The TT 120RP has a built in pump, so you don't need a perry.
I have the same engine in my Leo on a home made pipe.
Decent power, i'd say.
You will need a header and a pipe.
Where to find'em i don't know. A few years back they were listed on the TT website, but i can not find them now.

some notes:
The prop size you choose is wrong for the engine.
You will need a 16*8 or a 15*10 APC, albeit the landing gear might be slightly short for the 16*8
