I have to change the spring in a TiAL WG. Got a bag full of precision PW39 springs, 2x all 5 sizes. Just wondering if the springs are interchangeable from the PW39 to TiAL WG38.

I have a few TiAL springs too but none are the right size and I'd rather not bother to look for one.
Anyone tried it? Seems like it should work, the only thing I could think of is that the boost could be a bit off +/- 1-2psi which is not a big issue.

 

IDK if this helps but ive use turbosmart wg springs in my tial wg and worked out ok

 

Do the Precision springs have a similar height and width to the TiAL ones?

If yes, in the end it's just a spring. Pop it in and have fun.

 

The bigger ones that I want to use have a similar width to the TiAL ones but the're taller. I'm gonna try it and see what happens.

 

You may run into two issues with them being taller.

1) It will probably result in a higher spring pressure.

2) The spring may bottom out before the gate is all the way open.

Never know till you try though.
