"Eat your Po-TAT-toes!" (Alien Reference) Come to think of it, there are some CG circles I recall on some photos I saw someplace...you could probably scale them from a known objects size in the photo... Damifino where I saw 'em though!

Yep, the hex is Japan-Produced Billet. Just found one with 16.2mm lift (0.640") Pretty radical grind...I think I'll pass. Seeing if they can get me something in the 74-75 "Degree" rating for Japan. I'll keep my Japan Ported Head 'all Japan' I guess. If the guy can get what I want before I leave. It's hard to convey 'unground' to them. Or to my translator! I just need to find the source of the billet. If I can find that, me and Ron Iskendarian will have to talk...

Not really, time and performance marches on. The 'good old days'... really weren't. But let me ask you one thing: Does driving the Camry result in any sort of tactile feedback or sensory stimulation whatsoever? I have driven really quick newer Corvettes. They are a hoot. But they are also sanitary. I get a similar feeling in some of the 350's I've been carted around in or drove. They're a realy hoot to drive, and relatively quick easily. But leave me wanting something they don't give. As a second car, I'll take a 13 second 240Z over many of the current generation 13 second cars... Now, if I had to use it as an appliance, to get to and from work in stop and go traffic with A/C and a good Stereo... I might take that Challenger Hemi or Z whatever Vette... Frankly for that I'd be happy with a Mini Cooper S. Meh, it's like buying a refrigerator any more. It's all the same mishmash of crap out there, the market is pretty boring. For smiles per gallon...I probably have to agree the older cars got the new stuff beat. You can always get a smile driving something to the edge, anything---but the older cars provide that at a lower speed in most cases. Probably safer, though not if you shunt and twist it hard! Then you probably fare better in the refrigerator you bought off the new-car lot this year. But a Camry? Shoot me and stick me in the dumpster, I don't want to live!

There is a cure for that affliction, to paraphrase Sam Kinnison: "Move where the water isn't...OH OOOOOOOOOOOOOH!" You guys all realize that 'flood cars' are something not to be sold anyway, right? Over the Axle flooding requires a full service of the vehciles' underside. We are fretting over something that really, in the grand scope of things, not all that common, despite anecdotes to the contrary. If your car is in a flood that comes to the bottom of your seat, you got FAR worse things on it to worry about than the ECU! If it leaks from the outside it...FIX IT! It's not supposed to do that! OH OOOOOOOOOOOOOOOOOOOOOOH!

Oh, don't EVEN get started on Injector Placement. If it's an N/A engine, you want them on a stalk pointing into your velocity stacks at an oblique angle (5 degrees comes to mind), though each engine configuration should be optimized through dyno testing as to the exact best angle. For the close proximity of the spacer to an SU throttle plate it was best to have it hit the plate for cracked-throttle idle quality. It will impinge on the center of the plate, and as the throttle angle increases and air velocity increases (to a point) it will really pick up the fuel into the airstream homogenously, and keep from having any possible over-rich condition---better fuel distribution to all three cylinders on the branch. If the throttle opened any way but horizontal, I'm afraid the mix of a TBI setup would be biased to one of the cylinders during partial throttle. For port injection, of course it wouldn't matter... For max power with the injectors on stalks it might... Who knows? Build it and find out! And yes, VG30 synchronised Air Doors with linkages shortened will be a snap to get it all going, using a simple cable throttle. You build it, it's been about 20+ years since I had that though the first time (at the Okinawa Naha Prince Distributor, looking at the VG30DE in the then-new Z32.) It's terrible when you look at an absolutely new car, and the first thing you notice is stuff you could adapt to your own car. You don't see the new car and all the engineering, you see all the shiny new parts!!! When we took tape measures to the preproduction Titan at a Car Show in So Cal the Nissan Handlers ran over and quickly wanted to know who we worked for and what we were doing. He just sat agape when we told him we needed to measure the height and width of the engine to see if it would fit into an S30... As he walked back, he said incredulously 'These guys are insane, they were trying to see if this engine fit in one of those! They're insane!' (While pointing to John William's Turquoise and White 240Z)

Not according to the guys at the Nipa Hut in Angeles City, 1987. There were PLENTY and MANY VD Cranks available there. I hear there are an abundance in Bangkok and Kuala Lumpur to this day. Zeero may be able to tell us, from anecdotes, of course. Though, if you're a stroker, a VD Crank is not something you will necessarily acquire.

You obviously have not experienced sonic boom on low flyers... by the time you look up, they aren't even a point on the horizon! Then again, overseas, there is not the restrictions there is here in the States regarding stuff like that. Having seen F15C's in low altitude demonstration of the above principle, I'd figure you saw something subsonic. Horizon to Horizon on the open sea, out of landfall in 20 seconds is sloooooooooooow! Wrap your mind around that! The kind of speed from recognition, to sonic boom, to speck on the opposite horizon is not even time to say 'here they come, cover your ears, there they go!' Guys in the Navy will know what kind of speed I'm talking about, they have seen it. It's actually kind of frightening when you consider your own situation...can't see em coming, can't hear them, and by the time you do, they already dropped ordinance and are a speck on the horizon. You wouldn't know what hit you! I digress...

Here is another thing off my drawing board: Spacers behind your SU's with counterflow injectors firing at the backside of the throttle plate. I forget the thickness, but recall something like the same amount of the 'doublethick' thick spacers the AutoX guys run to boost torque on the SU's. You could use a gutted SU, or simply any air door. There is enough space to run DUAL injectors in there if you wanted, meaning twin Ford 370's (and no big injector idle control issues) on each adapter. Frankly, with a short air door you could make a real thick spacer for even more torque bump. I actually drew out the spacer on my drawing board at home... It works, and there is plenty of depth to make bosch-style injectors fit in there. With a 'thin' sandwich style butterfly, you could even keep the adapter at a minimum thickness required to fit the injectors at the requisite angle for proper impingement on the throttle valve, and leave lots of room for impressive spun aluminum polished air trumpets, two each, fully radiused and 3"+ in diameter with domed filters in the end... Oh, and yeah, 680's will be more than enough. My bud's cammed Rebello motor is overwhelmed with the 720's. Just too damn big, but he refused to listen to me about trying cheap and available 550's first while in development... lead a horse to water, then shoot it! Not that I ever gave that setup any thought before this very second, mind you...

My wife says my Triple 44's are 'like an on-off-switch' though the same triples were on her Fairlady for years. When you add a turbo that enhances down low breathing appreciably, the off-idle modulation is an issue. I'm not saying I don't have a problem with it, but to say that the modulation is just not an issue is not really truthful. It's touchy, touchy as hell with 44's and a blower. Those same 44s without the blower weren't nearly as responsive at tip-in. And that was AFTER the conversion to throttle cable actuation which made tip-in much more managable! It's like a Mustang with a 3.8V6 and one with the V8. Tip in on the 3.8 is atrocious, hard to start it wihout jumping (with a slushbox). The V8 is more managable as it has a smaller body. But after the first car length the V8 pulls the jump you got with the same throttle opening of the V6, without the initial jump you owuld think the V6 was a powerhouse compared to the V8. Tip in enhances perceived power, but doesn't do much otherwise. You can see the effects of sizing looking at Ford products like the Explorer. HUGE throttle body on the same size engine as smaller vehicles. But gearing and mass of the body will mask the tip-in. What it does give you is the feeling the truck is 'jumping' from a start---like it really has power. Due to the mass, it's dampened. Put that same throttle body on a Mustang, and you find it really hard to take off without at least chirping the tires, if not outright noticably squealing... No weight and high gears to take away that airflow rush bump in torque output. Those e-bay manifolds are similar tothe Trust Greddy marketed unit. My bud cut the front of his to reposition the TB better, and used (as I recall) a Q45 TB on it. No clearancing necessary. The weld shop made it invisible. Looked stock (or at least 'Greddy Stock'!)

Heck, that's where the one is in my 260ZT right now, it seemed the easiest place to put it. Likely it will go somplace else eventually. If you don't have a radio it's spacious enough for most... But if you want to use a heater, there are probably better areas to put it...

Ahhhh! A fellow hoarder in the making!

no no no no no no no! Send it in to Overnight AM Coast-to-Coast. Post it on their website. Mention that it's near HANFORD. Oh man, the comments there would be interesting to read! Delete the logical explanation here quickly before it's recorded on one of those webcrawlers, and let them explain the gubbmint conspiracy involved in it's concealment. Obviously the problems in your yard happened when the flying gubbmint black UFO you unwittingly photographed flew over your house and your things were flattened by it's impulse drive engines! (Yeah, you got it, I arrive late in the evening to LAX and listen to AM radio on the way home... My Late Aunt Renee loved George, and she was so excited to learn I knew who he was.)

Oil/Water as primary, which will bring it down to X temperature, and then your original Air/Oil unit mounted as a supplemental to trim another couple of degrees off of it...all controlled with an Oilstat to keep the oil temperature constant. You can always cover excess cooler, but if you don't have enough, yer screwed!

I don't know what the 'velocity over flow' or 'fluid dynamics at WOT' is in the way of a justification. The Electramotive TB was pretty small, definately not 90mm. And they were making what? Lets say 780HP... Arguably they spent WAY more time at WOT than the average street driven Z-Car so I'm thinking I should defer to those guys' engineering analysis on 'velocity over flow' or 'fluid dynamics at WOT'... I'm not saying I have an answer, and I'm not denigrating a 90mm TB. I just ask the question if Electramotive and their engineering brain trust (which is easily more brain power than is in my head) decided on that specific size, I have to wonder other than cosmetics would the larger TB have? Cosmetics is fine, but the real measure is functionality. If it works, then it works. But if you can get by with something smaller and it doesn't affect functionality, smaller isn't inferior. As for the large/small/large comment, an orifice is a good thing to have monitoring flow from non-linear compressor when feeding a receiver or suction bottle of a reciprocating compressor. This has to do with the sensitivity of the centrifugal machine to surge during loading and unloading. At WOT, having the restriction (the TB) makes for a convienient place to use as a guide where to position the unloading (blowoff) valve. It makes the compressor section unload (drop pressure) slightly differently than that part of the compressed air system behind the TB (the plenum). It lets the engine suck down what is in the plenum, and unloads the compressor side of the equation slightly more efficiently. Without that small restriction, the dynamics of the unload through the blowoff is different...

That's why they make stand-offs! Mine goes on an aluminum 'hat' that sits the ECU above the carpet 1/2" or so, and then has a 'cover' to prevent the horsehair from falling on it (or whatever Datsun Cushions are made of...) The idea came to me not so much from guys putting monster amps under there, but the fact that in the 10-Series Cars (Like the Maxima, and several JDM Cars) that is where Nissan put the ECU! Under the passenger seat, matter of fact. Makes a nice donor harness for a Z, BTW... I might also note that leaking seals may be a reason to get them fixed so they don't leak...

680CC or 1680cc? I know someone who used 1000cc injectors in his TBI setup and they weren't idling as best as they could. Eventually went down to 720's and got a decent idle. I forecast 2 X 550CC's, as if they supported a 215HP Ford V8, I figure they could support my measly little Datsun. That works out to what? 110PPH, at 1/2 # per HP per Hr for an N/A, that's right around 220 hp, and with an 80% limit that's still 160-170HP. Though those Ford Injectors may be rated on the 'low' side. For a realatively sedate L6, a pair of 550's should be fine. For a Stock Conversion damn tootin enough. I doubt many would ever need 720, but my bud was ultra conservative and paid the price in idle quality. I don't know if the TBI is governed by the same 80% duty cycle as port injection...

At $3 for every 30 seconds on the phone, I think right now, that is not an option... NTT is not cheap to call mobile to landline. And I'll be jiggered if any of them are there over the Thanksgiving weeked. I'm just going to take it as stated, they have 'lugs' like the stock Datsun stuff, and the 'hex' is an independent billet produced in Japan. The inquiring will now start. Okamura will be busy on the phone asking 'technical questions'---I can see it!

retarding the timing is a way to slow down the engine. Lock the advance weights in a distributor and see how sprightly the car accelerates... Advance is best dealt with on a dyno, add till you stop gaining power, then back it off a comfortable safety margin. Less is wiser than more. Generally you don't want any more than you absolutely need.

So "A" Early cam likely Nissan Early Production (NLA) so that begs the question, what does the CWC Cam Look Like (Which was the point of the post.) Doubt it's hexagonaly oriented, and it doesn't have 'Japan' on it... But a confirmation they have lugs (or don't) is the purpose of the post. Bueller?

It does, but the effect on spark scatter is really not that important on most applications. When you drop throttle there is 'slop' in the gear of a fraction of a degree. You can measure it with an indicator. But on the rotor position it's irrelevant, for a trigger wheel driving a COP setup it might affect it, but... In theory absolutely, it is a factor. But in practical matters it's not an issue. You're not planning on going to 9500+ are you? (We did run the Tec2 with that drive to higher rpms---over 9500---and that setup worked as well. But we ended up having issues with the O2 feedback circuit, and changed the system. But it wasn't making an appreciable difference on our setup. Maybe it would on a Turbo Car at 30 psi + boost running to 9500+ rpms it might. But that is not my instance, so though even in theory there is a 'problem', it was not a practical consideration.) And you're right about the popping out of gear: syncho or heavy gearshift...

rods are forged from the get-go on the nissan L

For LHD cars: Under the Seat Behind the seat on the compartment bulkhead wall (or in the compartment) Same place as a 280Z, using it's brackets and kick panel cover, modified (PITA, under the seat is easier and like mentioned your foot is always all over it) For RHD Cars: BEHIND THE GLOVE BOX...IT'S CAVERNOUS! Because it fits so well up inside there, I have not thought to mount it anywhere else on those cars. Later cars have AC a lot of the time, and it interferes with mounting them there, but on a RHD car, the stock mounting place for an ECU does not interfere with the driver's dead pedal! Depending on the ECU, 'in the engine bay' is also an option.

Oh man, I hope Frank280ZX doesn't see those widebody kits with the door bulges... I only got so much space on the plane! Checking through Yahoo Auctions myself, since I'm there now (Japan)... Getting the guys at work to translate annoys them, except the guy with the MX5, who now takes great pains to make sure 'I'm attended to properly'---which means spending time translating auctions for me instead of doing what he's paid to do (engineer) LOL Domo Arigato, Okamura-san!

/Treads Conspiriatorialy/ What, no prices listed... Muahahahaha! /Slinks Off/

Yeah, a ROAD TRIP over Memorial Day doesn't arouse suspicions. And a baseball bat ductape, tyvek suit, and a plastic drop cloth could be easily explained any number of ways during a traffic stop, especially if they look to be randomly arrayed around the back of your hatchback... Now, if you also happen to have a collapsible entrenching tool, a bag of quicklime and a battery operated sawzall in there, you might not explain it too easily. "I'm visiting a friend to play softball and do some gardening later in the evening" just doesn't have the ring of truth to it, even to Bufurd T. Justice (or Barney Fife, for that matter!) Some things are better paid for cash just before you need them.
