good for fuellin a td04 at 1.1/ 1.2? found some fairly cheap and wondered if they'd fuel or will 330s be better? some pople said standard. some people said 550s incase i upgrade size ofturbo. i want the injectors for td04. if i uprgrade i'll run bigger else idle etc would be horrible i believe. cheers

315cc pink are 30.9lb/hr at 2.9 bar stock injectors will flow 309cc at 2.9bar so I don't see why you would bother. It may help if you gave some more detail about your fueling setup.

i've always thought standard injectors were 295cc. these are twenty cc's bigger so didn't know if they'd fuel a td04 nicely. running a walbro n emb. full td04 setup plus supporting mods. runnin .4 bar till i can sort injectors and then get it mapped. so the extra twenty cc ain't worth it? but most people run 330 which is only15 more. cheers anyway.

Better off going for bigger then you can reduce fuel pressure/duty cycle. 315's at 1.2 bar will prob max out.

Stock are called 295cc ( they flow 290cc at 2.55 bar ) and about 309cc at 2.9 bar - the 315cc injectors pink you mention are 315cc at 2.9 bar pressure which is higher than stock pressure.

Yea that's about it,
I think you might be refering to Denso 19550 2150 330's which are rated at 325cc flow at 3bar. This compares to the stock injectors that flow 314.5cc at 3 bar ie 15.5cc more flow over stock injectors if they were both using 3bar fuel pressure.
