what injectors would be the best to use with a bmw m52 turbo

its a m52 based , custom turbo ...


high imp or low ??


are there any that are much better than others .....



thanks for any help

Depends on how much fuel you need

card counter's right, what size you need will depend on how much horsepower you're making. That said, stick to Bosch/Siemens injectors. They are the highest quality injectors. They have the best spray pattern, will be the most consistant and the closest to OEM quality you will find.

well , I think I know about what sizes to use ....


I have some 42 lb ford green tops that i plan to start up with, so I should be fine but for how long ...

will I run into trouble with a pt 6776 turbo ( before i can change injectors)

but thanks for the tips about bosch/ siemens !! ! pretty much what I was looking for ....


How are Precision injectors ? quality? spray pattern ?

thanks guys

I don't know much about Precision injectors. See if you can find out who makes them (I'm pretty sure they're just rebranded injectors). Just stay away from Lucas and Rochestor injectors. They seem to be pretty common because they're available in rather large sizes. They don't have very good low pulse response and the spray pattern is usually fairly poor. At higher flow rates, the pattern is less important so they work fine for drag racers. RC Engineering also sells a lot of these. Not all of their injectors are Lucas or Rochestor though, so if you know what you're getting you can Bosch/Siemens injectors from them.
