Hey,  Im going to rebuild my topend while im installing new turbo.  Anyone recommend bigger valves? My heads are not from a TGP, they're from a 2.8.   Where can i get turbo 3.1 valve springs?? Also need 94-95 3100 rocker setup.  My chip is stock but im going to upgrade after this.  Thanks for any advice.

The 2.8 heads should have the same sized valves already. There is hardly ANY room for a valve upgrade on our heads.  Turbo 3.1 valve springs should be identical the NA versions as well, we use the same exact camshaft. I would upgrade to the LS1/LS6 stock valve springs if you're going to replace the springs though.

This topic should have all the info you need for a spring swap. Use those part numbers and search around google, there are a lot of places that stock the LSX springs for cheap.

Mfewtrail, thanks a lot for the head info... another question for you guys-   Is the TGP turbo the same as a T25 from a Eclipse or Talon?  I need to know if all T25s have the same bolt pattern for the crossover and downpipe.  Im looking at rebuilt T25s and dont want to get the wrong one.  THanks
