  1. I am doing a similar conversion on my 260z. I am however going with a vk45 v8 out of a M45, and R34 GTR suspension and drivetrain. There rear subframe is pretty simple to do if you have knowledge in fabrication. I cut out the rear storage units and the rear floor section. The front is much more difficult, because the skyline subframe is much wider then a z. I completely cut off the front clip and made wider frame rails. I then cut out the flooring, trans tunnel and frame. Its quite a big job to do. Ill post some pictures later on of my build. Here is a good thread to go off of for the rear subframe that i kind of copied: http://nissanroadracing.com/showthread.php?t=3599&page=5
  2. http://www.ebay.com/itm/QUARTERMASTER-HYDRAULIC-THROWOUT-BEARING-STOCK-CLUTCHES-/290297530418 Ive seen alot of people use this. You may need to make a spacer behind it to fit correctly. Also, you would need to check the diameter of the output shaft to make sure the tob will fit.
  3. I am going to do a vk45 swap on my my 280z. If all goes to plan, I will be making the car AWD. Using a combination of r32 and z32 parts. I have done exstensive work suspension wise to make the car handle the power. Basically made a complete rear subframe and a arms using 300zx knuckles, diff, and coilovers. For the front I am using GTR knuckles and spindles. I have the fabrication part of the rear done, but hopefully finishing up fab work for the front in the next week or two. Once the fab work is done Ill make a thread though. What part of SOCAL do you live in? Im in north orange county.
  4. How is the clearance between the engine and fire wall using those mounts? Is it pretty close?
  5. It replaces all of the bushings in the rearend. The full tilt boogie racing bushing kit includes all of the bushings for the rear end. These bushings are made out of delrin. Which is a hard material that somewhat resembles plastic but can taking much more of a beating and doesnt allow much play. I personally dont think this setup in our s30's would work very well, but I was simply giving the OP other options. Which is why I am going with a full custom setup rather then trying to adapt and entire rear clip. I am simply just using the differential and knuckles from the 300zx and fabricating the rest myself.
  6. I actually have a mustang I did the IRS swap on. Its not the halfshafts that make the rear end not able to handle power. It is actually the bushings in the rear that make the halfshafts break. What happens is that the stick rubber mounts allow alot of movement of the diff. This causes the axle joint angle to severely increase causing alot of strain on the joints during hard launches. The actual axles can handle alot of power. Ive seen people put 1000hp onto those stock axles after replacing the bushings without an issue. However, I have seen people put in those "1000 HP" halfshafts and break them with 500hp. The full tilt boogie kit is your best bet. the mms setup comes with alot of urethane bushings which wear out easily under large stresses. Also, it may seem hard to grasp, but the hard delrin bushings in the ftbr kit actually give a better ride the the softer rubber bushings that come stock in the cobra IRS. It is because it eliminates binding which eliminates the rebound the rubber bushings produce. Also, this will increase handling tremendously as it will remove all the play in the setup. I also just bought an S30. I am converting it to a double wishbone setup aswell, but it is completely custom. I am using z32 components and making a cradle to hold the diff and lower control arms. I am then mounting the upper control arms to the frame rails that are already there. Ill make a thread later on this week when I hope to finish up alot of the fabrication.
