I wonder if my turbos will fit with the pentroof without hacking the frame of my car. My compressor housing diameter is about 160 mm . I believe stock is 140mm. I am going to wait and see by end of July if Chip or Greg will get their manifolds done. I might have my split downpipes w/external wastegates forsale . They will bolt up to any 5 bolt flange turbos like the HKS.
