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.

Sounds freaking awesome man!

Pet Peeve... witch=which.

Good luck with your build!

but the steep angle of the ports inside the head will pretty much road block that scavenging effect, don't you think?

I don't think so. In fact i think steep angle is really better for making power nearly all modern engines have steep angles, F1 cars have even narrower head design ( And they too use ITB's) Hayabusa has a very close valve angle to the 7a/4a - fe engines. We'll see.

Are you going to atleast run some longer duration cams?

dude that thing is going to be freaking loud!!!!!

Will need pics/videos.

This is a low budget build so no cam's YET.I'm planning alot of things but we'll see.Im grinding the intake manifold tubes so that the itb's can fit good.hopefully i'll mount them today and make some pics.

here's whats up so far.next step TPS sensor plate and vacuum box

can see images ?

Thats gonna look bada$$

so m8's here's the progress ITB's are rdy and will be mounted tomorrow to hear it ROAR


Here's the TPS sensor plate that i made my self.If you want to do it this way you need to put the plate exacly the same way for the tps to match to bolts(You need to make tps holes a bit bigger)

I placed the vacuums in the existing injetor holes in the itb cuz i wont be using them. makes a good vacuum for brakes and things


Here it is from above. the full thing


Ah and now the good staff a vacuum tank .Cuz i said this is realy low budget build it's homemade from a pvc pipe it seals realy nice.


i will be glad to see what you thing i'll upload a video of the first start of the car. Next thing new cams and high compression pistons

i've always wanted to this. there are ITB's available here from 4AGE BT. watch mode.

keep post sir.

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)

I bet that will sound real good when its done

please get a better camera

Low budget build... has to be documented with a low budget camera too!

Hell my phone takes better pics than that

Lookin good. Cant wait for a vid/sound clip once its running

It's actualy a phone camera .And the thing is mounted. I encountered alot of problems especialy throttle cable...but ill make it today and make a video

curious to see how well this will work, and how much (if any) HP this will give the lil 7A.. i know that you are doing this on a low budget, but if you had a way of tuning the car (like a greddy ultimate e-manage)b4 and after to maximize the effects of any gains the ITB's would give.. either way.. good luck.
