Delica JB500 Camper

How do you re torsion the bar?

Has the installation steps, but...

To re-index your torsion bars...
  1. Measure the height of your Delica from the ground to the bottom of the front wheel arch (BOTH SIDES)
  2. Jack the front of the vehicle up and using jack stands support the FRAME without putting pressure on the wheels/suspension
  3. Loosen/Unbolt the torsion bar tensioners (as shown in the above post)
  4. Turn the tensioner (DOWN) 2-3 notches (depending on how high you need) and then re-tighten
  5. Lower the front of the vehicle and re measure
  6. Repeat until perfection is achieved.

So turn the right side torsion bar clockwise and the left side anti-clockwise is that correct? I assume the more you go up the harder the ride becomes is that correct? thx

From the adjuster end, yes.

Not really, they are constant rate springs... the bigger issue is running out of suspension travel/topping out over bumps.

I am not looking to lift too high my current tires are 195/80/R15 about 27 inch tall, I will probably go is 30 inches tall max. On the rear from what I understand reading the threads some adds leaf spring and some replaces the shackle, since I am not lifting too high I am thinking adding a lift spring will do. I also want to add an air bag in the rear. Recommendation for lift spring and air bag is appreciated it will save me a lot of googling time. thx
 
My engine's waste gate opens at about 11 to12 psi boost and at egt temp of about 1200 degree F. How do I increase boost and keep the temp between 950 to about 1000 F. I would to get to about 13 to 14 psi boost and keep the EGT to 900 to 1000 degree F.

The engine is comfortable at 10 psi boost and about 900 to 1000 degree f. cruising at 55 MPH. thx

The boost pressure and EGT are not directly interconnected... you can increase the boost pressure in the hopes of making more power, or in the hopes of providing additional airflow to keep the EGTs down, by shortening the wastegate actuator rod. If you go to/above 12psi you will likely have to remove the over-pressure dump valve on the intake manifold and block the opening with a 1" steel pipe plug... otherwise it will open and you will get no boost.

At a certain point the throttle peddle becomes the EGT controller more than anything else... regardless of what boost pressure is being made.

Ok thanks I will work up enough guts to do this I am also reading up on this thread https://delicaforum.com/index.php?threads/tutorial-tuning-the-4d56-for-more-power.707/ I will probably do the larger down pipe first and maybe an intercooler. Do you know where I can get a bolt of prefabricated downpipes? thx

I re indexed my torsion bar two tooth my JB500 lifted from 14.5 to 18.5 inches, that is a 4" lift!. Is there anything else I should do to support the torsion bar? that is a lot of weight for the torsion bars to carry. I am taking it to Atlas Spring suspension to add lift spring to the rear to level it.

I will also replace the shock absorbers, do you have suggestion for a shock absorbers.

My current tires are about 27.7" tall I am thinking to going to 29 or 30" tall, would appreciate you though on this also. thx

Thank all for your help.frontlifted.jpeg
 
This is more uncertain as the JB500 isn't really the same as the unibody L300... On the L-300 the suspension height should be ~ 22" from center of the hub to the body line (top of bumper). When it is correct, 30" tires fit just fine.
I have no idea about shocks for the JB500... they could be the same, or entirely different.
 
here is an update on the lift, added 3 springs from atlas suspension, bilstein shocks, shuckels from rising sun, 235/75r15 29" tires I could have gone to 30". lifted 4". thank you all for your help. more update to come.

damn look at that leaf pack! did they re-arch the main at all or just add those 3 to the pack?

they re-arch and added 3 springs, the shackles also did a great job on the lift, it is 1" higher in the back, design so that it does not sag when I am carrying up to 500 pound on my hitch carrier. I have driven it over 1000 miles with the hitch carrier I am very happy with the performance. Tomm I am adding a 1.5" wheel adapter to widen the rear and maybe the front.thx

We need the before and after stance shot.
Go grab a beer, head outside, pull that spacer off, take a shot, then reinstall ;)

And that thing is massive!!!
That would take too many beer. Wish I took those pictures. Pictures below is best I can do.9F5D1F22-706C-4D61-9435-C5B650EE5EED.jpeg20758CF7-F380-4FAE-9C90-A384C62E79AB.jpeg Rear is 3.5” and front is 1.5” The JD500 need a wider track wide.
