correct me if i'm worng, but i think it's where they squirt fuel directly into the turbo to keep it on boost

i think you need special turbo's for this too

I thought the fuel goes into the turbo exhaust housing/manifold, and you need a turbo with a Maram/Marram shaft if you want your turbo to last more than a day or two. And it's supposed to be really really noisy.

But I certainly ain't the expert

anti lag is an ECU controlled thing it retards the ignition timing to basically turn the engine into a giant flame thrower by igniting a very rich mixture just when the exhaust valves are opening thus keepin the turbo spinning up nice and fast.

However for this you will need a stronger turbo, ALS controll unit and a some very expencive ways of keeping the engine cool as manifolds running anti lag have been known to reach 1100c
