500 Vinson 2002 Arctic Cat TBX 500 Question On Engine Change?

2002 Arctic Cat TBX 500 question on engine change? - 500 vinson

I bought a 2002 Arctic Cat TBX 500 at eBay, which lacks a variety of engine parts. I think it would be easier, just replace the engine. I think that fit a Suzuki Vinson 500 also, but not 100% positive. Who knows in what form and I use a 500-Suzuki Motor Quadmaster manual? Please help!
