Switching to E85 and running a s256 Turbo, looking to Max this Turbo out. I will be running a walbro 416 E85 pump but not sure if I should go with the new 1300s or 2000s.. I know the 1300s were made for E85 but will it be enough with the 416 pump.

 

I think the 1300's and walbro will be more than enough to max that turbo.

 

ID1300 at 100% duty will flow 312 LPH (1300 x 4 x 60). Your pump will be maxed out far before the injectors will.

You can see a helpful break down of flow capacities here:

Click your year, EMS, then E85. Different flow ratings will be displayed. You may wish to consider upgrading the pump at a minimum as well to the 320 LPH AEM E85 fuel pump:

That being said, the price between the 1300 and 2000 is fairly minimal:

We keep all these parts in stock.

 

Yeah Jeff Evans recommended that pump and said with E85 would put me in the 500-600 range and I think the S256 will Max out around 550-580 anyway. But just wanted some advice since this is all new to me

 

Op has a walbro 400 not a 255.

 

just buy the 2000cc injectors

Most people with id1000cc injectors max them out on e85 at 450-500whp at stock fuel pressoure.

1300cc injectors are not that much bigger

Your walbro 400 e85 pump is good for over 700whp on e85

 

Hmmm

 

May as well get the bigger injectors. That way if you go bigger on the turbo later its just one less thing you need to change

 

Yeah was thinking that also but will the idle and light throttle be as good as the 1300s? And how will the E85 affect the 2000 long term? I know the 1300 are full stainless steel made to run E85 but also perfect for pump gas.

 

I'd go for the 2000's as well. Let me know we are having a big sale on them now!
