snorkeling an NAS 300Tdi

Has anyone found a good snorkel for a 300 Tdi that works on a converted NAS D90.
The clearance problem on the passenger side is the heater box and on the driver's side the brake system gets in the way.
I figure I could use the snorkel for the NAS D90 - V8, but I don't like how it runs across the top of the wing, covering the antenna, and hooks up to the wing vent.
Any ideas?

Clark

Clark - I've got the NAS v8 snorkel on mine, but if you get the proper intake plumbing from George at RDS then you should be able to install the 300 snorkel. George had the plumbing parts last time I was down there, but you'll have to cut a hole in your fender...

I recommend the over the wing type if you care more about function than form. The snorkels that come along the top of the wing are more protected from tight spaces and obstacle damage than the side types. that's what I have for my 2.8.

The southdown version works fine on the driver's side as well so long as you don't mind a little wing cutting.

Thanks everyone for the help.
I'll call George at RDS in the morning and google Southdown in the meantime.

Almost forgot....

Thanks David for the point about the side snorkels being vulnerable. Hadn't even though of that and I can put limb risers back on the D90 to protect the wing top mounted snorkel.

Couple images here:

The routing of the hose works really well but some are adverse to cutting as I said.

David,,,,,,,,,,,,,,

How did you route the hose inside the engine compartment? I've looked carefully at mine and it seems like the hose would crimp as you took it under the brake system and would then lay against the hose from the air-cleaner to the motor. Do you have any pictures that show your routing?

Not really but I can take some later this week. Hose is routed under the master cylinder and passes underneath the air cleaner to engine hose, on top of the trans tunnel. Use a high quality, high temp hose and it won't crimp in any way.

Called George at RDS today and he mentioned a problem with NAS 300 Tdi transplants: Water intake in heavy rain into the air cleaner unless you have a snorkel or the regular Tdi wing intake. The standard 300Tdi hose from the wing has a one way drain teeing off the hose midway to the aircleaner. This drains any water out before it gets to the aircleaner.
Unfortunately, I don't think the stock pieces will work because of the heater but it raised questions about DIY snorkel hoses - has anybody installed a one-way drain and if so what did you use.

There's one of those one-way drains in the bottom of carburetted 3.5 liter Range Rover air cleaner housings..

Mantec "over the fender" V8 snorkle works fine, does not require any additional parts or cutting and only requires that the stock 300 Tdi filter housing be rotated to bring the intake port above the motor and the supply to turbo hose.

Agree with Mark, and you will notice that the air filter canister is tilted so that the rubber valve is that the lowest point.
