Even at 5 or 6 PSI, I'm still a little concerned that the compression is too high and it may not be safe.. Are the knock sensors good enough to prevent problems?
What impact does the direct injection have on all of this?
A bump from 200 at the crank to 250 or 275 at the crank sure would be nice! It doesn't have to cost $5k to do it either. I bet a decent kit could be put together for $2k or less.
I doubt that an intercooler would be required either.. sure it would help, but you wouldn't need a massive front mount like people run on their Supra's and other aftermarket kits.
Does the BRZ/FRS use a MAF sensor or MAP? If MAF, you'd have to recirc the blowoff valve.. .though at only 5 or 6 psi it might not be a huge deal anyway.
How about tuning? Would you use something simple like SAFC to fool the system or actually get a full tuned ECU chip or something.. that would expensive!!
