Revo 2.5R Engine help

[AJrc]

Okay i have a Revo 2.5r. It has the 2.5r in it right now.
I was wondering if the savage 4.6 k will fit in there?
Is it big block?
Do i need a kit to do that?

Yes, you need the big block conversion kit.

The reason why i ask this, is because my 2.5r engine seems to leak alot.
Is this due to too much fuel going in, tuned incorrectly, loose something?
i tightened all the screws?

bad o-ring maybe, highly unlikley too much fuel. you tightened down everything, so else something broke (fuel line?).
