Six_Shooter's Money pit/Time Vampire
I bought my 1973 240Z from a guy in Richland Washington that had bought it with the intent of installing a SBC, but decided it was too small for him.
So after a couple months of flying out to see the car, finailing the deal, and getting the car shipped I had my 240Z home, and in need of some TLC to get road worthy.
It was a less than typical 240Z, brown (eww), Butterscotch interior (double Eww), and Automatic (tripple eww)! But it was solid underneath, and I got a good deal on it.
The first thing I did was swap out the brakes, since they were in desperate need of repair.
I decided on going 4 wheel disc, using Toyota 4 piston front calipers, and 280ZX rear disc set-up.
I also had some electrical repair work to do, to get everything working right.
The only pictures I seem to have of the exterior are after a couple months of driving it, so there are some changes that I had already made.
I had already added the Spook by this point.

Here is a picture of the rear, that I believe I took on the day I got it on the road, due to the old tires being on it, the mudflaps and a box of spare parts in the back, that came with the car when I purchased it.

Tranny
Well after driving the Datsun for a month in auto tranny form, I got sick of not using my left foot, and just resting my hand on the shifter, though I had been shifting it manually...
I had also been able to locate the rest of the parts I needed, to complete the swap.
I started the swap about 2 PM on a Saturday, and had most of it done by about 8 PM, just a few details I couldn't finish in the dark.
Sunday came and didn't have much time and spent most of it trying to find a nut to install my solid front diff mount, which I could find and re-surfacing the exhaust flange to eliminate the exhaust leak I had there. Then family obligations meant no more time to work on the Z.
Monday I re-installed the exhaust, checked everything over, and then took it out for a drive. A manual Z is one billleeeeon times better than an auto Z. :D
I'm using a Centerforce Dual Friction, and it grabs HARD!! The tires screaming for traction going into 3rd made that apparent.
I was actually enjoying the L28 that's in this car, the auto just made that car a real dog, a real slow dog.
This tranny was a 4 speed, since I couldn't locate a 5-speed at that time.
On to the pics:
Not enough pedals:

Ahhh, that's better:

This shifter only moves forward and back:

This one also moves side to side.

This is where/how it was done:
http://sphotos-c.ak.fbcdn.net/hphoto...18998616_n.jpg
Now I have a manual Z, just like it should have been. :D
EFI and Turbocharging
When I first got my 240, it had Weber down draft carbs that had seen better days.
Here is the engine pretty much as it was when I received the car:
http://sphotos-f.ak.fbcdn.net/hphoto...65434937_n.jpg
Well since I'm a fan of EFI and turbocharging I decided to play with the engine that was already in the car, which turned out to be an L28, F54 block, with a P90 head, N/A version from a 1981 or 1982 280ZX, is as far as I can narrow it down.
I started with an N47 intake, which I cut off excess parts and smoothed out, it was also modified to accept "O-ring" injectors, which are more common than the stock "barbed" injectors, and many more sizes available.
http://sphotos-c.ak.fbcdn.net/hphoto...39155043_n.jpg
http://sphotos-g.ak.fbcdn.net/hphoto...93285068_n.jpg
I also had a throttle body adaptor made to use a GM 3400 throttle body. This is a 56mm TB and would also serve to house a compatible IAC motor and proper range TPS.
http://sphotos-c.ak.fbcdn.net/hphoto...37115489_n.jpg
Onto the turbo and exhaust:
I used a stock L28T exhaust manifold, and mated it to a Borg Warner turbo, pirated from a 6.5L diesel. This required the use of a small spacer between the manifold and turbine inlet. The wastegate actuator started as an actuator from a Pontiac Sunbird turbo, combined with some custom brackets and arms, it now controls the internal wastegate of the BW turbo. I chose that actuator, because I had one and it also opens at about 2 PSIG, giving me a large range of control over the pressures I am able to set. (Though I had to add external springs to get more than about 5 PSIG of intake pressure.)
http://sphotos-g.ak.fbcdn.net/hphoto...61353545_n.jpg
the exhaust is 3" from downpipe to tip. All fitted and TIG welded by yours truely. :D
http://sphotos-e.ak.fbcdn.net/hphoto...34444017_n.jpg
Muffler, a Moroso Spiro-flow and tip:
http://sphotos-d.ak.fbcdn.net/hphoto...25923580_n.jpg
Turning attention to the ECM and wiring:
I first had to chose a place to come thorugh the firewall with the wiring. I used a stock firewall feed through ("grommet" ), from a 1988 Chevy Cavalier, since it was part of the harness I already had, prviously installed in my 1985 GMC Jimmy, that had a turbo 3.2L V6.
http://sphotos-b.ak.fbcdn.net/hphoto...20532701_n.jpg
Here is the ECM, which is in it's "easy to access" location. You can also see the grey "EMU cable" that attaches to my EPROM emulator to allow real time tuning.
http://sphotos-h.ak.fbcdn.net/hphoto...26869377_n.jpg
I use a custom code called "Code59", which is a modified version of a stock GM code called "$58", which was originally used in the Syclones, Typhoons and Turbo Sunbirds. This allows for Wide Band O2 fuel control, extended VE and spark tables (up to 30 PSIG!) and many other refinements that the developers have done and they plan even more! (www.code59.org for more information.)
Working on the wiring:
http://sphotos-g.ak.fbcdn.net/hphoto...69055115_n.jpg
(Mostly) Complete harness:
http://sphotos-b.ak.fbcdn.net/hphoto...26478010_n.jpg
Fast forward to a running installation, which didn't have an intercooler, since I ran out of time, seeing as I got running the day before 2008 ZFest, and had a few other details to iron out. I had to turn the TB upside down due to the dizzy cap interfering with the TB linkage. I didn't really mind this since I was already planning on a DIS swap later on. (more on that later.)
http://sphotos-b.ak.fbcdn.net/hphoto...59178689_n.jpg
http://sphotos-g.ak.fbcdn.net/hphoto...31596415_n.jpg
I've skipped over a lot of details, like modifying a 280Z speedo to accept a GM optical Vehicle Speed Sensor, oil supply and return for the turbo, modification of the throttle pedal to use a GM throttle cable from a Buick Century (IIRC), using a GM ignition control module between the 280Z dizzy and the ECM, E-fan install, electric fuel pump and larger fuel pick up from the tank, along with many little brackets and adaptors to make it all work together. I also swapped in a 5-speed from a 1981 280ZX that I bought for parts in this time.
I was able to get it tuned and work well up to 10 PSIG, but the weather was turning cold and time to park it for the winter.

Re: Six_Shooter's Money pit/Time Vampire
I decided to take the 240Z apart to do some up grades and other planned changes, but since my garage wasn't insulated (working on that), I didn't get a whole lot done when it was cold out, and then everyone wanted to me work on their vehicles (along with house hold chores), put the 240 on the back burner.
I had been able to get the DIS conversion almost done, just some wiring to the ECM and power are all that was left at that point.
I already had some parts that could be used for this conversion, due to needing to make an external crank position trigger system for my aformentioned GMC Jimmy. I retained the reluctor wheel and part of the CPS bracket, along with the ICM and coils.
I started by having my grandfather (A retired machinist) redrill the reluctor wheel to fit the Datsun harmonic balancer. I then went ahead and made a new base for the CPS mount, with some adjustablility built into it. ;)
http://sphotos-e.ak.fbcdn.net/hphoto...15531917_n.jpg
http://sphotos-f.ak.fbcdn.net/hphoto...59680245_n.jpg
Some of the parts:
http://sphotos-e.ak.fbcdn.net/hphoto...78013297_n.jpg
The only glitch I've had was getting the stock (280Z) tach working with the DIS.
The tach, which I installed last year, worked with the dizzy set-up connected to the negitive side of the coil.
It seems that the output of the DIS module is too weak to trigger the 280Z tach (works fine with an Auto Meter tach), so a resistor needed to be bypassed inside the tach, now worked fine, until I hit about 5000 RPM, at which point the tach would either peg, or drop to zero. After doing some reading, I think this was due to the dwell of the tach signal getting too short at upper RPM for the tach to read correctly.
I got tired of the ECM sitting on the floor, so I found a place to mount the ECM, so that I could take passengers, and not worry about them kicking the ECM or cables.
The Brackets, which are made from textured ABS sheet:

Attached to the ECM:
http://sphotos-c.ak.fbcdn.net/hphoto...31894714_n.jpg
I cut the MEMCAL cover to allow for the EMU cable to come out of the ECM without being pinched:

Details of the ECM mounted:

And finally, the view the passenger will have of the ECM:
http://sphotos-d.ak.fbcdn.net/hphoto...07713027_n.jpg
Interior
In the time I've had the 240Z, I've had a few gauges set-ups in.
Obviously I started with the original gauges, then I swapped the Amp gauge to a 280Z Volt meter. Swapped the 240 tach for a 280Z tach.
http://sphotos-c.ak.fbcdn.net/hphoto...72178839_n.jpg
I then wanted more information on my dash I swapped to this:
http://sphotos-d.ak.fbcdn.net/hphoto...43225449_n.jpg
I modified a quad gauge from a Turbo Sunbird GT gauge cluster, to fit into an original tach housing, this gave me, Oil pressure, Volts, Water Temp and Fuel Level. I then installed my boost gauge, a 2" tach and my AFR gauge into the trio location.
http://sphotos-b.ak.fbcdn.net/hphoto...09060438_n.jpg
http://sphotos-h.ak.fbcdn.net/hphoto...77146387_n.jpg
I found that I really didn't like the small tach, part of that might have been due to the poor illumination of it, good thing it was a cheap tach to test the theory. The LEDs that I installed in the small tach (as seen here: [url=http://sphotos-c.ak.fbcdn.net/hphotos-ak-ash3/76000_10152586608765051_147084713_n.jpg[/url] ) were too far out of my peripheral vision to be useful, at least during the day.
I decided to pull the rest of my Auto Meter gauges out of retirement, I Left the boost gauge where it was previously, I then installed the Oil Pressure and Water Temp gauges where the other trio gauges were. I gear clamped the volts and AFR gauges to my steering column and sat my fuel level gauge in the pocket left by leaving the fuse panel cover out of the car. I got sick of this ratty look, and decided to remove the radio, to install the 3 "loose" gauges into that location. I had other audio plans at the time.
I retained the 280Z tach for a while, then decided that I needed something that will keep reading above 5000 RPM, so I borrowed a Pro-Comp 5" "tattle-tale" tach from my Grandfather, that isn't being used in any other project. I installed this where the original tach would have been, and it fits snug, without any retaining hardware. I also installed an Auto Meter Shift (which is now triggered by the ECM), on a custom arm above the tach, on top of the dash.
http://sphotos-d.ak.fbcdn.net/hphoto...34814666_n.jpg
http://sphotos-f.ak.fbcdn.net/hphoto...78654295_n.jpg
I am now looking for a new gauge set-up for a few reasons. According to my datalogging program, and my known thermostat temp, the water temp gauge reads about 10 degrees low, this is an annoying quirk to me. The Boost gauge might read about 2 PSIG low, but there is some question to the accuracy of the datalogging definition file in this specific data output, so I will need to do some other testing before I condemn my boost gauge. I also want a gauge set-up that illuminates the font, graduations and needle directly, instead of the "flood lighting" that the early Sport Comp gauges I have now uses. I also want a radio again, the iPod and computer speakers just aren't cutting it, and as a Car Audio/Electronic Accessory Installation Technician, I should have something better for sound in my car. ;)
I may go back to the Quad gauge where the tach was, and install a digital tach/shift light above the dash or in one of the trio gauge locations. I also have a couple other ideas.
Suspension
I have made some suspension changes, which include Tokico strut inserts, a solid front diff mount and aluminium torque arm bushings.
I have mostly suspension changes planned for this winter, along with getting to finishing off making the FMIC, relocating the air filter outside of the engine compartment and a few other changes.
Misc
Here is a picture from the track, before I turbo charged it.

Re: Six_Shooter's Money pit/Time Vampire
Here are some pictures of swapping from an R180 rear diff to an R200. In this post there are also some pictures of the 300ZX CV shafts that I installed at the same time.

The gears, new timing chain, and maybe the new filter have really changed the way this drives, it needed a new tune, pretty badly.

Re: Six_Shooter's Money pit/Time Vampire
I received it March of 2008, I paid for it February of 2008 and found the listing for it in January of 2008. I had it shipped to me, from Richland Washington, which is about 2500 miles away.
So, yeah I've had it for a little while, but not that long to me. I had hoped to be farther along in the project by now.
I'm hoping to get some new pictures in the next couple of days of the FMIC installed and some other parts.

Re: Six_Shooter's Money pit/Time Vampire
Well, the car has been jackstand racing for a while, and I'm finally getting somewhere with it. The rear brake and 5 lug swap is nearly complete. I turned down the rotors from 290mm to 280mm tonight to fit with the brackets, caliper hangers and calipers I have on hand. I'll have to measure the old rotors, but I think that's still an inch larger than the old ones.
The front is almost as complete, but ran into a slight snag with the flex lines. The lines I was planning to use are a few days to get, and would be coming from two different warehouses. That means with my luck, I will only receive 1 of them by next week. I'm trying to get the car together again for the 24th, since that's the Brantford Downtown annual car show. So I'm looking at alternate flex lines to use.
Piktarz suun.

Re: Six_Shooter's Money pit/Time Vampire
Well, I found one issue tonight, when I had the car on the hoist...
My right rear wheel was rubbing on the spring perch of the strut. :/
It seems that all of my test fitting was done with the wheel that has ended up on the left rear of the car, since it was a narrower tire (same size in numbers 225/50/16), but the rest of the tires were wider at the sidewall.
So for a quick fix for now, I bought some 5mm thick spacers.

Hell must be a bit chilly this evening...
I started to do some body work on the 240Z....
Well, even what I did would still be considered more on the modification side than repair....
I filled the antenna hole and filled the driver side 1/4 vent hole. I didn't have to time to do the passenger side yet, either I'll head back later and do it, or do it tomorrow night.

Pretty cool Ol Z under that Nasty paint and rust! :innocent2:
You know your on the final streatch when you start doing body work and paint. :thumbsup:
I've had my 73 Scout for 3 years now and so far I have changed the oil, washed and waxed it, put on a soft top and driven it 600 miles. It is bone stock with 66K miles. Never had a stock vehicle in my life. So far I have collected a four speed close ratio trans for street with a 2 speed Dana 20 transfer case to replace the single speed transfer case and tree speed. 2 sets of bucket seats, one high back one low back to replace the bench (that is origanal and perfect) dana 44 to replace the dana 30 front end, power disc brakes to replace the manual drum, power steering to replace the manual, stock AC system, stock title wheel, 4.0L HO head and a 2002 aluminumtuned port MPFI intake for the 358 six cylinder and a few other things. Been afraid to ruin the value. Then being broke and book is between $10K and $15K I put it on eBay starting at $4k and never got a bid... so the hell with stock value I am starting to redesign it the way I want this week it begins with Power Steering!!!! Guess I will have to start a build thread!

Re: Six_Shooter's Money pit/Time Vampire
Oh this isn't home stretching... far, far, far from it.
Eventually the car will be torn down to the basic chassis, put on a spit and a bunch of reinforcement added, along with a bunch of parts changed.
I'm only starting the body work, because the way it looks is really starting to get to me. lol

Re: Six_Shooter's Money pit/Time Vampire
We have a '78 280Z that is the original black, which we think makes it a Black Pearl, but we're not sure. I doesn't have the Sports Appearance Package, but from what I have read some were optioned without it. We don't know what to do with it. Would like to sell it as we have more than enough projects on the list. But I think an LS-whatever would be a good swap if I had the money.
-
Re: Six_Shooter's Money pit/Time Vampire
Uhg, I hate the LS swaps...
There are a LOT of LSx swapped S30s...
It is rather boring...
Much like the SBC swaps used to be... In anything...
Adding the turbo and EFI to the L28 is MORE than enough power and torque for these cars. That being said I will be swapping to a V6 that I hope to make more power with, but that's only because I can.
If I just wanted a driver, to have fun with, I do exactly what I've already done.
-
Re: Six_Shooter's Money pit/Time Vampire
Yeah but just like there were plenty of left over 350s years ago, then all the high performance parts came around, the time is now and for the next 10 years there will be plenty of LS motors all over the place. The 350 era is over and LS era has begun.
I like what you did to the motor. Unique! :thumbsup:

Re: Six_Shooter's Money pit/Time Vampire
I don't think I've mentioned it, but I had a boost problem. It seems I probably had this problem longer than I realized.
I noticed it earlier this year, when I tried to turn up the boost from 12 PSIG to 15 PSIG, that it stayed at 12 PSIG. :confused:
Checked a few things over, eventually wired my wastegate closed with some mechanics wire, but the problem still persisted. I knew the mechanics wire wasn't keeping it sealed, but it seemed to hold it almost closed, enough that I figured it would allow boost to build higher than 12 PSIG at high RPM. I had been considering that my couplings between the turbo and TB might be leaking, or the IC was leaking from somewhere, thinking that maybe the turbo really was too big, but then it should have spooled to the 5 PSIG even later. :mad1:
Apparently, it wouldn't and after installing a heavy spring on the wastegate tonight, I pulled out of the driveway at work, then hit the gas in a slightly spirited fashion, I happened to be looking in the direction of my boost gauge, when I saw it spring around to about 12 PSIG and my shift light came on!! :confused1: It never did that, it just kinda slowly climbed up to that point, and it took a fair amount of time to get the shift light on, even in first, this was almost instant. Woo-HA! So I drove around a bit and checked to make sure that was actually the case.
Let me tell you 15 PSIG of boost on this 2.8L is a phenomenally fun. THIS was the reason I put the turbo on this car. I was seriously considering my planned engine swap for this winter, even though I didn't really have time for it. I've just been disappointed with the performance of it recently. It was still decently quick, just not that hard hitting surge of power I've been trying to get.
Now... OMG, so much fun, hard hitting, slam you into the seat, everything goes to a blur fun... :rockon:

all that and it was just a spring?
You still getting enough fuel with all that boost that's working now?

Re: Six_Shooter's Money pit/Time Vampire
Yeah, the wastegate was being pushed open by the exhaust pressure. Which isn't really that surprising, since generally, exhaust pressure in a turbo vehicle pre-turbine is usually around 2 times the intake pressure. So that means that exhaust pressure would be around 24 PSIG with the 12 PSIG intake pressure, and around 30 PSIG exhaust pressure, when intake pressures hit 15 PSIG. The wastegate actuator I used is pretty lightly sprung, so it doesn't take much pressure to push the wastegate flapper open. I did have a spring on it before, but it appears it was too light and allowing the wastegate to crack under just exhaust pressure. The new spring is much heavier, and seems to be holding the wastegate closed up to around 15 PSIG anyway. I'll have to plug in the laptop to see what the wastegate duty cycle is to make sure it's the ECM controlling the boost and not still just spring pressure.
The fuel I'm not 100% sure on, I wasn't really paying attantion to my AFR display at the time. :innocent2: I know the VE table looks good up to that point, probably on the rich side like it is below that boost level.

Re: Six_Shooter's Money pit/Time Vampire
So what was AFR?
Rich is good! that way you still have a motor left to tune!
A freind of mine in childhood got a brand new 240Z on his 17th birthday 1978?. Or was that a 260Z? His brother was 17 the year before and got a used 1969 Ram Air GTO... he was showing me how fast it was, when he shifted to second he should have been stopping for the stop sign... that was my first accedent as a passenger... totalled a showroom condition GTO. it was actaully fine from doors back... same with the other car, no one was hurt... the cars met in intersection right front bumper to left front bumper... then we changed direction and I was face to face with the girl driving the other car...
I had to go back to NJ for my sisters funeral 2009 and found him still driving the Z. Never had another car in his life.
