I have just heavily modded my evo 5 with 8 motor. Am just about to dyno it again. They want me to run e85 but I dont have regular access to e85 or 98 octane as I live rural so was going to tune it on pump gas, 95. I was going to twin map it and have one setting for e85 and one for 95 octane. Im a bit concerned as the only fuel system upgrade I have done is a bigger walbro fuel pump with constant voltage/relayed and 1000cc injectors. Was wondering if all lines and tank would need upgraded to handle e85? Was wondering about possibilities of a meth kit/aqua mist and cost in nz $$. Any ideas on these concerns would be appreciated
