This came in a 240z I got a few years ago, I parted the car out as a friend of a friend wanted something for an lsx swap and my uncle has been trying to sell me his 240z for ages. The z I bought from my uncle has a rebuilt numbers matching original motor so I’m not changing it. This L28 came from a 280z and is supposedly built. Unsure what it has, could be just a cam, I wasn’t the one who put it together. N42 block, N47 head. Turns by hand. Remanufactured starter. Intake and exhaust manifolds were on until I just removed them, it wasn’t sitting exposed. L28’s originally came in 280z’s but they can be used in 240z’s with carbs, an electric fuel pump, and ignition control (I have a Crane kit and a GM unit people often use available). $675 6-1 header available separately $195. Round top SU carb complete setup available extra with motor. Located in Buffalo, NY, I’d drive across the border in exchange for a bottle of vodka from the duty free heh Text or call 716-7two5-5366
I have a 240z with rebuilt E88 head, rebuilt dome top su carbs and I just went from stock manifold with 2.5” exhaust pipe and cherry bomb muffler to a header. I kept the pipe and muffler as the weren’t stock anyway, I just added a flexible connection from the collector to the existing exhaust pipe. Actually now I wish I didn’t do this modification. It’s really noisy and I’m not sure that moving away from the OEM cast iron exhaust manifold was a good idea. It seemed to do the job... any comment on the performance improvements or lack there of? One other point - within 6 months I had a fuel leak right over the header pipes even with all new fuel lines. It totally cooked the new fuel lines from the float bowls to the jets. They were cracking and perished. Dangerous. I have since replaced the SU carb fuel lines with correct parts, and modified the heat shield with an additional aluminum plate which sits under the fuel hoses/jets. I also added some heat wrapping to the fuel lines. Makes tuning more of a chore, but gives me peace of mind. Anyone have a solution to the header noise issue? Add a resonator? Change the muffler to a better one? I can tig/mig weld so would buy parts online and do the install myself. I’m not a boy racer (nearly 60) and it sounds like an F1 car now when I put my foot down. Yeah, I know- some of you would think that was a ‘bonus’. Richard
Hey all, looking for a used/new/spare aftermarket header (or perhaps full system?) for my L24. Not concerned with brand, just not rusted or broken. My stock exhaust is shot and it would make life easier to go aftermarket. Shipping to NC 28411 and I would like to use paypal. Pics and price to email@example.com Thank you!
So about 6 months ago I was out of town and got a call from a friend telling me that I was getting fine notices for not registering my 240z which I had been working on (It is an early 1973 240z currently completely stock). I told my friend to take it down to the muffler shop and have them throw on an exhaust just to get it passing inspection; well my friend knew nothing about cars and It showed when he was talking to the muffler shop because they overcharged him/me and put on one of the cheapest most restrictive exhausts you could imagine (1 3/4 in pipe, cheap restrictive muffler, non mandrel bent pipe, and they slapped it on to the rusty manifold). I have been driving it since because I need it as a daily driver but now is the time to change it because I can tell that my engine hates it. This is were my dilemma sets in. I want to put an l28 into my car because the l24 is starting to give out on me and I am tired of putting in lead substitute everytime I refill costing and extra 10 dollars. I also want my 240z to be running until I have rebuilt the l28 and it is time to drop it in, but with the exhaust It is becoming more difficult to drive. I would like to put a header on the l24 and new 2 1/4 pipe all the way through the car. However I am building on a budget and would like to reuse the exhaust once I drop the l28 in. I have heard that the E88 (my current head) and the P90 (my soon to be l28 head with flat-top pistons) have the same square exhaust ports. Will a header built to fit an E88 fit on to a P90 head, and will the rest of the l24 exhaust fit under the car after the engine swap? Thank you, I hope this all made sense
