Isuzu exhaust routing

[dobbo]

After the incident last week I have taken the sidestep of for repair, the sill had to be removed at the same time. It gave an image of how low the exhaust sits on a NA suzi
11824

Surely they could have routed it a bit better than this

[isuzurover]

Mine now runs on the other side of the chassis rail (after turbo install).

The exhaust is now tucked out of the way, and it gives me room for a fuel or water tank where the exhaust was.

that's basically where mine is; and it allows for the sill tank on the driver side and a fwt behind the transmission brake.... the location hasn't been any problem (clearance wise) and it does allow for easy access for mount/pipe maintenance plus it is out of the way of everything else

btw, they look good w/o sills don't they :)

I'm hoping to do the same on mine, but the space looks a bit tight with an LT95. Anyone fit a 3inch exhaust between the firewall and LT95's bellhousing? Apologies for the highjack.

mine is similar to Dobbo's... got pics of your variant?

How does it get past the firewall and inside the chassis rail?
Where does it exit?

I'm planning ahead and thinking about exit through the rear cross member or out the rear quarter like the UK challenge vehicles you see in the mags...

No apology needed, Andrew e has a solution to that, Personally I wouldn't mind crush tubes brasing and fish plates on the pass side outriggers and a 3inch pipe going straight through the holes.

[JDNSW]

Mine is the same as Dobbo's. Leaves a nice big open space behind the transmission - filled with a 60l fuel tank! 40l water tank on the driver's side.

I like where it is, and have never had any problems with it - although I have knocked a hole in the bottom of the water tank a couple of times.

[Bigbjorn]

Never a mark on mine and it is original. 430,000 k's.

If you have the sump that doesn't stick out towards the chassis rail, then there is enough room to run a 3" exhaust inside the chassis. It helps if you have a turbo because the dump pipe is further to the front allowing the exhaust pipe to go straight down between the engine mount and starter. There is enough space to then run the pipe over the crossmember between the gearbox and firewall.

Here is the only pic I have of mine:

Unlike Murray, I have the landie sump (which means an extra litre of oil capacity - apparently needed for steep hills offroad). So the dump pipe does a sharp turn then runs above the starter, then diagonally down past the bellhousing. Just after the bellhousing is a flex joint.

The exhaust (all 3" mandrel) then follows the chassis rail, and passes back to the other side over the top of the chassis rail where it dips down at the rear.

No chance of threading mine between the tranny and the chassy as I have a PTO winch. These exhausts also get fairly warm, I don't mind mine sitting a little further out under the siderail, in the airflow.

Yep same problem with ours the PTO shafts will be going in that route:(

That reminds me I still need to wrap some heat tape around mine!!!

What size exhaust is yours? When my exhaust bloke looked at mine, he reckoned there was no way to run a 3" exhaust out where the factory one goes (and still have room for 33's).

[1103.9TDI]

I've also got a three inch mandrel bent exhaust, which fits nice and tight (no muffler) in the standard position, but I'm not looking for any extra room to fit 33's.

[rar110]

mine has the original motor with garrett turbo. My exhaust follows the same path as Murray's by the sounds. Straight down between the starter and engine mount.

?'more detail??:)

The perenties run the wingless sump, the 4BD1 (4x4 perentie) I have in my RR has the wingless sump and I just bought a wingless sump from GWD enterprises for this last thing I acquired, as the sump has the wing cut off to clear the PTO shaft and exhaust, albeit, terribly done:D

That is the first I have heard that the perenties don't have the sump extension??? You sure?

The extended sump holds 8.5L. AFAIR, the truck version only holds 7.5L?

I have heard from a few sources that the extra capacity was to ensure no oil starvation on hills. However this would imply that the 4x4 NPR would also have extra capacity.

Thats what I wanna know about:eek:

I'm pretty sure, as mine is 4x4 perentie and I just sourced an army sump, no wing;)

So in theory I can re rout the exhaust to inbetween the chassis rails by just fitting a wingless sump?

Whats the price on one of them?

That's the one I bought, he has a few:)

[incisor]

he is just up the road from me...

he has N/A inlet and exhaust manifolds as well

There's also a cheap eBay retalier in the US for turbo exhaust manifolds ~ $160US with postage, comes with all gaskets and bolts. found a link to it on isuzurover's budget turbo install post.

Well Dave or Rar110 can confirm that???

I saw an NPR 4x4 the other day, but it was driving, so couldn't stick my head under to look ;)

He's willing to haggle on price too;);)

3" Exhaust next to wingless sump, and over crossmember.

Starter motor goes out through the top?. Just as well those four speeds (LT95) and the clutch plates are almost bullet proof!!!, might be a tad more complex replacing either with the exhaust in that position. Nice neat looking job, though, I really need to win Lotto, and have some LR therapy......anyone got next weeks numbers???.:)

Actually the thing I was thinking about was the clutch slave cylinder, not only getting it off, but how it would like the heater next to it. They are sufficiently reliable that I carry one .....

Mine is very similar to Murray's, Its a piece of cake to wizz of for gearbag/clutch access, I have a flange midway, about sump flange level aswell, so I can drop it there, without removing the dump pipe, so its a matter of minutes and no exhaust, not difficult what so ever

I had concerns about the slave, I was going to make a shield and heat wrap the exhaust, but its done 11,oookm now and hasn't been an issue, considering I spent last night out and found a few muddy hills, It sustained around 3 minutes a hit on the engine governor and if that hasn't killed it, it seems it will live on.............and if it fails out the way, its very easy to clutchless change an LT95, just begin with the box in first, Tx in Neutral at idle and slip it into low range and change up from there:D

I made the exhaust in a way that I can easily unbolt sections of it to get to things. Believe it or not, as close as the starter is to the header pipe in the pic below, it can easily be removed without moving the pipe. The slave cylinder is a bit of a pain to get to, but I can.
JD, you just reminded me that I've been meaning to wrap the exhaust next to the slave to protect it a bit from the heat.

Cheers, Murray
