Well Summer is here now and I hadnt picked up a project yet so I figured it was about time to find one. I just got a Stock 95 GSR that i havent really figured out what I want to do with yet so it was kind of a tough decision, I currently a college student paying all my bills so I had to keep it VERY low budget. I started looking for a deal on ebay when i found a set of '03 954rr ITBs.

So i decided to take em. I figure it will be a fun build that not all that many people try. I have been doing alot of reading and realize that alot of ppl end up hurting power so i thought a real good thread including theory and opinions of some guys that have built DIY setups was in order. So please, if you know of any sites with good ITB theory info (doesnt have to be honda specific) or informative threads, or you just have an idea POST UP. Lets try to keep the BS minimal I would like this to be something sticky worthy (Does AM not have a FAQ thread???)

I will be keeping this thread updated with my progress as well.

<U>Cost:</U>
'03 CBR954RR ITB's $40.50
'03 CBR954RR Air Stacks $44.00
OEM GSR Mani $?
Al Tubing $?
Vacuum Manifold $?
Gasket $?

Stripped ITBs (forgot to take pic before i stripped them)








Has anyone used the itbs that had the secondary butterflies? I am going to plug these holes although i havent decided which way i will do it.

Have you read my post yet?
its in my sig

Those are not 954RR ITBs, look much more like Yamaha (probably R1) ones instead.

dornon13

That would make things interesting... here is the only picture i have of the full assembly.

All the electronics appear to be made by Mikuni if that helps?

THose are alot different than my cbr 954RR itb's

dornon13

do you know what year yours are?

rushi

Honda ITBs are made by Keihin. That last pic you dornon13 posted is 954RR ITBs. I've '04 with those same bluish green 12-hole injectors.
BTW I measured those injectors, they flow 320cc/min with stock 954RR fpr and Civic DPFI pump.

What size are your butterflies? Mine are 42mm, and throttlebodies taper into 41mm at exit. Intake side ID is 45mm.

yeah those arent cbr954's

keihin does alot of itbs and intakes and carbs so.. its useless if we're gona base things of the keihin brand..

cuz my gsx-r1000 is stamped with mikuni..

dornon13

i havent measured the butterflies but the inlet is like 52 and the outlet is like 45 i didnt have my calipers so i had to use a scale.

dornon13

ok i just realized what you said and i agree...the picture in the auction is NOT what i recieved

d15Beta

wow u sir have a big *** itb.. haha

it falls in the size of sumthing im looking for.. hehe

dornon13

I will later, If this guy wont trade me for the correct ones i will prolly sell them to you for what i paid

d15Beta

well i need to know what they came from what year etc,

also.. how much..

bfor i consider them...

i already have
gsx-r1000 =42mm
cbr954rr = 42mm
Cbr1000RR= 44mm

dornon13

d15Beta

dornon13
