1.4 BAR on ceramics

[cidaco]

Hi,

I have a GTR R32 rb26dett. one of the turbos with steel internals (we had to change it to steel after a failure fitting custom down pipes). I wasn?t worried about having the car running 1.2 BAR here (12,000 feet /3800 meters above sea level ), but now I?m going to sea level to race it, and was wondering if it is a good idea to place an M7 nozzle (7gallons/hour) instead of an M5 nozzle (5gallons/hour) since I?m going to put 1.4 BAR and 97 octane gas. I?m planning to run 50/50 water/alcohol mix. What do you think?
Would this pressure cause any troubles?

I have a AFC neo to cheat the ECU a little bit in case I?m runing out of gas with that pressure.
Any help will be highly appreciated.

Cheers,

Cid
