4m40 turbo upgrade expressions of interest

[Mcreight911]

As most of you know I have been playing with different turbos on the 4m40 for a few years now. There has been a lot of interest and I get lots of PM's and emails asking for options. Some people like my Advise and some don't . I'm getting to the stage now where I am comfortable offering a few turbo options, depending what people want . So far I have tested one offs and won't offer some option unless there's enough interest. All options use a bush bearing waste gate turbo .So I guess I'm asking, what do the people want ?


Option 1 up to 100rwhp tuned standard setup.

Option 2 up to 120rwhp bolt on turbo and tune.

Option 3 up to 140rwhp turbo with a manifold adapter and different patten dump pipe. An upgraded intercooler and exhaust is also required to make the quoted power but will work without.

Option 4 up to 200rwhp. Turbo, new manifold to suit turbo. Will also need pump mods, intercooler upgrade, exhaust and airbox to make the quoted power but will work without.


The bolt on option is the standard Turbo hi flowed. More power than this requires a different turbine housing as the standard on is to restrictive. This Requires a manifold adapter or new manifold .

Obviously these are max figures. Condition of engine, and fuel system will alter results . If your considering any power upgrades and your not sure about the condition of your injectors get them reconditioned or get new ones . This is a must. Warn/Out of spec injector are one of the main causes of cracked heads on the 4m40

Price for the hi HP turbo is a bit more than the average rebuild on a standard turbo . Due to forum rules PM for price . Can do deals on group buys as I have to put in a minimum order quantity.

Due to lack of interest I no longer keep kits. One off orders of my customised turbos ant available either as parts need to be ordered in minimum quantities. However if you need turbo sizing help I can advise on what off the shelf options would best suit your needs . Happy boosting ��

Hi!

I hope you can give me a little guidance or confirm whether I'm on the right path.
Also, I guess this information can be very useful to other members and Pajero owners in general.

Last year I upgraded my stock TD04-12T turbocharger which was working just fine at 19 PSI for some months (before that it was running at stock boost and fuel).
I decided to go the Kinugawa route. I purchased and got installed the 'Monster' TD04L-15T and I had it running at 20 PSI.
My Pajero, even though I later found out that the engine wasn't at it's most, was pulling amazingly well, regular car performance if not better. The thing started boosting at around 1.200 RPM and boosted all the way to the redline.
Just perfect!

Later I discovered that I was burning oil and I had the engine disassembled by a professional.
All OEM internals from Mitsubishi (pistons, rings, bearings, gasket, etc). Cylinder head is the one I already had, a two year old AMC unit.
When the 'new' engine was assembled we found out that the turbocharger had shaft play (check the following video). We didn't check this beforehand as the unit was purchased on july 2018.



Right now I decided to downgrade to the stock TD04-12T I had removed last year so that I can drive the car.

The turbocharger specialist said that the TD04L-15T (Kinugawa 'Monster') is a very fragile turbo as the shaft has a lot of pressure spinning the big inducer wheel with the small exhaust wheel as this is a hybrid turbo. He also mentioned that he didn't think the overall quality of the Kinugawa turbocharger was good.
He can fix it but he can't give me warranty for the job.

The question is: should I had the Kinugawa core replaced and rebalanced or go with another alternative? If there's a better alternative which is it?
I'm after good power levels (as high as possible) but I do want to have as much low RPM boost as possible as I mainly use the car for city driving. I don't need and I don't want to do 200 kmh in my Pajero :-)

I would appreciate any help or guidance.


Thank you!

Hi there, quite new to this forum, but not new to hotting up Mitsubishi diesels. I've tried a few different turbos over the years, ranging from hi flowed stock turbos to Subaru sti jobbies. My most recent is a IHI gated 44 turbo with billet 6+6 front wheel. These turbos have had good results on the Isuzu 4JJIT motors. This is on a 4m40t. Will also be trying a new incarnation of water methanol injection as well, which will incorporate pre turbo and post intercooler axial injection points.

Water meth injection works quite well on any diesel . I did run pre and post turbo for quite some time. Mostly just water as I was lazy .

The ihi with the 44mm turbo is a bit big for the 4m40 in my opinion unless you have a modded fuel pump and are looking for more peak power.

My 200hp combo was a similar turbo based off a tdo4hl but with a compressor around 43mm and a different design 11 blade turbine . Daily tune was 203hp at 28psi.

[Meth'd_up_Mitsi]

Once I find the damn tacho wire I will be able to tell you what rpm it starts boosting at.. but it feels somewhere around the 1500rpm mark..
Problem with water is you ideally need 30psi for it to be instantly evaporated. (According to the experts) Which is why they mix methanol in to greatly increase water's evaporation rate. I buy my drums in 200L lots @ $280 a pop. I've experimented with ratios as high as 25:75 water methanol mixes and the grin factor is hard to ignore. Especially when you're tired of embarrassing td42 & LandCruiser V8 owners and have start looking for more exotic machinery..
