View Full Version : s13 sr20det(t28), possible wg actuator issue?

hey quick question, about a week ago i switched to a hotpipe with a nipple so the wg actuator could have its own boost source and to also fix a spiking issue i was having between gears. after i did that the turbo was still quick to spool but a few days ago the turbo started to become kinda laggy so i boost leaked tested the system and fixed all of the leaks and its still doing the same thing. i was wondering if it could be the actuator going bad. i had this issue before when i had the greddy hotpipe on with a nipple as well but when i swapped back to having the wg line tee'd off of the bov line it became responsive again. im wondering if anyone had any suggestions before i pulled the trigger on buying a new actuator.

bump anyone?

Why not test the actuator? Your already in there testing the whole system for pressure, might as well apply pressure to the actuator and see if its leaking.

Running a boost controller? Could also be the culprit.

i replaced the actuator with a new oem one and it seems a lil better. its did the same thing with 2 different boost controllers. i had an evcs before it crapped out and replaced it with a blitz sbc for the time being. i have the gain set on 36 iirc and it feels somewhat decent for the moment.
