Cory Maurer, I am very excited to see your results, please post em up when you get em!! I have the exact same fuel set-up as you. thinking about making the E85 switch..

 

I working on boosting my s2k but I know you need a lot of fuel pressure when on e85 and a small pump.

My Civic set up had a intank and in-line 255 Walbro and about 80psi base fuel pressure with FIC 990cc's; I made 609-629hp before my fuel system was totally maxed out.

I plan on using the same fuel system on my s2k.

 

I made 610whp and 439tq on E85 using ID1000's at 100psi base pressure. At 8400 rpms we were at 100% duty cycle. This is with (1) Walbro and (1) Bosch inline pump.

Both pumps re-wired and relayed
