blitz dual sbc with wastegate help!! Boost spike!!


Recommended Posts

Just fitted a td04 kit with external wastegate, when the boost controller is hooked up it will run fine for a while, only running .7 - .9, but I'll put my foot down in 1st or 2nd and the boost controller will just stop working, and the boost goes to way over 1 bar! I'm worried about blowing my engine, anyone got any suggestions why it's doing this? It's wired up like this

I've got the pipe on the top of the wastegate going to out, a pipe from before the throttle body going to in, and the nipple on the side of the wastegate going to the nipple on the turbo. Is this right for a starlet?

The car runs fine with the boost controller disconnected

It is defo set to wastegate, turns out it was a bad earth lol was driving it in the dark and u could see the green glow flickering slightly, started banging the plastic under the steering wheel and it was causing it, turns out the screw for the earth was a little loose lol :-)
