    In a VQ application, I would be concerned about the Quaife holding up, especially in an endurance application. I have heard these guys are a bit fragile under high torque/high power applications, and the repair costs can be substantial as you're sourcing everything from UK..
    Really? The VQ isn't making a ton of torque by any stretch. I'm just basic bolt ons and a conservative tune at roughly ~260whp. That's per the previous owner so I need to confirm that. Feels like it's around that range based on weight and lap times.

      Quaife are known to be pretty fragile. 260hp would be a stretch on them, IMO. Designed around lighter European cars that have small engines, low torque, moderate HP.

        There are spur and helical gear options (good for 750bhp and 375bhp as per quaife, respectively). Do you know which you or whoever had experience with?

          No idea.
          I looked at a 'rocket box' many years ago and the Quaife dealer said they were good for a little over 200ft lb before they start to break things and have wear issues.
          The biggest issue isn't the normal wear cycles, it's the one shift you miss every weekend or so that chips dogs or breaks a gear because your foot is in it and you got WOT into the wrong thing.

            The rocket box is a pretty small box for low power. I think the newer sequential offerings are quite a bit stronger than them, but I have no personal experience. They are used pretty often behind 250whp engines though.

              Production Core4 radial mount bracket proved out:








              NOT ONLY FOR DEFSPORT 2-PIECE ROTOR KIT...One of the best things about this bracket is that it can also run off-the-shelf Z33 track rotors (12.8" x 1.18") with the simple use of shims/spacers. You can get Centric Ctek Z33 track rotors for $30 a piece! Not sure you can get a cheaper, more effective big brake upgrade out there without worrying about chucking rotors after a few events.

              Z33 track rotor with Core4 radial mount bracket:

              Started working on grafting the 05 Dodge Ram hood bulge on the S14 hood. I don't want to get ahead of myself here, but it's laying up on the S14 hood REALLY nicely. Better than expected. It should definitely provide adequate clearance for the VQ IM with a 1/2" manifold spacer and the friggin hood should finally sit flush and not ghetto raised.

              Here's the first cutout and lay up:




              More to come shortly.

                Moving along with the hood.

                Fixtured up the hood with some angle where it mounts to the chassis to prevent excessive sloppiness once we cut out the area of interest.





                Ended up going with a butt weld joint instead of using a flange tool and making a lap. It seems that butt weld joints are the preferred method for sheet metal fab guys even though it's a bit more work to get it just right.



                Got the skin graft fully tacked in. Surprising how well the RAM cowl curvature matches the S14's:









                Next up is fully welding, grinding welds down flush, and working the sheet metal where it'll shrink from the welding to get it as smooth as possible before going body filler crazy.

                  Nice man! Have you done body filler work before? I personally hate it. I don't have the patience to sand

                    I'm the welder, my co-driver is the body filler Definitely something with required patience.

                    We really do want to try and make this nice enough to use as a plug for a mold so let's see how much patience we can handle ha! Decent amount of weight in the hood of these cars, even when gutted. Such a good spot to drop weight from.

                      That hood looks like it is going to work out really well! I think you got the better end of the deal being the welder & having your co-driver be the body filler.

                        Started up a group buy for the brake stuff. Don't hesitate to ask any questions if you have any.

                          Getting ready for a 4/9 test day. I took the risk of running no tender springs with my new, stiffer rates at my last test day in November and this is the result on a rear corner:







                          Did not expect that to happen to that extreme. Going through video you can actually hear the spring re-seat at about the 21-22 second and 26 second marks:

                          Click for video


                          That ushered the order of some tender springs. Getting tender springs setup piece meal is a more expensive journey than I had anticipated, but then I stumbled on these from the land of Miata:

                          https://supermiata.com/dual-spring-kit-xida.aspx




                          Two tender springs (150 lbs/in), two needle thrust bearings, and HPDE spring couplers for $115 + shipping. It's a great deal. The only caveat is that they're 2.25" ID, which not many S-chassis people run. Luckily, I had just switched to 2.25" to gain a bit more tire/wheel clearance.

                          'Murica....kinda:

                          Still got some forward momentum with the hood project also. It's fully welded and I've been hammering and dollying away on the metal near the weld seams to relieve stress and stretched metal relative to the heat affected weld zone. I've also been using a "shrinking disc" in between H & D'ing which has been nothing short of amazing for working the sheet metal and removing oil canning (sheet metal popping up and and down) and waviness. (Click here for what shrinking discs are and do). Again, I'm doing this to minimize the amount of filler that needs to be used. A heat cycled hood isn't ideal for filler by any means.


                          Fully welded up:



                          Passenger side weld seam after working it. Hard to tell how smooth it is in pictures, but it's night and day difference from how it was:



                          Here's the front seam area prior to me working it. Notice how different the crowns are between the Ram hood and S14:





                          After spending some time shrinking the metal adjacent to the seam to flatten it out, I then used a "slapper spoon" with some crown and hit from underneath and arrived here:




                          Worlds better. There's some slight oil canning going on after shaping it up so I'll need to do one more round of shrinking and and light slapping and it should be good to go. On to filler it goes after that.

                            Holy carp.. I was never good at sheet metal- definitely some art involved in that work!

                            When you're done, how about you make a mold of it and sell fiberglass/carbon versions?

                              I wish I knew about that disc a couple years earlier when I was welding my quarter panel area. Would have definitely saved a lot of time

                                I remember doing this with blowtorch and a wet rag. I think I only made lots of small humps out of big ones..
