Hey all, I hope this is in the right topic. I've got a 2001 ER34 Skyline. I've got a question regarding External Wastegates. I've got a Garret GT3076R Turbo and a HKS External Wastegate. I'm currently using a Blitz SBC Boost controller and have had no issue until yesterday. I've had a small boost leak for a couple months now as I've needed to get a small piece of intercooler piping made up. I had the piece made up and installed it and immediately noticed that the car was idling better and I had no rev hang anymore so it was a win. The wastegate currently has a 10 pound spring in it. When I took the car for the 1st drive around the block, it was running better than ever. But as soon as I gave it, I boosted straight up to 30psi before the gate started to open. I know when it's opening as I've got a screamer fitted. The only reason the car isn't boosting any higher is because the car is boost cutting and it's splattering like crazy at 30psi. I previously had the boost controller to open the gate at 15 pound, so I turned the controller off and still got 30psi. I opened the engine bay and Disconnected the boost controller and I still am running 30psi. I haven't got a clue what's happened. Everything was fine, and all I did was just change a short pipe over, did not disconnect anything. I currently have the controller hooked back up as I've rules the controller out of being the issue. I have the controller hooked up as follows and it was working perfectly fine for around 3 years with no issue Blitz Dual-DBC Spec R Boost Controller "IN" on the boost controller to a nipple on the J-Pipe going into the throttle body "OUT" going into the top of the Wastegate Bottom of the Wastegate connecting to a 3 way T piece splitter connecting to the Throttle Body I have it connected to the Throttlw Body because the Turbo does not have a Nipple on the Compressor housing. As I said, I never had any issue with this current set up, but if it is incorrect by any means, please let me know. When I Disconnected the Boost Controller and want just Wastegate preasure. I had the Top of the Wastegate connected to the J-Pipe and the bottom of the Wastegate connected to the Throttle Body Thanks again for any help guys

Hey guys, didn't was to start a new thread as it would be excellent to have this information on this one for future and current users. I'm converting my 2001 R34 Gtt Sedan with a 1995 R33 Gtst Gearbox and all parts from that car. I've been given a wiring loom and I know which cables go to the transmission as they are obvious and I have plugged in on one of the photos. I'm not sure about any of the other plugs though, I have yet to pull the dash off and connect the break pedal and clutch pedal. Are all these plugs something I will figure out quite easily when everything is pulled apart or is going in blind a bad idea, do I even need to use half the plugs on the loom? Thanks guys and Happy New Year
