Yep the vibration is felt through the car. I have sort of developed a technique to minimize the shudder on takeoff: rev to 1500rpm and swiftly release clutch as revs drop a bit before full engagement. Feathering the clutch while manoeuvering the car in parking lots or driving in trafic will...

As an update, I performed the procedure with center mount bolts as explained above. The result is that shudder remains but mounts do a better job of reducing the transmission of the vibration to the chassis. For me this is not satisfactory. As a side note, I noticed that engaging first gear...

Thanks. What size tapered punch would be appropriate to attempt the alignment job?

The 1997-2005 WSM shows that a tapered punch should be used to align the subframe to body. Anybody has performed the alignment, if so what did you use?

Thanks Honcho. My only concern about not supporting the engine is the right side mount which has, contrary to the other 3 mounts, a vertical center bolt. Also I had previously understood that once center bolts are loose the engine had to be manoeuvred up/down so that the rear mount bolt is...

I knew that incorrect motor mount torque sequence could result in excessive and uncontrolled drivetrain movement. In fairness, the WSM isn't clear about the proper sequence, but it states that noise and vibration can result. However I was under the impression that only the 3.0 twin disc clutch...

Anybody with the body supplement to the WSM can tell me what's the part number for the rear subframe alignment pins? I think it is 070AG-SJAA10S but I'd rather be sure.

Update: I had the car put up on the lift to inspect through the clutch case cover. Using a boroscope camera fitted between the flywheel and the case, I confirmed that all 3 guide pins are where they should be in terms of clearance as shown in the manual, and that the wave washer disc is on the...

Thanks everyone. The Honda urea grease was used, I'll enquire with the mechanic about how much was used. If he remembers. With regards to the input shaft bearing, it was replaced along with other angular bearings (5 in total) in the transmission. Are we on to something here? I found out that...

Sure is possible, but quoting LarryB: Did you initialize the clutch? If not, start there, if it is not initialized it will not disengage, and not go into gear..... No such problem here, goes in/out of gear normally.

My 1991 had its first clutch change last year at 92K miles. Although it didn't slip, a slight vibration at the bite point in first gear was diagnosed as a worn flywheel, and frequent resistance in getting the shift lever out of gear was a sign of clutch trouble to come. The time was right to go...

Looking for intermediate shaft, mostly interested in 2 support pieces in good shape, but will take whole assembly. Thanks!

Anybody knows the difference between the NA1 and NA2 brake boosters? I see different numbers for 91-96 and 97-05 (cutoff is not 2000 so I assume ABS is not part of the equation). NA1 booster: 46400SL0951NA2 booster: 46400SL0J02

I understand this may change in the coming days as websites are updated, but so far I'm releived to see only minor increases of 1-3%. If the rumored hikes turn out to be much smaller, it will be excellent news for all of us.

Does anyone know whether the different versions of the Comptech headers for 3.0 and 3.2 are different designs or the 3.0 application is the same as the 3.2 + extensions? If so, are these extensions still available? I can't seem to find info on the CT engineering website. Thanks,

I may point out that the TB job that resulted in the loose belt was done with the engine OUT. The Audi mechanic who fixed the timing and tensioned the belt properly did it with the engine IN. That's how I feel. The Audi technician figured out the problem within an hour and upon hearing the...

Timing marks were double checked before re-assembly, the whole operation of getting to the TB, setting tension and reassembly took about 5 hours. The Audi tech said I was one monkey shift at high RPM away from jumping a couple teeth wrecking the engine. In fact, when bringing the car to him for...

PROBLEM SOLVED. As a followup to this thread of mine, it could be of use for the community to know what caused this odd noise. It was an insanely loose timing belt. https://youtu.be/43l2Ur4epRI To recap, I had the TB/WP service done late last summer and the car was returned to me producing...

Nissan and now Toyota are putting some parts back into production for its older Skyline and Supra models, any indication that Honda intends to do the same or, at least, maintain its current offer of available parts? It is a concern of mine that our cars will become more and more difficult to...

Gotcha. Sound clip starts on the airbox side, halfway through moves to the belt side. Apparent consensus on bearing noise, the mechanic who inspected the car when it was brought back to him to investigate the noise said bearings (alternator and ac tensioner) were looked at before reassembly and...

Thanks for taking a listen, but it should be approached as a sound file, not a video. I'm documenting a noise, visually it's no different than any other NSX motor, and like I said, the noise is heard strictly at idle, a rev blip no matter how small will kill the noise. TB tensioner too tight is...

SOLVED: Chasing strange whine This is sort of a repost which I had initially suspected to be associated with VVIS, a strange whine or drone noise coming from the engine bay at idle (even the slightest increase in RPM kills it) when the engine has been fully warmed up (sound clip is posted...

Kaz, thank you! The borescope test is really easy to perform and highly recommended to all owners now that these devices are very cheap to buy online. Took me the best of 20 minutes to remove the top of the airbox, run the borescope taking pictures of all 6 flaps, and reinstall everything...

My car developed a strange and fairly loud drone like noise at idle after the major 90,000 mile service (which did not include pulling the VVIS assembly to inspect screws, I found out only recently that it was an area of concern), the mechanic who performed the work inspected the alternator and...

I'm actually looking at swaping in the whole NA2 setup (headers, cats and muffler), hence my question regarding the clearance of the 91 sway bar. I remain unclear about this. Thanks for pointing out the 2 secondary o2 sensors are not found on my 91. I suppose these plug into the NA2 cats and...
