Are HKS injectors any good or cheap for a reason?

we do our own Bosch cores as a direct fit or the likes of ID's

Are Bosch good on tick over,low rpm's?
should i go with 740cc or 800cc for 440-480 horses?
am i need FPR if i have got lph340 fuel pump fitted?

you will struggle to get good quality cores lower than 1000cc these days mainly because the idle, etc that used to be an issue with large injectors simply isn't a problem these days, even ID no longer offer anything smaller than their ID1050 range
BUT there are still many poor quality injector sets not to mention the multiple 'copies'.........

and just to upturn our post above we have just finalised testing of a direct fit Bosch top-feed core which at a fairly std 3BAR fuel pressure equates to 725cc........

so as of now then yes there are high quality options from 725cc to 1000cc and beyond
