looking to do an na build that will occasionally see nitrous. I know an ems is very important and will be purchasing one but what other types of info do you guys have. i would like to see 200+hp on the motor not spraying
 
there are many things you can do, but high compression and n2o - first thing you should look at is rods. you'll kill your engine in no time without forged rods.
 
forged rods with forged higher compression pistons
lighter flywheel
underdrive pulley
intake / header / catless pipe / exhaust
intake manifold
reworked head, ported with a valve job
engine management
get rid of air conditioning
custom ground or jdm camshafts

how much hp would that push?

the list i put up? depends on how well you had the engine management tuned and what compression you were running.
 
i'm a wally and dont realise this is a NA tech section.

well i knew i needed to go with all forged internals but who does head work to our heads? and as far as cams i was going to see if twilightprotege could get me a set i seen the group buy but it was full and im still waiting on funding. and as far as doing this setup i just wanted to do somthing diffrent and i havent seen ne one yet to do a setup like this with the nitrous.
 
what do you guys generally charge for say port polish valve job etc. what would you suggest i do with the setup im going to run
 
imo i'd leave the head alone for a while other than cams and springs. not a huge amount to be gained there. spend the money on a top of the line exhaust, quad throttle bodies and microtech before you look at head work.

brianmp5t, if you dont have anything valuable to add to a topic please stay out of it.

depends on how extensive you want it. we have a ported core here for about $899 plus shipping. it would need the valve job done to it.

200whp pre-nitrous? Drop in a KA20 with mods...
are you trying to say honda K20A?
if so, i'm curious how big is this operation would be, maybe just trade in a civic and swap the K20A instead......

LOL, yes K20A. Pretty much the only engine that easily obtains 200whp without serious internal modifications.
