Yes some more info for the snorkel it looks very fitted with our feroza

landrover

[dai-hard]

Dont know if AIRFLOW are stiil around

Think when was looking at there product list rocky/feroza was the same part# as a landrover discovery series 2.

[MightyMouse]

Thanks - that's well worth a follow up.

[Goatse.AJ]

I'm gunna be investigating a custom snork very soon. The workshop I got to use last week is also an exhaust specialist, so I reckon I can get a decent snork for a very good price. Will keep you posted.

[tna racing]

i could make you one aj

[cj]

Yes, Airflow is still around. I just dropped my Vit off there last night to have their new 2.0 Vit snorkel (they've been using my Vit to develop it) fitted and will be picking it up on Thursday night. MM, if you want me to ask or pick anything up for you let me know and I'll see what I can do.

[MightyMouse]

cj - PM sent on our home board,but the answers yes.

It took me ages to find my post cos I didnt make its own thread, but I found that feroza again today.
Its for sale.. wide-track, 170000k's, bullbar, snorkel, tinted $7500

Took some more pics, but more importantly found the serial number on the bullbar.
Being an ARB bar they should be able to look up the serial number and tell u what car its off.
Numbers are as follows...
7873
888
344030

I will ring ARB as soon as I can, but if someone else can look em up that'd be great too.

Hellow MM. I hope you don't mind my ressurecting this post. I've working weld-filled side gears in front now and pretty happy with it. You said yours has a 4.3 tranfer gearing. I'd appreciate knowing how you went about the process of getting your transfer re-geared.

Thanks.

Hi Tansy.... "out of the shadows" at last....

Ok heres the situation as I see it ( and its my opinion, nothing more )

Diff Locks :

Rear - you can get from K&S Tuning in Germany ( about $2700 AU )
Front - nothing at the moment but am working on it.....

The "interesting" thing is that as soon as people find out how much they cost - the interest dries up. I'm currently working on a new locking front, but have not had a single "i'm interested" because it costs real money.

I'm not after any money from people, I'm not selling them - I will do my own regardless of others interest but........

Even mass produced lockers for popular brands are around $1800 all up and fitted - what do people expect for a minority vehicle like a hatsu ? This type of mod is expensive for anything, but for a vehicle that cost a few thousand dollars and has a whole range of issues needing rectifying before its a serious 4x4 it just seems people arn't willing to spend more on the lockers than the car cost.

Gears

Yep there's nothing available, but its the same story here, ages ago I asked if anyone had a busted transfer to get a set of stock gears out of to see what could be done. Not a reply.

It would be the same story on cost - expensive, but as with lockers, they arn't cheap for any vehicle.



So I don't really see it as a can't get issue, it more a matter of people won't spend the $$ to get what they say they want on a Feroza / Rocky.
IMO even if lockers / gears were available at around the same price as say Suzuki bits - I'll bet they still wouldn't sell. The "modify" culture just isn't there with Daihatsu's.


P.S. I have an airlocked rear, 4.3 Transfer Gears, Auto, lifted, widened and about double the suspension travel of stock. None of it easy - but possible.

[MightyMouse]

Its easy

Feroza Automatic bellhousing and torque converter mated to a Vitara ( AW4 ) auto and transfer case fitted with trail tough 4.3 gears. Zook driveshafts.

Engine moved, new transmission crossmember, new exhaust, some tunnel cutting etc etc etc....... Its a real "work of art" getting it all to fit as the AW4 is a big / long gearbox but really strong.

So basically there's no Feroza transmission components left.

[andoy]

Ooops, thanks mate. Afraid I'm not ready right now to tackel such a daunting project as yours. I'm trying to get a spare transmission with the intent of opening the transfer case to see gearing possibilities as you had thought of one time. Wish me well again.

You can only reduce the LOW gearing on the transfer case because you dont have any space to reduce the gearing for the HIGH gearing. This month we searched a lot of mechanics and sayed that only the low gearing of the Feroza transfer can be done. Now we are looking for samurai transfer or Hilux transfer.

[MightyMouse]

Most people want only the low gear ratio done - so a gearset would help 99.9% of off road Feroza's.

AJFeroza has my old transmission so he might be persuaded to part with bits of it so you can have a look / modify - PM him if interested.

Ferozamaniac - if you can't get a transfer close to home, I can almost certainly source one in Australia, but transport costs might be scary.

Greetings Ferozamaniac. Slower gearing in LOW is exactly what I'm after. Would you know/share how this is done in the Feroza?

Since you're looking for a Samurai or Hi-lux transfer case, would you know if they'd bolt on to the Feroza transmission?

Thanks.

[MightyMouse]

No they don't bolt on. From what I've seen the Feroza transfer is removed, an adapter / gearbox rear plate is made to hold a short jackshaft and another divorced transfer case is fitted, in this case Sierra.

The trouble is that you still have a Feroza manual box - hardly a strong unit under any circumstances. Some find this attractive as it increases the high range ratio as well ( +20% ) so the engine revs 20% harder at highway speeds.

I don't like the +20% high range gearing option - I'd rather keep the revs down and add some more power but I can see why some like it.

Someone of this board has done one, but can't remember who just now.

[ferozamaniac]

Yes mightymouse is correct you will need a custom adapter to fit the Hilux transfer. Sorry but since we could only change the Low gearing we didn't ask any more info how this can be done because we also wanted to change the gearing for the 2H also.

[Tzi]

20% higher on the highway wouldnt be such a bad option, considering the gearing loss from running bigger tyres.
Personally I'd LOVE to have lower gearing on my Low range.. crawling so so much LESS damaging to your car than the current speeds I have to use even in Low1st.
There is/was a gearbox AND transfer case on ebay last time I looked.

[Percy]

You can use a baby lobster transfer case (1lt Sierra transfer you want 83 onwards but) Give you 2.6 in 4l and 1.6 in 2H, should return the gearing to roughly stock with 31s or 32's possibly. Havent looked at how easy will be to fit Bosorovich has done a rock lobster and he said its a fairly easy mod to do, but the rock lobster (culmination of the 1lt and 1.3lt transfer) will change 2H gearing to much and will loose on road speed. I am going to investigate the possibility of the baby rock lobster over the next week will keep you updated.

[Tzi]

...should return the gearing to roughly stock with 31s

Is that 'roughly stock' in high, or in high and low? Would be awesome to have stock gearing in high range, but crawler gears in Low range...

[Percy]

Low gear with lobster case will be 2.6 compared with 1.7 in 4L, 2H will be 1.6 compared with 1.0, so high revving to get to 100 may occur. The low gears should be adequete to turn 33's easily (or thats what I'm hoping). Not entirely sure how it will work out but I need something to occupy my time. Now time to track a T case down.

[ferozamaniac]

With Bigger tires you will need lower crawling on 2H but nobody says its not worth to use shorter crawling when you use 4H and 4L. I will ask again how can this work out only for the 4H and 4L gearing.

[MightyMouse]

I'm not absolutely certain I understand what your asking but here's what I think you want.

A Suzuki Sierra transfer is NOT 1:1 ratio in any high range ( 2wd or 4wd ). This cannot be eliminated as it is a function of the transfer cases design. The exact change is dependent on the transfer gears fitted but AFAIK the taller the low range gears fitted the more high range reduction you get - like it or not.

This high range reduction can be useful if running bigger tyres, but you need to calculate the ratios / tyre size / engine RPM carefully to ensure the high range gearing is correct.

Other types of transfer cases do not have a step down in High range ( Suzuki Vitara ) when crawler gears are fitted ONLY low range is effected. Once again careful calculation is required to ensure changes in wheels do not lead to too low an engine rpm for highway driving.

With a small engine getting it right is very important, mistakes can lead to major problems. Its also a little more of an issue with a Feroza as there aren't the diff ratios available that a Sierra has so there are less options to choose from.

The good thing about the Feroza is that the 5.285:1 diff ratio is higher than most and its better IMO to have the torque multiplication occur in the differential rather than in the driveline - as long as you don't start breaking axles/cv's of course.
