not as electrically smart for the electric pump, but i was debating some cams (254) with it too. i wouldn't go for the itb's but might do a corolla throttle.
will the factory ecu run fine with the increase in compression? i wish there was a way to increase rev limit

You can increase the rev limiter if you overclock the factory ECU, but you have to be careful, too much will give you serious problems. But that is one "ghetto" way of doing it. Of course, a proper piggyback or standalone is a far better route.

Premium will be a must at minimum with that kind of compression and stock timing.
