New Toys for the Si
by VitViper on Oct.20, 2009, under Cars, Si
Just got most of the new toys for the Si in the mail today. Our friends from UPS and Fedex made quite the delivery today. So here we go.
First, the Unorthodox Racing crank and alternator pullies.
Second, a much nicer header to replace my DC Sports RH that’s broken two flex pipes until I finally welded a 2.25″ collector and flex pipe in. This new header is absolutely beautiful. Beautiful bends and welds. But it’s a pain to assemble, so I’ll just let the shop do it… The primaries are beautiful.
And now the biggest money maker. Go-Pwr KSi cams provided courtesy of Go-Pwr. These things are beautiful. Comes with a complete valvetrain setup: springs, retainers, seals. The works. The cams are actually ground by Webcam Shafts. Specs on these cams?
Intake:
- High-cam (VTEC) lobe: 272* duration @ 1mm & .538″ lift.

And of course the photos!
