My evo 6 motor threw a rod leaving a nice hole in the block at cylinder #3. I've sourced a fresh evo 4 engine block to build my new motor on, was looking for suggestions regarding my part choices. The car will be used as a daily driver and road racing. Expecting to push ~500 whp on 91 + meth with a fp black. Want to rev high 9isssh. This is my first build and I'm not sure if I chose the right parts for my application, gurus chime in please.

500 hp and all those mods?

People rock 500hp on stock block with a good torque controlled tune and revved out to 9, that would be easy.

Ive been doing a lot of research since I'm in the same boat as having to select new parts for a build...


The internals that you selected could handle probably 800+ HP. Which is great but unless you plan in another year or so to really push the limit and tune to that much power, you may want to kick it down a notch.


Lighter H tuff rods will be easier on bearings than I beams (standard H beams can handle 500tq but that is their max). H tuff should be 600+tq. Hp is not as hard on internals as torque and HP is the result of torque.


Non HD pistons may suit you better since they dont have the thermal changes of the HD counterpart that can beat on cylinder walls on cold start.


If you want to rev to 9k then need balance shaft delete (hopefully a more dedicated race car than street and not really a daily).

500hp, standard studs would be fine...

GSC springs, everyone seems to love them.

OEM 9 belt supposedly has kevlar in it and is stronger.

MAPerformamce says that they've seen better wear from king bearings vs ACL.

Honestly my best advice would be to call up Maperformance and talk to them. They were a huge help and amazing to talk things through with. I talked to Leo but Adam is one of their most experienced 4g63 people. They can also source all the above with great and competitive pricing.
