RPM increase aft change to manual transmission
on an auto at the speed of 100KM/H the RPM used to be at 2000.
now after change to manual transmission, the RPM is at 3000 for 100KM/H. Is this normal ?

Didn't mention what gear. If that is MT 3rd gear, that sounds right. Can't speak for the AT RPM.
Not many transmission swaps that I have seen, gratz, and we would be interested in more details

Car specifications:
Greddy Turbo Kit
Microtech LT10s
When using 6AT
No RPM cut
Speed cut at 180kmh (throttle off)
Boost kicks in in 2500rpm
Rpm between the 2000rpm to 3000rpm when at about 100kmh to 120kmh
After swapped to 6MT
RPM cuts at 9000rpm
No speed cut
Rattling noise heard from gearbox/clutch when above 5000rpm
Turbo can be heard spooling, blowoff also heard, however no turbo "pull" felt when driving. (as compared to driving 6AT)
Defi boost guage indicates very low (0.1 to 0.3 bar) boost
when in 6th Gear, travelling at about 106kmh, RPM is about 3300
Sometimes when in the 6th gear, car suddenly loses power and starts to vibrate rather violently when taking foot of the pedal. Funny noises heard from gearbox/clutch area. This is done when RPM is at 3k+ rpm. However when stepping the pedal again, vibration & sound is gone, but car feels very underpowered.
i am still using the same dashboard display (0 to 9000rpm) however have plans to install aftermarket tachometer.
is this just a case of the need to re-tune the car after AT to MT swap? or is the gearbox fucked?
Please help.

Perfectly normal. In fact, should be about 95 or 96km/h at 3000 in 6th gear on a stock gearbox assuming gearbox is from a pre-facelifted model with no change in final drive ratio.
