what would be the better choice wiseco pistons with a little higher compression ratio or comp s1
The factory compression ration is 10:1 which is the highest off the shelf CR Weisco offers for the L61. Also any aftermarket cams for the L61 are going to require better valvesprings and having the PCM tuned.
If your staying without boost go with the comp cams, we carry them on our site.
