I'm partial to the closed boxes, that way heat doesn't transfer back into the engine through the air filter.
All preference really.
This has been debated to death. Some guy on one of the diesel forums put a sensor in his intake and tried with a boxed style and an open element. The temps were virtually the same with both styles at cruising speed since all the warm air gets flushed out anyway. Sitting at an idle the open element was a little warmer, who really cares at idle though?
I think as long as the engine has proper flow of air in the engine bay the temps will be down a good amount to use an "open box style"
Closed boxes are a pain in the ass to get to the filter but look a lot "cleaner" when you open the hood insted of having a dirty filter staring you in the face. Personal preference.
Did a good amount of work today on the trucks. Pictures will be posted momentarily. Body and box are ready to come off frame!
*edit*
UPDATEEE.
Dodge np205 I picked up for 300 bucks.
Seats mocked up, need to fab a seat mount for them!
My dog supervising everything, accidently woke her up from a nap....As you can see, mad face.
Long time no post! Project has been fairly slow lately because of extended hours at work. however...I have made up a seat bracket mount blueprint for the seats. Picked up a set of 275/70r16 BST Dueller revo2 tires that were scrapped off a guys truck for free! Going to do a tire swap sometime this weekend too. Atleast they will be more road worthy and will pass safety!
After a week and a half...just went apeshit on the truck. Cab is off the yellow truck. Engine, trans and t-case are out aswell. Hood, fenders and grille is off the blue truck, swapped to the yellow doors and rear window. Found a 97 Cummins with 320xxx k on it, bought a rebuild kit this pay. Going to take the engine in and get it swapped over to new parts..ported and polished aswell.
Need a trans, a buddy of mine that parts out this truck has a friend that has my trans I'm looking for..so I will hopefully be either doing a sell or doing a "swap truck for trans"
Pics are before the engine removal. Was getting dark by that point. Also have on order, a bunch of shit from LMC...Should be here in two or so weeks.
as far as the oil filter goes, i would go K&N. Ive run that in all my/my parents cars (im 17, so I may not be to acurate on some things I say) What kinda makes it great is the bolt head on the bottom, and i have yet to hear anything bad on them.
And my 2 cents on your lift- I know on those trucks, you can clear 37;s with a 4 inch lift. And honestly, if you were going through the effort of putting a cummins in, why not just 4 link it? even if just in the rear.
Four links aren't really for the road.. not needed. Its not the matter of linking someting, its actaully hard
If you are thinking of lifting it 4i DO NOT buy a kit. Looking for a shackle flip, trust me the ride is much softer than running lift springs.
The most I've ever seen a shackle flip for is 3", I'd also be willing to bet his current leafs are pretty sagged. If he runs a 3" shackle and a couple extra leafs it should be perfect.
the leafs in this truck are done. they are pretty well anti leafs and look concave lol. the back has 9 leafs in it.... Ill entertain the idea for a shackle flip and put some half ton springs in there with air-ride or something like that.
