I'm not sure if there are any ITB's on the market designed to work with DBW? You'd probably have to convert the car to cable throttle.Quote:

Daz and Russ... can please post pics of your RBC with the nipple already there? im interested to compare the intakes...
and confirm your using the correct nipple :p lol
cheers guys! :thumbsup:
Our nipples didn't come from the direction where you installed yours :p, its located on the side just above the PCV on the manifold.Quote:

I havent got a current photo but i can tell you mine has the correct vacuum line next to the large one. It exactly the right size for the hose. It works perfect and makes the install easy.

They were probably supplied with Civic Si RBC manifolds instead of EuroR RBC manifoldsQuote:

im sure if you order a intake for the euro r it should work fine on manifold.
You know how the Injen has that black rubber bit which joins the two halves together? If that is not enough to give you proper fitment with the RBC, get a longer rubber/silicone joiner.Quote:

only because it comes with the nipple already there. :pQuote:

whaaaat!!!
found out something interesting today...
when the engine temp is below 30degree C - VTEC will not engage :eek:
lol and no, i wasnt revving the sh*t out of a cold engine, the engine temp was actually 92degree and oil temp 85degree... ECU just thought it was cold (trying to see if on cold start the engine advances ignition / increases fuel)
hehehe :thumbsup:
I didnt hear from you today, is it idling better?
hope so!
Any news justin. We are really keen to hear whats the status is!
hey buddy :)Quote:

ok so update is:Quote:

as for the stock ecu - when running with the J32A3 throttle body, the a/f ratios sit similar to what they used to, except under vtec... they used to sit around 11, they now lean out to 13.5... so im loosing power there!
im playing around with my options, i only drove it around for a day, so given more time i can see it learning... otherwise i may go piggyback ecu :zip:
oh and some pictures - sorry havent posted any in ages!

TODA headers at 2200rpm idle:
http://i239.photobucket.com/albums/f...F2515Large.jpg
thanks for the update!
The toda headers look good glowing like that - nice and even too so the flow is obviously pretty damn even across all primaries. How did you take that picture (how hot does the manifold have to be?)
I'm also curious as to why you didn't just change the cams? I'd always thought that in terms of flow the Accord euro k24a head was essentially the same as the DC5r k20a head?
You're probably getting sick of me saying this now, but...
definitely get this thing tuned! You're really not going to make the most out of the k20 head and all of your modifications unless you do. I also want to know what the real gains are when changing heads!
I think Justin wanted to prove that you could get good gains even without getting your ECU tuned. :thumbsup:Quote:

As long as his AF ratios stay below 14:1 and there isn't pinging. :thumbsup:Quote:

yeh, direct bolt on. Wait for ECU....Quote:

Usually Honda's retard the timing on cold start & use the idle speed motor to bring the revs up.Quote:

Try replacing the fuel pump reg in the tank with an adjustable unit.Quote:

yeah i was looking at raising the fuel pressure... or something like that...
as for the retarded timing, yeah, it didnt run aswell when it thought it was cold lol
so thats why my car idles at 1600 rpm in the morningQuote:

nice, looks like the car is still performing well even though it's still not running right
Thats awesome. How did you do these calculation in terms of spped and weight? Whats that the GPS thing?
dont believe those figures until you run at an actual track. G meters etc arent too accurate.
I would be more than happy if I can run in the 14's over the quarter mile.
yes russ, it was with the gtech pro rr... :thumbsup:Quote:

It is reasonable if you have a level flat road. But that is usually not the case, which then affects the accuracy. If you took the Gtech to a place like WSID, then it would be very accurate because of the flat road. But if you tried using the Gtech on private roads, the numbers might be skewed.Quote:

very true :) (note to self - do 1/4mile on steep downhill)Quote:

keep up the good work !!
bump! any updates ?
Yeah whats happening! Whent he dyno? Probbaly sorting out the new TB im guessing. Hows the euc handling it?
lol sorry ive been swamped with work and stuff :(Quote:

ill post updates when they come :thumbsup:

Keen to hear how your doing. cheers mate

lol hey guys!Quote:

still havent got her dyno'd or decided on tuning option, although i will say, once i get the intake running cool, ill dyno her with stock ecu :D
following this project fairly closely.
just wondering, with the RBC do you notice alot of power gain over the stock runners? Any loss down low?
hehe yep! youll notice a gain :D and no loss down low! :thumbsup:Quote:

between what rev range?
approx 3-6kw atw gain accross nearly the whole mid-high rev range... euroaccord13 posted his before and after dyno... try search for it... :thumbsup:Quote:

Im getting a custom single exhaust as i reckon i might gain a bit with my mods.
Cant wait to hear about the dyno with the stock ECU! Fark I wish Kpro wasnt so exxey. I really want a tune with a 45 VTC~!

anyway, the latest news is im going to trial the new RSP manifold of the JDM FN2R... its a three piece manifold thats casted with the same technology used in the NSX, it was internal velocity stacks, and a massive plenum for low down torque... here is a quick comparison between the stock RBB, the new RSP and my current RBC manifold...
please note that the RSP is missing the bottom half of the plenum, its still on order from japan... :(
http://i239.photobucket.com/albums/f...2569Medium.jpg
i will hopefully at one stage measure and document on here the length of each manifolds runners, the width of the runners, the volume of the plenums, and other stuff like that :thumbsup: hope you guys like!
p.s these are f*@ken expensive to buy normally, around USD$800... luckily i got an awesome deal from my good mate michael from honda, otherwise i wouldnt be able to afford it lol
very nice!
cant wait to see how these runners go..
any chance your mate at honda can hook us up too? hehe
lol, if youre quick, its very possible, but you'd have to be quick, its my last day today @ Honda........
lol i wouldve loved to, but unfortunately he left honda :(Quote:

Like... vtec intake manifold?
can't see the image @ work, but dont the runners go from thin to thicker?
lol nah that manifold is some weird black plastic one... dont know its code...Quote:

ill get more pictures soon :thumbsup:
ill measure them tonight... they do taper a little bit... ill find out there volume and all that...Quote:

so i was bored this afternoon, couldnt go out and detail Evelyn because im sunburnt :( lol so i started polishing up my RSP manifold, ive only done the velocity stacks so far, but ill eventually do the whole runners :thumbsup:
PICTURES!!! YAY!!! :D
One stack done:

Close up:

Two stack done:
http://i239.photobucket.com/albums/f...2581Medium.jpg
Wouldn't the RSP come pretty polished from the factory?
yeah, its made with the same casting technology as the nsx... as you can see by the too unfinished stacks theres no casting marks...Quote:

haha, I'd probably do the same thing. It wouldn't feel right driving it knowing you might be missing out on a tiny bit of power because you didn't bother doing something like that.Quote:

Fairly big difference! and ill tell you now, thats all in the runners... plenums are nearly the same size...
