There is no downside with the 720's... except for when you are at full throttle it will spray more fuel... but that lets you boost higher which equals more HP. 720cc's will be able to push at least 600 RWHP (thats like 800 crank HP...500 more than stock) on a properly tuned 300ZX. RC makes both 555 and 720cc injectors for the Z and they are both the exact same price. JWT will program your ecu for either 555's or 720's for the same price. SGP, DSP, Coz, and a whole bunch of other companies who do business here can get you them... they're about $1000 for a set of 6 injectors. Now as far as turbos... T28's all the way. If you want to ball bearing T28's then you'll have to wait a while longer. DSP makes great turbos that a lot of people here are using with zero problems... great prices too... $1800 for the pair and that's with a 1 year warrenty. You could email Gyro at GyroDSP@yahoo.com and have him sell you the turbos...I bet he can sell you the injectors as well. 720cc injectors and T28's will give you a very fast Z and you'll be eating up Viper's, Corvette's, and just about anything you'll run up against.
