Hi I’m looking for some help with building my engine, I was wondering if anyone could help me with what parts etc.. I have a Honda b18c4 engine that I want to build to 1000bhp, I’m getting Darton sleeves fitted, I want to get wiseco pistons but I don’t know what ratio and what size. I also don’t know what valves and what compression to use. What skunk 2 cams are best to use? What valve springs and retainers? Also what turbo is best to use. I have a s9b box, what bhp could this box handle? Is it any good or shall I get a different box? Do I also have to upgrade the crank or can I keep the standard crank, thanks

I think the Wiseco wristpins are rated up to 500hp. So you might need the upgraded wristpins or choose different pistons.
Lots of connecting rods are rated to a maximum of 900hp, so make sure the connecting rods can handle over 1000hp to be safe. I think you can go with Turbo Tuff or Manley rods, but check the rating on them.
The Darton sleeves are good if installed correctly.
You’ll need race gas such as 116 octane or maybe 110 octane. See what type of fuel is available, and base your fuel system around that.
You’ll need coil-on-plug ignition, because the stock distributor is good to about 600hp.
You’ll need that transmission upgrades to handle 1000hp, which I’m unsure of.

 

^^ This all day.. These threads that come up where the most helpful of helpful folks want to, well, be helpful and just really can't take some of them seriously as they just seem so incredibly outlandish and noobish.. One thinks, "do you even realize WHAT you're asking?!"
Seriously.. Find a builder like, Humble Performance, email them and ask for proper directions and plans.

 

Most everyone here would love to help, but if you are serious about building a 1000whp car you will need professional help unless you are basically a professional in which you would not be here if that was the case
