Try calling your insurance company and telling them what you are planning to do.Then report back with the name of the insurance company if they "don't much care". As the owner of an over-powered hot rod car ,I would love to know. You can get away with it on much older cars as 'agreed value/collector car/less than 3000milesper year type policies-as I do with full disclosure.But not on a regular insurance policy.
That means in effect you are uninsured if you do not declare complete details of the modification in writing to the Insurance Co.
Just google Insurance+disclosure material+fact,insurance fraud.

There are a few very specialized Insurance Brokers who do this work ,but they are very expensive.
It is misleading to suggest otherwise.
