I honestly can't give you a good answer to that question. People claim to have noticed a difference when going from a ported TB to the 80mm, but I've seen no hard data. Will claims an 11hp gain from the 80mm, based on a 2013 impala going to an 80mm TB.

The manifold can be modified, we raise the floor for a 72mm TB for a smooth transition, it can all be ground/sanded out and the opening opened up to match the 80mm. You can certainly do it yourself, but if you wanted to send it in to us to do it, the cost is $90 with free return shipping for us to modify it (Most of the cost covers the return shipping as they're not exactly cheap to ship).

You'll have to contact Will about that, I know there is a 76mm option he offers, and I've heard there is an 80mm option that works, but the LFX 80mm kit we stock is not a direct bolt on to the LLT due to wiring/connector differences.
