haha very much going to pass on that have no idea but my flatmate doesnt know to much about subies so all that mattered was the autos part haha and then it started
VF24
STi ver 4, June 1997
Common for Group N rally cars and has good bottom end. Not recommended for stroker engines or
engines with high boost as turbo is small and can over speed.
Same compressor housing and wheel as a VF23 with smaller Turbine housing (18)
Best turbo for Auto’s and cars that want the best bottom end and least lag.
in saying that looking at some spec threads they rekon they are only good for 17psi mine runs 17-19psi depending on temps just fine guessing they just safe parameters
