You need springs also for 9200 I think. like Supertechs or other.

I have heard from people in the know that issues start showing up in the design of the pump when you get over 8850 or so. These motors don't appear to be real happy up there either.
I have my flame suit on because here comes the "I have been spinning 9XXX RPM since YYYY and my motor is fine" posts. I hear from a lots of people spending lots of money to go just a little bit faster.
I have elected to set my personal rev limiter to 8300. I roll back the throttle a little when the dash shows about 71-72 to stay off the rev limiter.

I have enough 8800 . the question is whether to turn the engine without additional mod. such as:camshafts and fuel pressure regulator.

U will need a Fuel press reg, an AFR guage to monitor things, A good external Intercooler,a prop tuned for those RPMs, a good aftermarket intake grate, a 4" air intake system (front, or rear air).
Cam is optional
Throttle body bored out, and aftermarket exhaust are too.
You could also get the head ported & polished

we don't know what reg you have now
and we don't know if your map is set up for a rrfpr
I have been way past 9000 on my stock stuff
I can tell you that your 145 will not like those rpms unless on glass
IMO there is a big difference between 88 and 92

The VTech logger is a wideband controller and will data log your ski. You will need a wideband sensor (about $80) and an Andriod phone to get it to log data. The logger goes for a little under $500 in Jerry's store.
