. As I have a set of stock 15 / 16, I was planning to try them next summer. With spacers too (20 / 40 perhaps). But I have...

Simple question : is it mandatory to remove the head covers (and then replace the head cover gaskets) to replace the timing belt ? I am asking that, because my two NSXs do not make a lot of miles between two timing belt replacements and are stored in a dry heated place. So I do not want to make...

Could you confîrm the list below ? 23210-PR8-020 main shaft 23441-PR8-020 3rd gear for mainshaft 23451-PR8-010 4th gear for mainshaft 23581-PR8-020 5th gear for mainshaft 23431-PR8-010 2nd gear (1.952) for countershaft 23471-PR8-000 3rd gear (1.400) for countershaft 23481-PR8-000 4th gear...

At bearable price : SoS, Vis, Seibon ? I am not looking for the ultimate fit, as it is for a track car and not for a garage queen. But I do not want 1/2'' gaps as well.

Fake Denso spark plugs from "directautoparts" at 100$ for 12 pieces ? Installed these plugs. Car ran on 2 cylinders in the front raw. Drove with the problem. Spark plug n°6 was darker. Changed the spark plug with a 20 $ one from my Honda dealer. It solved the problem ! After 50 more miles, it...

My fuel pump resistor becomes hot like hell ! Normal or defective ? I ask because I have this power loss between 3500 and 4200 - 4300 rpm that disapears when I bypass the fuel pump resistor (explained in my last thread). And I realised that it becomes hot like hell when it is connected...

I have a slight loss of power between 3500 and 4000 - 4500 rpm. This results to a kind of power jump, like a (very) mini vtec kicking in at 4000 - 4500 rpm. Well, I feel it because I am a psychopath and I know my car. But anyone else would not even feel it and be upset by this. As this is the...

I would like to share on the resolution of my problem on my '91 : - intermitent hesitation, bogging / delay when accelerating slightly (less than half throttle) at low rpm (under 4 krpm) - no cel - no problem under hard acceleration (more than half throttle) - problem disapeared when...

I did not find a post that gather track vids. I beginn with the one of my last trackday in France.

Before my last track day, I had to change the rear left wheel bearing. Normal as I had 6k track miles on this original bearing with slick tires. After this last trackday, I realized that the right one was also going wrong. So I changed it recently. I check this new bearing and realized that...
