+1 on the fuel pump resistor bypass check. Had the same issue. It got way worse when I installed the new headers which obviously makes the engine produce more power than with the boat anchor headers. Therefor it has more fuel demand, especially at lower rpm where the headers really make a...

Yes, especially in your application with the stronger than stock fuel pump. The stock fuel system is definitely not ready for flow rates way higher than it was designed for. Maybe I will buy a pressure gauge and do a test. Hook up the resistor again and see what pressure I get at idle and what...

The fuel lines on the NSX are fairly short and standard size. Don't see why this would cause issues. Bernhard

O2 sensor related hesitation feels different. Its more like misfire, like messing up with the clutch on acceleration, when it feels like riding a bull. Also only happens after cruising oder while cruising because the 02 sensors need temperature to work. The fuel pressure hesitation is more...

I have too much fuel pressure at idle with the weak stock fuel pump running at full speed as it runs rich at idle. I have seen that while doing the emissions test. So the regulator is too small. No idea how the stock fuel pressure regulator would manage the extra flow of the stronger walbro...

I haven't found it in the service manual. Does anyone know the resistance of the resistor box? It is absolutely possible that the resistor box suffers from vibration but most likely it will either fail completely or have extremely high resistance making the car undriveable. Other thing to...

why should the resistor go bad? That's a solid part. The pump surely wears after 200+tkm and 25 years. An interesting temporary fix would be to find/build a replacement resistor with half or 2/3 of the original resistance. Bernhard

I ran the complete season this year with the bypassed resistor. No issues from a driving point of view. BUT i had issues passing the yearly emissions tests. The engine is running too rich at idle with the resistor bypassed even with a weak fuel pump. That's also what LarryB on prime says...

Those BC Coilovers are the same as D2 and KSport. It should be screwed into the lower cup at least 1". Preload must be determined by installing it and measuring how much the damper is compressed by the weight of the car. There should always be preload on the spring. The damper should be...

on the second picture, the left bolt looks strange. Why is that not centered? Post the printout of the allignment. Most of the time they mess up something they than blame some random part for. If the car is properly alligned, the steering wheel points straight. I had one bent rim on my...

I had issues with the emission test last week. Car was running a little rich. Did not reach lambda 1 and therefore also not got below 80ppm HC. I have the fuel pump resistor bypassed because the fuel pump is a bit week after about 170k miles. I think this is the reason for that. The fuel...

Sad I did not have time to visit ... Cool results. Exactly what everyone who knows Honda engines always tells you ... OEM Airbox is best, even with engine mods. I believe the difference between the airboxes would be less with a stock engine though. Bernhard

19501-PR7-A00 DESCRIPTION: HOSE, FR. WATER - DISCONTINUED 19519-PR7-A00 DESCRIPTION: HOSE, WATER MIDDLE - BACKORDER (RELEASE 10/6) My car is first registered early 92 but definitly built more like early 91 as it does not have power steering. Bernhard

I tried ordering all the hoses ... one is discontinued and one on backorder for longer period of time. I hope that is just a temporary situation :( Bernhard

Thanks for your "guide"!!! I did the install 2 days ago and it would have been a lot more complicated without reading your post before. Bernhard
