stock fuel pump wont hold up. make sure you have an inline or upgraded in-tank.

cam timing IS an issue.

the turbine wheel shouldnt be an issue... it MAY become one near 7000 rpm as the .63A/R housing is still a bit too small for the H22, but a .82 A/R housing is too big, resulting in LONG spool up times. your best (and cheapest) option is to have the turbine fins clipped. should only cost you $100 or so from a local turbo rebuilder. if you dont have a turbo builder, i can have my builder do the clipping for you, and i can get you his info if you want it. BUT, this is not causing your current problem.

Unless you've got a new fuel pump, i'm gonna have to call it a fuel problem. the BTM you're using to control timing may also not be responding correctly, so double check it. also, read your spark plugs. it may also be a check valve defect, or even your turbo compressor side is improperly sized, so you're not flowing enough total air at pressure. (boost is not just about pressure, but also volume of air in CFM).

is the power plateauing at the VTEC crossover, or is it severely dropping off? EGT's would also be helpful in determining this problem, along with a list of all turbo and turbo related components in use.

just best describe your loss of power in the next post.


LASTLY.... your oil pressure is too high for the turbo. the motor needs 40-60psi for VTEC operation, but you need to step down the line pressure feeding the turbo. turbochargers need no more than 30psi oil feed or it will blow oil past the turbine seals (oil rings), inducing oil loss, coke, smoke, and premature failure.
