Hi all, I know there has been a lot of posts and varying opinions on fuel consumption. A recent comment by Coldy said he was getting around 9.5 on the highway in his efi sedan,that was much better than my TP Wagon gets around town., and better than what I would think mine would do on the highway..Today I had the chance to head down the South Coast from Sydney,had a good run,pretty much highway speed for the most but still the usual stop start around Sutherland...and of course a pretty big climb when heading back to Sydney. To my surprise/relief she got 9.7 /100km. I was pretty happy with that considering I sat in 3rd gear heading up the bigger hills and it really seemed to pull quite well ! The roller cam engine seems to make a bit more torque around 3000 compared to the old engine. I was running E10 junk fuel and filled it prior to the run and then topped it up on return and measured the distance on the trip meter,so it should be a reasonably accurate reading. Next time,I might fit a set of blue injectors in her and see what difference they make. Anyways,hope this is of interest to us first gen dinosaurs! Cheers

Fuel efficiency increased slowly with newer Mitsubishis. The worst is the Sigma and first gen 2.6L carby cars, EFI ones are better, the 12 valve 3.0L V6 better again, and so on. The 3.5L third gen will get you 7.7 on a long trip if it is an auto sedan. The same engine in a wagon will use more petrol. Current crops of Mitsu engines are better again, the 2.0L variable valve 4 cylinder engines get about 7 to 8 around town, lower on the open road. Not bad for a 2.0L that puts out more Kw than the Astron 2.6L engine.

Best trip ever Friday.
Brimmed the tank and set off home. 740km later brimmed the tank and could only cram in 62 litres!!!
Holiday traffic the pits so without 1 hour of bumper to bumper may have been a shade better!! Was a cool day so did not use the aircon as much as usual and the car was lightly loaded also not normal. Vee

fit the blue injectors . . rubber grease on all 0 rings

found suppliers in other posts below

fit the blue injectors . there is a difference . rubber grease 0 rings
new 0 rings (Dont know of a supplier ..repco no go last time I enquired ) .. dont know why ?

Do you need to increase fuel pressure with the blue injectors?

That's pretty darn good...I'm impressed! What's your setup? Blue or tan injectors? Sedan or wagon? Type of Flux gate capacitor used?

Thanks again Magna Buff....I'll get them serviced,that way the o rings will be good and I'll know they are good set. Will let you all know what happens. I think the spray pattern of the blues should help...only one way to find out!

no need to replace the fuel pump

Thanks Magnabuff, so I guess the part no. IRK 711 are the blue ones, interesting to see used by Ford BMW etc also

found more current data for 2014 in posts below

That's pretty darn good...I'm impressed! What's your setup? Blue or tan injectors? Sedan or wagon? Type of Flux gate capacitor used?
Tan injectors Tp Wagon stock standard.
When you consider the 740IL BMW that i followed and delivered back to owner for the whole trip got 8.6L/100km and thats a whopping V8 the ole 4cyl Magna was not so crash hot!!!

IRK 711 is all I can find that will fit a TN-TP injected

cannot find old injector flow rate charts and comparisons avail in 2005

should have printed a hard copy

Fitting bigger injectors does not always guarantee bigger flow. Very dependant on fuel pressure and the blue injectors fitted to TR onwards worked with a higher fuel system pressure to achieve the few KW power increase over the TN-TP injected engines and better emissions. Vee

It really doesnt matter today as you can only buy the one injector that fits TR and TN -TP

there is a fuel pump motor replacement not the sender

I cant find data on the IRK 711 injectors ..

..

Can a TR-TS fuel pressure regulator fit or be modified to fit the TN-TP?

Can a TR-TS fuel pressure regulator fit or be modified to fit the TN-TP?

I'm not 100% sure,but I'd say no,the fuel rails are totally different.

we better work something out fast

bosch have the parts covered but at this price

New * genuine * Mitsubishi Magna TN TP 2.6L 4G54 Fuel Pressure Regulator FPR AU $160.00

this is the only one that fits both TR-TS and the TN-TP

New * genuine * Mitsubishi Magna TR TS 2.6L 4G54 Fuel Pressure Regulator FPR AU $132.00

regular TR/TS
Fuel pressure regulator bosch 0280160519 mitsubishi Magna TR TS 2.6L 4G54 AU $55.00

if you get the chance to lay both rails togeather

we all better find a mod to either fit the cheaper TR- TS regulator to a TN-TP rail
or fit the TR/TS rail to a TN-TP inlet manifold

we better work something out fast

bosch have the parts covered but price man get real

New * genuine * Mitsubishi Magna TN TP 2.6L 4G54 Fuel Pressure Regulator FPR AU $160.00

You could probably buy a cheap adjustable reg for less,have to sort out connections but at least we could bring the pressure up to the TR,TS spec with blue injectors. Mind you,how often do they fail? My pump and reg are the originals....the pump is quiet and runs fine,but I often worry it's going to give up the ghost at a bad time.

acheiving TN-TP EFI fuel economy is very important

seems a reasonable research topic for 2014
I prefer facts and confirmation of source

fuel pressure regulators
They just stop working and no one is the wiser ..no fault codes as its a vacumme device

symptoms can include..
fuel figures slowly drop off very slowly ...... engine will still run without it working but has to be fitted
regulator full of fuel
you think the cause is
injectors
fuel filter
fuel pump
fuel filter
maf

whats available 2014 ................... who wants pictures
about fitting ......... you will need to thread the TP-TN fuel rail 0 ring end or something

fuel pressure regulator required to work for 265kpa = 38 psi .. as this is the pump figures at idle

carby ones are too low a pressure -

proflow pfe 13129 compact EFI bypass fuel pressure regulator fpr reg adjustable $145

EFI adjustable fuel regulators are made for racing and turbos specs

TN repair manual -fuel pump pressure at idle 245-264 kpa

TR/TS repair manual - fuel pump pressure at idle 265 kpa

fitting a TR fuel pump is the owners call
If fitting blues to a TN-TP I would fit a new fuel pressure regulator 265 = 38 psi

convert http://convertmpatopsi.com/kpa/convert-kPa-to-psi.html

This will need pictures

up grading to the M9 head was neat

Intresting research actually all of this...... lots of experimentation in sigmas and pajero with EFI conversions and fuel rails

when doing sigma and pajero efi conversions those guys were brave eneough to weld a and modify fuel rails use different injectors avail
sure hope they got the job right to maintain the fuel pressure in the rail to specs .... again no resolved posts or feedback

also found a a dead link to a pdf factory manual for the TN EFI lost info

spacer just to fit in the end of the round TN-TP fuel rail to fit the cheaper TR-TS regulator
then a mounting plate for the screws if required

hoping to find better pics of fuel rail ends and regulators
TN-TP is round ... large 0 ring for fuel pressure regulator
TR-TS is flat ... small 0 ring

Seems like the TN-TP and TR-TS pressures are almost the same, so keeping the original one might work ok

Hey Magna Buff,thanks for all the effort your putting into the research...great stuff.
Dennystone....I have a set of blue injectors that came with the roller engine I bought. I fitted them into the old engine in the car while I was rebuilding the roller cam engine. They ran fine, I never did any economy testing because I didn't want to drive too far on the old engine. The new engine is in the car now but with the tan injectors. I'll get the blue ones cleaned in the next week or so and give them a run. I'm not expecting any issues,should run fine,but I'm really interested to see the economy difference.

Hi Tpwagon, I think what we want is better fuel economy. I fitted a TS motor in my TN, had to change the engine mount plate and of course inlet manifold

We tried to fit a second gen inlet manifold into the TP engine bay .
the TR plenium didnt clear the fire wall eneough. bonnet was close too
.. then the TPS and Maf working out wiring ..... to run on TP specs was a nightmare

next idea was to cut and weld the plenium end with a custom plate so the TR throttle body may fit ....no qualified welder was willing to risk it years ago

a certain falcon throttle body onto to the TP plenium / that was close ..... it went no further

E10 is bad for the first gens over time . if used a lot ...fuel filter changes need to be more frequent

iridium plugs help with better fuel economy on a TN- TP
use thicker plug leads - 8.0mm
replace 02 sensor
rotor and dissy / coil and exciter can fail sometimes (very few Pickup hall sensors fail )most TR-TS stuff fits
clean air filter as required

Check the MAF it has several functions (cant find a new supplier )
adjust the TPS to specs (auto)
Timing and idle within specs
Idle stepper motor works fully (cant find a new supplier )

The oil pump / balance shafts chain has an adjustment ( Do this annually )
(a metal cover) on the timing cover below the alternator level

Make sure the hydraulic tappets are not leaking or hammered (TR-TS ones fit )

I stripped a 520i BMW a while ago and now doing a 535i, one has a 2 litre 6cyl. the other 3.5 litre, both fuel pressure regulators have the same part number, so I'm sure can use the TN-TP regs. with the blue injectors

Hi Magnabuff, what's the difference with a M9 head?

Pretty sure the M8 head was on the later TS engines...it had the more modern heart shaped combustion chambers that are common on modern engines and a slightly higher comp ratio and dished pistons. Better economy maybe? Probably better emissions and less detonation prone design.

you can fit a M9 head with TP block flat pistons ...
its been done by a TP owner in this forum heres the link with pictures

Pistons nice

I don't think the main reason these injectors make a difference is due simply to the size difference.. I think some of it comes down to the spray pattern (which may or may not be slightly different), and possibly the mechanical design being slightly better. Even if not everyone notices a difference, I certainly have, and stagma also has. There is no way I would ever consider putting the old injectors back now as I have not found a single disadvantage with this mod.

Even if not everyone notices a difference in fuel economy, which is obviously dependent on the condition of the car and the mods it's had done, stagma and I have both noticed that there is a noticeably smoother idle, response seems to be slightly better and the fuel economy has increased. The whole point of my recommendation is to speak from my experience of performing this mod, and that it has the potential to improve fuel economy, performance and improve the idle. I am not saying to anyone that they must perform this mod, as it is their own choice whether they feel it will offer advantages or not. For those however who are considering something like this, yet are unsure whether it is possible or whether it helps with anything, this is simply a recommendation and an opinion. I cannot guarantee this mod will show the same advantages to everyone who performs it. However - whether or not it improves anything, as far as I can tell, it doesn't degrade anything either.

The second gen 4G54 magnas all use these injectors, and their fuel economy and performance is better than the stock first gen. That said, there must be something they did right with these injectors.

Good point you mention about E10 in these old girls...didn't give it a lot of thought,but I filled up with normal unleaded the other day,it does seem smoother,wonder if it helps economy? I'll drop my blues into get them cleaned this week,fit them over the weekend. I have a trip coming up to head down the Coast again,exactly the same drive as last time so I'll do a comparison. I'll run E10 on the trip coz that's what I used last time,that way things are equal.

To use the forum search you have to know how the topic was typed in started
E10 or ethanol on a search comes up empty

its hard to search this topic down for first gen on the web also

... doesn't help first gen owners much

E10
so around 2009 it was introduced
E10 is most commonly blended with 91 RON "regular unleaded" fuel.

A very helpful write up

My last lot of beige injectors i got exchange thru Bursons. Probably posted here somewhere at the time i think less than $200 they were for the set.
I see them come up on ebay international occasionally they fit some Euro cars as well as early SS Commodores i think it was or HSV.
No problems with them they are going strong!! Vee

With the introduction of unleaded fuel, vehicles produced by MMAL and MMC for sale and
operation within Australia have been designed to operate on unleaded fuel with a minimum
octane rating of 91 RON.
Ethanol blended fuels are not recommended by MMAL, however should they be used then a
mixture of not more than 10% ethanol (grain alcohol) and 90% unleaded petrol may be used
in your vehicle, provided the octane rating is at least as high as that recommended for
unleaded petrol.
NOTE: Poor quality fuels or ethanol blended fuels in excess of the 10% ratio can cause
problems such as hard starting, stalling, engine noise, hesitation, increased fuel
consumption and possible fuel system or engine damage.
MMAL reserves the right to deny warranty for any failure or operational condition
attributed to the use of poor quality fuel.
The attached chart should be used as a guide to the use of ethanol blended fuels in MMC
and MMAL products produced for the Australian market.

Thanks for the E10 info Magna Buff!

OK,so I fitted a set of blue injectors. Here's the deal...TP Elite Wagon,still has factory roof racks etc so I'm sure it all adds a bit of drag. TR roller cam engine,M6 open chamber ( normal style) head. Engine rebuilt 5000 Km's ago,trans is very good and lockup works perfectly. With a set of Tan injectors I got 9.7/100 km on a drive down the South Coast . With the blue injectors fitted I did the same run today,here's what I found...by the way,all injectors,both tan and blue were serviced by the same guy and all deemed to be fine.
1/ Economy,I got 8.5/100 km,much better!
2/On the climb up the mountain it seemed to make more torque with the blues,I gave it a bit more stick,but it responded very well for a 2.6 in a biggish car,I sat in 3rd,pulling about 3500 to 4000 rpm and it accelerated up the big climb very well.
3/ idle may be a tad smoother,but that's a pretty subjective observation.
4/ I ran the blues in my old engine for a while ,they were not serviced at that stage,didn't really notice much difference,but they were dirty,the tans were too...and the chains in the engine were knack erred...so hard to really say much about stop start economy...either way, I think around town economy will never be flash in a first gen!

So there it is,the blues are staying in,I tried to compare as fairly as possible,I personally believe the blues do have advantages,mine came with the TR engine,but the cost of buying a set may take the shine off using them for some. Cheers guys,hope it helps! Steve

welcome to the blue club .. each first gen owner in their own time has to try in their cars first .. to be sure its not bullshit from past members

timing is the same iridium plugs next if not already fitted

I guess no one wants to swap my set of tan injectors for a set of iridium plugs do they?? Anyone?? Mmmm,didn't think so! I've got a feeling I have a spare set of new standard plugs here,guess I'll use them up first,but will give the iridium lugs a try when I need to buy some. What is the correct number for them?

I was very happy with the economy increase with the blues,I gave it a fair bit of stick up the climbs,if I broke even I would not have been surprised...it's not the ideal drive for steady state economy runs,but pretty real world I guess. I'm hoping for even better on a flatter drive,it wouldn't surprise me if I get into the low 8/100 km area...hopefully.

you can get other makes but i have used these

http://www.ngk.com.au/spark-plugs-part-finder/passenger-and-commercial?PageMode=Results&Make=MITSUBISHI&Model=Magna+TR&Year=04%2F91+-+03%2F942.6L4+Cyl.4G54

ngk BP6ES 0.8
ngk irridiun BPR6EIX

same number as the TR/TS plug iridium and run the 8 mm plug leads

now those thicker plug leads wont fit into the plastic locater rails of the TP without breaking
so zip ties will be required

Actually ,I checked the leads the other day,I'm running Eagle 8mm leads on it already. Had them for quite a while now.. Strangely they fit into the factory clips!

The last set of leads I bought was for my carby sedan and I specifically bought 8mm Magnecor leads because the previous 6mm ones were too loose. For one of the cars (don't remember which one now), I made up my own lead separators by cutting them out from a piece of nylon kitchen chopping board.

I hadn't checked my fuel consumption for a while because of not filling the tank but last week and this week I filled it. It cost $25.20 at 154.9 cents per litre for 170kms. That works out at 9.57 litres per 100km or 29.5 mpg. I'm pleased that the economy hasn't deteriorated.

If you want the best plugs get the ones from the guy in Yorkey's Knob who sells the HiClones.
