A friend sent me this spring through the post, he not sure and so am I but he claims it came with his Tial 38mm wastegate and its meant to be for 1 bar. Its about 10.5cm in height and 5.7cm in diameter. Could anyone verfiy if this is a 1 bar spring and will it fit a 38mm wastegate?

tial paints the springs so you know what they are rated for. without the paint on the spring it would be hard to say because they all look the same.

the only way you will find out is to install it and run it and pray it doesn't blow your **** up.
