Thanks a lot guys, it looks like I'm getting somewhere...
cheap! Looking in the lists, fuel delivery of the 24v injectors (for an advertised 230hp) is the same as for the 12v engine ones (up to 200hp) This means that I can use the Motronic 12v injectors in the project engine, where I'm expecting
somewhat more than 230hp. However,if we go by BSFC numbers, it turns out the 24v needs ~220-225cc injectors;
how does it manage with 190cc ones

Unless the lists are wrong (and they differ between them)it doesn't make sense
