I put this in the "turbo" section cus I didn't see any other appropriate place, but it probably applies to the turbo somehow. I have a 1978 280z with an '82 L28ET engine. It is stock everything except for an added oil cooler. I currently have a SUPER DIRTY K&N air filter that sits in front of my radiator via some custom piping. I think the previous owner put this on in 2004 and hasn't changed it since, so I decided I would just get a new one rather than try to clean it (see below). I found the current filter online: https://www.knfilters.com/search/product.aspx?prod=RE-0910 However, I found a very similar but slightly larger filter below it: https://www.knfilters.com/search/product.aspx?prod=RE-0810 The second filter is about an inch longer and an inch wider at the base. However, it will definitely fit in the current space, so it would be very easy to swap to this size. Is it worth it to buy the slightly bigger size? Are there performance benefits/downsides, or will I not even notice this small of a difference?
My 280z has an AZ zcar 4 barrel Holley carb manifold on it and I have deleted the PCV, that would normally vent back into the stock EFI manifold, with just a filter venting to atmosphere. The engine runs great and pulls hard but I've noticed oil fumes while Im driving and engine braking, now I have no engine oil leaks and my engine doesn't burn oil, so i have isolated the smell to the air filter that Ive attached to the Crankcase vent tubing on the side of the engine(shown in pictures). My question is, can I run any inline PCV valve with a rubber hose running down toward the underside of the car with an air filter on the end? or does the PCV need vacuum? I know I'm losing some power by venting straight to atmosphere, I understand that vacuum in the crankcase can increase horsepower in some instances, but I mainly want to fix the oil smell. Thanks.
So I've only posted a couple times and I have lots of pictures of the things I did/do to my Z, and I do have a question. But first a little show and tell . I was frustrated I couldn't find air horns for my Weber carbs that I thought where correct (opinion only), so part owning a machine shop, i made these. I chose to make them two piece because they are easier to machine being thin wall and I only need to make the bell half if I want to change the design later. I have two questions .. 1) is there anyone that makes filter that are actually filters?. (As opposed to just mesh screens I've seen) 2) should I have made the bell half tapered like I did? I do apologize if these questions have been beaten to death and I did search so feel free to tell me to search more if that's the case.
