Here is pics of my custom build ITB which work with stock bored MAF and stock ECU with Group A rally chip.

But you are the only one who post here :-((

It is great idea how to have ITB with stock ECU!!! AND it works GREAT!

Just curious what the real advantage is? You still go through a stock (but bored) MAF. The fuel seems to be injected in relatively the same place (One injector per cylinder). Is it that you have 4 butterfly's that are closer to the port? I am curious what advantages this offers over stock type IM.
I am not trying to be critical, I am just trying to understand.
BTW The workmanship looks great!

Hi Lander,

I got spare GSXR-750 TB in my garage, too but I have done this.

http://www.teamswift.net/viewtopic.php?t=19770

How did you make airbox?
Are you using trumpets or sub stucks?

I'm interested to see close up of air box, if you don't mind.

Cheers
Atchi

You get better reaction of engine, throttle bodies plates are much more closer to head as in stock, better intake manifold atc... And also in future when I will have EMS, I only remove airbox and will have open ITB system.

I was also thinking about buying carburators from R1, but deside for ITB.
I am using stock stacks.
Sorry, no closer pics of airbox... there is nothing to see, but because one part of that airbox is from macrolon, you can see inside :-))))

Basically what he is doing is creating really short runners. A short runner on an intake is what increases HP while a long and big runner which holds more air typically creates more torque. He'll probably find that his low end torque is suffering from this mod but the top end power will be very good and the car should be very responsive from a throttle standpoint.

all very nice for a race car and well executed, but for a street car you also lose the vacuum for your power assisted brakes. short runner intakes don't build much vacuum.

looks good lander. tear 'em up at the track. :D

No no, there is vacuum line for brake booster, you can see conection on second pic. I am able also to install ISC, but there was no problem with idle. I only need to synchronize throttle bodies together.

I just removed my booster altogether... stiff pedal but still brakes very well and locks up fine if need be... had it like this for a year and its my daily driver on the street

I have been looking at doing ITB. But I need to save up the money. I want these. I know they would only do as good as the bike ones. But they are smaller. So more room to work with. Plus they look real good.

http://www.tweakit.net/shop/product_inf ... etail=true

If anyone were I can get them at a better deal let me know.

GusGTI can you post some pics or PM or email me. On your manual brake conversion.

What is the thing hanging off the table connected to the vacuam lines? I am thinking about putting the same tbs on my car. Need some more info on how you did. I got the manifold flange and how to connect the tb to the flange. Is there anything else I need to worry about? I can also fab up the box so that is not a problem. was it worht the it to do the ITB's?

I don't know for a fact but taking a guess i would say a little plenum thing to convert from 4 hoses to one to then go to a map sensor??
