Well I'm nowhere compared to Stevo-o but I'm also considering swapping to E85.
Currently my 32 GTS-t runs a quite stock RB20, and hopefully some E85 could liven the old girl up.
I'm running the standard in tank pump, with a 3 odd litre swirl tank and a Bosch 010 pump feeding GTR injectors.
I've been told I'll need a new in tank lift pump to cope with E85 as the standard one will get eaten by it (how will the factory steel tank cope?), and I'm wondering if the 850cc injectors I have will cope flow wise?
