Mate is that a wish list in your sig? If that's what your running and your only going 100 YOU HAVE BUG PROBLEMS!!!

Take the car to a dyno and get it checked out

 

its not so much what you have done. its how well it was put together and and tuning is the key!! pm me or call the shop if you need help getting your car faster. it sounds to me that you just need a little help, and you should be fine. that setup should get you well into the 110mph range or more depending on the weight of the car and slicks your are using. etc.

 

Does your car cutoff at 100 or you're just not making power? JDM computers have a top speed cutout as per gov't regulations. Are you running a JDM computer?
