on stock cam timing, my powerband starts at about 4.2k and goes alll the way up to redline. let me tell you, these toda cams are awesome...the powerband REALLY kicks in after 4k...10.5mm, 264 duration, on both intake and exhaust.
"TODA Racing offers a variety of camshafts for the Nissan SR20 engine. All camshafts are made from brand new TODA billets, they are not regrinds"
Good stuff. I also have the toda valve springs (custom shims to increase the spring rate) Ferrea stainless valves that were also custom made, tomei bronze valve guides, port and polish, intake mani and exhaust mani were also portmatched, and ported..intake mani was ported but not polished so the fuel can atomize, and rocker arms stoppers, tomei sprockets. my head looks beautiful and performs even better then it looks. i heard that you can use the SOHC cam on your exhaust side for increased power?
