It does have BSTs. The motor has JE 13.5 pistons, G1 kit intake cam, and kit spec head porting clean-up. It used to have a full Akra Ti system on it but I have removed it since it's basically irreplaceable at this point and not worth sacrificing to the track gods. I'm on the lookout for a similar, full system.Wow! That has to take the cake as the trickest Gen 1 so far. Beautiful! All you need now are some BST carbon fiber rims! What have you done for added horsepower? Or is the motor stock? Great job!
