  1. I was mainly looking to get a differential with a lock and capability to take a serious amount of torque. I was also intrigued by the more modern double wishbone type of suspension setup which offers very good adjustment options. There is also at least a theoretical benefit over macpherson in terms of keeping the camber gain negative throughout the whole suspension travel whereas in the macpherson strut suspension, the camber gain turns positive with larger outwards travel.
  2. Yep, it is an R32 subframe. I went about the fitment by gradually cutting off more and more of the original sheet metal from the bottom. The task was quite tedious, due to the fact that I wanted to retain the original GTR32 suspension geometry with the control arm angles so it meant fitting the subframe quite deep into the 240Z body. I've seen others fit the subframe much more to the surface. The car will be RWD.
  3. About the feed through hole on your motor mount. The material thickness on the mount seems adequate so I would not bother to try and dimple it. Also, due to the thickness, it will be a pain to dimple anyway. I would maybe increase the diameter of the hole for a bit just to make sure that the sharp edge of the hole does not eat into your oil return line. If possible, you could even make the hole big enough to fit a through hole grommet in between. Your intercooler looks like a nice fit. Is that an off-the-shelf model? Are you able to run the 90 degree angled rubber piping through the stock openings or did you need to cut them bigger?
  4. Thanks for asking. I worked on the car quite regularly until end of 2016, but then life happened and the project was pretty much on hold until beginning of 2020. I am still working on it so I guess this one of those never ending projects. The progress is documented here:
  5. The BMW V8 with overhead cams and the 180 degree exhaust manifold is so wide that the steering axle rubber joint does not have enough room at the upper end of the axle so I decided to flip the axle the other way around and move the rubber joint to the bottom. This obviously meant disassembling the universal joints. Luckily I was able to source a new set of joints as they did not actually dismantle very easy, required the use of a hydraulic press and got damaged during the process. I am quite happy with the outcome although I still need to finish the parts off with some fresh paint. The first picture illustrates the situation where the axle has not yet been modified. It is quite evident that the rubber joint would not fit. Before dismantling the joints... Afterwards - everything back together with all new joints... This is how it looks like from the bottom with the engine and exhaust piping. Extension axle from the steering rack relocates the bottom joint to the other side of the motor mount. I also added an extra support with a bearing due to the remote location of the joint. The new configuration can be more easily viewed without the engine.
  6. As the GTR rear hubs are 5x114.3, I needed a five lug conversion in the front. The plan is to also move the brake discs on the front side of the hub. As I was not sure about the rim offset measurement I finally want, rather than going all in with some billet aluminum hubs, I decided to make the first version by converting the existing hubs. I acquired a set of bolt pattern conversion spacers made out of aluminum. First thing to do was to machine a centered surface to the cast iron hub on a lathe to firmly seat and position the spacer. Unfortunately I do not have a picture of the machined surface. Then I sand blasted the hubs from the back side and painted the hubs in black. Getting everything to work required also machining some custom washers and nuts on the lathe. While I was at it, I assembled a set of new wheel bearings. The PO had customized the strut towers to accommodate some Tein adjustable coilovers a few years back along with other custom adjustable front suspension parts. I just sandblasted the parts and applied some paint.
  7. It's been over a year since my last update. Here we go! Once the engine bay and bottom paint job was done I sprayed some rock guard on the bottom and ran the brake lines and fuel lines in the tunnel. Then it was time to assemble the GTR rear sub-frame, but only after renewing the bushings and sandblasting and painting the sub-frame.
  8. At least from this angle, not ratty at all. Very nice looking car. Congratulations! 👌
  9. Thanks for the detailed pics. Seems like there is very little clearance to the headers. Does everything clear even when the engine is under load? You must have very stiff bushings on your engine mounts If there is no hitting.
  10. Well, as many times is the case with these kind of classic restomod project cars, they don't see a whole lot of miles. So I cannot say whether it is bullet proof, but it is the right stuff for the particular environment and designed to endure oil on the surface.
  11. This tip does not help If you have leaks on the gasket seam due to warping, but otherwise, If you have a leak on a welding seam, you can apply Glyptal engine internal red enamel. It is intented to close any porous on the internal walls of an engine block. Also works on the oilpan internal surface since it can endure oil and temperature upto 130 degC. I once sealed my modified steel oil pan with that stuff, when it was leaking from a welding seam.
  12. That is a nice pan. Was there any warping of the gasket surface area due to the welds? I need to do something similar on my build, but the BMW OEM pan is aluminum and I'll probably use more than just the gasket plate. I did some minor modification on an aluminum pan in my previous build and the gasket area warped to the extend that I needed to machine it straight. And this happened even though I had the pan firmly bolted on a metal table while welding.
  13. It's been waaay too long. It is over two years since I've worked on the car, but I finally found some time after finishing our new house and garage (to the point that we were able to move in anyway...) Actually, I needed to make some shelves for my garage and got some rusty old industrial shelves for free. They needed sand blasting and painting so I decided to do the 240Z "on the side". Of course the work on the 240Z ended up being the more time consuming task, and the Wife also expressed herself on the long hours at the garage. Anyway, the very tedious process of sand blasting the shell to remove all the surface rust from all the welds, spraying the first layer of epoxy, seam sealing everything and finally spraying the second layer of epoxy (in black) to the bottom, to the interior and to the engine bay is finally done! May the pictures speak for themselves:
  14. What I've come to understand from work dealing with filtered air cooling systems for electrical cabinets is that a fan has a hard time sucking air through a filter, which is basically the same thing as pulling air through a radiator. Also, while axial fans are capable of producing the same amount of air flow as radial fans without restrictions, the situation changes quite dramatically when a restrictive element such as a filter is introduced in front. In this confuration, the radial fan is the winner in terms of air flow.
