I just disassembled the N47 intake manifold off of the head, and started to work on the rest. Then discovered about 4 days later about the specific details around emissions. It was a pain! The sale is currently pending, with a down payment. Now looking for a 240z!

The main problem is that I really want carburetors

Unfortunately in Colorado their is a hard stop on classics starting in 1975. To be considered a classic after 1975, the car has to have been registered as a classic prior to Sept. 1, 2009, and the registration has never lapsed or expired. The alternate is if the car is 32 years old or older, where it then has to pass emissions once but can't exceed 4,500 miles a year. In short, I have to fuel inject with EGR and pass emissions

I am still pretty excited about the Z, and if I had 10k more I would probably just go buy a 240z and keep both of these. Right now I am kind of 50/50 on the car and am going to keep restoring it until someone buys it or I fix it all the way. But with the emissions details I just learned, it won't be the "dream" car I thought of and so would rather sink my time into one that achieves that vision if I have the choice. Don't get me wrong, I will never not love the s30's! 🙂

View Advert 1978 Datsun 280z I bought this car a couple months ago, and 1 simple device broke leading to me wanting to look elsewhere. 66,000 original miles 4 speed factory AC The car was my daily until it began to overheat. Turns out the EGR broke, leaking exhaust right into the bay and causing the engine to heat fast. In fixing the EGR, the bold connecting to the exhaust manifold broke. To fix the EGR and Exhaust Manifold, you must take off the Intake Manifold. Knowing that, I decided I wanted to convert it to carbureted instead of fuel injection. I started working on that removing the intake manifold, radiator and alternator. I just learned that my vision for the car wont fly in Colorado with the new emissions regulations having a hard start in 1975. This kind of breaks my dream for this car, and considering i think it would be best with someone else. If you have a solution please let me know. If you have an offer, I welcome all. At the very least, I love to talk about these cars Advertiser SupremeCling Date 11/30/2021 Price $10,000 Category Cars for Sale Year 1978 Model 280z Vehicle Identification Number (VIN)  

I have decided that the right thing to do for my Z is rebuild it. I had planned to do so eventually, but much later down the line in my ownership. Here is why: Rust on Floor Pans needs replaced Rust on Lower Front Fenders and Dog Legs needs replaced This post resulted in this: Broke head off of bolt in exhaust manifold that connected EGR to exhaust manifold which means I need to remove the intake manifold to replace the exhaust manifold Discovered more surface rust that is on the cusp of becoming cancerous rust Needs repainted After discovering more rust when working on the EGR, I could no longer avoid what I knew was coming. I love these cars so much, that I would not feel right letting this one get in any worse condition. It is a real bummer too, because the engine and transmission have less than 70,000 original miles on it. I do have logistical problems though. Primarily being that I live in Lodo of Denver, Colorado and do not have a garage to work on the car. My brother offered to let me use his garage in his new house, but he bought the house a week ago. And I have never done a rebuild before, so I am learning as I go So...does anyone want to rebuild a 280z with me? I am sure I am going to need tons of help any way, but wanted to see if anyone wanted to work on a car for sport!

Yes, that is what I meant by kit. I posted the parts above as: Plate Plug (both long and short) Vacuum Caps

Turns out I have diamond ports! Any recommendations on aftermarket headers with diamond ports?

Is there a way to find out without taking the exhaust manifold off to check?

Do you have any recommendations on headers? I believe the L28 block has square shaped ports, but most headers seem to have circle shaped ports. Do you have any insight on that?

Follow Up: On the 18th of September, I began to work on EGR after receiving the EGR Delete Kit. The install of the plate was simple. Although, I believe I might have taken a bit too much off the manifold when using a Dremel to try and remove the caked on gasket. But that wont matter, because I will likely have to remove the Intake Manifold now... I soaked the nut/bolt that holds the EGR pipe to the Exhaust Manifold several times in several de-locking treatments. The head still broke off because the piece is likely rust welded into the manifold. So now I need to manage that issue. I am thinking of just going straight for headers and upgrading the exhaust system all together. Of course I am entertaining all thoughts and would love your feedback!

I really might go that direction. It would be hard to abandon my vision for the car. Maybe ill just come back to it in the future That is one of the greatest things about these S30s. You can continue to work on them and change them

Dayum Those Jenvey's look really nice. And way cheaper than Mikuni Any experience with them?
