I picked it up via 'gumtree'. Just a fluke really. Cost about $180
The wing stays were made up by a local engineer then fitted by myself. Took about two beers to complete.

the headers and y pipe fitted to the 2GR is one of the bottle necks, as is the plastic plenum with the variable runner setup. another thing to note is that the earlier 2GR motors had issues with ovaling the bores, leading to loss of comp and burning oil. Some of the earlier ones also had issues with the vvti cam gears flogging out.

The above are good points and that is why i talked Steve into using stock style throttles for ease of use (linkages that work out of the box for instance) this will give him less headaches and we all know Steve has had so many headaches i am suprised his head has not yet exploded :)
 
I know how much of a ba$tard it was to set up some EFI hardware gear on a BMW 6 cylinder...... The products are quality items though.

I ran 6 48mm ITB's on a 3.1litre stroked L series engine. You need to be quiet careful around the throttle body design and sizing as I used speed technology/efi hardware equipment with is quiet pricey however they run taffer bores etc...that create more power. Also and more importantly each throttle body had its own throttle stop as the twisting in the steel shaft is enough to through the idle out of balance. They are very sensitive I even had to change linkages to spherical ball type as the play in the cheaper linkages were also enough to through the sync out. I had to also run a custom main linkage that ramped at 40% initially before full to make the car perfectly drivable otherwise I wouldn't get enough throttle control. ITB's can be quiet fiddly to get right.

I really don't know how using stock style throttle bodies on a  ITB setup would work. Are they cable driven? Most factory throttle bodies are cable driven, so you would need to run a the main cable system to some kind of winch system to pull the throttles open?
One of the throttle bodies would need to have the TPS mounted on it where the others wont.
If you are leaving the injectors in the origional factory location and just getting ITB that are basically a buterfly, there are a lot of cheap custom made options for billet buterflys. They have individual throttle stops and are very compact, also have mounts for ram tubes. The EFI Hardware stuff has the injector tube moulded in as they are usually used for webber carb to EFI conversions, thats why they are pricey. Also mounting the injectors as far from the cylinders as possible gives better atomisation and gives better power.
