Have any of you guys done the Greddy T517Z turbo kit on the Si ? If so, how long has the engine been running, what boost level ? Any concerns with engine life ? What kind of number can i be expecting with the kit, and intercooler assembly?

 

i've seen people making 230-250 hp with the greddy kit on rsx's so somewhere around there with the k20a3 motor @ about 7-10 psi. Engine life depends how well you take care of it, keeping it at low boost will be less strain on the motor, plus good tuning and maintenence.
