so far mate we have achieved a healthy 330-350hp for a daily driven Fortuner.
then again that has taken into consideration you have done the transmission modifications.
(which include, adding extra friction plate clutch, increasing the line pressure slightly, using some john deer hydrostatic fluid
and a external transmission cooler)---makes the std auto handle alot of torque and abuse.

if you are talking about the std transmission, transmission slip is highly prone after 275hp.


i need more information on your turbocharger...and also unichip is popular,
they still can not claim near the power the DMS units make's that i sell.
dms monster kit not controls the injection pulse width, and the commonrail pressure,
but further unlocks boost limit.

std engine can handle 3bar of turbo boost daily driven. nevertheless,
it all depends on the tuning, as if your producing heavy smoke, your egt's will be very high (above 800* c,
will melt your pistons etc). so aslong as you can maintain lower egt, turbo boost is not an issue.


realise on our drag pickups, they are running 60psi!!! 4bar on std internals. it all depends on the tune,
but ofcourse daily driven 4bar is not raliable.

besides that we have over sized pistons, More importantly Pump modification kit, and INJECTOR CAPS- big cc, etc etc.
how much turbo boost are you running? what sort of external wastegate are you running? or are you running std swing valve?


as for the intake k&N they are wronge sorry, you can fit the cone type filter.
as you can see from our trucks. you need to cut the original map sensor mount from the original box.
you have to utilize and maintain the std diameter of the map sensor and its mount. as long as you do that, you can design what ever intake
pipe you like and what ever filter you like.


If you want more info you can also mail me.
of course I sell all parts.

I don't know how to determine what is the best performance chip. On this board, the (German) Race Car performance chip seems to be working as advertise. Are there any downsides? In what way is your chip a better choice for the Isuzu 3.0 that I'm looking to buy in a few short weeks?

downside is izus auto box cant handle more power, at least according to izu. vgs is detuned when sold with auto.

That's interesting.

in the heat of LOS every auto should have increased oilcooling when tuned. even with a careful driver its a huge amount of tourque to handle for auto. espesially on fulltime 4x4 as no wheels slip on full throttle. 40k km auto oil change in LOS should be good enough, but make garage aware about extra oilcooler when changing, so they know from the start more oil is needed

on Vigo and Fortuner 3,0 auto, Toyota has solved this for me by installing one more original oilcooler at a few thousand baht

One of the advantages of the Pajero is that it is 2WD with optional 4WD......

[transam]

Auto trans oil temperature is critical for survival. The biggest killer. Ideal temp is around 175 degs F. Go on forever. I have recorded 200,000 and 250,000 miles in two cars. In my drag car had no oil temp probs (manual shift Auto with temp gauge) cos of big external cooler, only breakages l had was with internal part failure and not heat related.

The Vigo has an auto trans oil temp warning light on the dash, but l haven't a clue what temp it is set at, which is great, if it comes on stop the car. A temp prob can destroy the friction plates in no time.

The Australian spec Pajero Sport (known as the Challenger over there) comes with a newer VGS (variable gate) turbo-charged version of the 2.5L engine, which produces 178HP/400Nm. However, the automatic versions are detuned to 350Nm - and that's using an [assumedly] more advanced 5-speed slushbox, rather than the older 4-speed version we get here in LOS...

There have been a number of posts on the topic of auto box strength here on TV before, with one diesel tuning vendor suggesting a change of Auto transmission fluid to beef the stock unit up.. Of course there's more in-depth mechanical upgrades possible too.

There's also an ongoing thread running on one of the Thai language Pajero Sport forums discussing problems with gear whine on the PJS, and apparently there will be an official fix from Mitsubishi coming around May this year. Who knows, perhaps that will help it handle more power too..

Bummer....(and to think, these chip mfg boast of the amount of documented performance my Isuzu auto would gain if I bought their chip!!)....so I take it that with this vehicle, you would suggest it would be best to leave well enough alone and not install any chip?

Adding an aftermarket transmission oil cooler would probably be the best thing I could do to help protect the engine's life?

Does this mean that the stock Isuzu auto has more hp/torque than the Vigo?

Not the engines life; the transmissions life. External trans oil cooler is a great idea. ditto an oil temp gauge.

2 wheel drive or 4X4?

[philipm]

both the isuzu/chevrolet and also the vigo, are all made by Asin.
all autos can handle in the high 200hp std, but ofcourse the autos-
are recommended to fit an aftermarket oil cooler, the std ones are built into the radiator-not a good source for cooling the atf.

as long as you change to the recommended if not better grade atf every 8,000km tranmission wont slip. if it does,
take a look at the atf color and thickness incase. it most like would be burnt and the atf will appear to not have much thickness to it.

Easy test, colour, on the stick should appear to be light pink and look transparent and smell (to me) sweet, even after lots of use.  If dark pink, red or hopefully not brown and/or smell burnt,  problem.  

On big horse power stuff l raced and used on the street with a (manual) auto box, l had a chrome dip stick where the oil looked clear, using Ford ATF. Although the trans was designed for GM use (not Ford) the Ford ATF was proven to handle the heat better. The trans was fitted with a deep sump for more oil capacity and a big external cooler and filter. The oil Temp gauge read 175-185 degs all the time, even when racing and that was with a 3,500 rpm stall converter that in itself created lots of heat.

So it's good practice to check your trans oil for these signs.

Imagine your smile with 25% more usable torque when you get behind a slow mover on twisty roads, that is the point of my thread. It really does make a difference.  

As phillipm says from his experiments, the box can handle 200+HP with no probs.

Hi trasam, I wasn't dissuading away from what you were saying. I've just never been in the situation here in Thailand, where my MU7 hasn't been up to the task. The extra ponies would be nice, but not right now, as it has plenty enough usable torque for me for the moment. When I plan to get my bike trailer built, I will more than likely buy the Power ECU when I have to travel. I've kept the website links.

Cool, but then you will have to think about trans oil cooling, even with your stock system.

......as a wise person once suggested, "....use Synthetic engine oil" (which I will do religiously), can I assume the same applies to the MU-7 at transmission oil changes? These transmissions also accept Synthetic fluid? 40,000 km is the recommended transmission oil change interval?

I must confess l have never looked into synthetic trans fluid. To be honest l didn't know they made it for auto trans. The Ford ATF always did the job but now you've mentioned it think l will do a bit of research.

......this fluid has been on the shelves in the states, Mobil One brand, etc. If it will work in the MU-7, I'll have bottles of it brought to LOS in the luggage of family and friends (as I am now doing with bottles of my favorite) 'Meguiars NXT Generation Tech Wax 2.0', and will use it in the trans for the life of the car.

As phillipm says from his experiments, the box can handle 200+HP with no probs.

hp is not the problem for auto. tourque at a wide rpm band is, like 420 Nm @1400-3400rpm. 450Nm at 2000rpm and 350Nm the rest af the band, like Nissan has done with navara, is more easy for auto to handle  

both toyota and izu have "recalled" autos to check overheating. my 2004 vigo was recalled after only 6 months, the quiet LOS way by a phone call saying they want to check my car. I find it likely mitsu, izu, chevy and vigo all use the same aisin auto, a dated 4 speed unit. but it seems Vigo has better stock auto cooling, and thats why izu must detune VGS. cheaper to detune than to install oilcooler

as a tuner, phillpm says they can handle more power, but he also recommends replacing auto oil every 8k km. I dont want any probs, I want 200k km from my auto and 400k km from my engine with just scheduled service, so I improve autocooling with extra oilcooler to handle increased heat from engine tuning

BTW, least expensive way to tune Vigo/Fortuner is to place icecubes on the intercooler. Colder air, more O2 in air, more power

I am with you in that 'I want 200k km from my auto and 400k km from my engine with just scheduled service' so I will most definitely be adding an aftermarket oil cooler and hope that this trans will take synthetic fluid.

Do you think the Isuzu MU-7 (auto) VGS engines come 'detuned' from the factory? Earlier in this thread, another poster had the opposite opinion.

Given the state of these transmissions, what percentage would you figure that the addition of an oil cooler would protect the trans from the extra power these engines get from performance chips?

I mentioned before, 2 cars 200,000 miles + on each, these cars were work horses, engine oil change every 3-5,000 miles, but for all those miles probably had the trans oil and filters changed "3" times, and ran perfect when l sold them on.

But, l would agree with the 40k trans oil change. Trans oil doesn't have the contaminants thrown in by an engine burning stuff, getting past the rings into the sump  etc. This shown by the colour of new oil after a few miles, dirty, but trans fluid in a normally operating trans hardly changes colour, nice clean sealed environment with an internal filter.

If temperature is managed correctly so the oil maintains it's viscosity, no problems. Also trans fluid has an operating temperature to be reached for perfect trans operation.

As for Isuzu not having a cooler to save cash, that's incredible, makes you wonder if there are any other "important" cost cutting stuff on the motor.

havent looked at the izu VGS spec for a couple of years, but when I last did, the VGS auto had lower tourque than manual, simply ECU detuned. I know a IZU importer in EU very well, half their sales are ambulances, and they are all moded with extra auto oil cooler to handle heat and avoid warranty claims.

I d say 210 hp and 420 Nm at 1400-3400 with extra oilcooler under truck or in front of every cooler, auto should be fine for 200k km. clean oil every 40k km, or towing 2-3 ton trailer, more frequent. thermostat on oilcooler is needed in EU, but not in the stable airtemp of LOS.

rebuilding an auto is not very expensive in LOS, but I just dont want the hazzle
