7A-FE ITB Project Options

[morag]

I'm Starting Individual throttle bodies project on the 7afe.I'll be putting CBR954RR throttle bodies witch have 40mm inlet on the vacuumed side witch line up fairly good with the Stock 7afe intake manifold. The throttle bodies go from 44mm on the trumpet side to 40mm in the vacuum, witch i think will make good air velocity for the stock FE head.
I intend to make a vacuum box to collect the vacuum from the ITB's and spread them in the bigger hoses for brake,map sensor,Fuel pressure regulator and etc(I have yet to figure out all the detail). I will be using 315cc Supra injector witch i've tested with the stock manifold(And it goes way rich).
What has been done so far is that I've cut the stock intake(Which i've got from the junkyard) and tomorrow i will see where exactly will they match up. I intend to use the stock 7afe injector fuel rail and mount the itb's after it. Tomorrow ITB lining and cutting a bit more if needed. Ah and forgot i will be using stock 7afe map sensor, TPS sensor and cbr1000rr manual idle air controller. If anybody is interested in this I'll be happy to see your opinion. I hope I make all clear tomorrow I'll make some good pics on all parts so far and all i intend to do . See how this works out.

the thing is that you don't need larger then 40mm throttles. cuz the port is small. i dont know how big are the BT itb's. but these cbr954rr throttles will give good velocity (will add) velocity stacks too)
