hello, new member on this site. Any idea what kind of boost level an original vr4 6a13tt is running on?
I'm going for more hp on my 6a13, changing all pipes, new iintercooler and putting in apexi boostcontroller,how high can i go with original pistons? 1bar maybe 1,2? And why has the vr4 boost cutoff already at 4-5000rpm? Thanks /ubbthreads/images/graemlins/smile.gif
