240ZX

Thank you Bruce! You are so right. When are these people going to learn that we just want the truth.........not hipe and BS. One of my favorite sayings is....."It's mind over matter! But, if you have no mind then it doesn't really matter!!!"ROFL ROFL ROFL ROFL ROFL

I had the same issue with my Z. However, at the time it had mucho miles on it and the throttle linkage was pretty loose, well used at best! I read articles that described the problem and some even went to the extent of fabricating and or modifying the existing set-up. Well, that is what I had in mind at the time too! But, here is what I did and it works smooth as butter now. First off I went about eliminating the excessive tolerances that occured from 30+ years of use in the linkage. Secondly, I adjusted the adjustable part of the linkage to minimize the camming effect (hard to push initially and then it get's easier all of a sudden) to a minimum. And thirdly, I replaced the two return springs with a pair of lighter Stainless steel springs. Of course I did some testing to make sure they were not too light! I now have a throttle that works smoothly and with good control. In addition, I attribute some of the smoother take offs to the addition of a 13 1/2 lbs flywheel......which originally everyone said was a bad idea for the street because it would be hard to drive!!??!!?? Well, the truth is that it actually drives much easier with the light flywheel than with the stock unit.......go figure!? Just one man's opinion................that works!

Landmizzle is right on the money with his explaination of premium fuels. As he said, the additives (antiknock agents) prevent the fuel/air mixture from igniting prematurely. And yes, premium fuel has less BTUs per give amount of fuel. So, as it has been said many times before....is it's not pinging and your using regular grade fuel, everything is fine! Using a higher grade fuel is a waiste of $$$

I just think it's funny as all get out, that the spark plug marketing people have lead the consumer to beleive that spilfire, V-tip, and other multi-electrode plugs are better than the single electrode plugs for performance.......wow!!!! If one electrode works good then two or more are going to really improve my performance!!!! The only performance improvement that you will get is from weight lose..........less weight in your wallet that is, because now the plug manufacture has your hard earned $$$!!! P.S. Sheep are always going to follow......................

Hey Victor, You can imagine I was confussed, at first, when I installed my late model 5 spd, because every article I read said........"They just bolt right in without any mods!!!". Can you see me saying....Yah right!!? Of course later on I discovered that the later 240s did not require the mods. Live and learn! Anyway, with the 5 spd, 3.90 diff, and my 235-40x17s my Z accelorates very nicely concidering my L6 (2.8 litre) is internally stock.

I put a late model 5 speed (shorter in length than original 4 spd)in my 1970 and it required trimming a little off the front of the tunnel opening, in addition to a modified shifter. This may be specific to the very early 240s as it seems the later 240s do not have the same clearance problem. I'm not sure now accurite this info is but I did have to mod my tunnel and shifter for a proper install.

If you are considering 17s, that'll work! I've seen a number of guys who are running 225-45x17 fr & 245-45x17 rear with no rubbing issues. I am running 215-40x17" on 8" wide wheels (fr) and 235-40x17" on 9" wide wheels (rear). However, I've also got sectioned struts w/ coilovers and wheel spacers. I think your choice, 17"x7" wheels, is just fine and you will likely have no problems. Hope this info helps?!!

Wishihada240, The Z Police have done it again..........saved another brother from waisting him hard earned $$$. Isn't it just the coolest think to have all this expertise on tap??? Good luck and good hunting! Everyone deserves a hand

You might want to go to HybridZ. I frequent the site often and it has lots of tech advise on engine swaps. Ok guys....don't panic, just because I frequent the other guys' site doesn't mean I'm thinking of replacing my L6 in my 240!!!

Hate to break the news to you but, from the pics you posted and the exlanations about the other areas.................this Z has a severe case of the old rust monster. You can bet that if it looks that bag externally, it is likely even worse internally where you can't see. IMO, the $900.00 you sent this guy to hold the car is probably more than it's worth to begin with. Just be advised, if you purchase the car, you are looking at some serious time and $$$ to get the car in rust free condition. Don't let your emotions make your purchase decision. Just my opinion and an attempt to save you some heart ache later on. Stay focused and keep looking.....they're out there and in better condition for $2K

Sounds to me as though you are a prime canidate for learning about basic engine tune-ups and such!!! You have to understand that the question you pose is sooooooooo general that it's just impossible to provide you a simple answer. But for starters.........think about why it didn't start before. It was electrical wasn't it? Well, it's likely a similar problem if you have no spark. You just have to have a basic knowledge of the car's systems and go through the process of elimination. Just like the rest of us who have learned the hard way. A little research and some reading on the subject is a good way to start. I'm sure this is not the answer you were looking for but if you take the time to learn a bit about engines and the systems that allow then to operate, you will thank yourself later on for doing so. Give it a try anyway!!! Otherwise, if it's a matter of urgencey, take it to a mechanic familiar with Z cars. Good luck!

Each year we attend the MSA show, registered participants get a goodie bag full of stuff. This year we got a copy of a book titled TURN AROUND. It's all about how Nissan was save from sure death......a slow and painful death!!! Does anyone care to share their thoughts on this really good read book? All I can say is..................WOW! Wish we had someone like Carlos running the organization I work for!!! What do ya all think?

Keep looking................................. The guy must be dreaming @ $5kROFL

Have you looked up the price of what a new set of the same wheels cost?
