What to expect?

[Robv]

I just bought my first mitsu: a 1990 2.5td pajero and all though I've been told that these aren't the speediest of vehicles out there I really don't have anything to reference off of.

I wanted to know what speed and rpms you guys are running going up hwy 1 cut in north van.

Also I wanted to know if the famous delica tune also means adjusting/turning the diaphragm located on top of the IP? I ask because the previous owner had the tune done 2 years ago and the diaphragm was turned with the "0" facing towards the pass side headlight.

One last thing
After seeing the diaphragm I decided to shim the waste gate up by 3mm in hopes of getting the "mad crazy omg wtf!" power boost that others have said online. Although I did get a bit more pep out of it, I hardly noticed it and was honestly expecting way more out of it. Is this normal ? Let me know !

Expect to blow it up if you do not add a EGT Exhaust Gas Temperature gauge before pushing the 2.5L...

timing belt, tensioners, and cooling system serviced?

[Robv]

Thanks for the heads up

And yes, deli tune done two years ago , all new belts last year and I changed all the fluids and filters as well as flushed the coolant system at a local shop when I bought it.

On my L300 the biggest bump in power came from a new ip pump. It was a literal whoa... What the ell... I had played with the turbo, 2.5" exhaust and some other things. Nothing compared to the ip pump. Mine was a 1990 L300

Another owner here in Saskatchewan just had hers done and she said the van never went that fast /pickup since she's had it. She just had hers done in the last 2 weeks.

Good to hear that! I should be getting mine done in a few weeks..

Brand new IP, or serviced with new seals?

Just had mine serviced, should get it back today.

i have no other delica or pajero to reference off of so that is why I'm asking "what to expect" before deciding to throw a good amount of money at it.

I would like real world findings to see that maybe i was expecting a bit too much out of it or if indeed it needs service. this is why i ask what speeds and rpms you guys are running going up the cut.

I can't get through to CVI, so i ask here if the deli tune includes adjusting the diaphragm because from what i read the "0" marked on it should be facing the rear of the engine if at the stock position

btw im getting 460-480km's to the tank. is this normal?

let me know
thanks a bunch!

Careful...A big increase in power will be because the pump was shot or almost shot. When dropping over a grand you want to make sure it's needed before assuming your experience will be similar. I would hate to see folks running out and paying for rebuilds that aren't needed. If possible drive someone else's to make a comparison before making that call.

Mine has been leaking since I bought the van. Lately it seems to be leaking worse and at times it feels like I have a bit of a lack of oommpf. I'm going to get it re-built and do a timing-belt change at the same time since I'm approaching 200k.

[thedjjack]

Personally you will never get much power out of the 2.5L over stock. If you want to go fast save you money and put a V8 under the hood ... you can upon the exhaust, you can turn up the turbo, you can rebuild caliper the pump and rebuild the injectors... Honestly if you want more power the 4m40 series motor is going to make you much ... Sell the current and get the 2.8L newer version.

Currently I am enjoying my mint $300.00 AWD 1997 Ford Explorer with the factory installed 5.0L mustang motor...you could never make the 2.5L diesel move like this thing (but I only get 18mpg)...

hi, mostly over the year this injection pump seal leak because of the low sulfur they used in diesel now.
no lubrication.
you need to see and find who really do know how to rebuild the proper spec on this pump.
been thru many local bc injection pump place but unfortunately they cannot put the timing and power from the old one.
don't know why. but no I send all me pump in asia and works really good perfect timing and full rebuild thru a injection pump specialist who do this type for long time. they put it in the machine and result is wow like new again no smoke and runs smooth and more power.
when pump has leak u loose pressure and lack of power
cheers

I wanted to know what speed and rpms you guys are running going up hwy 1 cut in north van.

Drive a '92 Chamonix Starwagon with the 4D56T motor, no intercooler. I do the Cut (the great acid test) at 80 kliks; RPM at three grand. Typically the water temp gauge begins to rise near the top from it's running position at about a third to half on the dial. I find that with driving my little diesel, that by keeping the revs high the coolant circulates more and cools the engine more effectively. When I get to the top of the Cut I keep her in third gear a little longer, say to the Lynn Valley exit, this helps bring the temps down a little sooner.

The 4D56 is not about speed, more about balance and torque. Can cruise quite comfortably at 120 but goes through a great deal of fuel. 105-110 is the sweet spot and typically gets me eight or so litres per hundred kliks on an open highway, such as the Number One out to Hope.

Drove the Space Gear (with the 2.8 4M40 & intercooler) up the Cut and she did 100 kliks without batting a headlamp. Temp didn't move, don't recall the RPM.

Thank you for answering my question Falco !
Mine does pretty much the same speed at the same rpms and same fuel consumption so that's good to know.

Any thoughts on the fuel diaphragm/deli tune?

[FalcoColumbarius]

....Any thoughts on the fuel diaphragm/deli tune?

Hmm... I've had the Deli Tune done... I think it was in 2008? I've had no complaints. Having said that I've also held the belief that if it ain't broke, why fix it? Regarding whether the diaphragm is included in the Deli-Tune, you'd really have to talk to the lads at CVI and then you know for sure... smiles.

all a deli-tune is, is an ultrasonic cleaning and balancing of the injectors. I think Butch ups the IP pressure a tiny bit. Hardly say this makes for a big improvement unless you had a big problem to start with. (I had CVI do this on my first P35)Added boost pressure with increase of fuel pressure will net the best performance gains and its free. (but should only be done by those qualified for such tweaking) EGR delete and a larger flow exhaust/snorkel will help off line performance. (total BS about 300 degree temp drops) Water injection hardly makes a difference on these little diesels. (especially for the cost...I tried different ratio's of water/ethanol etc..) Narrower tires with higher air pressures, (225 width or less...friction/drag is your enemy) and less weight (rear seats etc..) all help.
I have done all the mods above on three seperate 92 L300's over the years on each. Heres my summary:
EGR Delete (less fouling of your newly cleaned injectors)
2.5 Exhaust..simply breaths better..sounds good too!
Up the boost (14-16psi for a sound engine is a safe number)
Small increase in IP pressure (easy to get this wrong, and if you run it too rich, say goodbye to your head with the increase in temps)
** Use a pyrometer to maximize the vehicles potential!!!..driving these without one is rediculous!
Find creative ways to drop weight....
