GTM Performance Engineering: MHI Twin Turbo Official Release

370zrider

I am new in the forced induction subject... sorry for asking dumb questions, but I need to know the details of going TT.

Are stock spark plugs good enough to handle the twin turbo kit or is it necessary to upgrade them?

What is the additional maintenance the car must have once the twin turbo kit is installed?

You can run the stock plugs, but we usually recommend going with one-step colder plugs.

As for additional maintenance, there really isn't anything special needed just like a factory turbo car.

Before you get jumped, I would suggest searching within the forum for previous discussions of these topics, as well as checking out the various FI primer and FI noob threads.

To answer your question, you will want different spark plugs, and a well designed kit should not require substantially different maintenance than a normal sport car. However, you should plan on saving to fix things when they come up, and saving for more than just the price of the kit to do it right (e.g. gauges, cooling mods, etc).
