Im assuming that its a 4valve per cylinder engine just like all the other sr20s... I read that u were sayin something about running on just the high lobe?? My impression (havent seen a sr20vet yet) was that the rocker arm is locked into place via oil pressures or electrically to ride the hi cam... which means that ur low lobe isnt connected.. the hi lobe moves 2 intake valves to let air in.. having the smaller lobes runnin wouldnt work because they move the same 2 valves... plus once runnin on the hi cam the small lobes wouldnt b able to touch the rocker arm regardless. What turbo r u thinkin of using?? I was goin to run a GT30R turbo on my last NORMAL sr20 and that wouldve made plenty boost well before 7k... I havent had much tuning experiance but turbo selections and engine buildings i do pretty much every @ work and at home... stock cam profiles r kinda nice too lol
