ok so here is the deal... i used to have a greddy kit on my GSR that i sold and now i wanna put it on my stock LS but the wastegate actuator diaphram took a **** and leaks ... so i need to get a replacement wastegate... i need to kno what car has a wastegate actuator that would allow me to boost between 9-11lbs without the use of a boost controller.. and i seen some go for 70-80 dollors but i really dont have that much to spend and am hoping i can get one off of a car and weld it on the same bracket ... i have seen it done before but i need to know wat wastegate allows only 9-11 psi stock

Thanks and help is much appriciated
