looking at buying 70MM throttle body wanted to know if i need to port and polish my intake manifold? wanted to know what are the pros and cons of this?

Sticky2k

you will need to port the manifold to to match

from what I heard its a waste of money and doesn't net no gains

i have a 70mm on my car now and a ported IM. the gains are ok. u can port the stock TB or get a 70. for the price i would get a hondata IM gasket ($50) and put it on yourself, i also have done that

well do you think its worth the money for the gains for a cai intake and a throttle body? if not what kinda of mod should i get to gain a little more hp?

i have a 3" true cold air but most ppl go with a short ram because of water. cold air will give u more gains, ur choice. i would get a intake b4 a TB then see if you want to spend the $ for a new TB and port the IM or just port the stock TB. let me know what u decide and i could prob help on the price.

well i want a short ram because i am 1 of those people scared of hydro locking so... i was thinking about getting a short ram and tb together. what do you think? or would it just be better to port the oem throttle body and buy a short ram? because i don't really want to p/p my intake manifold.

if u r not going to port the IM i would just port the stock TB and do a J's style short ram. but if $ is a prob find some 3" pipe and put a velocity filter on it.

You don't want a short ram, it will not net any gains at all. Get a snorkel that fits the stock intake if you are scared to run a true CAI.

I highly doubt that the best CAI, Ported IM and 70MM throttle body will get you any more than 10whp combined, total waste of $ unless you're getting some other parts that will require the whole system to be opened up (increased compression, cams, race header, cat delete, race exhaust, stand alone tuning/Hondata on 06+) or you're FI with at least 7-8 PSI.
