I have an RB20Det with a T04E on it making 308 at the wheels. I'm swapping turbos to a GT3071r, and I'm looking to go E85 as well. I'm looking at upgrading to 750cc injectors from my 444, and from my calculations it should put me at under an 85% duty cycle. Just wondering if anyone has any personal experience, and if that is to small of an injector (maybe I should be getting 1000s). Any help would be appreciated.

If it's 400whp range your looking for I would think the 750cc's would be fine.

Yup, shooting for 375/400 at the wheels, thought I had put that in my post. I was thinking they would work as well, just looking for others input. Thanks.
