Im planning on doing a swap on my teggy and after A LOT of research I decided to go with the K series but cant decide if k20a k20a2 k24a2 or a k20/k24 frank. I know k20 gives me more revs and k24 more torque, more torque sounds good but I dont know whats best for my plans. Money its no a problem and Im going all motor no turbo. I dont know yet if im upgrading cams pistons rods ect... but there is a big chace.
SO in your opinion whats my best option?

 

And which tranny will be best with that engine

 

if you want to go all motor I suggest a k24 with a k20a, k20a2, or k20z1 head on it. I cant remember but I think ive read the k24a4 is a good candidate for this build. And also if you build the block with new internals and have a shop blue print it all and balance it extremely well then you could still turn a lot of rpms with that engine. either way use a k20a2 oil pump if you do a frankenstien.
