Those are all the pictures I have tonight, and now that you mention it it *did* seem like it might be a little flatter than the typical 16 valve sohc valve cover. the HF im driving now has a 16 valve sohc vtec motor with mpfi, but its like, decent sized, not this puny HF intake.. It started out as a stocker though, and then got swapped to TBI DX-ness, before it became what it is now. I should compare the two.. but tomorrow I will be pulling the valve cover just to find out.
what engine code should I be checking for on the block? I cant recall it now but I had my eyes on it earlier tonight, I wanna say d15B.. but my brother said it was basically the engine that was found in a VX civic?
god, i dont wanna join a honda forum..... the more hybridZ people I get in on this the better heh

I'm kinda stoked!
The automatic tranny in my POS subaru GL-10 crapped out on me about two months ago and I was without a car for a few weeks, and then threw a headgasket onto my brother's CRX.
His car is an 88 HF that has had a japanese 16 valve VTEC engine, intake and computer swapped in, along with an SI transmission. The interior fell apart, so he ripped it all out, and when he got his mustang that he drives now, the car became a second driver/autocrosser. He pulled EVERYTHING out except a racing seat and harness, the dashboard itself, the steering wheel/pedals, and the gauge pod, and put in a roll bar. No driver, half a tank, the car weighs 1830 pounds, and probly has about 110-120 horsepower. Suspension work, intelligent stuff but nothing major, and the car is FUN to drive.
So I've been looking for a car to buy for next to nothing (I seem to be perpetually broke) and not having much luck, but I've had a couple cars that just didn't seem worth it come by. Obviously I am looking for something that needs some work but is drivable. Saturday my dad woke me up telling me about this Honda with a five speed posted for 500 bucks 20 minutes ago, and I wanted to throw a shoe at him (short night's sleep.) The car was a 91 CRX HF that needed a hood, radiator, hatch glass, windshield, and a headlight.
We saw a couple of the goodies Saturday when we looked at the car, but this evening when we got it back to the shop the list of crap was inbelievable!!
Suspension:
Koni four way adjustable shocks all around, ~400 bucks
H&R Springs all around, ~200 bucks
SPC front and rear camber adjustment kit, ~400 bucks
Engine:
Non stock Japanese engine (per my brothers comment) its some D15, i wanna say D15B? The block is definitely not the stock block, and the valve cover says 16 valve on it, when the engine in this car is supposed to be an 8 valve motor. Maybe just a valve cover, maybe more.. will pop the cover off tomorrow and see.
Interior:
SI seats in acceptable shape
Black all around
Unused stereo adapter plug already plugged in!
NICE heavy chromed spoon 5-spd shifter knob found in smugglers bin in the back
complete interior! if you've seen the inside of a CRX you know its lots of pieces, and they are ALL there!
Visual:
Paint looks great
Passenger's side mirror, not stock on HFs
The vehicle has 390K on it!!! but the kid we bought it from said the previous owner had put a japanese crate engine that had abour 70K on it as of now.
He has swapped in an SI interior, which is all in nice shape.. the paint is in fair to good condition, a recent but likely cheapo paintjob. Little little bits of rust here and there but nothing serious!!!
This car was a STEAL and I am kinda thrilled about it.
Obligatory crappy cell phone pics:

you could always give BRAAP a heart attack and stick two 90mm Q45 TBs on it

Dear lord, that was just a current list, too.....
One thing I totally failed to recall when I ordered up my list.. the 72 that was given to a friend and ultimately rolled.. was rolled... While on a trailer! The truck, trailer and the Z all rolled off the side of the highway together. Don't ask me how, the car was in the hands of one of the sons of the family who shall remain nameless (because he is a member of the forum heh) and I am not entirely clear on any of the rest of the details.
It was fun remembering them all, though. I <3 datsuns.

Priceless! May the father of all Z shine down upon you my friend!
Hey, Carlin prayed to Joe Pesci.. I'll invoke the name of Mr K.

The Datsun wanted to be a Morgan!

you have to realize that this is not the forum to be asking for help on the level you are asking for.
HybridZ is not here to be a prop to your average Klick and Klack listener who spent $300 at sears on some tools and wants to change his own brakes.. I don't mean to belittle you or your problems (we all start somewhere and I am no professional mechanic myself) but what I am saying is that you ARE asking questions far below the level of this place.. not that you, your problem, and your expanding experiences aren't welcome, per se, but for the love of Katayama, don't take offense when people suggest you study your literature a bit more.

check the head pics and descriptions thread sitckied in this sub forum, there is mention of the N42 head there as "just about the only head they had in Japan after the E31, until the P-series" which means later 240 through early 280ZXs.
You have to dig, but it is in there. Its a good thread to read through.
-
Okay, you want the Carey Clan Datsun roster?
This includes myself, my brothers, my dad, and my uncle. I will start with currently owned/operable vehicles, then projects, then parts cars and past cars. Roadsters and Z-ZXs.
Curent S30s:
72 orange 240, owned and fully restored by my uncle ~1991, needing paint attention and minor engine work but mostly cherry, white interior, flared, three piece molded rear spoiler.
72 240 ITS car, full cage, owned by my oldest and younger brothers.
project-my 75, click "fusible links blow" in my sig for ALL the detail on that, currently on the back burner
My dad's 78 with ~45K on the odo, this car was near mint (being very critical when I say near mint) chassis/interior but had been a friend's turbo project from about 1989 on. Never really finished, probably because they didnt have megasquirt back then.
Parts car: 72 automatic rustbucket, needs to get stripped, chopped, and scrapped. Who knows, might wind up getting the top cut off and turned into something wild someday.. but probly not.
Past S30s:
70 240, my dad, "The Grey ghost," see S30 rat rod thread for details there.
72 240 DD, owned by my uncle, used well, used as a test mule for a couple years, GREAT car, wound up beaten down then beautifully (if only superficially) resurrected by a friend who rolled it, RIP
71 auto, sold by my dad to finance the grey ghost
78 bastardized into a 72: not sure WHAT wound up happening with this one, this was someone elses project that we picked up but was a total lemon. Got some brakes, an engine, wheels, you know the drill.
74 260Z, my oldest brother's second car (first was a volvo, so maybe the datsun counts as first) and ultimately given to me, but I never got it on the road. It was a HUGE project by the time I got it at 16-17, and it was totally beyond me at the time. This car went to the same friend who got the above 72 "mule;" he used it as a parts car to make his mule whole. RIP
....and my dad's 1972 240Z that is my earliest memory. Sunday mornings, sometime before my third birthday, when on occasion my mom left me home from church with my dad, he and I would gofor a ride in his car, drinking chocolate milk, apparently with I going "vroom vroom." Red with a hint of orange, this car was complete and beautiful. I and both my younger brothers at times rode in the hatch with an older brother or my mother in the passenger seat and my dad driving; this car EMBODIES "the good old days" for me. Car was totaled while driving 60mph down a rural one lane highway in NC, when a ten point buck jumped out of the woods on one side, off the hood, and back into the woods on the other side. Datsun met the ditch, and the dream was over. The hatch, the cylinder head, and i believe something else still survive in our parts hoard.. if memory serves his head is on the 78 car right now; it was a built head and went onto any Z he drove other than his turbo car.
Past ZXs:
82 NA, oldest brother (chris is his name) Car was ragged to utter hell by my brother. Picked up in good condition, she gave him about 80K of reliable service, at which point he decided to start driving it as hard as it wanted to be driven. This car became a pickup truck for him ultimately, then at about 230K the car was retired. The engine lived a strong life in aformentioned friend's 72 that got rolled.
83 turbo, my dad. Wow, how ignorant we were; we never should have let this go, even after the guy rear ended my dad. Incidentally, a trailer hitch I found in a junkyard (the hard way) may have saved the gas tank from rupturing during the accident.
81? NA owned but never registered by my youngest brother
86 NA owned and painted by my dad, beautiful Z31, champagne... umph. I miss this one.
86 NA owned by my youngest brother, engine blew one day on a test drive after he changed the front brakes. Go figger.
Now, for the roadsters......
Oh geez, theres no way I can remember (nor do you want to read) all the parts cars; all were 1600 or 2000, there was one 1967.5 low windshield 2000 in there, something like serial number 73, but it was a rustbucket. sold it to the guy who runs datsuns.org Other than that, just picture like, about a dozen different roadsters. I havent seen THAT many parts cars go through his hands... but he was at it long before I was around, so who knows.
Currently my uncle has a 69 2000 "hot rod/street car" project thats been simmering for 15 years or so. Its driven (been DD'd) in various manifestations, but never come close to being "done." He also has a 1600 DD, and a 2000 that was purchased with the intent of being a potential car for me or one of my younger brothers once upon a time. Not entirely certain how that car is holding up these days, and that probably means it is well into "parts car" territory now.
There is also his HSR 1600 roadster, and he just sold one of pete brocks 2000s to les cannaday for a restoration job les is doing for a specific customer who shall remain unnamed.
So currently, four roadsters as rollers and at least three or four parts cars in the yard now.
Throw in an 83.5 4x4 720 my uncle has always had, and a 74 B210 he used to have, and that about rounds out the collection.

I would seriously consider just getting the 300ZX harness and going at it like that.
If you are aware of what is involved in that upgrade, then it would probably be simplest to get it all done in one fell swoop. The schematics for the donor 300ZX, and the original chassis, would be the applicable references, but such a swap requires that the user (you) really be fundamentally able to take what you need from the two books and the two cars sitting in front of you.

envy, envy, envy, envy, and envy.
Did I mention I was jealous? I was about a week away from finding this thread and bumping it for updates, I've thought about it half a dozen times in the last week....

:burnout:
I like this idea, big block V6
I have a buddy who put one into a ~91 camaro planning to TT it some day. Right now (last I knew) it was all wired up using the stock truck gear, and it ran.. but that as about it, no interior etc on the car.Staying tuned.....
-
You are talking about the fresh air vent pull knobs. It is (when it works) one of the greatest features of this car, along with a few other make/models I have encountered. The only feature I can think of off the top of my head that is more special to me is the fact that you cannot lock your keys in the car
-
You would get better results if you posted some pictures of the window you have, and specify the year of your 240. Pictures of the door and window mechanism would be helpful, because it is possible that you have a later door (they will swap as late as 76) but an "original" piece of glass.
If you google xenon s30 you should find a website that has many different years' factory service manuals, there might be line drawings in them. I would include the 77-78s in your search just because the glass would be close enough in rough shape to try (I am putting myself in the PO's shoes, trying to imagine how he might have improvised) MSA or black dragon catalogs may prove useful as well.

"uploading training manuals" ---> Posting tons of s30 knowledge
"company server" ---> HybridZ.org
:)all hail the company server

I cannot recall the specific clearance, but you need to get a flat top pistons (even one with a relief cut in it, if needed) VERY CLOSE to the firing deck to obtain proper quenching from that combustion chamber. 1fastZ is the one who I know knows that figure off the top of his head, any time I want to get it exact I embark on a search that involves his name and P90. something like .021" or .21mm, i think? Not sure if that is (+/_) deck height desired, or piston to head clearance, so I know I am not much help there, but I wanted to point it out nonetheless.
Secondly, I am curious about the angle left along the circumference in the combustion chamber.. At the deepest point its almost like a wall meeting a floor, rather than say, an emptied out swimming pool used for skateboarding (reaching for an illustration here) There is no radius, instead a sharpish turn.. Any experienced head porters want to comment on that? It seems unusual, but maybe I am mistaken.
BTW the "short turns" are the short side radiuses (radii) in the ports. The "roof" is the long side radius, and the floor is the short side radius. The reasoning is, the circle that the arc of each wall would form has a certain radius, and the upper wall would form a larger circle.
If you do cut reliefs out of flat top pistons to achieve desired compression, just take a peanut shaped bit off-center reflecting the combustion chamber.
-
Look nice, kind of a roadster feel to them! I am not a huge fan of aftermarket gauges myself, but those are pretty sweet.
-
How did you "find out" the compression of the motor?? Compression check, corrected for barometric pressure, then reverse calculated? Asked the builder? To get a 9.5:1 compression ratio on the ozdat calculator, I had to set up a P90/F54 combo with a ~7cc DOME piston, or a subtraction of about 7cc from the combustion chamber. My understanding with the "P90 0.080 shave" is that you wind up with about a 42cc chamber rather than a 53, so it isn't the standard 80 thou shave job..
Could you be mistaken, and be at 8.5:1? That is a standard P90 with flattops...

I was called today and she can be mine for.........................$1000.
What you guys think?
I think you need to pass me Satan's digits, I want in on this bargain you've got with him......
Buy it, flip it, put the money into the other car. Be patient selling it, get it to good running condition first, and sell it for $3500 or more to someone at classiczcars.com.
Pour the money into your other car, or better yet, another car altogether..... Come on, You KNOW you've got that pact with Satan going on..... another car will come. 19xx?!!?!?! that HAS gotta be worth some scratch.

As soon as I pulled the crank out I realized that there was nothing there that was raising any eyebrows, it wasn't until I couldn't find the bottom end problem that I looked at the head. One of my valve clearances was about 0.080", wasn't tightened enough and let go at an autocross...
It was a GOOD lesson... Too much listening to other people's diagnosis, and not enough time formulating my own.
Any HARD engine problem (read: not fuel/spark related) gets a valvetrain inspection and a compression check in my book, just because you never know.
Wow, that sounds totally prickish and "I told you so!" but that was not the intent
hopefully the apology will make my intent clear -
The AC control unit is one, large unit that weighs, oh, around 20-25 pounds or so? The core in the heater box is about 10 pounds or so (plus water weight.) The dashboard, complete, is probably something along the lines of another 35 pounds or so?? I *may* be lowballing (if anything) and your equipment on a '77 *may* be a tad heavier than what I have held in my hands (semi-stripped late 260 dash, but I've handled numerous dashboards and they all seem about the same)
If you REALLY want to shed weight, the window glass and crank mechanisms are one more place to look. My two brothers pulled the window glass, regulators, and cut the interior door skin out, as well as removing the heater core from the box, and "some small wiring stuff" to the tune of 50 pounds.
If I have time and remember, tomorrow I will try to get some rough weights on 240 dashboards and the semi stripped 260 dash, as well as a clearer definition of "semi-stripped." Unfortunately, the only complete, 280 dashboards that the family has are installed in my 75, and my dads 78. BUT.. these ARE good questions, and I DO have a complete AC control unit that I need to pull out of my passenger seat to get the car off the trailer tomorrow.. we also have a couple complete 240 dashes, that semi-stripped 260 one, and a scale all already handy there at the shop, and one day fairly soon the complete dash will be pulled from my 75..... so I really need to make a mental note to collect all this data.
-
Wow. I read and understood the function of the BCDD about five or six years ago, when I first read through the EFI bible.. but it never *really* clicked in my mind because that was before my 3 year long affair with my Subaru, The Car That Taught Me Fuel Injection And Auto Mechanics. Now I know all about the practical upshoots of things like drop-throttle fuel cut, because I have been running the ECU's algorithm in tandem in my own mind the whole time I've been driving. (Pizza guy.. 500 miles or more a week?)
This thread just tied up the mental loose end there. Keep in mind that I haven't rotated a single wheel in an FI Z since my fire on 04, and everything has really been learned in practice in the intervening time..
But my question is this. Why are we feeding fuel to our engines on decel at such a high RPM?? Is there a lower threshold where we can set it? What determines the lowest threshold you can run no fuel, no throttle while coasting in gear??
As a pizza driver, these issues burn in my mind and soul often. The more thorough and detailed an explanation you can point me towards, the better; I understand most of it, its just that 2800/3200 seems AWFUL high, and I want to know why they set it where they set it, and what needs to change in order to change that.
-
le sigh... mine worked, until I tried to remove the bubbly tint from the glass..
Those were the days, I had just met the Z, we were young and in love (well I was 19, she was already pushin 30) and we had a clear view of were we had been, regardless of relative atmospheric conditions within and without the cabin........
-
I am going to guess maybe higher than that, but under 3000. I wouldn't bet any lower than 2800, but I am clueless on the weight of the motor/axle train (not a domestic guy)
But I have to ask, what do you mean by all aluminum flooring in the rear??? Also, any more thorough pics of the roll cage/T top setup (including the window seal at the top; IS there a pair of tops that go in there or is this a dry weather vehicle?)

VALVETRAIN NOISE??? WHAT VALVETRAIN NOISE, SHE SOUNDS GREAT!!!!!
NAW, SOUNDS JUST RIGHT, NICE LOPEY CAM, THUH-TUDDUHDUHDUHDUH
VIDEO WORKED GREAT FOR ME!!
*key*off*
yeah, I didn't hear any valvetrain noise.
