Questions for honda 97 accord, h22a engine

i have some more questions about main stuff.
q1: whats the difference between drilled and slotted brakes?(maybe i should just get both. like drilled+slotted)
q2: whats a electronic fuel pump pressure control?
q3: whats in the vavle train?(like everything!)
q4: is it worth it to bore a h22a?

 

gte both drilled and slotted and yea its worth boreing but you have got to resleeve a h series to do that you might as well stroke it to . 2.6 litter

 

so whats it do- boreing. and i plan to resleeve it and also im getting new stroket kit

 

boreing resurfaces the cyclender walls but it will also make it to were you got to get bigger pistons./it makes the sleve bigger just buy a good stroker kit

 

boring takes the material off of the cylinder walls making it possible to get larger pistons in there so that you up your displacement. but dont waste your money buying a stroker kit. just put in f22 or h23 crank and rods with jdmh22 pistons. you could buy a 100mm crank with those rods and pistons. talk to the guy at collectiveracing.com he has a bad ass 2.6L h22. he makes kits for the h22 so talk to him
