no boost controller as of yet, but I will be adding one soon
Did you still run your coolant lines from the upper radiator hose to the turbos? Or did you run them souly on the oil feed lines?
How many o2' ports does the gte have? We have like 3 right? How many ports will we have to create on the dp or w/e?
I ran mine on the oil lines alone.
As for the wastegates, from what I understand that is one of the TTC mod methods that the supra guys use. I got it on MKIV.com As for overboost, I believe a boost controller will remedy that....again correct me if I am wrong guys. Cuz if I am, I'm gonna have a GREAT time pulling that motor again...:jawDrop:
Wiring the waste gate flappers open will not cause the turbos to spin faster to reach the same boost levels. It will just take them much much longer to reach their operational rpm. Now if there was a giant intake leak that would cause the turbos to spin a lot faster to make the same boost level.. . . Wiring the gates open will cause the turbos to spin to ungodly speeds to reach desired boost levels instead of spooling up to the desired boost and letting the gates relieve exhaust pressure to control boost pressure.
Yeah, that was a my bad. I was on Mars somewhere yesterday and was thinking back asswards. I was standing in the garage last night going "uh der."Wiring the waste gate flappers open will not cause the turbos to spin faster to reach the same boost levels.

Let's try to clear up some things...
The stock turbos are plumbed for both water and oil.
The stock turbos have internal waste gates.
The peripheral flaps are NOT waste gates. They are control flaps to regulate the sequential operation of the twins...but without the stock ECU managing the VSVs, they are irrelevant and become restrictions. I cut out my EGCV with a plasma cutter, as well as every other control valve for a true twin conversion.
It's handy to have a welder though to fill in the holes left by the missing actuator rods.
Ahh.. Just for clarification, there is one wastegate that controls both turbos. The rear actuator is not a wastegate but a prespool controller.I am aware of all of that and have done the same things you have to go TTC. My original question was to see how anyone who has done this swap (and kept the stock twins) how they plumbed the stock wastegate actuators being that they both have 2 ports. I was just curious if you guys used a rubber vacuum plug for the 2nd ports and if so how have they held up in the underhood heat. Or have you done what I did in my second picture and t-eed off to plug into both ports. Sorry this thread got so confusing over what I thought would be a simple to answer question.
