I have 2 front guards off a R33 gtst, Not really sure what they are worth. Both have a slight tear at the front where the front bumper bolts on but it is nothing major. I'll put them up for $80 each or $150 for both.
Turbosmart Type 2 Blow Off Valve, blue base with adjustable gold top, comes with R33 adaptor. $80 including postage. Also I think it is a M-Spec front bar not sure, Needs a little repair on bottom from steep driveway. $150 I will put pictures up in the next couple hours of all parts.
