The good guys will have to buy more guns now just to keep things even.

If you take the black cover off of the side of the AFM and look closely you'll see the tiny contact points for the pump switch. A metal rod closes then when the vane opens. You can bend the rod to adjust it if it's off. But if you have a hotwire with a switch, it's irrelevant at this point.

The next owner is going to be so confused...

The 10 seconds then die behavior is actually typical of the AFM fuel pump relay switch not making contact. It's bypassed during Start if you're using the fuel pump relay circuit as it was intended. You can short it or bend the control rod in the AFM to fix it.

I forgot that the 280ZX companion flange has the same 25 splines as the 240Z. That looks like the 280ZX flange swap, there are writeups out there on it. Still worth keeping.

The 240Z's rear hub companion flanges either have adapters or are modified to use those CV's. Don't throw them away.

Just guessing, but the CV shafts are probably worth more than the diff, if they have the right spline count for a Z R200. They're hard to find anymore. Measure the length and count the splines, somebody will probably take them. Call them 3x2 CV shafts. Here's some ratios if you want to get closer to what car the diff came from. Good luck. By the way, you can't post a For Sale ad until you donate a few dollars. It's a site rule to keep out the scammers. http://www.nissansilvia.com/forums/index.php?showtopic=337751

Not a bad idea. The 1978 280Z rail is also a direct swap, and one piece. 75-77 are the three piece rail that you have now. The ZX rails will swap but the cold start valve tube will need some bending. Nissan redesigned the intake manifold for the ZX's, although 1979-80 is a transition period for the L28 engine. Not sure what they did for intake there. They can all be made to work.

Maybe a 200SX or 240SX? The front mounts look similar, small holes in small ears. The CV style looks early 80'sish, 3x2 holes. http://www.the510realm.com/viewtopic.php?t=22269 Get the ratio and see if it's open or VLSD. I don't think that it would be CLSD. Probably an open diff installed for the ratio.

And odds are good that the crud in the tank and lines came from water in the fuel. If it got through the filter, the injectors could be rusted. They're sensitive. The injectors are easy to remove as an assembly still attached to the rail. Don't miss the bracket held on by an intake manifold bolt. That's the cause of many bent fuel rails.

Where are your fuel pressure measurements? Between the filter and the rail.

You should to be able to find one out on this side of the slag pile. If shipping is huge.

"L" means blue in Nissan diagram world. 76 still used a ballast resistor, with a start circuit and a run circuit. Your area of interest starts at lower left. http://www.atlanticz.ca/zclub/techtips/wiringdiagrams/76_280z_wiring.pdf

Follow the circuit. If Pin 1 doesn't have voltage it's either not connected to the coil negative terminal or the coil isn't getting power. Or the coil is bad. I believe the wire at the coil is blue.

Have you checked Pin 1 for voltage with the key On?

Why not put a tape to it first? If the rails are bent, a stock member won't fit anyway.

Read the last post in the Hybridz thread you sent him and you can understand why he backed off. You went to someone who considers himself somewhat of an expert in the field and dumped a large load of other expert opinions in front of him, EMPHATICALLY stated, that are the opposite of what he advertises on his Facebook page.. Who would want a piece of that?

I would take some measurements and see what you're dealing with. Maybe somebody repaired a damaged crossmember. I underlined two simple ones, one between the rails and one to the crossmember mount bolt heads.

Weird. Did somebody do some funky body work under? Is that even the stock 280Z crossmember? You might open up the Body chapter and take some measurements.

He's probably seen the discussions about Sensa Pari and is avoiding any Hybridz association. The OP probably could have had one made but he might have referred to the JeffP thread and ruined his chance. Ariel/ISL33P never came back with the flow numbers in that other thread. His business, and the Sensa Pari fiasco, shows that there's a demand out there. Ron Tyler and BRAAP's work showed that bolt-on performance for the L6 is not easy. Lots of L series engines over there, seems like somebody would have done one already.

Do you mean that the crossmember has been lengthened, where I marked it? Those welds?

I'm cynical in general, especially with the old internet making it so easy to create an image from nothing. The CPC Facebook page looks just like the Sensa Pari stuff. Cut an old manifold, install a neat-looking plenum. It is odd though that they wouldn't even talk about taking your money. Could be that they're just managing their customer base. You're not what they're looking for.

If your business model is based on creating an image then controlling that image is important. If they build your custom manifold and the wrong person gets hold of it later, they could spend their time explaining why the ports don't match. "Look at these CPC ports man, they don't even match!". Much easier to make a shiny manifold with good welds and matched ports. Everything "looks" right. It's not about performance, it's about appearance. I've seen the reversion discussions and they make sense in certain applications. These CPC guys might know also but just don't want to deal with it. Or they don't really know and are just sticking with what looks right. Sensa Pari was just a welder with an artistic flair that stumbled in to a pile of easy money. He couldn't even get his parts to bolt on correctly.

How are these guys different from that Sensa Pari guy? Jeff P has one of his manifolds, still waiting for his review.. There's no performance information or theory on the CPC Facebook page, just a bunch of comments about nice welding and how good they look. Do they have a real performance history or are they another show-performance company? Seriously, wondering...

But you understand Jeff P's?
