I have a L26 serial # 043448 that will probably be for sale. The block has been cleaned and painted. I'm going to replace the freeze plugs before the sale and I'm willing to get the cylinders bored and honed if the buyer wants and the price is right. I am open to offers to .... PM me.... took e-mail out for privacy reasons... with the subject "260Z Block Offer" please, or post on here. Let me know! Buyer will need to pick up or arrange shipping from 32536 zip code in FL.

I am looking for a header flange for a square port (or round port if you have one) head. I am going to make a custom header and want a flange to work from. If you have an old rusted out header you can cut the flange off, I will have a new one made from it as a template. Let me know if you can help... Thanks Jason

What hose connections must be connected on the stock '71 air cleaner for a 240Z to run correctly? For example the connection below the air cleaner intake.....I see some cars with nothing attached to it. http://www.classiczcars.com/photopost/showphoto.php?photo=15480 I am thinking of buying a Z Theraphy redone air cleaner and was curious which connections not currently connected that may have to be added. See my current setup below. I am hoping I can just swap out the air cleaner K & N element and bolt on the refurbished air cleaner.

I am in the process of restoring a 260Z Air Cleaner and want to know where I can find the decals that are on it. The ones that are on it are decent but I want them to look new. Also I need the gaskets they were all worn and in need of repair. If anyone is interested in this let me know. I'm going to sell it when I'm done. It is the one with the summer/winter switch on the mouth opening. Thanks alot guys! Mike

Anyone know of a good way to store bare metal parts that may have to sit around for awhile? I'm thinking something the size of an engine block. The outside will be painted but the guts will be exposed and oil free while I wait to have the bottom end balanced and the cam ground etc. Texas is extremely humid so rusting may be an issue. I say that but my partially bare metal shell has been sitting for over a year with no obvious problems but I think you have to be more careful with parts that won't be painted like the inside of an engine. Thanks - Michael

<img src="http://memimage.cardomain.net/member_images/9/web/669000-669999/669670_88_full.jpg"></img> is that right? they are gapped at .05 cause of the ZX upgrade and MSD coil....should i gap them at .04-.045? im concerned about the black ring around the outside. all new sensors, new AFM, new injectors, new everything, and 5000miles on the rebuilt engine... i cant seem to figure this darned tuning thing out. UGH!

I happen to notice a spot on the floor where my Z parks. I jacked up the front and checked her out and it looks like it's seeping out of the reverse lamp switch right next to the fill plug. Has anyone here had this problem??? Does the switch have to be replaced with a new one or is it possible to put some kind of sealant on the threads and reinstall it??? Thanks in advance for your help.

I just go my Ztherapy SU's in the mail yesterday and put them in today. It only took about 1.5 hours to get them in and tuned. I watched the video last night which was a big help. I took the car out and it feels like a hole new motor. The motor now pulls to 6500K+ or so where as before it started to loose power at 5500 or so. The power through out the power band has increased noticably. The old SU's must have been in bad shape. I hit 2nd and the car spun the tires and launched forward like never befor, usually the tires barely spin, just a chirp. It feels like I gained 25HP, that could be more than reality but it feels great. The idel is much smoother and it sits right ar…

I'm getting ready to swap enignes in my 73. I'm trying to plan so I can do it over a weekend. I will pull the engine and trans, then swap the trans to new motor, replacing clutch and throughout bearing in the process. Then it goes back in. the car is in good shape but has not been apart since new. I hear its a good idea to replace bolts (i am replacing motor and trans mounts). My question, and I have tried to find it in searches, What bolts will I run into and how can i find the dimensions in advance so I can order them? I live in the boonies, so I can't walk down the street and get them. Thanks guys

I just finished putting a 5 speed transimission and 4.11 R180 into my 73 240. So far I really like the new ratios, but above 70-75 mph or so I start to feel a vibration that doesn't feel like a tire, but gets stronger as I go faster. It feels like it's vibrating the whole rear end of the car and it wasn't there before the transplant. So here's where I need help from the group. I figure it's either the tranny or diffy that has a balance issue (since that's what I changed), OR maybe it is the driveshaft which is now turning faster. Here's my reasoning: I have things right in my head, given my old diffy was a 3.36, for the same speed my driveshaft should now be turnin…
