147 Q2 mods

Hi guys, I see this topic is brough up quite often - but here's one more time, just to make sure. I recently got a 147 q2, and now I am on a mission to upgrade it. Unfortunately, since I am quite busy, I don't have enough time to do it myself, and am too impatient to wait long enough until I have some spare time - so most of the work will be done in a garage - with me supplying the ideas and the parts.

What I would like to do is the following:

- complete exaust overhaul - EGR delete etc etc - not sure about everything that needs to be done there, any advice is welcome.
- FMIC - as far as I understood, for any serious tuning this is a must
- complete new map
- bigger turbo, something like GTB2056V
- maybe an LPG injection system.

From what I read, this should be fairly safe to pull of for 24/7 driving, and should take the car to around 250bhp...

Question is - what do you think - any feedback and advice is welcome...

Cheers

LPG is already said is not a very good idea...if you want to add something to the diesel fuel, think about WM injection.

Thanks for your answers, LPG injection is scratched off the list the stage 1 is booked to be done this week, so let's see how she goes afterwards

LPG in a diesel is also in its infancy stages. Same as direct injection on lpg.
Just not worth it when you can get better results in cheaper methods.

GTB turbo kit,FMIC and freeflow 2,5" exhaust are the most essential hardware mods.
Besides that, an upgrade of sensors is recommended, so 80mm maf and 3.5 bar map.
This, with a proper remap can take you to 240 hp.

WMI can bring an additional 15hp, depending on the kit you take.

Hi JS-JTD, do you have changed the injectors for your impressive resoult?Now I have 200hp but I want more, about 240hp on gtb2056v. Could you recommend the best solution to reach the power what I want?

Better injectors help a lot with keeping EGTs low...

You could fit 2.0JTDm injectors or "ducati corse" injectors to your ECU, but you will not be able to program the calibration codes of the injectors, without modifying soma parts the ECU software.
And without calibration codes, things are not optimal.

I know that ECU must be modified, I also order MAP 3,5bar and I need bigger MAF. But question is about injectors. I browseing italian ebay and there is company Racingtechnologies which sales on ebay turbo kit with Corse injectors. I ask them about that, but they silence...ok I understand is know how, but I ask them about the price only for injectors and they no answer jet. That turbo kit is priced about 3000 euro Turbo + four Corse injectors, I think it is too high. They said that kit can produce 100hp more than OEM, of course only if your engine is in good condition

No...

There are three types of codes... CF3 (140 and 150HP JTD multi-jets made before 2005), CF4 all 1.9 and 2.4 JTDm engines made between 2005 and 2011, CF5 all 1.6 and 2.0 JTDm engines.

And those codes are not compatible between different types. But there is no problem programming 2.4 CF4 code into 1.9 CF4 ECU or vice versa.

I would not recommend you buying modified (or upgraded) injectors because you will end up with injectors that you will be unable to get calibration codes for them, or any usable data on the injection duration parameters.
And that will make it very hard to use the injectors in optimal way.

Those injectors are good for racing cars, but not for daily use...

Hmmm, second hand GT2256v charger...

I'd take a new GTB2056v unit, it's a much more advanced and capable turbo.
Then, after you do fmic, exhaust and sensors you can think about injectors. Cf4 170/210 hp ones are easy to find (0445110299 /...308) not too expensive and flow quite a bit more than cf3 16v ones. As TribesMan says, he can make it work softwarewise.
Then 240hp should not be a problem.
I use Ducati injectors myself, but these are very rare and expensive. I expect to have nearly 280 hp atm with my latest mapping. WMI included that is.

147 JTDm 16v - GTB2060v - 329 hp/578 Nm

In Poland I have occasion to buy injectors from Brera 2,4. It will be fit? You said 210hp, so i think it will be good, but first I ask you about opinon.

Mechanically they will fit just fine. You will only have problems with programming codes into the ECU, if you don't know how to "convince" the ECU to accept CF4 codes.

do you need to copy the codes table from a cf4 ecu into the cf3 ecu?

Not really, codes table has to do nothing with ECU accepting the codes, it is used "only" to calculate proper correction values from the codes. So it is necessary to copy codes table to have everything working optimally, but it will not be enough for ECU to accept the codes.

There are a few other bits and things that need changing...

Yes I obviously know how to do that.

Wow, thanks guys for the great advice. So after carefully reading through this, the decision is the folowing:

-intercooler already ordered.
-will try to find a second hand GTB 2056v turbo, I know a great company that does magic in repairing them (in case it needs a bit of work).
-free flow exhaust will be fitted - EGR blank already bought. Since the regulations are not so strict in Serbia, DPF will also be removed.
-80mm MAF and 3.5bar MAP sensors will be fitted.
-after the remap, depending on the results I will probably buy some bigger injectors as well..

Work on the car is started, can't wait to see some results.

Again, thank you all for the great advice..

iF you want very good lasting and performance i suggest you to buy a new turbo. But it depends on you and ...the money what you want to pay.
