To me it's not about what is trending and what not. I want the best solution for me.
The rapid growth of V8's in drifting makes perfect sense and it's all down to the driver though. If you're used to me to drive with less power and work hard, you'll drive hard again with another engine. If you're used to big power right away, you'll just rely on power and not getting everything out of the car as possible.
I won't change my drivingstyle after an engine swap
I think it would be amazing if I can keep driving like this, just with more power. Able to initiate harder, to keep up with the bigger guys etc...
2JZ is great either but not sure if I'm going to like the turbo lag. Turbo also brings more complexity to the build. So chances are big that I'll go with the V8. Also partswise. BMW V8's, gearboxes are so much more available over here than the Japanese stuff.
I'm just searching all the parts now and see what is easiest/best. For now it's the V8.
