We have built many of these iconic 90’s sportscars including an elusive ’99 VR4 and our own ’91 with a fully built 6G74 3.5L engine in it!  We are currently working on developing a CNC program for the heads as well as some custom pistons which will have ceramic dome coating as well as protective skirt coating.  We offer the “head lift” fix as well for those looking to run higher boost/HP numbers.
