You should replace them when you replace the clutch, which you should do.

Bti, may I make a suggestion, do all your homework before buying any TT or SC kit? Also, know that you should have $5-8k of "oh shít" money in case your engine goes

:iagree:

A spare ride or "bucket" may be in your best interest as well. Not having your car for a period of time can suck bad (if something takes your car down for some time). Otherwise, I suggest installing parts that perform well past your intended use to be "safe".

So Greddy had a rep talking about using Garrett Turbos at SEMA? I can't find anything on the GT-R kit or a future 370Z kit. This news makes me want to reconsider my plan to transplant my current 20G kit to another vehicle.

Is that a bad thing?

The rule on warranty with boost is assume it is gone.
If you have contacts at the dealership they might be able to help on a few things, but those are usually minor. Like a window motor breaks but the engine/tranny are gone, and they might work on the car but they will hesitate. Especially if they don't have a tech who knows or has done that type of work before since oil filter is relocated, oil levels are different, etc so they will not know these things and get confused.
