Alfa GT 1.9 Q2 injectors Upgrade


I'm Giuseppe from Italy (sorry for my english) and I have an Alfa Gt 1.9 Jtd Q2 150hp.

At the end of this month I'll upgrade my car with a bigger diesel pump, big turbo and remap.

Now the car have a free exhaust, front intercooler, big turbo (but I don't like it), no egr and remap.

I hope to arrive around 250hp, but the problem are the stock injector that are too small for this upgrade. Injectors code is 0445110243 and nozzle is DLLA148P1347

Can you tell me which nozzle is better for my car? I drive the car all days, so no too smoke and no too consumption

Thank you

Easiest option would be:
0 445 110 308 from 2.4 210HP

Or a better but more rare/expensive option:
0 445 110 341 from 1.9 170HP

I'm not expert, but I used to have those ...243 ınjectors. In here we have a thread You can fıt 0445 110 308 Injector from 2.4 JTDM 210HP I think. Or You can use ...308 Nozzle and Needle to fit on ... 243 body. And IMA coded to be matched. Right now I'm using like that

Thank you for the answer

which is the difference between the 243 injectors nozzle and 308?

Holes number are the same?

What is your benefit when you know the number of holes or the hole diameter?

The 308 flows a lot more then the stock injectors. People use this injectors for 300hp and more. Opel/Vauxhall guys use this injectors with crazy 2100 bar railpressure (i wouldn't do this)


This 3 injectors are mechanical the same. The 308 have the right ima codes for the EDC16. 299 und 327 need new ima codes as a 308 injector. Some diesel services can do this. I have 327s with 308s generated ima codes.
327 are very cheap and easy to find.
