Ahh, that can change things a bit. Did it test out to 85% ethanol?
Have a read below, your injectors may be larger in relation to a lower Ethanol content as is usually found in eflex Jamo.
Shit hurts my head to think about sometimes!
Running custom mixes
If you're running a mix (say 75% E85 and 25% gasoline), then you have to do a little more work. As an example, let's assume you're running 75% E85 and 25% gasoline. The new gas ratio in this case would be:
0.75 * 0.670 + 0.25 * 1 = 0.7525
With that new ratio calculated, you can calculate your effective injector flow rate the same as above (assuming 850 cc/min injectors again).
850 * 0.7525 = 640
So instead of 570 cc/min that results from 100% E85, your injectors will actually flow like 640 cc/min injectors with a 75% E85/25% gas mix. You can then calculate the global fuel same as always.

Yea no 98 in mine Jamo still have an old E6X computer running it so no flex sensor.
I have a bosch 044 an standard reg, I'm not real sure on pressure.
I'm using united E85 now.
I would definitely go bigger from the get go if I was starting again, would love too see what my little turbo would do if the fuel could keep up

I'm currently doing the switch to e85 myself. Picked up some Bosch 2200's for cheap and about to install the 3/8 lines, flex hose, I'm aiming for approx 280-310kw.
From what you guys have said, Go Walbro 416 for quiet running and direct fit.
A few questions, What is a recommended FPR for me to get? Will an Evo 7 ecu take a flexi sensor input? Is there anything else i should consider doing whilst the conversion to e85?

Keep the std fuel lines they will be fine for well over 400kw on the 416. Just get a turbosmart reg. You can get a frequency to 5v input convertor to run the flex sensor on the e7 ecu from memory. Do a fuel filter and then another after 1000kms.

You can apparently use the std fpr. If its too small at idle, you can redrill it bigger.
but if you using late ecu, utilize the dual speed pump feature. It runs through a resister box, similar to the fan resistor.
im going to run a pwm module on the low speed setting to get rid of stupid resistor. Will be adjustable pump speed then too. If i was real smart, with the pwm module, and a fuel pressure sender, i could run a returnless system
