Hey guys, Is there any data out there (like dyno numbers) how well the stock SU air filter box is working compared to 2 round K&N filters? I installed a K&N filter mat (for the stock air box) and did not buy round filters so far. Top end engine performance is not great, it feels like from 5000 rpm on no further power is gained. A/F ratio is spot on, though (wideband installed). Of course this could also be due to the relatively small SUs on a 3.1L stroker.. I just love the simplicity of SUs. And much more budget friendly of course :) BR

Hey folks - Last time I did a plug change, I used autolite plugs, and the car ran fine, but since it's been sitting, I'm going to go ahead and change the plugs for NGK. Now, I've seen a lot of people saying that BPR6ES is the correct plug, but NGK says that it's actually BPR5ES-11. I've also seen people say don't use the BPR model, just the BP instead. So naturally I'm confused, and searching gets me a lot of results from people with 240s, and I'm not sure if the FI on the L28 makes a difference. What do you use in your 280Z?

Anyone have a somewhat reliable count on approximately how many 240Zs are still left? I wonder if Carl Beck has some insight into this? There were approximately 172,000 sold........It would be curious to know how many restorable cars are left....eh? So many have been crushed....how rare are they? Guy

I've dinked around with several engines in the garage and have always wished I didn't have to mount a transmission to spin the motor. I thought of a possibility and had some scrap steel and time so worked up a quick mount, that actually works. I had started out using a spare starter and the back of an engine for measurements then realized that the backing plate on the engine has all of the necessary holes, a ready-made template. If you have a drill press, and a jig saw, it's not too difficult. A battery, starter, and the plate and I can spin a free-standing engine as long has it has a flywheel. The steel is 3/16" x 2 1/2" mild steel, hot-rolled I beli…

I have a friend here with a 72 Z with auto trans, that needs a new flexplate. The ring gear teeth are all chewed up. Rockauto has one listed for all the 280 and 280zx, starting with 75 but nothing prior to 75., Here is a link to the only they list for 75-83. https://www.rockauto.com/en/catalog/nissan,1983,280zx,2.8l+l6,1209394,transmission-automatic,flexplate,8608 What are the chances of it fitting the torque converter on the 72? I suppose you could get a matching torque converter and flexplate (they list both in the 82 stuff) if there something unique with the early converter. I know there are hundreds of you out there intimately aquainted wi…

Well I'm in the process of removing my 3.1 classic stroker engine for sale, and decided to do a bit of measuring and testing before it leaves so the new owner has an idea of what to expect and what service it might need. It has been in service for quite sometime. I wanted to do a leak down test, and the best way to do that is to remove the rocker arms and keep all the valves shut. That way as you apply compressed air to each cylinder, if and when the piston gets pushed to the bottom, it doesn't move the cam and open any valves. This way you don't have to get and maintain perfect TDC while you do each test. So I merrily proceed to remove my rockers. As I begin re…

Hey guys, I finally got my '76 280z back on the ground after replacing the clutch, flywheel, and a few other components while I was there. The Clutch is a Centerforce Stage II and a lightened Fidanza flywheel. The very first time I ran it, it went right into reverse and I back it out of the garage. I then realized that I really needs to bleed my brakes, as they were almost none existant. I shut the car off and pushed it back into the garage and called it a night. I bled the brakes the next day, I then started it it'll no longer go into gear, which was the original issue. Goes into gear fine with the car off. Slave cylinder moves a considerable distance when th…

I was going to check/adjust my valves for the first time but I was wondering, a previous owner installed a racing cam. Does that mean that I need to use a different setting for the intake and exhaust valves? 280 engine with lots of PO modifications installed in the 1980's Round-top SU's Mallory electronic ignition
