I was looking at 870cc injectors, I notice that there are different spray patterns, impedence etc...
If you have a recommendation please advise exact part number so I know what to look for.

What is known to work well in YB's, I am looking at setup including GT30R, BD16, mild port work, RS500 intercooler ...

I am assuming I will need an aftermarket ecu to map all of this as no one in Aus does webber marellis...

Any help much appreciated..
