damper doc

I thought I would follow up on my damper pulley saga. I had to find a newdamper pulley for my 240z since the integrity of mine was in question.My options I found out was to buy another used one that the rubber was probably shot or buy an after market race pulley for a couple hundred.I found this damper doc guy out in california that rebuilds dampers for all vehicles.It cost as much as buying a used one , and he about guaranteed it against failure. I asked him if it would hold up under slightly higher then stock rpms and he said he would only worry about torque issues. And he was talking big block torque values. He charged me 69.95 for the rebuild which I thought was reson…

Ok, yell if you've experienced this yourself: Whenever the engine is under extreme load in upper RPM, it begins to cough and stumble. Power literally drops as if falling off a cliff. It began shortly after I tuned my SU's and advanced the ignition from 10 init 32 adv. to 13 init 36 adv. I don't believe its the carbs, as the car is running stronger than ever before (until X rpm, as stated below). I tested for detonation by putting the car in 3rd, and pulling as hard as possible up a hill from 1800 RPM. No pinging or knocking. Just a complete lack of power at roughly 5500+ in 2nd, 4600 in 3rd, 4200 in 4th and 3500 in 5th.

Got the thing to crank and start up with some gas-in-a-can. but it won't sustain itself so thinking it's the fuel pump. Where is this thing located? This is my first Z. It's been sitting at my cousins farm for about 6 months. now there's a bunch of snow around it. Trying to decide if I can fix it at where it is or if I need to tow it home (abut 25 miles away) Thanks in advance. -Chee Forgot to mention it's a '72 240Z.

Anyone have an idea of what a fair cost is of an original, used 4spd transmission setup in good working condition? What's the best non-eBay place to get it? Looks like I'll FINALLY be purchasing my Z later this week after a very long search It's an auto and I'm seriously considering the switch. Aside from changing the Z from its original factory specs, are there any other issues/drawbacks to go along with the switch? Is the transmission code even located on any of the data plates? Aside from some aftermarket seat upholstery, the car is basically bone stock. Mike

I just purchased a set of 8mm 240 rods for my new engine. The rods have been lightened and have had ARP bolts installed. What is the proper torque for these rod bolts? They are 8mm.

My Z car has been doing this for a while now, but i have been busy with other more necessary problems to really worry about it. For some reason, If I am approching a stop, and the car is warm, the moment i put in the clutch, the engine will go up to 3k RPM and will hold there until the car comes to a stop. If I am driving and the engine is cold, it won't do this. This really bugs me and i think is one of the factors of my 15Mpg fuel economy. I would be greatful for any help in fixing this problem or for ways to impove my gas mileage. This is a 77' 280Z.

I have a 7-71 240 with a 3 hole upper thermostat housing. Is this correct? Do you have a 2 or 3 and what is the production date? Note sure what the extra hole is used for, since one of the other holes holds on the sparkplug wire loom. My lower housing only has 2 holes. Thanks Keith

[B]who can help me?[/b] I have a 1971 240z. I had to bore it three over and I had to deck the block two down.In the block I have flat top pistons. I'm also installing 280Z vales in my E31 head. And I plan on putting a header on also. Other than that every thing is stock and I plan on keeping it that way. So what cam do you advise me to get. MSA's third package sparks my intrest but some say that it will make you slugish out of the hole. But a guy at MSA tolled me to get six pounds shaved off my fly wheel and it will fix the problem, is this true and how much will it help. I'm not looking to make a total race car, but just Excellent street performance. And I am also wounde…
