Valve springs + K20 intake manifold

[EUR003act]

hey guys,

im looking at getting skunk2 stage 2 (or 3!) cams... im guessing ill have to upgrade my valve springs and retainers... anything else i should look at doing to run the cams?

thanks

[ALN]

I got the magazine that showed the Skunk2 Project TSX that made 240 hp at wheel. Skunk2 mentioned that stage 1 is the best cams profile for stock bottom k24a2 since you can't really rev it more than 8500 rpm, there will be only very little clearance for the piston.
Anyway for the valve spring and retainer you needed to made power up to 8000 rpm however titanium retainer has lifespan from what I gathered it only last 10k km up to 15k km.

[EUR003act]

thanks for that ALN... so i only need valvesprings and retianers if increasing my rev limit over 8000rpm...

does anyone else know if theres any disadvantage (besides economy) for going stage2 or 3?

also, will a K20 intake manifold fit on a k24? yes i know id have to modify the throttle body plate... but i like the larger plenum off the k20 and can upgrade it to a h2p one aswell

[fatfish]

i think to full recondition of the cylinder head with the cam will even better.
this is what i am going to do early in the year

Not really, aggresive cams are the one that produce power and valve spring retainer made it easier to reach higher rpm.
Hmm for stage 2 and stage 3, it will affect the idle and daily driven situation and it might required to do crankshaft and rods to be replaced with lighter and strong one to pass reach 8500 rpm or pass it.

k20a intake manifold has 2 good options like PRC from ITR and RBC from euro R. PRC will require to modify the water port and RBC will directly bolt on to K24 euro. There to be found RBC is better than PRC in term of flow however it will only serve better with aggressive cams combo and will lose power on stock cams.
You could try 06 TSX intake cam in which from what I heard to be better than japs spec ITR cams and it manage to make 15 hp more on the top compare to 04 spec.

[EUR003act]

sorry excuse my ignorance... whats PRC, ITR and RBC? cheers :D

[ALN]

PRC is intake manifold found from jap spec DC5R and RBC intake manifold found in Euro R. RBC also recently found in US 06 civic Si. In skunk2 project TSX, they used PRC to made around 240 hp at wheel however that was in feb 06 which the RBC was not yet tested by many k series hardcore users.

[EUR003act]

so i should try get the RBC, easier bolt on mod...
thanks again

[ALN]

no worries. Just try this website http://www.hondapartsdeals.com/
Prob, one of the cheapest online store and good luck with the project.

how about the japan ctr Fd2 intake manifold will it fit to our car, i am thinking of putting the fd2 intake manifold and the spoon made throttle bodies on to our car, do you think it will work?

[EUR003act]

hehehe couldnt help myself... just ordered the RBC from a DC5 RSX/EP3 CTR...
it comes with:
-RBC INTAKE MANIFOLD
-"KARCEPTS" RBC ADAPTER TO MOUNT STOCK THROTTLE BODY
-GASKET - BETWEEN RBC MANIFOLD & KARCEPTS ADAPTER
-GASKET - BETWEED KARCEPTS ADAPTER & STOCK THROTTLE BODY
-VACUUM LINE - TO CONNECT RBC TO STOCK VACUUM FITTING
-HARDWARE TO MOUNT STOCK THROTTLE BODY TO KARCEPTS ADAPTER PLATE TO RBC MANIFOLD
(im not sure if ill need the TB adaptor as i think the RBC used drive-by-wire thottle anyway?)

i should have it within the week, ill install it when i put on my Hondata heatshield gasket, and do my throttle body coolant bypass :D

should work well in conjunction with TODA headers and K&N CAI...

now i just gotta save up for skunk2 stage 2 cams and jtune mild reflash :D

The TB, I guess it could fit to our euro since the TB of the FD2 is exactly the same with DC5/CL7 one with only difference in the system. I red from civic si forum that few of the members replaced their stock 60 mm tb to 06 TSX 64mm TB and it worked.

The intake manifold is new design which only available in FD2, but then again I guess it could fit our euro and if minor mods required it would be the water port. :D

FD2 are damn good though from the chassis, transmission to engine. It has adopted NSX tech :thumbsup:

Did you order the Euro R intake manifold? I remember reading somewhere that installing it on the K24a engine caused it to lose power. The shorter runners are designed for high end power which suits the K20a but not the K24a.

i think its the same as the euro R, i know its different to the K20 manifold off the S2K and ADM DC5, they use a more snail like intake... yes the shorter track will lose power low down, but it gains up to 7hp top end... and when used in conjunction with CAI, headers, and reflash, they obtained about 15hp gain... it'll also give me more room to move when it comes to cams and headwork...


The stock RBB manifold is uses a long narrow runner which is good for torque, whereas the RBC intake from the Accord Euro R uses shorter fatter runners optimized for high rpm breathing. The RBC intake is a direct replacement for the RBB

you can see below the intake tract on the RBC is actually about the same length as the PRB, but doesnt snail around, allowing for free'r flowing air :)

i have the stage 2 Skunk cams in my k24 civic, and i love em. i have standard headers which really restricts room to me to move, but mid-range to top-end is pretty intense, heaps more torque. you wont be disappointed if you decide on them.

personally, stage 3's are nuts...send a PM to Dr Honda for more information, he has them in his civic.

good luck

did you do any more engine work besides cams? like valve springs or anything?

thanks for that, good to see a real life example :)

Tb adapter got nothing to do with drive by wire system.

people use karcept TB adapter to run K20A throttle body on RBB and RBC intake manifold.

i was going more down the line that the adaptor was made for non DBW TBs... and i was under the impression that the RBC was made for DBW TBs (CTR and ATR) so i wouldnt need it...

im kinda in a modding mood today... as soon as my bloody TODA headers arrive (still waiting after 8weeks!) and i get the intake on, ill go get her dyno'd :p

[Suntzu]

Is custom tuning needed with Cams? or would hondata do? Might pay to see what they come up with their cam/flash/extreme package we know how long this might be....

[EUR003act]

thats exactly what im wondering!

im pretty sure id need alot of tuning for stage 3... but would i get away with the jtune mild flash for stage 2 cams?

[LUD35]

i have skunk stage 2 cams with stage 2 titanium valves and retainers. Dr Honda built the motor for me.no other internal work other than the cams and ARP head studs.

im running a k-pro, so no there arent any "custom" tuning specifically for the cams.

From the TSX forums:
since the RRB and the RBC are newer, they require the use of a Drive-By-Wire throttle body. Since the K20A and other models are not Drive-By-Wire, the throttle bodies do not bolt up. You will need an adapter plate used in conjunction with a K20A throttle body and cable

the adaptor plate is only for non drive-by-wire TBs... so i wont need it for the k24a

You also need pistons, rods, pins and other goodies in the block. Otherwise the engine won't last spinning to over 8000rpm.

Yes, you should get proper tuning if you are replacing the cams.

is there anyone that does custom tuning for the euro? do i have to get piggy back ecu (apexi AFC/NEO or similar) or can you just tune stock?

[aaronng]

VAFCii and the Neo are insufficient as they cannot control VTC and ignition timing. You will either have to get a custom reflash or go k-pro using a harness and a k20a ecu. There should be other brands of ECUs available for the Euro and those will work as well. Before choosing an ECU, I'd choose a tuner first.

id prefer custom reflash... as i dont want to loose cruise control/VSA/air con and all that other stuff you loose when changing to k20 ecu...

Use the Hytech k24a/k20a ecu harness. You run 2 ECUs. The k20a with k-pro runs the engine and the k24a runs your A/C, cruise control and it might even keep VSA working (just guessing though). Downside is that the harness costs a few hundred USD, and a k-pro'd k20a ECU isn't exactly cheap.

[EuroAccord13]

I'm trying out the JDM DC5R intake plenum as well as the CL7 Euro R intake plenum, we'll see how it goes along with custom headers and ECU.....

The shorter runners delivers power @ around 6000 RPM and hence with our rev limiter, we are restricted to 1400RPM to play with on the powerband... This will be interesting....

if you get yours installed before me ull have to tell me everything!

don't forget if you using the JDM DC5 intake, i think youll need an adaptor for the water bypass on the block?

[fatfish]

what ecu can i use for auto car with k20 head swap valve spring, and cam change. will the stock ecu with vafc able to run

[EuroAccord13]

VAFC will only allow alteration of your A/F ratio and VTEC engagement points. A good tuner will be able to work out the best combination of these two parameters.

It is unable to alter ignition timing and control which alone can make good gains for the car.

sorry but thats incorrect, depending on what kind of car the motor is in.

keep in mind there are 4 types of k24's, k24a1/k24a2/k24a3/k24a4

k24a1's have the weakest bottom ends of all k24's, these are not recommended to be revved above 7900, and are weak motors, these come in bottom of the line CRV's(i think). the other's have stronger rods and pistons and can be taken up to approx 8200-8300 depending on other mods.

all that is needed to make a k24a2/a3/a4 rev all the way up to 9000rpm is forged rods and pistons. then again, you must remember that alot more work ontop of that must be done to make power all the way there ei. high end cams.

there is alot of information on this very subject at k20a.org

You're saying the same thing that I said. :) Take a stock K24A3 block, put on aggressive cams and Type R valve springs to prevent valve float and tune the ECU, you'll still get a hole in the block after revving it to 9000rpm say once a day for a month or two.

[LUD35]

ok cool :) im glad my information is correct

I agreed with aaronng, if you search again on k20a.org there are a lot of discussion of k24a no matter which type, a2 or a1 can't really stand above 8000 rpm since the piston contact clearance unless rods and the crankshaft are to be replaced.

Just for reminder about the RBC , it has been discussed and tested already that can only works with aggressive cams in k24 engine. Stock k24 engine will suffer low and mid range power however the small gain will appear on top. However RBC to be found to produced higher output with combining with aggressive cams compare to other Honda's intake manifold. Anyway good luck, keep us posted.

[EUR003act]

at 7500rpm the K24s pistons are travelling at the same speed as the K20s doing 8500rpm... therefore, yes it'd probably destroy the engine doing 9000rpm... but im not looking at increasing rev limit... i am just talking about getting intake, skunk2 stage 2 cams, and ecu reflash...

The way cams work is to alter the point at which peak torque occurs. Since the Euro makes peak power at 6800rpm and peak torque at 4500rpm, you can expect that when you shift peak torque up to 6000rpm, you can make more power at over 8000rpm.

Assuming that you manage to push say 223Nm at 6800rpm using the stage 2 cams, that's only still 158.7kW. Say you lose some torque and hit only 200Nm but at 8000rpm, that is still 167.5kW!

ive heard its way too dangerous running it tho... especially if you change rev limit to 8500 >...

piston + valve = bad !!!

[aaronng]

Technically, the VTC shouldn't use the full 50 degrees if the ECU sets it to engage to a max of 40. But then again, having a physical 40 degree limit is always better.

[EG5]

My EGK24A only rev to 7600rpm
50 degree VTC is save , it max out at 45 degrees on my KPRO.

[EUR003act]

hey guys... couldnt get replacement fuel line from honda till january :( so i had to make up a custom jobby for the meantime... started the engine tonight, no fuel spraying everywhere!!

First Impressions:
took 5-8secs to crank over, then a lil jumpy on idle at first...
sat on 1600rpm for a min or two...
as it got warmer dropped down to 1200, then rested on 900rpm for awhile...
at correct idle temp, runs on 700-750rpm (same as before)...
There is also a distinctively different exhaust note, its more "airy"

Test Drive:
Starting off slowly in 1st, changed at 4000 to 2nd, then 3500 into 3rd...
i noticed when drivng in a gear, then going to neutral, the revs drop quickly down to around 700, then bounce back up to 1400... it does this when going from anygear into neatral or when pushing in the clutch...
Luckily, that only did that for 5mins, then changed to only dropping down to 1100rpm when moving in neuatral, 1000rpm when u first stop, it then drops down and rests on 700-750rpm after sitting for awhile (same as before)

Driving WOT 1st gear, maybe slight loss in power below 3000, hard to tell... 1st gear 6-7000rpm only lasts a second, and let me tell you, when vtec engages, the engine roars! huge difference there, the CAI no longer grumbles with vtec, but screams...

2nd gear, maybe also slight loss in power, if not the same below 3000, between that and 4500 seems the same, but once above 4500rpm definate improvement, 5000 to redline goes very very quickly! once again, vtec smashes through the last bit of rev range...

3rd gear, much the same as 2nd, this is where i suppose jtune reflash with 5000 vtec engagement would make huge difference, this manifold really seems to love high revs :D

4th gear i didnt get to test fully :p, but up until 5000 she goes nicely... no lack in power as she pulls past 4500

I forgot i took this pic, it shows just how good modern day casting is, i cant see porting getting much more power (if any) off the k-series

[sodaz]

Very nice mate! Thanks for posting your impressions so quick. :thumbsup:

It seems like the IM shifts the power from down low to high like a pod style CAI does. There's a bit of sacrifice in daily driveability to improve peak power. The Jtune mild reflash will lower VTEC slightly so it should improve things. I'm a bit concerned with the lumpy start up though. Things could change in a few days though as the ECU is still adjusting to the new setup. :)

Nice mod. I'm hoping to find an RBC manifold too. where did you get yours?

Any pics of the cover installed? and if you wanted one quicker or cheaper I could have found you one. I just got one for $30.

If I end up getting a PRC intake manifold, does anyone know what's involved in modifying the the water port?

[krogoth]

give us an update, lol

i installed the cover yesterday :D yay! finally lol... ill try get pics up tonight.

i got mine off ebay, theres a guy who sells them for integras/civics, he normally sells them with the water port cut off, and they come with a throttle body adapter... but i got a uncut one from him. ill try get details for you

you got RBC manifold cover genuine honda for $30?!?!! thats heaps good! im thinking of buying another one, scratched mine alittle installing it :( i was in a hurry lol oops

yeah i know what needs to be done for the water port, ill put instructions up once ive written some...

[EUR003act]

give us an update, lol

well while tony was down in canberra (hey tony!:D), i let him drive my car... he didnt push her hard, but he couldnt feel any loss in low/mid end power, said it felt about the same as his '06 (only comptech icebox i think).... so we're both thinking maybe ive just lost some of the gains i got from headers/pulleys/etc... it was a very hot day, so we didnt really get to test out the top end, but he took me for a drive in his baby, damn she handles well! i gotta get myself proper coilovers!

[aaronng]

Last I drove an Euro with Toda headers, it was like night and day compared to a stock Euro. In my opinion, having your low end go back to a similar feel to an Icebox-equipped Euro is quite a power loss. But then again, Tony's Euro has a pretty strong engine compared to mine.

The Icebox has improved the mid end and even the top end a bit with minimal increase in noise.Cost me approx.$260 shipped,good value.I'm still running the stock top piece of the intake with a K&N filter(thanks euroo3act).Not sure what difference in power the top piece will make when i install it. Id be interested to compare another 06-07 manual with mine,as Aaron said mine seems to go hard for a basically stock engine.:confused:

I changed my engine oil after we last met up and it was a big improvement. The oil I had in the engine had seen a track day. When I drained it out, it was black and a little gunky. Even with the improvement, my car still doesn't have that mid-range lump of torque that your car does.

Good to hear.Is there anyone here that can confirm if there was any change to ECU mapping or whatever between an 04-05 to 06-07?from what i know there was no changes(apart from strengthened rods and crank)to the engine from 06 onwards.

you see i didnt find much difference with the headers... i felt more of an improvement in power after installing CAI... i dont know, maybe my butt dyno is compltely out :p

anyways, i finally got pics of the engine bay complete! it hasnt been cleaned or anything, but i know alot of you were desperate to see the final result!
so here she is:

i bought and modded K20 euroR intake manifold and installed on my K24, so i needed to get the euroR IM cover to make it sexy :D

FYI the 2.0 doesnt stand for 2L... its how quickly the car does 0-100km/hr :p haha

[Pumped]

Does changing the intake manifold to the RBC decrease the Capacity of the engine?
i heard it does, if it decreases it to 2L does that mean it will rev higher now to?



*insert sarcasm*


Looks good :)

[tony1234]

Hey Justin i'd return that cover.It'll make your car slower!!It's turned your engine into a 2ltr.hahaha.;)

Hey guys (and girls)

the latest update in my intake setup... Power Rev Racing throttle body spacer (for the '06 Civic SI) and P2R throttle body thermal gasket (same as hondatat IM gasket but for TB)...

on the K20 the TB spacer sees gains of around 4.5hp atw (dyno proven)... not sure what kind of gains ill get on the K24, but hey, ive basically run out of bolt on mods :( lol and at only $80 it was pretty cheap

[fatfish]

looks very nice
have you drive around yet?

[EUR003act]

looks very nice

THANKS :D

yeah i have driven... i can feel no difference lol but i couldnt feel a difference with toda headers lol

the TB definately stays cooler tho! now i just need to heat sheild my k&n typhoon piping... it gets sooo much heat soak! :(

[aaronng]

I'm very skeptical about the 4.5hp gain using a TB spacer + insulating gasket.

[curik]

I seriously doubt a spacer gaining 4.5hp as well. I just couldnt find its merits from the engineering point of view

[EUR003act]

I'm very skeptical about the 4.5hp gain using a TB spacer + insulating gasket.

lol yeah, as i said, i cant feel anything, but its another thing to add to my mods list, and it was cheap :) lol

we'll see how everything goes when i get it dynoed

[EuroAccord13]

Find a dyno that is properly calibrated too :D :D :D

lol thats the hard bit! :p

[BusterSonic12]

no worries. Just try this website http://www.hondapartsdeals.com/
Prob, one of the cheapest online store and good luck with the project.

that site doesn't sell any integra parts??

[aaronng]

DC5 is considered an Acura in the US.

[Crapdaz]

just wondering where you can source the manifold from? and was there much trouble or pretty much direct bolt on?

[enkay]

u can get the rbc from jdmyard
