3/7/13 Taking Care of the Details

As usual, it's been a while since my last update. I've been working here and there on buttoning up the details of my swap before I jump in and pull my engine. Right now the engine and mount kit are at CB's shop waiting for the car to join them. I'll run though the various systems in order.

First, the wiring. I got all of the wiring from the donor car, including the dash harness and key, but once I got a look at it I decided there is probably no way I'll be able to neatly hide all that wiring in the car. This, combined with the fact that I'll need to get it flash tuned for the mods I'm doing anyway pushed me in the direction of sending the harness to get cut down professionally and flash the ecu for my mods and to get rid of the security system that makes the dash harness necessary. I pulled the engine harness off of the engine last weekend. I'll likely be sending that out this week and when I get it back there will only be 4 wires to hook up to get the engine running. Can't wait.


The fuel system is also a little tricky. Obviously my car is carbureted currently. This means that it has small fuel supply and return lines, no electric fuel pump and no baffling in the tank to keep air bubbles from getting into the fuel lines. To get fuel to the engine there are two typical options. 
1. Get a baffled tank from a 75-76 280z, then buy a fuel pump, fuel pressure regulator and run larger lines to the engine. I would also need to modify the VQ fuel rail to make it have a fuel return(the system is returnless from the factory)
2. Keep the carb tank and to a surge tank setup. This would require a low pressure pump to feed the surge tank, a high pressure pump to feed the engine, a surge tank, fuel pressure regulator and lots of plumbing. I would still have to modify the VQ rail with this as well.

I chose a third option that I don't think anyone has done for a VQ swap before. I bought a 350z fuel tank and pump (which was HUGE). 

I cut out the mounting flange where the internally regulated, in-tank pump mounts. 


I cut open my Z tank

And I welded the new pump flange into my existing tank. 




This pump draws directly from where it mounts, and has a second line the goes to the other side of the tank to combat fuel starvation. The high pressure circuit draws from this built in cup that acts like a surge tank. This is setup to be a returnless system already, so once mounted I should only have to run one fuel line and two wires to get this working. Now that I have it welded up, the tricky part will be tracking down and sealing all of the pinhole leaks that will inevitably be along my seams, but once done this should be a good setup. 


I also have to modify my crossmember to clear the engine. I've already cut it open, and am waiting on some steel to weld it back.



And on a slightly sad note. CB has dismantled his car and sold his shell. He kept most of the components that are going into a new Z, but it is a bit sad to see the red car go.


The benefit of this to me is that I will be using his shop to do my engine swap, and that I'll be inheriting the 3" exhaust (with cutout) he just removed from the car, since he won't be able to use it with his new long tube headers. 

Still left on the list for the swap:
1. Rear end. I have a differential, and 280zx CV axles. I need to get 280z stub axles, CV adapters, and a 280z moustache bar. 
2. Driveshaft. Once I have the engine and diff mounted I can measure for the drive shaft.
3. Exhaust. I'm gonna have to modify the exhaust to fit the new engine. 

Getting there!

2/11/13 Collecting Parts

A few great things happened over the past couple of weeks. First, we finally got our containers moved. We're now on the north end of the navy yard with a much nicer view and no one demanding part of whatever company forms from this venture. Currently we only have temporary power, but we should be able to reconnect our breaker so an adjacent building shortly.



Next, I found another great deal on a mount kit for the VQ. Another member on Hybridz had given up on his swap I suppose and was selling the engine mounts, crossmember, trans mount and shifter relocation bracket for a substantial discount. So now I have that piece of the puzzle ready to go. I would have been nice to make my own mounts, but at this price it would have cost me about the same when all was said and done.


Electrically, the guy who I bought the engine from is sending me the dash harness and BCM from the same car so I should be able start it without having to pay for a harness service. 

That leaves fuel. I am going to try something new for the fuel system. I've ordered a 350z fuel tank with internal pump and regulator. I *should* be able to cut the mounting flange from the 350z tank and weld it into a clean, baffled 280z tank. This would mean that I only have to run one fuel line and two wires to get the fuel system setup, which would be wonderful. The downsides are that welding on a fuel tank is tricky, and getting the pump to be at the right height might be difficult, but I should be able to get around these problems. 

More soon hopefully!

11/26/12 Thanksgiving Week Progress

It was nice to finally have a long weekend so I could get some work done at the shop.

On the Friday after Thanksgiving I brought my triple Weber carb setup to the shop so I could do some wok on them. On the way there I spotted a future ideal home: a Manhattan brownstone with a private garage. Swap out the Porsche with a Datsun and you've got a pretty great setup for me.


Anyway, once I got to the shop, I set to cleaning up the last carb of the set. Webers are shockingly simple, but when you have them apart it looks pretty impressive with all of the components laid out for cleaning.


Once finished with that, I also replaced the curiously missing throttle return springs in the two I had built already for a full set of (hopefully) operational webers. I could only get the trumpets cleaned up but so much because they were rusty, so I'll probably have to order new ones eventually.




Afterwards I cleaned up the intake manifold. Starting to come together! Just for comparison, this is how they started out.




On my way home I spotted this 'Mercedes'



Saturday I brought the E31 head and most of my tools to the shop. It will be great to have a place to work again.

I also have some work to do on the G35 in the near future. The driver's side window has been acting up, so the motor either needs replacing or cleaning. I also need to replace a muffler gasket and throw on new rear tires for a possible sale...

Stay tuned.

8/18/12 Saturday Stroll

Went for a walk this morning before heading to do some car stuff. Luckily I've been reunited with AY's old DSLR.












Plus a hint of what's to come with my car.

6/26/12 Plans for the Future

Right now my car is slow. I never thought of it as slow when I had it in highschool, but I've owned and driven faster cars since then and I know I need more power. When I was at the track, I was able to pass very fast cars in the turns only to get blown by on the straights.

I had been planning on buying a new engine for the Z. I wanted either a 1JZ/2JZ, RB25DET, VQ35DE, or and LS1. The problem is that it's never just a new engine. It's an engine, a transmission, mounts, wiring, a new exhaust, new driveshaft, new gas tank for fuel injection, new fuel lines, intercooler on the turbo engines, and many many odds and ends just to get the engine in the car. This is not to mention that at those power levels I'd need to upgrade the differential and halfshafts. All this adds up to quite a bit of money.

Now I've decided to do this in stages. I'm gonna build a mild, carbed, 2.8 liter L engine to get me by in the meantime. I've worked out a deal with CB to get a head, triple webers, and a 2.8 liter block. CB is doing a much more aggressive 3 liter, ported head monster motor for his girlfriend's car, but I don't think that's a road I want to go down just yet. This engine should make around 180-200 rwhp if I build it right (compared with 250 or so for CB's stroker) , which would be about double what I have now and more than enough to make the car fun, and is simple enough to build in a couple of weekends. The main thing here is that because it's an L engine, I don't need mounts, a new trans, a new fuel system, exhaust, wiring and all that fun stuff. Just build the motor, tune the carbs and go. Not to mention they look and sound amazing!



As I mentioned before, there has been some progress with the new shop. As it stands now, JB and I will probably be setting up a couple of containers as a temporary shop while we try to get into a nearby building. Here is a quick sketch I did of a possible layout. It's small but it could serve until we get something bigger.


Not a big update, but that's what I've got planned.

And now, some interesting photos.

6/18/12 Massive Transition Period Update

I need to apologize for not updating this sooner. I guess I got a bit disheartened when we lost the shop in the Bronx and didn't want to write about it. Now, however, the next space is in the works (likely in Brooklyn) so I'm in a good mood again. I'll write about the new space when some of the details are ironed out, but in the meantime I need to catch up on the past few months.

When I last posted, I was finishing up some details on the car to get it road-worthy by the time the shop was to close. Coincidentally, I was signed up for a track day at Lime Rock around the same time. There were numerous little things that had to be done on the car to get it to pass the tech inspection at the track, namely I had to button up my fuel system, properly mount my battery, and figure out my seat belt situation.

T-2 days till Lime Rock:

 The fuel system was easy enough, I borrowed a gas cap from CB and reused the gas cap base from my car. I just needed to block off some vent hoses and tighten some hose clamps. On a run to the parts store, however I realized that the sound I thought was my alternator belt being loose was actually the water pump bearing failing. Luckily, I had just bought a spare engine (it was an L24, that the owner thought was an L28, but I took it anyway because it was just rebuilt). I hopped in the Miata and scavenged the pump from that motor and started installing it on my car. Around the same time CB came over with a buddy and they installed my gas cap/base.

I also needed to install my seat belts. The car came with seatbelts, but I didn't have a complete set. The ones from my old car were junk, and I couldn't use the racing harness I bought from CB because the track had a rule that the driver and passenger have to use the same equipment. I picked up a set of rear belts from a 240sx very cheap, and wrestled with my car for an hour or so to get them in.


T-1 day till Lime Rock:

CB had been struggling with clutch issues with his car for the past couple of weeks, and with one day left he was still having issues. I went to his house late and helped him put the trans back in his car for what we hoped would be the last time.

Lime Rock travel day:
We decided to drive up to Lime Rock the on Sunday for our Monday trackday. We had a connection with a local B&B and it was certainly the better way to do the trip.

That morning we had an early wrenching session to check the last issues that might pop up with the cars. I was tightening a hose clamp on my gas tank when the fuel return spout broke from its weld. This resulted in a  slow but noticeable fuel leak when stationary, and a substantial one when the engine was running. Panicking, we drained the tank and I drove to an auto parts store with CB. Twenty minutes and a tube of JB weld later we were in business.

JR also showed up with a proper battery tie down for me that he stole from his turbo car. About as long as I remember I had been using bungees and ratchet straps to hold my battery, and that would apparently not pass tech...

My left rear wheel bearing was still making a slight noise, but I checked the tightness of the stub axle nut and all seemed well so I just tried to ignore it.

It was a rainy drive up to CT. With the exception of an actual squealing alternator belt when the lights and wipers were on, the car performed perfectly on the drive. This was shocking to me considering that the car had driven about 20 miles in the past 35 years.

In the morning, it was frosty cold. The chokeless 240z started hard, but did start. We made a quick fuel run then got to the track just as the safety meeting was ending, in true Top Gear style. My car flew through tech and I was soon waiting for my instructed session to start.

After I had borrowed a helmet from JR, my instructor and I set up our helmet-talkies and headed out to the track. I have to admit I was a bit nervous, but it definitely helped to have an instructor in the car. I don't think there was any way I could have figured out the line on my own, but he did a good job of showing me when to turn in, where to aim and when to get on the gas. After a few laps I was starting to feel comfortable and getting on the car a bit harder. To my surprise, it performed shockingly well. Somehow, despite my eyeball alignment, it handled easily and controllably as as you approached the limit of grip. Once I stiffened up the illuminas, it even transitioned from corner to corner very flat and stably.

In my third session out, my instructor was pushing me to go faster and faster. I was actually passing the other cars on the track (mostly Porsche's as it was a PCA event), though many would retake me on the long front straight as I don't have very much power. Just as I was doing really well and going pretty quickly...I spun.

My instructor didn't see anything I had done wrong and seemed to be as surprised as I was about the spin. After a quick drive through of the pit lane to talk with the controllers about it, I was back on track. It took a couple of laps to get the confidence to go hard through that particular turn, but eventually it came back. The only damage to the car was a lost center cap to one of my wheels.

Unfortunately my spin did direct the attention of the corner workers to my car, and I was black flagged for some reason. It turns out my brake lights hadn't been working (this was probably true the whole weekend, but no one noticed until after I spun). In between sessions I did some electrical detective work to determine the cause of the fault and was ready in time for my last session, which went well and without incident.

In addition to Porsches, there was our club and some other serious iron. All in all, I really enjoyed the day and I definitely have the track bug. I also have the bug for more power, as doing all the work to pass a car in the bends, just to have him walk by me on the straights was frustrating to say the least. I think there is a 1JZ-GTE in my future...

Pretty much immediately after this event, the boys and I moved out of the shop. JB got a PODS storage unit and we loaded whatever we could in there. The rest of it went to my mom's house in Newark, including the 240z. It was a sad day indeed.

As a result, all work that I needed to do on my motorcycle has taken place in AY's building with the help of KY. I had been having an intermittent stumbling issue with the bike that I couldn't track down. It seemed to break up at higher speeds and when turning, so I assumed it was a fuel issue. In fact, I thought was was the same water-in-the-tank issue that I had before. One afternoon, I hopped on the bike to go fix it. Once I got there, I drained the tank, cleaned the tank and front plug drain tubes, and drained the float bowls. This did nothing. A later day, rode over again so I could swap the spark plugs. One the ride over it was running great.  I figured I should do the plugs anyway because they were past due. Did all the work and....it started stumbling again. Frustrated, I ordered new coils for the bike while I was away on vacation. Once I got back, I went to install them when I noticed that the bike stumbled when I turned the handle bars, even when I was stationary. I investigated and saw that the wire I had run to the tachometer of the Vapor gauge had been rubbed raw and was occasionally coming into contact with the frame...when the wind would push it back or when the handle bars were turned. I taped up the wire, re routed it and was back in business. Sometimes it's the simple things...

Around the same time KY was solving an issue with his friend's BMW Z3. This guy had bought 19's for his small car along with a set of lowering springs. As you might expect, it now rubbed it's tires pretty much everywhere. Even after removing the inner fender and massaging the hood (which is also a fender on these cars) it still didn't have enough clearance. The solution was to add a spacer between the upper spring perch and the body. Spacers were cut from 3/8" plastic and inserted, along with longer studs to clear the longer distance. This did the trick and the car can now brave the pothole-ridden streets of NYC without fear.

The only other time I've had my Z on the road since losing the shop was, unfortunately, for a pretty sad reason. One of the members of the New York Z club, Tommy Sullivan, passed away in early May when his house burned down, claiming the lives of his wife and two daughters as well. Tommy was able to get his son, Tommy Jr., out before going back into the blaze to try to save the rest of his family. In order to remember our friend and try to raise some money for his son, the local Z clubs did a cruise and sold T-shirts and stickers. It was a great day, and a memorial Tommy would have loved.



I know it's been a long time, but a new shop in is in the works so expect more regular updates soon!

3/15/12 Exhausting

With the Y-Pipe on, it's *a little* quieter so I ventured a little farther from the nest. I also Installed the driver side seatbelt for some safety. The car felt good. It really does seem to handle tightly. I did a couple hard brake tests and it seems that I don't need a bigger brake booster, as locking the wheels was no problem. That said, I do need to bleed them a bit better, as my left front locked far before my right front and I need to adjust my proportioning valve as well. but these are details.

I drove the car to bruckner and grabbed dinner. Also noting my electric fan and thermostat worked exactly as it should. Man it looks small...

Tomorrow I'm going to CB's shop to borrow his lift to install my exhaust. In preparation for this, I *ahem* modified the exhaust I stole from one of his parts cars. Here the tried and true Mike Fiesta method of making a generic muffler sound good. Mike and I did this to the muffler on my old car way way way back in the day, and the thing had the perfect amount of rasp. 

Step one, cut a flap in the muffler housing.

Step two, expose the innards.

Step three, remove innards.


Step four, weld shut.

That's it. hehe

Stay tuned for the results.
