emeraldlion Posted August 17, 2010 Share Posted August 17, 2010 I searched a couple of phrases without too much luck so I was hoping someone might be able to help. I'm looking for someone that has used the JTR 280zx trans crossmember setup in an s30 instead of the flatbar. Don't get me wrong I'm not knocking the flatbar as I know many use it with great success. I just saw the in tunnel 3 piece zx crossmember and thought I would prefer it if it isn't too much trouble to utilize it instead. Thanks for the help.

sticky280zx Posted August 18, 2010 Share Posted August 18, 2010 You mean like this one that is sitting at my house? Quote Link to comment Share on other sites More sharing options...
emeraldlion Posted August 18, 2010 Author Share Posted August 18, 2010 Not exactly. The bottom two pics are the s30 crossmember. The 280zx is actually a 3 piece with 2 pieces that bolt inside the tunnel and a third bar that bridges the others. Quote Link to comment Share on other sites More sharing options...

kamikaZeS30 Posted August 21, 2010 Share Posted August 21, 2010 Is it like a triangular looking piece? Where there are two plates that come down the trans-tunnel walls, then there's a bar across the middle that the transmission rests on? I think I have the mount you're talking about, in that case. I think it's part of the Hooker Scarab kit. Quote Link to comment Share on other sites More sharing options...
emeraldlion Posted August 21, 2010 Author Share Posted August 21, 2010 exactly like that. thanks Quote Link to comment Share on other sites More sharing options...
kamikaZeS30 Posted August 25, 2010 Share Posted August 25, 2010 Word of warning: I tried fitting that cross-member in my series one S30 this last Monday (two days ago) and it didn't work. I'm going to have to order or make something similar to the JTR cross-member. Quote Link to comment Share on other sites More sharing options...
emeraldlion Posted August 25, 2010 Author Share Posted August 25, 2010 What about it didn't work? Quote Link to comment Share on other sites More sharing options...
kamikaZeS30 Posted August 29, 2010 Share Posted August 29, 2010 (edited) The angles of the plates were wrong(they didn't spread far enough to touch the walls) and the cross-bar was about 1/2" to 5/8" too narrow to bridge the gap. That mount is designed to fit very snugly against the walls of the transmission tunnel-- and there's no way that was happening in mine. I took some measurements at key points along the frame and used a laser-level to see if there was something up with my uni-body, nothing seemed terribly out of tolerance (which is amazing for a 40-year-old Z). It may have been just poor manufacturing precision (i.e. there was little QA or the jigs are just worn/tired/old) or a fluke, but I think the JTR mount set-up, or something similar is probably the best solution. I like the set-up PParaska did, where he used the transmission cross-member to tie the extended frame-rails together. IIRC, it's very similar to the JTR solution but with extra length to extend to the rails on either side.

emeraldlion Posted August 29, 2010 Author Share Posted August 29, 2010 Oh well so much for that. Thanks for the input there. Quote Link to comment Share on other sites More sharing options...
kamikaZeS30 Posted August 31, 2010 Share Posted August 31, 2010 No problem, sorry it didn't work out. Any particular reason you were looking for that mount? You could make one just like it, with the proper dimensions and angles, probably wouldn't be that much more difficult than the JTR one.
