Not much going on, waiting on parts and motivation.
In efforts to be clean, I didn't want to make due with the old throttle cable. The solution previously in the 280z was to obtain a 240sx cable of unknown vintage and bolt the OEM mounting plate it came with (which looked like it was cut out of the car it came from) to a random location on the firewall near the 280z throttle hole. This then enabled the cable to be fed inside the cabin where the 280z pedal had to be ruthlessly modified to accept a pull type cable end instead of the OEM heim-like joint linkage. It worked well, but I was always worried that it would break at an inopportune moment since installing the 240sx cable also involved excessive amounts of bending.
Firefox for the Mac only lets the tab size get so small before it starts scrolling in the same window. After several hours of searching I was able to identify the required OEM linkage piece, which I needed to connect to the piece that goes from the pedal in the 240z into the engine bay, as a bell crank. I was able to find used ones for sale from z car source in Arizona and they had great customer service.
I also broke down and decided to buy what was left to get the car most of the way to running in the way of parts from mckinney motorsports in California. They make a custom 240z/rb25 swap throttle cable that hooks to the above OEM bell crank. They also make a custom 240z/rb25 2 core, 2 pass radiator with hi-flow fan and shroud with the 240z mounts and rb25 input/output fluid port locations. I'll be downgrading from a 3 core unit but passing the fluid through twice as much. From what I've been told the core's themselves are very large and since it's aluminum it should be pretty light and a very clean install. I also won't have to run radiator hoses across the engine bay using a radiator that wasn't designed for the current engine's coolant passage positions.
I might as well get the correct fan and shroud at the same time instead of dealing with building one or trying to fit another and expounding more pain and frustration along the way as spending the money up front and just having it work the first time. That, and I want to drive the car. Their customer service leaves something to be desired, and apparently my gmail will not receive emails from Mckinney, but my bank account is sure in direct contact. I've heard great things about their parts and I'm excited for a clean, well designed and built product.
The 240z registration came through and the SC DMV promptly refunded my paid taxes for the 280z. Rad.
On a side note, anyone want to go to Burma for a hill climb?

close up
Car was finally delivered. Change in plans as far as the for sale page goes, TDC took the nx nitrous kit instead of the harnesses, possibly for their new drag car project. Who needs safety parts when you can have go fast parts, I mean come on. That and I was never seriously intending to use nitrous in any game changing way on the Z anyways. Ideas were bouncing around to use it as a intercooler cooler with a spray bar kit in the front, or maybe even a turbo spooler with a small shot in the low rpm range, or just set it up to spray drivers in the adjacent lane. Concerning raw power, however, anyone who's ridden in the car knows you're not left wanting.
Welding looks great. The bov was installed on the turbo side of the fmic, inside the bay on the lower pipe facing downwards instead of the upper facing upwards barely clearing the hood or fender (as you can see by the rub marks on it). There were discussions previously of placing it on the tb side of the fmic, in front of the core support on the intercooler connection, but it wasn't to be. It's ok, you can take beautiful combination picture shots with everything in view.

plumbing with ari at tdcauto.com
It's a big deal for me to take my car to a shop. It's nothing against shops, but usually if I want something done right, I do it myself. I am humble enough to know, however, when I can't do something as well as I would want, whether for lack of time, talent, or tools, sometimes it's better that someone else does the work. Yes, I said it.
I first met Ari one day when he came over to look at one of the Corbeau seats I was selling from the 280z. Someone else had already claimed the newer seat for 2oo$ so i figured 125$ would be good for the used one. We talked about 1oo$+ and he said he could pick it up later but didn't make it. On a side note, neither did the guy who claimed the other seat. I sold the pair to an *$&#^@! a month later. As it turns out, even though he first found me through a Craistlist ad, he was originally from my neighborhood and apparently still rides mountain bikes behind the barn I'm renting. So he's the one the neighbor's were complaining about making jumps in the woods near the lake. Ari mentioned he welded but I thought nothing else of it and a few months passed.
Dyno nights have been my occasion to frequent TDC Auto, spinning the rollers with my 280z just before taking her apart last winter. I knew a few people there, and heard good things from people who had work done there. Recently they hired a local welder named Ari who was doing their custom fabrication work. Unbeknownst to me, Ari was Ari. I didn't make the connection when talking with Chris about what I wanted, and more importantly how I wanted it.
Chris was enthusiastic about the project and set the as yet unidentified Ari to work immediately, with just a few emails, and what I'm sure was a mess of random instructions and requirements from our previous encounter. Price discussions would be made later, this project would be done, and done right. Since I was able to leave the car with them for a while, 4 weeks as it turns out, they were able to work on it in-between jobs during downtime to save $. Chris also took my harnesses and fuel cell from the 280z as trade which worked out well for everyone involved. I can't wait to see pics of the parts installed in shop cars!
After minimal contact over the first 2 weeks while I was incommunicado, I was very happy to come by the shop and see most of the work was already done. The old unibody was supported very carefully on the lift. The FMIC's end tanks and inlet/outlets were modified to line up with the, coincidental, 3" oem holes through the core support. The upper mounts were removed and a thin top plate would be welded over it to complete the super clean install. Stainless steel mounts, because of proximity to the elements, were fabricated to fully support the FMIC from its bottom mounts, hidden, utilizing oem threaded holes on the lower core support. Instead of snugly fitting thin-walled aluminum tubing through a core support that could easily vibrate a hole into it, longer silicone couplers were used to allow for some flexing and rubbing, in a good way. The joint was positioned so that I shouldn't run into trouble disconnecting the FMIC in the future as with the shorter couplers on the 280z, eliminating hours of entertainment from the many bumps, bruises, and cuts it took to remove clamps, using any wrench that would fit, effectively inside the core support.
The intake plenum was removed and the "oem" flange cut off, re-angled, and welded back on. I was told later that, and I quote, "It wasn't baller enough so he took it off and re-welded it again." TDC Auto rocks. Ari connected both sides of the short track of intercooler piping. The throttle cable mount was removed and relocated and a new throttle body was used in place of the stock Q45. This is a 9o mm Godspeed unit and is much cleaner. As you can see it's rotated 90*, as is the new mating flange on the plenum. Mounting the engine so far back in the bay has added to the complexities of the build, including having to re-orientate an aftermarket throttle body on an aftermarket plenum because it runs so close to the suspension column. At the very least it'll make the sensor wires easy to hide.
A new dump tube was made to replace the ugly old one. Instead of a 180* bend being created by welding several wedge-cut pieces of straight tubing together, an artfully bent/cut tube was fabricated and welded to the v-band. The exit is now more safely facing downwards below the engine as opposed to outboard under the framerail, and more importantly, not directly in front of the front tire. The bov was going to be placed on the charge pipe as marked, but we decided to relocate it to one of the bends coming off the FMIC. This would move the bov in front of the core support to the throttle body side of the intercooler, provide better response and less turbo reaction, while freeing up space in the engine bay. That and it's just cleaner. Maybe I'll have room for a cold air intake one day.
The downpipe was modified to fit the new engine position in the new unibody, as was the front half of the exhaust. V-band clamps were reused and the o2 bung to be relocated from it's now unusable location adjacent to the firewall, to the inside of the downpipe, just after the vertical drop near the headers. Eventually I would like to re-coat the downpipe, or maybe use some kind of header tape to insulate it. I would also like to add a heat-shield for the master cylinders directly adjacent to the downpipe, it's something I always wanted to do in the 280z, especially with all the wires in that area, which I plan to run on the other side of the firewall this time, away from the hotness that is the exhaust of an rb25.
I realized Ari was Ari when he came into the shop after lunch and I managed to kick over his drink while asking him to connect the go-pedal side of the throttle cable. I thought it was odd that he looked so familiar but knew something was up when he asked about the barn that I currently inhabit. The car should be delivered tomorrow and I can't wait to get her ready for paint and final wiring. Thanks Ari and Chris at TDC for doing a great job, hopefully I'll be able to come back for a dyno soon.
