FMA08ISF

I did test drive an IS350 F-Sport and I really liked its LFA display. While I was driving it, my mind was like if I were to buy this car I'd have to remove its 300hp engine and install my 08 IS F engine (2UR-GSE).

We all wish it had a V-8 instead of a V-6

You're right, the engine is the major disappointment in the 3IS. Porting an old engine, no matter how reliable it is, into such a new model is a horrible mistake IMO.

Just get the f when it comes out if you want a v8.

Another concern I would add is the engine doesn't make a great noise. And there's no exhaust note!
