The SR injectors drop right into the DE side feed fuel rail. They are good for close to 240whp. You can usually pick up a set for ~$100, but its best to replace the O rings and have them cleaned and flow tested.
http://www.Deastchwerks.com can do this for you for $15/injector I think. They also sell new 370cc injectors for $229/set.
BTW, the VG30DETT also uses 370cc injectors. The 95-96 ones will fit the KA rail. The SR, KA, and VG injectors ar all high impedence...
