I would use the cast aluminum piece that bolts onto the throttle body.

I don't think the TID would be the best place to inject. I don't think spraying preturbo is most efficient. You want to spray into the stream postturbo after it's actuallly heated the air via compression. I've currently got mine on the downwind end tank of my in, but I think the throttle body is the best place.

ie throttle body elbow.

TID will work, but may be the most difficult with all the stock equipment being there. You'd be mounting the nozzle in brittle plastic. Easiest will be post intercooler, pre-TB. Head over to the aux injection section and look for setups.

On a hot day, driving around town, my intake temps hit 135 just idling on the side of the road. When I hit 9PSI.... temp dropped to below 110!!

Isn't this fun?
