Thread: SR Individual Throttle Body Design and Theory (ITB)

4 Piston Racing:: Ported Cylinder Heads
At least here they are are advertised in all sizes for $2250
I am not saying that they have to be cheap but something more affordable than $3300
TWM Individual Throttle Bodies 2000 Series itb 52mm Honda B16A B18C5 | eBay
Even the TWM ITB's are listed for like $1409 on ebay and they are not knock off's
Just saying!!!
I dont mind paying a reasonable price for a part!!!
Happynole!!! I was one of the first members of SR20FORUM.COM that PAID!!! the full price on a Hotshot gen 6 header with my nickname engraved back in the days!!!! jajajaja

Perfect thread. I will be following this.

can i use 750cc injectors on the gtir itbs?

So i keep on reading that 48MM ITB's are too small for a VE head. Can someone confirm that the Stock Runners' ID is larger than 48mm? Im determined to use the ITB's i have now..if it means boring them out a mm or 2 if possible...
Here are my ITB's BTW.


My plan is to either get a plate/adapter to fit my VE OR just cut the bottom flange and weld on a new VE one. Either way, i would like to get this to work.

What about other factory ITB setups that may fit a VE head?

Bump for these 2 guys...what about an ae111 itb setup on a VE?

To small. Waste of time. ...

The Martin Bruwer ITB's are supposedly quite affordable.


SR20DE.



SR20VE.



I would really like to try out ITB's, though it is the tuning that puts me off, as I would prefer to keep the stock ECU. Is it true that it is possible run ITB's with just a Greddy E-Manage Blue, or is that an urban myth?
A guide to tuning ITB's and the minimum requirements to run them would be great.

As far as i know, you can run Nismotronic ecu and it also converts to MAP
