alright, thanks man, i'm such a noob when it comes to this stuff

toda cams will definitely be in my future, probably a long installation though

Dan Martin

You might not want to tackle a cam install yourself. It doesn't take too long but I think it would be wise to fork over some cash and let a professional install them for you. Things go very wrong very fast if you screw up the installation.

madmanmax3000

oh ya, i wouldnt try something like that myself....i stick to electronics and bolt-ons when it comes to self-installs

i'm just cheap and am already thinking about how ripped off i'm going to get having to pay for a several hour installation

Toda cams do not affect the driveability and idle at all.

ITR#203

As hondata said, Toda cams designed for the K24 will not affect drivability at all.

One reason is that i-vtec is actually an inhibitor to how agressive cams can be. The adjustment of the cam timing can only get so agressive before i-vtec cant handle it. As a result, Spec B and Spec C Toda cams require the removal of the i in i-vtec. Most people would not appreciate the decrease in low/mid range torque, and Toda knows this.

I am convinced that Toda realizes what kind of market they are trying to get to (TSX owners are NOT looking for all out performance-aka wont want to remove I-vtec) as a result, they will not release any type of super agressive cams.

As far as noise goes, expect more chatter but the induction note/ exhaust note will not change as significantly as an intake or an exhaust.

i've been wanting toda cams ever since i rode in my friends car with toda cams. gains were great. you can't even really tell he had cams at idle.

but i've been hearing GREAT things about ips.

i'm anxious on what hondata has to say about the two - ips and toda; and if hondata plans to release an upgraded reflash for the ips.

kord

the gains on a RSX with toda engine kit($2300)/manifold, Injen CAI and Mugen Exhaust are supposedly at +55hp and +35tq. Will we be looking at the same numbers? Also how much will the Reflash affect those numbers? Thanks

1 last thing.. does toda plan to release one of their overpriced manifolds for the TSX??

toda > ips or is ips > toda?

ITR#203

its hard to say what kind of power numbers we will be lookin at. There is definately more potential overall in the K24 all things being equal. However, will our rods be strong enough to handle 8k rpms, since horsepower is a direct function of rpms? Will our intake manifold become the restriction at this point? Will our heads be high flowing enough to not be a huge restriction?

Scenario 1:
Since RSX type S cams (even the 02-04, they got more agressive in 05) have much more agressive intake lobes on a much smaller motor, there is more room for improvement. As a result, while the peak HP gain might be similar or maybe a bit more (55-60 hp) because we cant rev as high, expect more mid range and upper range torque gains.

Scenario 2:
Between not being able to rev high, other restrictions in the head and the intake manifold, the fact that the exhaust lobes on the cams are more agressive than the ITR cams already and maybe even the DBW, gains, while still very good, can't match the level of the RSX type S. Expect 35-45 hp and the same (30-35 ft-lbs of tq) amount of torque.

Tough to say how it will turn out, however, I can pretty much guarantee that the gains will be significant from the information I have heard about the K24 up to this point.

Of course, none of this matters to me if they dont crack the 05 ECU or at least make a wiring harness for it.

hondata

The TSX head as far as we can see is identical to the RSX-S in valve and port size.

An increase in rev limit will not happen unless you have a built engine.

All the NA K24 engines we have tuned, peak in torque about 6000 rpm and drop from there. Due to the high piston speeds and the larger capacity the cylinders do not fill above 6000 rpm as well as the K20. (forced induction fixes this)

We are investigating combinations of intake / headers / cams to find the best upgrade path. So far it looks like a race header is the next upgrade and will probably be mandatory for cams to work.

ITR#203

I see. Is there anything we can help decrease the effects of the long stroke on the K24?

I know on the K20A2, the intake manifold is the restriction that prevents hp after 7800 rpms. Maybe it's the same with the K24 to a certain extent?

Are you saying that we will continue to be limited at the same 7600 rpms as the Hondata ECU? If so, then I assume that the K24 Engine Kit will not come with valve springs, making the whole kit a bit cheaper?

The head on the K20's are pretty good...didn't EDO on Clubrsx.com only get a couple of hp, with a mild port and polish and valve job?

sigh...what to do? I know this car needs a longer header, but I really dont feel like dealing with driving around without a cat...maybe I can get the header, add an aftermarket cat and make a custom exhaust to make up for the longer length.

madmanmax3000

how much (ballpark) would it cost for the TSX cams and roughly how many hours installation?

i'm trying to estimate so i can plan my next few mods around it

Stokeless_TSX

over 1k for the cams bro...add about 200 or so for install unless your gonna do it your self

madmanmax3000

ouch, over 1K is pretty steep, but it sounds like a lot of gain for the money, right?. I did pay 900 for the 4 horsepower from the exhaust so i guess i cant complain.

is hondata saying that cams are really pointless until you have I/H/E? I just have I/E so should I get the header before i worry about cams?

hondata

Specifically, I am saying a race header will be necessary for aftermarket cams to work well. I do not believe that the existing headers on the market will allow cams to work.

damn emissions, well guess the engine is just going to stay more or less how it is

rmpage

How will a race header affect emissions?

dzuy

it bypasses the cat converter.

xizor

my understanding is that a race header has longer runners and completely eliminates the cat, no test pipe at all.

rmpage

Oh ok.

How do they test emissions in VA? Here in MA they use the OBD2 port, which means as long as the ECU is reporting no problems, you pass emissions.
