anyone done this?



im just looking for an estimated power increase over the stock manifold set up from someone whos had experience with these, or something similar.

You can make stupid power with ITB's, but you also need a huge port to use them effectively.



If I ever build another NA it will be a 13B in an FD with ITB's and a Nasty Port.



All you need to run them is a fuel computer, not a full stand alone, unless you use an FC ignition system.

i using the apexi-PFC full stand alone. and im going with a half bridge port. oh and the turbo is a Precision T60-1. wich im now thinking of going bigger, but i hate lag. for now i already have that one.



im just wondering if the set up is worth the 1200 dollars. minus what i can sell the stock manifolds for with block off plates and the greddy elbow. if i'll only gain like 20-30 WHP, then i'll stick with stock...

anyone have any pics of the entire setup...

go to tweakit.net



are the links not working???

The links work, but there are no pics installed on an RX-7.



It looks just like a Weber, or IDA set up carbed, but there is a rail and a few wires.



You wouldn't want or need to use the Power FC on this kind of set up. A fuel only computer with a 12A dizzy would be reliable and easy to set up.

to get full potenial of this set up. a stand alone would be best. and having a half bridge, larger injectors, single turbo and others.....stand alone is the only way to go.



i havnt seen this exact set up installed. but its pretty identical to any IDA/ITB set up on any 13b/12a set up.



but what im really interested in is the power potential, and just how much potential is accually there...

Not worth it for a turbo application. The ITBs can help to make more power in a normally aspirated situation if the rest of the intake manifold etc is properly designed and engineered.

No way is it worth $1200, don't bother with ITB's unless you're going n/a. The main advantage by far of itb's is the throttle response - completely pointless when you've a turbo.



Woops I should really read all the posts before I go and say something that's already been said!
