38mm tial wastegate ? HELP!!!
i just picked up a 38mm tial wastegate and was told it had a 8lbs spring. took it apart and found a red spring witch is a 5.802lbs acorrding to the web site. this is my first time messing with turbo so it my first time dealing with a wastegate.
1.my first question is the small spring the one that sits up higher in the wastegate and the larger spring sits in the grove that is lower that goes around?
2. next the base of the wastegate is it supose to spin aroud freely because either way i spin it it dosent losen or tighten up im talking about the part that is connected to the flange.
hopefully someone can help me and any info is appreciated very much. thanx drew

Having a little bit of difficulty understanding your question.
SMALL red = 5.8 PSI, however BIG red = 11.6. The way you tell small/big is the OD of the spring. http://www.tialsport.com/docum...p.pdf
It sounds like you have 2 springs in the wastegate, you need to find out what colors/OD they are and the total wastegate PSI is the sum of those 2 springs.
If you are talking about the "cone shaped" piece (diaphragm/spring cup),then it is normal for that to spin freely.
But if you are talking about the base housing, that shouldn't be moving. If it is, you need to take off the diaphragm and tighten the locking nut under it.

Glad you were able to fix the problem. Was it just a loose locking nut? Also make sure to re-check your spring pressures.
