RB240zDET Posted January 15, 2012 Share Posted January 15, 2012 Has anyone tubed their front end on their Datsun? I am considering this on my track 280z. I am wondering what all you removed from the front end and replaced with tubing. I am thinking cutting right in front of the shock tower down to the frame rail and stripping all the metal forward off. As I am going to use hood pin/latches to secure the hood I wont need any of the wheel well area for the stock hood hinges. I also am thinking of retaining the lower core support although I could remove that and weld in a straight rectangular bar to tie the left and right side frame rail into each other.

redneck1545 Posted January 15, 2012 Share Posted January 15, 2012 Following a front end accident 74_5.0L_Z tubed the entire front end. Firewall forward, all tube. Check out his gallery and you will be able to see what he did. Quote Link to comment Share on other sites More sharing options...
RB240zDET Posted January 15, 2012 Author Share Posted January 15, 2012 Thank you!!! Exactly what I was looking for. Exactly what I am wanting to do as well... Quote Link to comment Share on other sites More sharing options...
redneck1545 Posted January 16, 2012 Share Posted January 16, 2012 Not a problem. He outlined alot of the measurements and tube sizes in his pics too so that should make things alot easier for ya. Quote Link to comment Share on other sites More sharing options...
RB240zDET Posted January 16, 2012 Author Share Posted January 16, 2012 Well i am going to take that upper bar and take it through my firewall and tie it into my roll cage. But the rest should be about the same. Quote Link to comment Share on other sites More sharing options...
redneck1545 Posted January 16, 2012 Share Posted January 16, 2012 I pretty much copied his cage design with a few changes to the rear mounts behind the main hoop. I plan to add a low front hoop under the dash at some point and then penetrate through the firewall to the strut towers and such up front. I didn't want to add a halo or a-pillar bars as mine is a street car. He has a pretty rock solid tubed front end IMHO and it would be a good basis to modify to fit your own needs. I won't be tubing, unless I suffer from a similar accident as he did Quote Link to comment Share on other sites More sharing options...
RB240zDET Posted January 16, 2012 Author Share Posted January 16, 2012 I am copying his same design. I just can't tell in his pictures if he went through the firewall and I might as well go through and tie it into my roll cage. I should start this project this week and should have it done before the weekend. Quote Link to comment Share on other sites More sharing options...
redneck1545 Posted January 16, 2012 Share Posted January 16, 2012 LOL your fabrication skills are far better than mine if you can throw something like that together in a week. He did go through the firewall but he had a horizontal bar running just up under the top of the firewall and two vertical bars in each of the corners. He tied his door bars into this. My only suggestion would be to run a continuous front hoop with bends at the corners instead of running the vertical bars to a horizontal bar like he did. He has his front "hoop" in the engine compartment. Most of the others on here run theres inside the passenger compartment. I can see the justification for placing the hoop in the engine bay with a tube front end though. Shorter bars to tie into the tubed front end pieces means less leverage and stress on the joints. Maybe someone with alot more knowledge than I can chime in. Its kinda hard to see in his pics but take another look at the front frame connection photos where it lists all the sizes and you'll see what im talking about.

redneck1545 Posted January 16, 2012 Share Posted January 16, 2012 Here's my roll bar I did a while back, I took all of 74_5.0_l's measurements on the main hoop except I used 1.5" .095 wall DOM tubing for it. I changed the location of the rear stays for a cleaner look IMHO. http://forums.hybridz.org/index.php/topic/101790-roll-cage/ Quote Link to comment Share on other sites More sharing options...
