JDM parts for prelude

ay guys i never been here before i hope you dont mind me asking a few questions. i hope you can answer my questions.. im in the process of modifying my 00 prelude. dont worry im not a ricer. i love to work on my cars and im not making it fast for the chics or to be cool. i just have alot of money and lookin to spend it. anyways i found some JDM parts and i was wondering if you can help me out with some stuff. the intake mani for example.. it comes in 2 parts the upper and lower part. do i need both? also the exhaust mani.. its only the part that goes from 4 to 2 pipes where is the part that goes into 1 pipe or do i just attach it to whats already there? what the heck is the JDM bypass valve body? also is the JDM throttle body the same bore as the JDM intake? or will i have to port the mani or the throttle. i hope you can help me out cuz the other forum hates preludes and they didnt help me at all.. bunch of civic lovers. i got nothing against civics unless the guy modding it is a ricer. thanx again guys

All the parts you're listing are from the JDM Type S. They should all bolt on your car. If you add the high comp. pistons I think you'll end up with about 220 hp.
