Found these, read here that the genesis had the same injectors. Was wondering if there was a "too much" when I came to injector size.

Would there be a benefit with going to these 750s over the 550s? (supposing they fit). The price is similar, and if your going to tune anyway, why not have more available fuel?

Not on an OE ECU, or without a return system.

 

+1, also no need for something that big unless you're doing a "Monster" build (400+) or a 275+ build on e-85.

 

When "huge" injectors are scaled down too far, the idle tends to be pretty bad...
Frankly I am amazed that 550's run as well as they do in a mini.

 

I have 1000 cc injectors on my MINI with a Vi-Pec ECU - idles just fine.

 

All depends on who scales the tables in the ECU, and if that ECU and fuel system is even capable of running them... Stock Bosch Siemens cant really go bigger than the 550's without a trade off of issues.
