  1. 280z dash rebuild new idea

    It is very similar to the stock weight, maybe a few ounces heavier. When I pull the passenger side one I will get a weight difference. Before I finished filling everything in with foam, the screw that attaches it to the metal arm can be adjusted for more or less tention adjusting the amount of tension it takes to pull it down. I just set it where I liked it and filled over the screw with foam for a nice clean look.

    The caulk and paint are outdoor use so I am hopeful that won't happen. The foam I used was green insulation so it should be fine. I painted it with bed liner to give it a texture so it should be fine.
  3. 280z dash rebuild new idea

    This is to all you haters out there. In the hopes of improving the process I continued to search and attempt to improve my idea. After further investigation, I found that many people use foam for stage props and cover them with a type of material. this is called to as hard coating. there is many different types of coatings that you can buy or make. From my searching, the most common that I found was a mixture of latex paint, latex caulk, and joint compound. the paint thins the caulk and the joint compound hardens the surface. these three ingredients can be mixed in any different amount to achieve a soft pliable or rock hard surface. I decided that since the surfaces of the car should remain flexible I would not add any joint compound. I mixed about 2/3 caulk to 1/3 paint. I used the alex siliconized latex paint since it is still paintable and coated the foam 3 times with a paint brush letting it dry 24 hours between coats and sanding with 60 grit sand paper in between coats. Also, the paint that I I used was satin and I had it tented black to help make it easier to paint. when mixed with the white caulk it was a nice grey. My first impression was that it was still laying on very thick and that I should thin it out but though the drying, it leveled out some and then the sanding helped. The third coat I should have thinned out a little more to help it smooth out the surface but through sanding I was able to make it pretty near perfect... but I will let you be the judge of that... As for the test piece. I have always hated the soft trashy visors that came with the car. I tried to remove it and make a new one out of vinyl but it was no better. In the end I removed it and glued two pieces of foam over it. In between the two pieces of foam is a 1/4 piece of cheap hobby wood. This did two things; one, it filled in the area that was taken up by the wire frame, two it added more stability to the visor. After that I filled in the edges with great stuff spray foam and trimmed down to the wire frame with a dremel sanding drum. The actual shaping was done with a sanding block and 60 grit sand paper. this ensured a smooth and even surface. In the end I am very pleased with the results. In the future I will be buying another dash to redue, and more than likely start recovering or making my own interior panels with this method.
  4. Sorry. It's been a while. I do not have mine notched, I check them for torque every 10k miles or so and no problems. I also have poly bushing if that changes anything.
  5. I have 5/8" bolts in mine and have been drag racing it. No problems. I have also pulled them and checked after about 5k miles and they had no marks.
  6. Drag racing suspension

    Well I definitely plan on a dedicated set of drag slicks but I have to increase funds first. I have the set of street slicks, daily tires, and it is going to take some talking to the wife to get a 3rd set of tires. I don't have a goal for the car. Built it to be reliable and I love going fast. Obx lsd is in the future with a set of wolf creek racing axles and coil overs. Should be about 2k next time I have the money. I am also currently seperated from my car. I had to move up north for a while and couldn't drive the Z up and the truck. I should have her back around Christmas
  7. Drag racing suspension

    I have everything you just mentioned except the welded diff and the roll bar. I am running a street slick ment more for autocross so I know I am losing traction with them, but I was running the same times with my touring tires. I know I am putting down around 350-400. Definitely wish I had them slicks like that though.
  8. Drag racing suspension

    Check out this page, toward the bottom. They call it a subframe connector but it looks like it would do the same thing as a torque arm, lift weight off the nose and apply it to the rear for better traction. https://ls1tech.com/forums/cadillac-cts-v-2004-2007-gen-i/1549239-tuning-irs-drag-racing.html Also, I attached two pics of the same thing where they attach the subframe to the rear suspension. Don't know how much upward torque is applied though, I think this design more helps with wheel hop.
  9. LS376/480 4L70E HELP!!!

    Btw, the best way to do it, is to get the engine and suspension set up, get the car running, take it all back apart and then do the body and interior. That's my opinion anyway.
  10. LS376/480 4L70E HELP!!!

    -Kits: i did thd CX racing headers and engine mounts but I used the 4l60e transmission so the headers had to be modified and every welder that looked at it said it couldn't be done... so I bought my own, figured out how to weld SS and did my own turned out fantastic. I will later add duel cutouts before the Y pipe. If I had it to do over I would have gone JCI all the way. I would have also turboed but that's me. -Suspesnion: left mine mostly stock but I'm getting back into that now. I did the poly bushings and am going to do 4 corner coilovers, nothing special. This is my toy that likes to make the mustang and camaro guys wonder why they just spent 40k on a car when they just got beat by a car that cost 10k to build. Brakes: Silvermine for the 240 caliper and 300zx roter. Remove the stock prop valve (replace with a union) and you will be around 70/30 braking. Paint at 2k: get it running. Dynomat: get it running. 225 tires: same I got... can still spin them on a dry road while going 40. Driveline: jci makes a great steel shaft. No need for aluminum since it is so short the weight savings is going to be minimal. I think mine is only 2.5ish feet, maybe 7lbs. CAI: focus on getting it running. Radiator: stock 3 row and then go get a random hose from autozone that fits (go behind the counter and pick). Fuel cell: I swapped over a camaro tank and wish I had left the stock one with the walbro fuel pump. Quote Quote this
  11. Drag racing suspension

    So miatas use a open style torque tube that runs from the differential to the transmission. It is the same setup as the corvette torque tube except that it is only closed on 3 sides to make it easier to maintain. And it doesn't need as much since there isn't the torque of a v8 in there stock. From my understanding, the key to a hard launch is to be able to transfer vehicle weight to the rear wheels as fast as possible. 4 link push and pull the frame up applying all weight from torque to the wheels. The torque arm is mounted to the front of the differential and as the nose of the diff rotates up it pushes the front of the car up applying the weight to the rear. My thought is that even though it is an irs, the diff still acts the same. Under hard acceleration, the nose of the differential launches upward. This is the reason for the strap over the diff and the reason the rubber mount under the differential separates. That being said, if I was 100% sure this would work, I wouldn't be asking here. My design thought is to remove all the mounting on the front and then have 4 pieces of angle iron bolted to the nose going to a torque arm on both sides of the drive shaft. This will also make it easy to make a drive shaft cage.
  12. Texans, help me out.

    Last time the guy poped the hood and said "is that stock?". They do not care in Texas (this was in bell county as well).
  13. Drag racing suspension

    Btw, I have upgraded to poly bushings, springs and struts and do use the car for autocross as well.
  14. So I have finished my ls1 4l65e swap and love it. Anything over 3k rpm gets a little scary. Went to the strip to show up all the mustangs and running street tires got nowhere... literally spun tires for the first 60ft and then just rolled through the finish. After buying a set of street slicks I went back. Still could not launch as hard as I wanted to but I was running low 12s. My thought is coil overs, bigger sway bar, lsd differential and true slicks. Well I am getting ready to start my next build (63 c10) and am researching what I am doing for suspension and have decided to keep the solid axle and add a torque arm. After researching torque arms I thought why not put one on the datsun? Is there a large difference since it is a irs? My thought is the torque is still going through the nose of the diff (thus the clunk that I had to fix). My thought is remove the extra mount over the diff that I added and remove the stock nose mount and replace it with a bar that goes up to my transmission mount. This would make it to where the diff is mounted on the rear and then to the front of the car right under the driver seat.
  15. You make a good point. I still think it is a viable option, just not for what I need. I guess I'm going to chop everything up and go with coil overs.
