I was wondering some opinions from people in the know please? I was told today by my local exhaust dealer that Bosch don't recommend u chip modern day diesel as the ecu will over compensate for.the chip and that a chip would.cause future gear box and drive-in damage... any thoughts mine is a non common rail 1kz thanks.Corey

Do a search plenty on here about chips. I have a 1kz with a Steinbauer and exhaust. Happy with the result. plenty of torque down low about the same at high way speeds.

Have u got better fuel economy? I avm looking for economy not as much extra power adding a scoop later

[PeterB Lurker Find all posts View Profile Close PeterB]

No I don't think my economy changed. 9.8 up to 11.6 highway loaded. Diesel auto.

I have just seen a local guy who is a diesel specialist and he is the second person to tell me not to do the chip as it stuffs the ecu up and not to go to big on an exhaust as it will mess with the egt. now I am baffled he fixes more modified diesel 4wd than normal as the can cause love of dramas with the ecu.

Now while I know jack shit about how they work (except what I have read, still not saying I understood it properly lol) but I know when I was looking at chipping and doing the exhaust on my 01 1KZ 90 Grande auto I had decided on the steinbourer chip, yes dearer then some others but have not heard of one person having a single issue with them so was the reason for my choice. I had done a lot of research on exhaust as well and decided I was going to save my $1000/$1500 on a beaudesert (spelling) exhaust and just get a straight through muffler/exhaust from the dump pipe back (no change of dump pipe not required). Now the head on mine cracked so after paying 4g for repairs I didnt have the $$ to do the mods and then sold the vehicle. As far as I'm aware (stand to be corrected) the steinbourer chip is put in AFTER the factory ecu so the toyota one will still alert to any codes/faults and keep the safety perimeters set ?? Steinbourer will also turn its self off at a certain point to stop any damage, I forget what it was but was a great idea and as far as I know the only chip to do it. Now I'm not starting any war here so please dont comment BUT for me personally there are a few issues with "chip it" chips for my liking. The back up service probably leaves the others for dead and he is extremely committed to his product BUT I for one don't want to be having any issues with starting, limp modes etc like others are having and I don't like issues as if things don't perform to the specs then I get pissed off really quicky and definately don't have the patience of alot of other guys on here who are willing to have a play, I like things to work 100% from day one, where as steinbourer I havn't heard of any issues, again this is just my opinion and not bagging chip it just what I have read and interpreted. I have driven a chipped up prado using steinbourer and definately made a big difference especially pulling power (compared to mine) but up top didnt seem to make alot of difference. Secondly the 1KZ is totally different set up to a D4D no comparison, drive both and you will know what i mean (actually don't because you will think the 1kz is the biggest slug box lol and will want a D4D). Except for the head issues on the 1kz's they are extremely reliable without injector issues and things like the D4D's. Personally I would add a chip of your choice, do the exhaust from the dump pipe back then drive it and enjoy. Steinbourer also have I think its a 30 day money back if your not happy. Some times you need to flick the power off and on I think to really see the difference, like anything after a while you get used to it then think gee'z its not making that much of a difference wasted my money then you turn it off for a bit then back on and you think holey shit it does make a difference, I'm sure others have thought this.........Cheers Steve

Hey steve was great to read your reply makes alot of sense but did u go bigger with the exhaust or just replace with a sports exhaust and why did u not replace the dump pipe???? I am looking for fuel economy getting the injectors reconditioned for under $500 then getting a bonnet scoop and chip and exhaust and maybe a long range tank want it for a tourer not a basher.

[Steve M Addicted PP Member Find all posts View Profile Close Steve M]

I didnt end up doing any mods as the funds dried out after the head went. I know of a couple of people who have just done the exhaust from the dump pipe back and are extremely happy with the performance. I asked a million questions about the dump pipe been fitted with a larger one, in general the response I got was by fitting say a beaudesert/typan (spelling) or the like I was just totally wasting my money. The supposed gain was 4kw, big deal, was not worth $1000+ when I could get the same performance just by adding a straight through exhaust for under $500. Not sure if you have looked at the genuine muffler but very restricted by mufflers internal baffles so by eliminating this factory muffler and fitting a free flowing one really helps with torque (pulling power) which would suit your outback touring needs. Bonnet scoop I think it a great idea. The idea of the bonnet on the 90 series is doubled skin and is designed to scoop air from just above the bonnet and feed upto the intercooler, I think a scoop would be the way to go most fit a hilux scoop but I wouldnt be cutting the middle support of the bonnet as this may cause it to shudder etc as speeds (you will see what I mean if you look up under the bonnet) There not an overly powerful motor BUT besides the head issue are extremely reliable although I was never that impressed with economy, was on par with my 90 series V6 I had prior. I get 11.6L per 100 out of my 120 V6 on a long run, I use to get 11.2L per 100 out of my 90 diesel ???? Certainly not real economical especially compared to the D4D's where they crack the 10's most of the time depending on mods and the right foot obviously. Long range tank ?? you should have 2 already dont you ??, one 90L and one 69L (reserve) You can replace the rear (main 90L) with a I think its a 130L Long ranger tanks but they do hang down a bit and for $1500+ may be a lot cheaper to carry that one extra jerry can if need be for that trip ??? decision you will make yourself. You need to update your profile, you dont say wether you have a 90 or a 120 other mods etc, just makes it easier to help you out eg my comment in regards to long range tank, maybe you have a 120 which has the two 90L's so would not see a need for any bigger tanks (although one is available for the rear of the 120 also). You may gain economy (though i reckon it would be minimal) I find the more grunt you have the more some times you like to use it by putting the boot down more which results in higher useage then before lol. I do this with the V6 some times, I drove a 90 V6 the other day and thought what a slug box compared to my 120 BUT again you get used to it. The 3.4L V6 are a fantastic motor and extremely reliable and have seen for myself some with over 400k on them and still going strong with out any major repairs. In standard for the 90 is a better vehicle straight from the factory with its better clearance then the 120 but with a lift the 120 is just as good. Another point with the 1KZ make sure you keep the cooling system mickey mouse and run genuine coolant to help keep the dreaded cracked head at bay, if your done around 180/200k plus then I doubt you will have any issues with the head now. Mine went at 103k and was serviced by the book plus more and wasnt neglected so luck of the draw, BUT the 120's dont seem to have the same problem apparently due to bigger cooling system then the 90 ?? only what I have read............Cheers Steve

Sorry, scoops air from just above radiator, just under the bonnet through the two black vents screwed to the bonnet (roughly where you would place your hands to lift the bonnet), but would certainly be picking heat up from the radiator increasing the air temp to the cooler. As your aware the cooler the air the better

This is a genuine dump pipe from beaudesert exhaust that has cracked at very low klms. Not sure if the problem has been resolved but this is the two pictures I sent to beaudesert asking as to wether they had rectified the problem or not as I was looking into their exhaust for my 1kz, I never did a reply back from them about my question. This is from some one here on PP but I wont mention their name.........Cheers Steve

For the 1KZ-TE, Steinbauer is definitely the way to go. In this market place, the performance module part of the industry, you pay for what you get. Link : http://www.steinbauer.cc/au/products...96kw__4uv/a3F/
I would install the exhaust system first as this will give you about 10% better performance and a little on the fuel. The main thing to remember about this particular engine is that the dump pipe area is very restrictive on the genuine unit. I like the Taipan XP brand 3" high flow exhaust system as for the dump pipe alone is a very good design being ceramic coated so it handles the heat coming off the turbo. Link : http://www.taipanxp.com.au/90Series-1kztePrado.html
This system will bring your EGTs right down as the flow of exhaust gases are well and truly improved. This gives the block, the turbo and associated components a longer life as the temperatures in that area are so much lower. The whole engine will run cooler and that is a good thing for this particular engine.
The Roo.

So would u do a 3 inch full exhaust including the dump pipe as well????

For what it's worth, I'd consider just fitting a straight through muffler. I found a significant reduction in turbo lag just doing this. I have fitted a chip, but removed it and returned it. I did not feel it added enough power to justify the expense.

Buy doing the muffler you a only spending a couple of hundred tops.

Just a thought.

To be honest, when I was installing all the heavy mods I was worried about turning the rig into a Chamberlin Tractor. The fact is I believe she still has enough poke to carry the load and still have enough on tap to be there when I need it. I priced up several different chips and came to the realisation that Ill only be looking at an exhaust upgrade at this stage if im looking for more torque. The money investment imo can be used for other practical mods, major maintenance and trips away. Everyone has different needs eg constant towing and hence hunt for more power, but im not building another performance V8 here. reading through all the previous 'chip' threads there are positives and negatives/ amazing fuel figures and terrible engine problems. Who knows, maby I might put one in if it came up at the right price later on down the track, all im saying is with all the current mods, the old rig is still a very capable/ responsive vehicle and you really have to look at why your putting each and every mod on your setup.

Cheers

Hi Whatever
Thought i would let you know about my experiences with exhaust mods and chips
I have an 06 auto with the 1kz and fitted a Manta 3inch exhaust and dump pipe about three years ago and was very happy with the results like more torque more responsive off the mark. Cant see the point of increasing the exhaust size but not the dump pipe as you will still have the restriction of the standard dump pipe. The turbo needs to get rid of the exhaust gases and heat more efficiently especially if you fit a chip and this cant be achieved without increasing the size of the dump pipe.
This change in the exhaust at the time achieved what i wanted out of the vehicle and decided not to fit a chip however when i got my camper trailer ,well thats a whole different story
My first trip was to Shark Bay and the Adventure Off Road Camper wich would have to weigh over 2 tonne all loaded up was definately a challenge for the old 1kz !!! ,any slight hill would have the auto kicking back -especially with the cruise on and forget about overtaking anything thats going 80 kmh or more
Decided to look into chips before my next trip and decided on a chip it chip which was cheaper than some of the others mentioned in this thread and also came with an EGT probe and controller
Just returned from a 5 week trip to the Kimberley and nearly 10 thousand km travelled with camper and have had no issues with the chip at all and it performed brilliantly !! way more torque and was overtaking triple road trains (safely ) no problems at all and holding top gear on most hills with cruise control on
So i guess it comes down to what you want out of your vehicle for me the chip has done wonders for towing but also around town it is way smoother and more responsive
From my experience i would do the exhaust first as well as dump pipe as if you decide to fit a chip you will not get the full potential of the chip as you cannot tune it to higher levels as the standard exhaust and dump pipe is too restrictive and cannot handle or get rid of the extra heat .Thats what i also like about the chip it module with the EGT controller as it returns the module to astandard tune if EGT gets too high then returns it to the higher tune when temps drop down again all automatically
Cheers

Thanks for your story I am in the same vote as u you have helped alot. I will be setting up for touring and towing so will do a 3 inch upgrade including the dump and full exhaust and a sports muffler. And I think I might go with a steinbuer chip as it is installed after the ecu so it won't cause any issues with the ecu. And then will be cutting a hole in the bonnet to fit a hi lux bonnet scoop to keep the intercoolea little cooler and installing a k n filter with a snorkel sock to keep as much dust out as I can will get a egt set up to keep an eye on things thanks

[Steve M Addicted PP Member Find all posts View Profile Close Steve M]

Hi there Whatever, just to let you know a test was done on all the filter elements and the best filter for keeping dust out was the genuine toyota filter !!! Choice is yours obviously but also be weary of filter oil on any sensors ?? Dont think the 1kz has any to worry about...Cheers Steve
