When my engine was getting repaired, I ordered the printed books, How to Rebuild Your Nissan & Datsun OHC Engine, and How to Modify Your Nissan and Datsun OHC Engine. while reading the descriptions of the books, I discovered that they were also available for the Kindle program, so I got the first book in digital form. I like having digital versions of books or documents because the computer can quickly search for a word or phrase, and you can store many, many books on even the smallest of flash drives or a CD or DVD. I still appreciate having printed books because you have the pleasure of browsing the pages without the limitations of screen resolution, batter…

I've got my E88 apart now and cleaning, polishing everything. My cam lobes are nice and smooth just not shiny like I feel like it should be. Sorta dull grey, but smooth as butter. Should I polish them to a shinier finish? Does shiny mean worn? Thanks Cliff

I recently was contacted by a garage in need of the Distributor mount as seen at the top of my avatar. If you have one to sell PM me and I will put you in touch with the buyer. Thanks Ed

I'm wondering if the valves rotate under tension while the motor is running. I had a leaky intake valve, turned it 180 degrees and now it's tightly sealing. When I put that head back in use will that valve possibly rotate in relation to the valve seat? Thanks

Hey gang, I just found a broken front diff mount today on my race car, so rather than destroy another stock mount I thought I would install the RT mount by Techno Versions. I did a search, but couldn't find a definitive answer on whether or not to include the Energy Suspension mount or not. I saw a thread a while back about added vibrations due to a different driveshaft angle, but there was no follow-up stating if the mount was the issue. I have to get the car back together soon as I have a race coming up in a few weeks. Can the poly top-down mount be modified, or should I just order an OEM mount and the RT mount with the snubber? http://www.technoversions.com/Di…

I think these are just emissions parts. I am about ready to take them off, but want to be sure. I have looked them up in my how to restore your 240Z book, but they give little more than a name. I honestly do not see what their purpose is at this point. Perhaps they had something to do with some form of emissions equipment? The guys at hybrid Z said it has something to do with idle control? Any help would be great.

Hi everyone, I am in the final stages of a complete rebuild of my 72 Z. 133 thousand miles on the odo. Transmission is complete, head done with a midly agressive cam, block refinished and bored to .030, crank polished, ground and balanced. I had ordered a "complete" engine kit including fuel, oil water pump, all gaskets pistons, rings. This kit was ordered from a well known z car parts supplier. I received the kit and a thourough inspection by me and my trusted mechanic exposed the following issues: 1. Head gasket was too thick and did not fit correctly. 2. Pistons were ITM make and skirts ( bottom) was 0.5-1mm wider than the piston head. They were also 26-30 g…

I've got a 76 280z 2+2 with EFI that I've been "refreshing" over the past couple of years. Everything is pretty much stock. I've just recently been taking some test drives and as mentioned it seemed to be running great. Then on the way home after turning off on a side street at about 20 mph it just died. It happened so fast I'm not even sure how to describe it. It's kind of like it lost all power or else its like the new fuel pump I recently put in quit or ... Like I mentioned, it happened so fast I'm not sure what happened. So I coasted to the side of the road and when I tried to start it, it fired right up. So I continued heading home, which was only about 1 mile away, …

Hi guys, I recently picked up a 3.1L stroker for the Z that I'm going to swap into it in the next couple months and was hoping for an opinion on clutch choices. I actually already have two: a six puck clutch and a centerforce clutch. I got both of them with the engine and a 5 speed. I'm looking to maintain streetability through this evolution but I'm not sure which one is the best way to go and was hoping for opinions. Again, I have both of them brand new already so whichever one I don't use I'm just going to sell off anyway. Thoughts and opinions are very much appreciated! Thanks! Chris

Just replaced my fusible link yesterday, which was kindly sent to me by Michael Mcginnis at Banzai Motorworks. The male connector was not bad, so i just cleaned it with a brass brush wire and replace the plastic Shell. The female which is attached to the starter was fully replaced as it appeared to have taken a lot of heat. Anyway, while craking the car out of the parking in reverse and sliding 1st, i did notice the car coughs and presents a slight hesitation. Not as it used to before, but still some hesitation. Is this normal when the car is cold? I have deleted all of the emission crap on top and asides of the balance tube. Could this be cause of this coughing and low…

Is there anything else than the Spectre Performance cone filters that you can use on the rocker box? The biggest one in the AP stores only has a 10 or 13mm neck, and the tube on the top of the rocker box has an 18mm (3/4 inch) tube. I thought a small diameter inline filter would be better than a 2 inch cone, and I don't like piping the oil blow-by into the intake manifold Check the lawn mower or cycle shop maybe? thxZ

I was advised to have the driveshaft (propeller shaft) balanced after putting new U-joints, which is scheduled to happen this week. There's a new vibration last few weeks that may or not have to do with the U-joints. No vibration previously, and the driveshaft hasn't been altered or dropped, so balancing seems unnecessary to me. But maybe I'm wrong.
