that triton is a different animal to your 4m40

it will be a common rail diesel with electronic diesel control, and vnt variable vane turbo... you dont stand a chance of tuning like he does without converting your 4m40 to electronic control and a variable turbo

Yea.....Mikka,you should not expect you had the same result as the 3.2 DiD....or if you want power you can directly swap it to a 2.5 DiD which is a 4D56 Commonrail Turbo Diesel Wink

I had see couple of MK1 Pajero converted to 1JZ-GTE engine,thier acceleration was evil  violent3

The VGT is not necessary as this is porvide more benefit when you are towing or runs on a constantly low engine speed but high engine load conditions,on Mikka condition,what he wants is power and as he does not tow something heavy frequently thus he does not need that and that VGT thing once goes wrong is very expensive thing Mad

acceptable level for me, but those cummins diesel dragster are too serious.

I've read some a Thailand forum and the forumer were talking about 4m40 engine, they said that engine can juice out a lot power, but they didn't talk about any mods...

Hey gents,

i am MonsterTriton,
the video clip and shed page is of my triton.
btw that burn out clip is very very old now:0 when i was still only making 255hp with auto gearbox. Smile

i actually have a new dyno clip-which is now old in this business:
our last dyno made 330hp and 727nm of torque
check on youtube,
monstertriton dyno.
and chevy colorado 361hp 2.5

for the links.

the triton has had some more serious work done to it now, are are planning to achieve close to 400hp and 900nm of torque.
defentially need to use a twin plate clutch Smile -im not using std gearbox anymore. im using the pajero bigbox 5speed manual.


our built 2.5l chevy colorado (same is isuzu dmax 2.5).-street use.

we sell many commonrail diesel parts, such as piggyback kits (increase 60-80hp and 130-150nm of torque easily on all types of 4cyl commonrail diesel engine)
with std turbocharger, intake and exhaust.

we do stage 1-3turbo kits, injectors, pumps, headers, intakes, brakes, suspensions, hybrid turbos, wastegates etc etc etc.

we supply to brazil/pakistan rally teams, circuit teams, drag teams and also street use.

feel free to contact me regarding any questions:

well, I've been away from home for a while and study at oversea. Now I'm back and done some simple mod. I've serviced the car and fit in a large radiator.
So far no upgrade parts yet. But I've done some tuning that austinsevenuk been suggest.
I turned the max fuel screw for "i'm not sure" how many degree, the idle jump from 800rpm to 2700rpm, and having some hard time getting idle back to normal Very Happy.
Adjust everything max at the boost compensator and also removed the restrictor at the bottom of the diagphram... well, no black smoke, just cloud that enough to blind people before the boost come.
The result, boost automatically rise from 0.9bar to 1.5bar(after 100km/h 3rd gear auto), cannot confirm, maybe higher after 140km/h
Because I'm using automatic gear, slingshot style launching from fully stop require Brake+Fuel and foot off brake, floor the fuel pedal. All I got is burn out until I left off the pedal Shocked , I didn't know it has totally no grip during burn out.

Because of the fan clutch, it some time gave me poor acceleration(but better than old setting)
And one downside, I have to manually shift during full throttle, because the gear will gone crazy sometime, I'm not sure why.

The power increased is a lot a lot after adjusting the boost compensator, and the engine ROOOAARR during full throttle Twisted Evil

I apologize to austinsevenuk about the increasing boost pressure argument. But I have to disagree with you that 4M40 don't have potential...
And some of the people here say that 1.3bar above will have knocking, I've to say NO, no burn smell, no knocking, no cracking sound. It sound like a muscle car engine and ROOOAARR all the way until it suck up all your fuel like mad!!

After I enjoy with the current setting, I'm going to turn the fuel screw up a little more. I'm going for 2.0 bar boost.... of course I've to do some more research before doing that.

Use pipe plug to replace the relief valve. But removing the relief valve require superman power, I suggest using light hammer tap on the wrench.

Omn my 95 nj 2.8tdi . I wound up the boost from 8-9 psi to 11/-12psi with a bleed valve. was going for 14psi except manifold pressure relief valve kept going off at approx 13psi.

I've heard of people swapping in the pressure relief valve from the earlier 2.5td motors due to being set to 20psi from factory? is this true?
Failing that anyone used a blanked off bung from a plumbling store? what size bung did you use?

Did you find an answer to your question?  I'm looking for pointers for my 94 Delica 2.8tdi...
