Have a friend that has a problem.. Needs help. Let me know what you think
95 civic with a jdm gsr motor and a greddy turbo kit. its the 18g turbo with custom 3" d/p and i'm running a hondata s300 with hondata boost controller. i just took it to get dyno tuned but i've got a problem. when we do a pull it starts out good hitting about 7-8 psi from from around 3000 on up until it goes into vtec then the boost starts to rise and it hits 10psi at 7000 and shuts down. it made about 230whp. we tried switching the wastegate vac line between different sources and it didnt change anything. on the last pull we disconnected the wastegate actuator and held it open and it went to around 7500 and made 251whp but it still cut out. i dont know whats going on here. does anyone have and ideas or experience with this kind of thing? my tuner said that maybe the downpipe isnt letting the wastegate open all the way. could there be any other reasons? thanks.....
