Ford & Mazda Ranger 2.5 TD turbo

[BushMan]

Hi fellow Ranger owners,
I have a 2004 2.5TD DC Ranger, now my question is can you actually tell or feel your Ranger's turbo kicking in, on the Toyota D4D I can definitly feel it but on my truck I can't realy tell if it kicked in or not

Hi Bushman

My truck is very much the same..can't really feel it..I have also driven the 2.5 D4D and it is quite different...can feel that asthma pump arriving at the party ;P..

Mine sounds pretty cool though!! ;P

I've driven a few Rangers and can definitely feel it, although on one Ranger I had (a single cab) it was much less pronounced- perhaps because the vehicle was lighter. Haven't driven a D4D so can't compare.

If you accelerate gently from 1300rpm in 4rd gear or so, you should get a nice surge around 1750. Essentially the motor cannot generate enough torque to pull the skin off a rice pudding at 1300, but is pretty strong at 1750 and very strong at 2000.

Alternatively, if you accelerate hard from steady state 2000rpm, you should get a certain amount of acceleration immediately, then a step increase about a second later courtesy of the turbo.

Also, if you can run it to at least 155km/h on a GPS (could be 170 on a speedo depending on your tyres) then your power output is what you should expect and your turbo is working.

Not really...and not sure what the previous comment was as even below boost the diesel has more than enough torque to climb...just depends how fast you wanna get there..when I off-raod I like to go as slow as possible and as fast as I need.

A WELL matched engine turbo gives you an almost seemless power/torque curve unlike the 2.5 Navara,dead then hits like a train to get that peak power.....pointless on the dirt...but anyway...The variable vein turbo does just that, give you that smooth pull...

MOST turbo passanger and bakkie TDI's pull from as low as 1400rpm but usually around 1800rpm..

By the way..if you have the 3.0D4D, that motor pulls ALOT harder than your 2.5

Most Certainly felt the kick from 2000 rpm on ...
Feels a bit slow and laggy up till 2k rpm then it pulls all the way to 3/3500 rpm

Most important on TD is to make use of the boost and slick shifts... to keep it within the boost and torque ...
kW not much use on the TD

1>2 3000 rpm falls back to 2000 rpm ( in boost and torque )
2>3 3000 rpm falls back to 2250 rpm +-
...

Can't remember all exactly was sold last year

Also keep in mind that the 2500TD/2.5TD
Is the older gen Diesel Turbo's...

TDi, D4D, TDCi etc... all newer Common Rail / Direct Injection / Variable Vane Turbo Charged Motors

Variable Vane Turbo on D4D, TDCi, TDi causes the Turbo to spool up faster and supplying the boost from +- 1450 - 1750 ( lightly ) more Pronounced Boost from 1800 rpm On

Common Rail on most newer models also contribute and uses very High Injection Pressure rails.

On the Newer Gen. TD's it is preferred to use ULS / 50ppm Clean Diesle

Set of nice and easy in 1st, put 2nd and put your foot flat to the floor, it will lag like a biatch, then at about 1800-2000 it will pull like a train, if not then somethings seriously wrong. infact for you to be asking this question, something must defantly be wrong!

That nice "kick in the butt" is not simply caused by the turbo coming on song - the biggest contributor is the injector pump restrictor / limiter (older technologies refer to it as an air-fuel ratio control),either mechanical or controlled by the ECM, acknowledging increased boost thereby allowing a fairly drastic increase in the amount of fuel injected.

Depending on design the reasons for the low-RPM restriction could for instance be to lower stress on the internals, or to limit the amount of black smoke from the exhaust.

Some engine designs do not display any perceivable kick but simply a smooth, increasing pull as the revs and load rises, others are relatively dead to a point and then all the action starts. The higher the boost setting, the more marked the "kick" tends to be. Variable-vane technology helps to lessen the kick by allowing better power from lower RPM's throughout a larger range.

It's one of the reasons why I simply LOVE diesels - the knowledge and feeling of POWER without having to wrench the guts out of it....

Good day

There is a small siv you might want to have a look at (it might be clogged). it is on your diesel pump. Ill get the documentation and post it tomorrow. If that doesn't work you might want to refurbish your injectors and calibrate your diesel pump.

I posted step by step pictures of how to clean out that sieve. Just go do a search. It was a few months ago.

I can also hear the turbo slightly when i drive with the cab window open at the back

Hi all

as always you get the best advice on
this forum

My question is , is it worth the effort to do free flow exhaust and pump tune up
SAC quoting R2600) or will this be a minimal improvement

SAC quote some impressive figures an xtra 30 KWand pretty good Nm aswell but ihave already done 198 000ks and am just hoping one of the knowledgable guys can give me some advice please

thanks guys

[Hilly]

Sorry guys i did not mean to pose this query in yhe middle of some one elses query i just hit the wrong button

my appologies

Hi everyone, recently bought a 2005 2.5 tdi 4x4 Ford Ranger. Really happy with it except that its a bit slow compared to friends non 4x4 version. (same year and model) Is there a diffrence in performance between the 2 ? I have been told a Sirus intercooler and a exhaust system with the correct downpipe from the turbo will do the job. Apparently 100 nm more, can anybody advise on this ? thanks

If I have to repeat myself !! it is going to be the 4th longest thread on the forum !! go find my Ford second longest thread and you will get all your answers.

1. Have you cleaned the secondary diesel filter? If not, do so.

2. Search 'Ford se tweede langste thread'. DVR explains exactly what to do iro performance.

To Jaco Neetling.
The 4x4 have much more drag on the front sideshafts the are constantly turning compared to he 4x2. This is the reason most 4x2's fuel consumption is less than the 4x4.
