if you want all motor an h23 vtec build is actually really tricky and unreliable if you don't have every thing perfect...... you can easily do an all motor build on the h22 and get amazing power........ one example mahle gold series high compression pistons(only piston that will work with the frm stock sleeves) puts you at 11.5:1 compression ratio.... balance the crank, forged rods..... on to the cams proven cams jun(very pricey), skunk 2 pro(decent price) and crowler cams all have great potential and have a proven name then you can always do a mild build and go the jdm type s cams which will work with the stock valve springs and valves and have a more aggressive lobe.....then we move on to the header you can go proven RMF only true 4 to 1 header very pricey but proven..... stay away from dc sports the quality has droped due to new ownership if i am not mistaken they are now owned by pilot automotive who outsources them to china...it is all how you want to do it ..... now if you want to go boost and not resleeve the block be careful i have heard mixed opinions on the stock sleeves holding to boost.... but they do have a mahle gold series low compression pistons keep in mind do it right the first time and
