7500rpm rev limit huh? On a stock M54?

Hell, I'm tempted to tell you where the rev limiter map is just to see the results of you running that change, LOL

on B25 you don't need ati super damper, also you can install 272 cams without titanium retainers and valve springs as Schrick AVL specified, finally, read about 323ci with 272 cams build from Sydney!!!

didn't realize it was a 325.. are you sure valve float dosent exist around that rpm? pointless with a 325. better to have a 3.0l to attempt that

I'm fairly certain the valves will float at that RPM. You can do a solid lifter conversion... but does the M54 head even flow well enough to really make good use out of 7500RPM?

I find it funny how people looking to do this stuff never search to find out who has already done it.

up to 7500 RPM you don't need solid conversion kit
to increase head flow porting may be done
