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.

QUOTE (morag @ Feb 5, 2012 - 3:33 AM)  and guys what that vacuum line for coming from the valve cover next to the PCV valve and going to the intake? those are breather tubes, they can go into a catch can with filters. What are you tuning with? Nothing right now, you'll probably want a stand-alone. Where is your MAP sensor reading vacuum from? You should have it on a small bottle so it has a steadier source, each intake pulse is probably screwing with the reading. How bad does vacuum bounce around at it? How much does it's voltage fluctuate How much vacuum are you pulling in your 'bottle'? Is it steady vacuum? You should really have two bottles. One small one for the MAP sensor (assuming it has steady vacuum) and another for accessories with a check valve to hold vac at higher throttle so the brake booster etc have steady vacuum source.
