So I have 3 k series motors
-k20a2 short block (crower rods, toda pistons ~12.5:1)
-04 k24a2 complete swap
-07 k20z3 long block w/ bad bottom end( destroyed crank keyway)

mated to 04 type s trans w/ wavetrac lsd stock FD

so I have the k20z3 head with rbc that I could throw onto the k20a2, does the oil pump, water pump, timing components all swap over?
or could I throw it on the k24a2 and would the k20z3 head produce more power?


I guess what i'm asking (if possible) is the best combination of these 3 motors into 1 motor. What is the most potent setup? thanks.

It all depends how much power you want and what you are going to use it for and in what car.

-k20a2 short block (crower rods, toda pistons ~12.5:1) will give you the power but less torque than a k24 block even if its stock if you mate it to a z3 vtec head.

I would imagine you would get something like the following.

k24a2 stock = 210-220 whp & 180 wtq
k20a2 12.5:1 cr + k20z3 head = 220-230 whp & 170-180 wtq

It all depends on tune and bolt on's you have. Each set up is going to act different to the bolt ons, so what ever you have choose wiselly.

Look at the whole combination and what you are going to use it for.
