Tuned by neptune-
My question is with the skunk2 pro2's should I swap out the oem timing belt? The timing belt was recently changed??
Compression should fall around 12.2 or so-
DSM 450cc Injectors

 

oem timing belt is fine thats what ill be running on my pro2's. what block is this in ? and were did you get a 2.5 world sport exhaust ?

 

The block and head are gsr- I thaught it was 2.5" but maybe it is 60mm or 2.4".... I bought the car with this exhaust so I'm not sure- Why do you ask?
