Been reading the "How to modify Your Nissan Datsun OHC Engine" By Frank Honsowetz. Reading about valves and their head shape. It says you can get stock valves that have been modified (Numerically Controlled) in the way they are machined. It gives a part number 99996-N1100. I am wondering if anyone knows if these still exist and if so is it worth trying to get a set and paying $$$ or just getting a reputable machinist to cut stock ones the same way? Good book BTW. Gav

A fairly simple question that isn't explained in the Haynes book, et al. I thought that it's supposed to disengage when the air coming through the radiator is 'cool?' Gives more HP while you are at speed, then engages when not rolling along? My fan turns all the time, even right after you start the cold engine. thx

Ok, finally started to mess with the 280..... So far I have changed the oil, oil filter, fuel filter, noticed a nice improvement all around with the oil change. Defiantely over due. Real bad blow by. Smelt more gas than oil..... Not a good sign. Today I got in my rebuilt air flow meter. Swapped out the old one. Car fired right up. Let it idle for a bit so the computer could adjust. Took her out on the road, first gear responsiveness much improved since the old air flow was gagging at low RPMs....but here's the problem.... Car basically refuses to go faster than 60mph, or over 3000-3500 rpms. I also notice a "puff" of blueish smoke in between shifts. Power…

I hear this cliking sound comming from the motor which I'm sure is because my valves are loosen up, which needs to be adjusted (tighten up) does anyone knows how to do this? is this something I can do on my own of should you suggest I take it to a Z shop and do this? and how much would this cost? thanks

I just bought a 73 240z with the original engine, with maybe 140k miles on it. The problem is that when I'm gasing it, the engine chokes like it can't breathe. Since the tach does not work I don't know if I'm just redlining it or what, although it doesn't seem like I'm even close to the redline.

Last Fall I posted about my 75-L28, N42/N42 burning oil on decel, and due to your great advice, I totally rebuilt it this winter, myself...first time. And its running great.. However, Sat, I took it out for "spirited" driving with the Z car club, touring So. Vermont rural roads... at lets just say... at challenging speeds !! Well its still creating some odor/smoke on heavy decel mode. like long down hills, and going thru the esses.... Its got new rings, head rebuilt by shop with new valves,seals, guides were OK . Compression readings after 500 miles breakin are 160(2) 164(2) and 168 (2) . Manifold vac is 21 at idle. No oil usage to speak of, maybe 1mm o…

I'm planning on replacing the engine in my 73. When I got the car it had the 2.4 and 4 speed. It then got a used 2.8 with Automatic Transmission (long story don't ask The used 2.8 is very tired and leaking oil. Its time to switch it back to a manual transmission also. The 2.8 has round exhaust ports and my stock manifold is still on the car which is square (I'm sure that doesn't do much for performance) I can get a 2.8 rebuild with square ports. Although comparing a 2.4 with a 4 speed to a 2.8 with A/T isn't a real good comparison I do miss the high revving 2.4 engine. It used to pull pretty strong right up to the redline. I'm not sure if it had any mods pr…

Is there somebody thar makes a "tune up kit" for the 280Z? I mean stuff like dizzy cap, rotor, points/condenser, plug wires, etc. What else should I get? All I did so far was put in new spark plugs. thx

Does anyone have a picture of a 280 ZX engine bay? I'm particularly interested in a shot that shows the appearance of throttle linkages as I'm considering buying some for a mod. to fix my sticky throttle. The engine they are coming off is an L28E and I'm wondering of the connector bushes on the throttle rod ends will snap onto my 240Z throttle linkages. Anyone?

Hey All, I never got much of a response from Hybrids, so this stays here where i feel happier:) Please note, in the near future i'll add this info to my website with pictures included. The Scenario *********** The warm L24 sounded great, but just didn't have to go when push came to shove. I'd always dreamed of the mighty Rb26 but it was far out of my price range. So i was off tuning my SU's one day and took the car for a sprint down an industrial street - to the amusement of a Police cameravan, i prefer to consider myself lucky i was only caught at 104 in a 60, not the 140 icould have been. So i lost my license, and though PERFECT. Since then every dollar has gone into m…
