Ive heard great things about Drag Cartel. They make a ton of different versions from only slighly better than stock to crazy high RPM power. Just hit them up and ask they recommend for the power you are looking for.
Cams will only give you a little more power. A good header will make 3x more power on a 2.0. They (Stage 2's) were my last mod, and wouldn't get more than about 5whp/6wtq, no matter how much timing was pushed on the dyno.
My ASP 4-1 header...+20whp & +10wtq on the 1st pull.
Only by going to a built K24 block, w/a higher compression ratio, will you see worth while gains...and run Stage 3 or 4 cams.
Around 280whp & 220wtq depending on dyno, engine, and octane fuel.
(Seen 320whp on E85...and more, with race fuel, head porting, larger valves, etc...)
I'd also highly recommend a sleeved block, with forged internals, because pistons wandering around at 8000rpm is why so many engines blow up. Especially with a longer stroke.
This is the expensive way, but safer, and built for reliability and longevity.
Go to K Mod or a company that can build it, or just sell the parts, like just a CRV K24 block.
