While I agree with what you are saying about snorkels and water, following someone down a dusty road makes one with the cyclone type pre filter somewhat attractive.
Cyclone stops a lot of dust. I do it a little different, it's a Suzuki and I still favor using Suzuki parts... which means swapping in the induction system from a Hyabusa 1300 is legit. To add to the moto theme, I got Uni filters and oiled foam pre-filters for the individual throttle bodies. Clean 'em after you run 'em, it's rude to drive on the street with a dirty rig.
More work on the double transfer case mount today. I spent a pretarded amount of time assembling, mocking up, disassembling, grinding, fitting, assembling... I got the thing fitted, but it took me like nine attempts to get the clearances right. Behold:
I'm going to tack that reinforcing spine to the t-case bucket and see if i can still remove the t-case without splitting the cases to do it. I think I can, I think I can...
I've been sitting on these parts since 2007-8 ish. Samurai was my DD until my wife found 3rd gear when she was wound out and looking for 5th, so I waited until I had the space and enough shop set up to get going again.
Here's the gearbox train, together it's all one piece from engine to tailshaft like an old Massey tractor. Sidekick 5 speed with married 1.8:1 transfer case, front output chopped and welded, mated to samurai divorced transfer case, this one in 4.9:1 with a underdrive high range.
It is still a factory length drivetrain. The whole thing, engine, tranny, and both t-cases are under 400 lbs. That's why these little trucks work. Mine with a full cage, hydraulic steer, and full beef everything weighs 2700 lbs. If I went on a tiny bit of a diet, that makes my junk one ton lighter than a stock rubicon. That's how I get away with it. People use this engine in ultralight aircraft because of its weight. Motorcycle parts. Keep it light, use more gears than power, and it will never break.
