germanCTR

GeniusTech

Thanks... does it make a big difference putting that on

For which car? For an rsx-s, yes. For an EP3, not unless it's boosted.

Also, you will only see gains if you get it tuned. I've heard of people losing power with it just bolted on.

nahonda04

truth!!

germanCTR

really NOT truth!!

with stock ecu i gained 2hp and 3nm trq

tuned with kpro i gained over 45hp more at 6000rpm contrast with stock ecu (NA!!)

DVC2008

Every motor is different. You may have gained and some may have lost. RBC is the best stock upgrade you can buy.

turboteg2nv

Yes it is, for a K20A3 motor. Obviously the K20A2 head flows better and will realize the benefits of this IM without a tune.

I lost power with it on my K24a2

I'm thinking about selling it and putting the stock on back on.

^^ Post more info on your setup. Do you have Kpro? N/A??

Type-Spaz

Gotcha. Is the K24a head the same as the K20a2 head? Obvioulsy if the heads are different and have different flow characteristics you won't see any gains.

People are only realizing power gains with the K20a2 and new K20z3 motors for N/A, people with F/I are seeing gains across the board.

How much power did you lose? Do you have before/after dyno charts you could post? I like raw numbers and facts, not just hearsay.

Type-Spaz

I gained like 3 hp in the last couple of RPMs but between 3-6000 rpm I lost both hp and torque. I'm heading to my tuners this week to pick up some parts I'll ask him to print me off some of my charts.

nahonda04

and you also have a CTR motor! we in the states do not have CTR motor stock! plus what was also said about how it varies depending on setup/motor/tuning..

germanCTR

yes you're right
didn't payed attention to that, sorry!

but a friend of mine has a k24 swap with k20a2 head and the rbc
works really well , he got alltogether 270hp and 270nm trq

turboteg2nv

I rest my case

GeniusTech

whats difference k20a2 and a3 is it the 02-04 is a3 and 05-06 is 05-06?

nahonda04

about 40hp and i-vtec, real vtec anyways... 02-06 base model rsx has the a3 and the ep3 all years has the a3

GeniusTech

oh so the type-s is a2... then whats k20z3? dc5 type-r?

eMpAtHy

k20a is what the ITR has.
k20z1 is what the 05-06 type S has.
k20z3 comes on the current civic SI's, but i'm not 100% on this
k20a2 is what comes on 02-04 type S's.

Hate to be "that guy", but there has been discussions about the RBC IM before.

GeniusTech

I just asked what it standed for then everyone else just started talking about other stuff, so I started adding along.... w.e

the king.

if you google rbc manifold the first thing that pops up is a place to buy one
