Here are some links to look at, showing the different bolt patterns and how the parts ift together, with labels. Seems like you should be able to swap companion flanges on a ZX to run CV's instead of u-joint shafts. I've never seen it described but it seems simple. People install 280ZX companion flanges (turbo or 2+2) in to 240Z hubs to run 280ZX CV shafts. Same concept. http://www.nicoclub.com/FSM/280z/1982/1982%20280zx%20FSM/ra.pdf http://forums.hybridz.org/topic/49194-differential-cv-lsd-hp-torque-r160-r180-r200-r230-diff-mount/

How far? Details. You might try raising the front or back of the car to make sure the bleed screw is at the highest point. The bubble can sit at the high spot while fluid goes out the bleeder. It's a simple system, but small details can get you. Like I said did you check the slave cylinder boot and you said that you "checked for leaks". Might not be thorough enough. You have to remove the boot to know if the cylinder is leaking, the fluid will stay inside. So a glance at it by eye won't do it. Might take some thought and study to understand. If you replaced the clutch parts because your shift lever was wiggly, there's much to learn.

Are these new parts? Rebuilt? Was anything else done? Have you checked the slave cylinder boot to see if there's a leak? Did the old parts work? Why'd you replace them? Lots of detail missing. Have someone watch the slave cylinder rod and clutch fork while you push the pedal, or vice-versa.

Sounds like a weak fuel pump. A fuel pressure measurement would tell. Leave the gauge attached and look at it when the problem happens.

The shaft axles will swap in to the R200, but the flange on the other end might not bolt up. Depends on your hub axle companion flange bolt pattern.

Are you posting for yourself? How many dead threads are you going to try to resuscitate? And where are you getting all of this advice? 3 weeks ago you were asking how much power an L28 might make. Regurgitating and recycling internet knowledge as your own is not cool. The two posts above look like pure fabrication. You should stop doing that. http://forums.hybridz.org/topic/122898-all-streetability-aside-28l/

I'm not a suspension expert but I think that a well-designed wheel/car/suspension system never rubs. The wheel stops moving before rubbing occurs. So one solution for you might just be more or longer bump stops. This will stop the rubbing, and you can keep the look, but the ride will still suck because you don't have enough travel. That's one of your problems, besides spring and shock rates. Your parts don't work together.

Are they shown in the schematic but you don't know what they do? Or are they on the switch but not shown n the schematic? Are they #6 and #7, or one of the five. If you have a meter you could at least chem them for either ground or power.

Where do they rub? Which springs have you looked at so far? Make a list, so you can avoid the "already saw those" cycle. "Coilovers" only offer adjustable ride height, if they're the design that just moves the spring perch up or down. Otherwise, they use the spring the same as a fixed perch.

Speed Secrets (capitalized). PipeMax version 4.0. Magical dimples. All of the below is true? Dryer exhaust ports? Because the fuel is burned so efficiently? Can't believe it. " 15-25-plus horsepower increases, a wider power curve, sometimes 100 to 300 higher RPM point of peak horsepower, less fuel consumed on the Dyno ( lower BSFCs ) and dryer exhaust ports. On the flow bench, basically no flow gains I can measure from roughing up the entire heads/manifold surfaces." There's a psychological factor involved when people do these "experiments" and odds are that other things were changed that affected horsepower in those hot rod magazine tests. "Oh yeah, I advanced timing 10 degrees, but it shouldn't matter" kind of stuff. Subconscious. That's giving the guy the benefit of the doubt. It might just be pure BS, to sell Speed Secrets. Just saw that Naptown Dave already commented re the golf ball. I didn't see the actual "theory" either, that better atomization caused all of the described benefits. The best explanation for something that can't be explained is in terms of something that can't be measured.

I thought golf ball dimples were for consistent air flow over the surface of the ball, so that they fly true. Not for more distance, from lower drag. If dimples helped flow, airplane wings and fuselages would definitely be dimpled. Sounds like voodoo.

Open up the mini-junction, look at the distributor wire ends, and all will be clear.

I pulled all of the "red flag" statements from your post. That engine combination is an odd one, not what an experienced "Z" person would put together unless they had planned for a turbo. (EDIT - actually, with the flat tops, that's a typical ZX engine. 8.8 CR. My mistake.) Makes you wonder. The "new" head (not rebuilt) makes me think it came from California Datsun (formerly Datsun Parts LLC), one of the only suppliers around, but one who hasn't mastered the art of the Z. I wouldn't drive one of his engines or heads across the country without making sure everything was in spec. "New" just means clean and worked on. SUs can be finicky and many people spend a lot of time getting them dialed in. Considering the odd assembly of parts you have it would be surprising if they were ready to go. The air temperature sensor is in the AFM already (on most AFM's). But most people don't run an AFM with Megasquirt. The cold start valve is described in the FSM. This kind of shows where you're EFI knowledge is at this point. Most people have a hard time learning EFI, so learning EFI from scratch, and Megasquirt, and getting it all sourced, and installed, and tuned, in one month is really a ludicrous proposition. Michael Wales says that his EFI swap can be done in a couple of days but it took him a month and a half just to source all of the parts. His buddies probably knew something about 240Z's or cars in general also. Forget about 12 hours. Finally, it's a 1971 240Z. The rest of the car is probably worn out too. Best to focus on bearings, and bushings, and transmission, and all of the other parts that get hot and fail on long road trips. If you do get lucky and make a choice and source all of the parts you need in just a few days then you could revisit the idea. But you'll probably get stuck on just finding a 280Z intake manifold. Don't disassemble anything on the engine until you have all of the other parts you need. Odds are though that you're going to find a problem on your new car that throws a wrench in to all of your plans. The EFI swap will be irrelevant. Welcome.

Miles has a 240Z which has weaker hub axles than a 280Z. Here's some threads re your question. Search the names to get more information. Rebekahsz is another who was drag racing, but on the stock axles. http://forums.hybridz.org/topic/109324-ford-88-irs-conversion/ http://forums.hybridz.org/topic/121328-snapping-stub-axles-now-what/?hl=sunnyz&do=findComment&comment=1135160 And here's a guy supplying the market - http://forums.hybridz.org/topic/121613-s30-ultimate-88-irs-swap-kit/

Everything is shown n the two links below. You might need something bigger than the phone you're pecking at, to read through them. http://www.nicoclub.com/FSM/280z/1980/RA%20Rear%20axle%20and%20Suspension.pdf http://www.nicoclub.com/FSM/280z/1980/PD%20Propeller%20Shaft%20and%20Differential.pdf

It still has the wrecking yard mark on it. Added two pictures just to confuse things, hard to tell what's right but it does show options. One from a parts web site and one from the FSM. Might as well flip it over and see.

The stock springs are preloaded. That's one of those areas of suspension that isn't often discussed. Ideally, ride height, preload, and spring rate all converge. More preload gives a stiffer ride over the small bumps, I believe. Something to remember if ride has problems. Not a suspension expert. I thought Prime might be involved. Oh well. Looks promising, your pictures came up full-size, pretty quickly.

It will run on the lower CR, it's been onde. Just thought you should know. You saw my post on other possible effects though, right? If the head's corroded, other parts might be also. Corrosion is usually from running water without antifreeze.

Nietzsche's unquoted works....

P90 and N47 have different size combustion chambers. N47 gives a higher CR than P90. In case you were looking for a direct swap. P90 on dished pistons is the turbo CR. P90 on flat tops is stock. N47 on flat-tops is "performance".

Photobucket links take you off the forum to another web site. If you Attach the files, they get saved on the Hybridz server and become part of the post., I think. Attached a couple to see..

Second the 280Z insulators. A common "fix" to raise the car, or vice versa with 240Z insulators. What is this Amazon Cloud Drive thing that you posted your pictures from from? I clicked it even though it was going to try to sell me something. Looks like a Photobucket type thing? But much faster than Photobucket. Does it cost something?

It's been described here and there. Some guys use a press, some use an air hammer, I believe. And a big oven, sometimes. Seems like an easy job to do in principle, and an easy job to screw up in practice.

Wow, that's pretty cool. You could try borini63, 88dangerdan, or zentech by message. They all sell parts. I think that borini63 might be in your neighborhood. That's a lot of corrosion though. Makes you wonder about the block also, like the core plugs. They're thin.
