Dan_Austin Posted December 9, 2011 Share Posted December 9, 2011 (edited) I don't have access to a machine shop, so I thought I'd try for cheap and simple. I'm fairly pleased with the results. Materials (about $45) (2) 20" 1/4-28 all-thread (4) 1/4-28 nuts and washers (4 nylock nuts to be installed after final tweaks) (4) 4" 3/8 OD .49 wall T6061 aluminum tube (4) 3.75" 3/8 OD .49 wall T6061 aluminum tube (4) 3.55" 3/8 OD .49 wall T6061 aluminum tube (2) 4" x 3/4" x 1/8" mild steel bar (1) 6" x 3/4" x 1/8" mild steel bar The coils are spaced apart with the tube using the pattern 4" - 3.75" - 3.55" - 3.75" - 4" The end brackets were fairly simple, a 90 degree bend 1" from one end, then a 90 degree twist about 1.5" from the other end. I twisted the brackets in opposite directions and mounted them such that the brackets would pull against each other. I then drilled 1/4" holes 1/2" from both ends. The short ends had their corners rounded off using a bench grinder to fit in the valve cover hold down pocket. (sorry I did not get a good picture of these) The upper middle bracket was eyeballed, and has loop on one end formed with a vise and pliers, and a 15 degree or so bend 1" from the other end to provide a slight lift to the outside aluminum rail. About 90 minutes worth of puttering to make and adjust the brackets. Once the coil rails were tightened the whole structure became very stiff, and trying to twist or flex the setup just moves the whole motor. I still need to trim the all-thread and replace the standard nuts with some nylock nuts. Edited December 9, 2011 by Dan_Austin Quote Link to comment Share on other sites More sharing options...
Tennesseejed Posted December 10, 2011 Share Posted December 10, 2011 Dan, that gets two very big thumbs up from me. Are you going to sequential with MS3X or using EDIS? Quote Link to comment Share on other sites More sharing options...
Dan_Austin Posted December 12, 2011 Author Share Posted December 12, 2011 I was planning to use a Microsquirt with EDIS, but found the trigger wheel options disappointing. Then DIYAutotune announced the 280ZXT CAS wheel, so I sold the EDIS gear I had. I will be going full sequential, and plan the install late in January or early February.

akeboshi Posted January 10, 2012 Share Posted January 10, 2012 What ecu are you running? megasquirt? How did you wire up the coils? Very cool, hope you dont mind if I use your idea. Quote Link to comment Share on other sites More sharing options...
Dan_Austin Posted January 10, 2012 Author Share Posted January 10, 2012 (edited) I was planning to use a microsquirt for the size and ready to go nature. While asking about the new V3 features I was offered a chance evaluate and provide feedback on the sequencer. So next month the rebuilt motor goes in and start the MS journey. Oh, and I saw a similar bracket using aluminum tube on a BMW forum, but the bar stock supports I can claim credit for, and the dimensions.

akeboshi Posted January 10, 2012 Share Posted January 10, 2012 So is the sequencer for microsquirt or for the V3 board? To my understanding the sequencer was to adding sequential to an ms2. I didnt think they were still doing the sequencer, its cool to know they are still doing development on it. Quote Link to comment Share on other sites More sharing options...
tech9 Posted January 23, 2012 Share Posted January 23, 2012 Awesome coils, I had a nightmare trying to do that with a CAS in MS2, i scrapped it and swapping to MS3 and I hope I have less issues with noise! Quote Link to comment Share on other sites More sharing options...
