I was wondering if a type r manifold would fit my k20z1, my o5 type s? are all the k20 manifolds interchangeable? if so which ones have the most air flow?

 

ummm you dont want to mess around with the type r IM... thats not gona get you the gains .. what you need to do is look into getting the Im off the new SI.. it is the RBC intake.. this is what i run on my K20A2 its been able to put donw an exxtra 15 whp in cases.. but on the 05-06 rsx it was more around 8.. becase you guys already have a better flowing Im anyway .. it requires a new vacuum hose 3 bucks the karcepts adapter plate for your TB 60 bucks, two new gaskets, 4 bucks a piece, and might as well put the hondata intake mani gasket on there.. 55 bucks, ok, you have to drill a hole in the hondata mani gasket, thats simple enough, takes 5 seconds to do, you have to use a cut off wheel and cut the coolant housing off the intake , takes time and patience, it took me 30 mins to cut mine and have it grinded donw smooth.. the hondata IMG gives you a great stencil to use as a guide.. after thats all done bolt on the karcepts adapter using supplied harware and those gaskets you bought and bolt the IM on.. yer done but you need kpro to tune it to make power other wise its not worth it and you could actually lose HP.. more info on this on K20a.org.. or contact karcepts.com and he will tell ya all about it..

 

yeah that
go for the rbc (from 06-07 si)
its a pretty good mod
here's more info and tests

Austinite is also my tuner

 

i read this all and this is pretty interesting. would i be able to purchase everything seperate if i wanted to? i found online the manifold for the 07 si for 160!

 

yep you can purchase everything seperately if you know what you're looking for. I'm about to get my RBC here in a few weeks and tune my car meself. Gonna love it.

 

correct.. i think i spent a lil over 200 bucks for everything .. got mine for 165 shiped from autoway honda in Fla.. ask fer bert if you use that. and got all the oem stuff from him as well. went to karcepts.com and got the adapter.. its gona cost me 250 to have it ported.. im gona have that done prolly in the winter... but it isnt required.

 

yeh. get the gasket at hondata.com

 

i found it cheapest at clubrsx.com... infact i think they are the cheapest for a lot fo things.. look their for things first.. then k20a.org and PM berto about oem parts

 

ok my honda-tech buddies of mine in the rsx section. I am gonna purchase the si manifold sometime in june. what exactly do i need, im kinda confused, im thinking about getting it from honda website for 160 but im hearing from you guys i need other **** with it. where exactly would i be able to get everything that i need? thanks

 

and btw i have a buddy of mine with a 03 base rsx who wants to buy my k20z1 manifold after i put on the rbc. would his throttle body fit? how would this work?

 

read my last post
the links should have all the info you need

 

is it requiered to cut the intake housing on the rbc intake mani? can it bolt on without cutting it?

 

yes, it does require some machine cutting
Austinite in the like sells them precut, even a package i believe with everything you need

you just have to talk to him just to make sure

 

who is Austinite? where can i contact him and how?

He does sell them precut and with everything for 299 + shipphing which is 30 bucks. Pretty cheap. You can get it on ebaymotors.com is where i've seen him sell them also. just type in RBC and you'll find it.

 

nevermind i just read your previous posts, i should read more lol but thanks, i apreciate your help

 

.

 

Here is my RBC manifold.

 

did you have to remove the battery from the engine bay to make the intake fit or you just did your own thing? btw where can i find an aftermarket throttle body?

 

from the pic it looks like a custom cold-air intake
the injen one works just fine with the rubber elbow
for the aem and fujita people, they would have to cut a section of the pipe and replace it with the rubber elbow
(injen sells those seperately also)

 

thank god i have an injen cold air intake. im not too sure but am i able to bye the washer fluide replacement bottle seperate if i wanted to?

 

any more pics anyone?

 

i dont have pics yet.. and injenonline.com you can buy seperate parts
