He can make his a GST for less than 1K. What is balance and shafts? Do you mean the balance shafts? Also, Im curious why you wouldnt put 1G rods, and 2G pistons in it, instead of 2G small rods and 1G lower compression pistons? Also, its very simple to make the car run right. Its all bolt on. Whats hard about getting it to run right, specifically? Maybe I can clear that up for you.
