This are ITBs from a CBR600RR

Surprise, they came with

- TPS
- MAP
- WAX ROD (for cold idle)
- Manual Adjustment ****, for idle.
- 8 denso 12 holes injectors (I believe they are 190cc each)

I´ve read they are 40mm, but at the top they are 45, and at the bottom 42....

I dont understand how you measure this stuff

looks like a pretty good score. i don't know if you frequent some of the other Rx-7 boards, but there's a great thread over at mazdarotaryclub that may be of some help to you.

measurement is the throttle plate diameter...

those actually look very user friendly, all you need is an ecu and a manifold

Pi(r)squared is your friend.

did some one call my name?those are taperbore itb's makes them flow more to know what size you have just measure the bore diameter at the butterfly and thats your size

Those are the same set of ITB's I'm looking to get. Should work out quite well

what year CBR600RR? the f4i one or the 2004-05 one?

-xlr8planet-

iTrader: (3)

I believe the f4i is NOT the same as the RR model

What year are these going on? I have access to quite a few motorcycle ITB's so I'd be interested in this...

I was warned not to go with 4 itbs. You will not get the same flow thru all 4 intakes - So you can end up with hot spots in the combustion chamber.
Any validity to this? Makes sense as the inner and outer intake tracts are different diameters.

It doesnt make sense, you only have 2 rotors.

IF you were working on a piston engine, and you select diferent sizes for each runner ,,, then yeah you are facing issues.

not the case here...

you would be choking a four rotor with that small of throttle body size.

anyways, you should get the stock CBR 600RR venturi attachment that goes into the stock airbox and bolts onto the throttle body, I got one with my CBR 600RR ITB

RX200013B

was there any progress to this thread?

I believe we're all still working on our setups. I just ordered a haltech Platinum 1K to run mine and am finalizing the airbox.

what kind of runner lengths are you guys going to be using?
