best place to inject alky on a hot air intake?

[TURBO E38]

I may like put on a alky kit on my Hot air Engine, the Intake manifold is stock , but I do not have a the small short adapter like on the 84-85 GN, but a 180 degree elbow that is on my 85 HOT AIR TURBO RIVIERA. THE intake manifold is idenical to the GN except my turbocharger is lower and further back towards the firewall and the compressor outlet points up towards the sky and the 180 degree elbow connects it to the intake manifold. it uses the same large and small o-rings as the short GN turbo to intake coupler.

REGARDS, TURBO E38
