Default Re: Suzuki GSXR 750 quad Throttle Body Install on 2.3 L Duratec

There was enough wire in the Suzuki Fuel Injection Harness to connect a female plug (and a set of wires from a different plug) to the stock Suzuki Throttle position sensor. My tests showed that electrically the Ford and Suzuki TPS are very similar. The wires will need to reach the drivers side of the manifold which is pictured. They will be spliced into the Ford Harness with solder and then adhesive lined heatshrink leaving the Ford TPS plug available as well.
Copper pipe is for EGR. White nipple is for idle air feed. Slightly tan nipple right next to the wire harness will feed the MAP/IAT sensor or sensor Vacuum Accumulator (that would need to be made).
I did find a PCVfilter with 3/8 inch inlet and outlet from Vortech at Summitracing.com. This will be used to filter the crankcase feed which is behind the stock manifold into the idle air stream.
Also pictured is the throttle cam. Our Ford throttle cables are terminated with a ball connection. I will have to add a couple of balls to the Suzuki Throttle control hardware and may be able to get it to work with few changes. One outer ball for the cruise control one inner ball for the throttle pedal. With any luck we will Remove and Replace the stock manifold this Thursday and draw diagrams of the various gasket surfaces so I can fabricate the new intake manifold.

Height of this assembly to the throttle body edge is about 8.25 inch. It looks like it will fit with a short intake manifold. The EGR manifold and vacuum hose manifolds look like they will package neatly without interfering with the engine. They are also mostly invisible from the top view.

I have several components to mount. Two butterfly control solenoids. One Idle air Control Valve. I am thinking of adding a piece of brushed finish 1/4 inch T6 aluminum plate to the top of the manifold about 3 inches wide just to give me a mounting surface and also maybe to dress up the inner hose connections to the plastic manifold. The four throttle bodies will remain exposed.
