sweet what hp do they have i tried the search and went on google couldnt find any thing

Its more the torque advantage a 5k has. Remember torque is what accelerates you :D

so 5k has a fair bit more torque yeah what bore and stroke is 5k compared to 4k??

same stroke as a 4k(73mm) but the bore is 80.5 mm, 5.5 mm bigger.

They use the same crank as the 4k, just a bigger bore and stronger block.

Depends on what engine you get, there are a couple of types, one has dished pistons and the other has flat tops, and if you are really lucky you may find one that has solid lifters as well.

The flat top engine will benefit from a 4k head, with the extra compression.

what about the ports in the 4k head are they smaller?

no,4k and 5k have the same ports. 4k-u(dished piston) and 5k(dished piston) have the same head, 27mm intake ports.. and same valves also...
