adjust boost/psi on internal wastegate???
 

I just recieved my dsm t25 turbo, and want to know how to adjust the boost on the internal wastegate. It seems sealed, so i can't replace the spring (without breaking it)... and I heard eclipses run 8-10 psi stock, and Im looking to run 6.

any ideas???

take it off and run the o'g. spring for a wastegate, pull it further for more boost, put it closer to lower boost. boost controler and lower boost at the pull of a spring.

Internal gates are not like externals you can't replace/change springs/diaphram...there is 2 ways well 3 or 4...you can get a actuator that is for a hight boost level, run a boost controoler or modify yours, cut in half and thread both ends and one of those long nust so you can make the rod longer or shorter...or just buy a adjustable actuator

just stumbled (literally, wasnt even looking for it) across this online: think it'll work?

sorry, "o'g spring" ??? Im not sure what that is.

also, with the cut arm method (see diagram) does that just compress the actuator more, or does it open the wastgate a lil to relieve pressure. I dont know if I want a leaking wastegate all the time.

you cant lower the boost with a boost controller.....and the OG spring is just a spring that holds the wg flapper shut. it works, but not well. and yes, cutting and threading will leave the wg open a bit (depending on how you set it up)

oh i just saw he said he wanted to run less boost, yea BC won't do less...if you re mount the acctuator you shold be able to have the flapper stay shut, right?

dude, you want lower psi? run the stock wg and a huge ass ic, you get a slight pressure drop in the ic thus running less boost haha

You could get a new exhaust flange on ebay, that will remove the factory wastegate controller and wastegate, then get an external wastegate and weld it to your manifold...done.
