Today i was on the phone with Brandon over at Inline Four and he mentioned a customer had came in talking about his k20 RBC intake manifold project he was mating to a h22. this is the first i heard regarding this particular customization. any one else heard of this?

 

yess sir!!! seach on here and you will find the adapter...

 

yup QSD makes the adapter

 

$hit me pants there is truth behind this madness..... im gonna have to look more into this budget. thanks yous guys

 

i don't think it'll be cheap. you'll be looking at 5-600 when everythings done. unless you have everything from the k series already. my friend is going to be testing the rbc manifold against the euro r.

 

oh... please keep us posted

 

Here we go

Just some pics for those whoe didnt see.

 

anyone know the max bore this thing can except as far as throttle body size goes?

that will be a good test because i have a feeling they will be very similar.

i was gonna do that test myself but didnt get around to it. i do know the euro r runners are 9" long and i believe the rbc's runners are very similar in length. the plenums also appear to be very similar in size.

i would bet they perform nearly identical on the dyno.

 

I would be that guy that bought the rbc manifold. Its actually WAY more than 500 when said and done. Atleast for me it is mines well upgrade everything. Im going use my h22 injectors so that will save me some money. I just have to buy a fuel pressure regulator. And do a little bit of a mod to get the iacv/iab working.

adapter plate-190
rbc manifold( I got the 06+ si same thing cheaper)-180
hybrid racing fuel rail-160
bdl 70mm throttle body-300

 

i just recieved the plate
i will be testing a stock rbc as well as a ported rbc vs my euro r
hopefully be able to do this in the next few weeks, being broke sucks =(

 

will these tests be back to back same day on the dyno?

im very curious to see the results

 

yes sir
this is the setup like your old one
stock jdm block, head work, pro1's etc...

with the euro-r made 246whp, ill be using this same dyno for the rbc testing

buddy also has an ips manifold, i might throw that on for ***** and giggles also

 

dont think ya needed to spend 300 on a TB

take a look there

 

Yeah I know. Im getting a stock k throttle body that I'm thinking about boring.

 

sweet, id love to see the comparison of the 2 though

 

The runners are about 7'" on the RBC manifold compared to about 9" on the Euro-R, You could port the RBC TB inlet to 71-72mm safely, any more and you have to do a lot of modifying. Hopefully we will see some comparison testing soon. Has anyone flow bench tested an OEM RBC manifold and an OEM Euro-r????

 

Put my plate on today still waiting to port match my manifold to throttle body. I had to grind the back side where the two top left stud are in order for it to sit flush.

 

In for updates...

 

I am definatley interested in how this turns out!
I have always been curious...

 

Cant wait to see some dyno #'s

 

You can adapt more than just the RBC .................................................

 

Wow now theres a great idea.

 

That trottle body is freakin insane!
