im a long time b series fan but new to k series

i just got a 2004 tsx stock everything 6 speed

not planning to do any extensive internal work just boltons

after some light search it seems like rbc manifold and the newer 066-08 tsx cams are popular upgrades
is there a popular combination of boltons that is proven to work best on stock motor?

i plan to get the following:
intake manifold
bigger throttle body
injectors
short ram
headers
cams
and dyno tune of course
thats about it
maybe someone can link me to a thread

rbc or skunk 2 Intake mani
74mm skunk2 alpha throttle body
410 cc rdx injectors or maybe ID750s
do yourself a favor and get a nice 3-3.5 inch intake that places the filter in a colder place than the engine bay
skunk 2 alpha header if budget, ASP if you got money
cartel DIC cams make good power without having to change valve springs, but they cost $1k, go with 06-08 tsx cams if you want a 5 whp bump for the cheap
flash pro and a competent tuner and youre all set

edit: 3inch exhaust would also help

what kind of power will i be looking at with those? rough estimate?
and what about the RRC and RBB that i see tested on k20a from superstreet shootout?
which one would be better for k24?

k20z1ej1

240-250 dynojet. RBC would prob be better. RRC is better suited to 2.0 liter motors that carry power above 8500. Your engine should peak around 76-7800. Plus, RRCs are expensive. For the price of an RRC you would be better off getting an S2 ultra street.

ok thanks.
which header is best bang for the buck i definitely cant afford ASP thats too much baller lol
and whats this thing about using j series throttle body? i saw it mentioned on some page and cant really find much info about it

k20z1ej1

skunk2 alpha or PLM will be fine. j35 throttle bodies are 68 mm - too small for a k24 in my opinion. j37 is 80mm inlet/70mm outlet and would be better suited for a 2.4 liter. i know you will need an adapter to use either one, but i dont have personal experience with j series TB's, maybe someone else can chime in and help you with that aspect of your build.

oh yea thats what it was.
thanks

would it make more sense to boost the stock motor without changing anything?
i was a big fan of NA b series always but this being more of a daily i dont want a loud exhaust anymore like my b series had

how good is the factory exhaust on these things?

blackeg

my 04 k24a made like 195/175whp with just some basic bolt ons in my rsx.

short ram with a velocity stack and custom heat shield
plm header
2.5" magnaflow high flow 200 cell cat
invidia q300
kpro tune

. this is still with the rbb, which i wanted for the low end tq its my daily driver. the motor is at 155+ wtq by 2500 rpm. tq starts to fall around 6400 and power flattens out above 7000 but its great around town. I would imagine with a mid 60mm tb and different im it would pick up another 10-15 hp and tq.

the q300 is a quiet *** exhaust for its size on an all motor setup. id say its just a tick quieter than the 2.5" catback and vibrant muffler i had on my old b series em1 but the q300 is a 2.75" . I do highly recommend the magnaflow cat, it helps eliminate the rasp (i have 0 rasp) and stops the occasional exhaust smell that gets annoying with the windows down.
