What injectors for 1.8T ?

[marto7]

Hello.Im with 1.8t Quattro BFB engine and need injectors for my bigger turbo that i will put.I need 630cc but dont know if choosed the perfect one.Im wondering about Bosch 630cc EV14 with number - 0 280 158 298.Are they with perfect spray patern for that engine ? I know Bosch are better than Siemens deka and have better idle.

I run Bosch 550cc EV14 they have no problems with WOT or idle, very good injectors. Many 1.8t 2.7tt builds run the EV 14 550cc, 750cc or 1000cc people have good things to say about them.

I believe Siemens owns Bosch now, food for thought.

I know 550cc is good but dont know if the 630cc 0280158298 are the same but with more capacity.Where can i compare them ?

the right injectors are always the ones your tuner prefers/supports. Tuner first, then injectors

[marto7]

I talked with some tuners and everybody says it is same for them if i get 550 or 630 and bosch or siemens.I will get Bosch ev14 630cc

Injector dynamics 1075X or 1000's. 3 bar fpr with b5 fuel rail and converter to a system wit ha return and call it a day!!

Why so complicated and expensive.What would be the difference between only bosch 630cc vs ID 1000cc with b5 fuel rail and another FPR ?

if you don't need the additional flow of the 1000cc injectors, then you're just paying for capacity you don't need.

I run the Bosch 630cc (unmodified) with a B5 rail and 4-bar FPR, FWIW

[marto7]

550cc on 3bar is enought for me.I will get 630cc to be extra sure and dont need another fpr.For what about you getting B5 rail

4 bar is stock, so no reason to drop down. Just use the rail and FPR from an AWM (2001 B5) as it bolts right up to the B6 manifold and fits perfectly (unlike the AEB rail)

I am with A4 B7 2005 year with BFB engine.I thinked it is 3bar stock pressure.But cant i use my stock FPR and rail ? They cant fit or what ?

wait are you working on a b7 or b6? B7 is 2.0t DI ?

I have been working on my 2001.5 B5 (AWM) for years, and may have an extra rail in my parts boxes if you need one. I think I pulled a junk yard one at one point just because.

Ooh Ok, I did not know any of the B7 cars had the 1.8 BFB. learn something everyday I guess. thought stock HP was 180 ?

You only need to change your fuel rail if your converting to a return style fuel system.

Why do i need to do that ? Do i need it ? I have Walbro GSS340 fuel pump and thinking to put it on the stock fuel pump place.

@GOODBYNAAIR - No its not 180Hp.Every BFB engine is 163Hp.

Depends on how much power you’re trying to make. Higher fuel pressure means more fuel and better atomization.

[marto7]

I will put K04-064 and expect maximum 360-370hp on the engine in the perfect scenario.
