I've gone for 1 vacuum source to power the brake booster so the very back runner has had a boss placed on the underside and its been tapped and a nipple (oo0oer) installed. This will run to the one-way valve on the brake booster line...no need to bother with the golden eagle vac tank I purchased....only $22 so no real bother.

The F20 cylinder head has a water jacket that runs behind the inlet manifold...and only a water outlet right at the very back (well...technically 2 as one goes to the heater matrix too). The back part of the manifold has had the boss tapped out to accomodate the water temp sensor that sits at the back of the stock manifold. The front of the manifold has also been tapped so we can get better water movement - its just waiting for the -3 union and fixings to arrive and then this will run back to the top of the water header tank .

Next job was to assemble the ITBs so the manifold can be dropped onto the motor in one piece. All o-rings on injectors re-checked and dropped into the fuel rail...each throttle body was then dropped onto the manfold and the linkages alligned (they will need to be balanced before mapping so no point in trying to do it now).

You'll also notice (or maybe not lol) the bolt-on water outlet has been cut off leaving only the boss. This is because the std item has 1 main outlet and another for the heater matrix...I have no need for such luxuries so its being replaced with a single flared outlet for the rad.



The throttle linkage on #2 itb also had to be modified - its slightly longer on 1 side and this would fowl the airbox if left. It was buzzed off and reshaped a little.



Next job was the airbox back plate, a template was made from the bolt holes on the manifold and drilled. The inlet holes could not be measured from the manifold as they taper down from the opening of the throttle body. The correct size holes were added and it was cut like so.





Next job was to bolt up the trumpets :smokin:



Inlet gasket dropped back onto the engine and the whole inlet assembly bolted up.



At this point I had a nice cup of tea and drooled for a bit :smokin:







Here is a rough idea of how low the engine is in the car - and the HUGE amount of scope for longer trumpets and airbox. If I go too long the ITG sausage I have to sit on the end will fowl the strut brace...I'm not so sure I need it anyway as the shell is much stiffer now anyway. Plus I still have the Nagisa turret to bulkhead braces installed and the sweeps-spec Gacchiri braces behind the wings.



I guess thats about it for now....iccle bit closer.
