So .... if I happen to be skilled at double-clutching and heel-and-toe rev-matching, then it does not put too much strain on the engine to use it as a brake by getting off the gas in anticipation as traffic situations change around me??? .... otherwise, I would have to stay on the gas until I immediately transition to the brake which does not make sense to me???
Thanks,
Thanks,

Hi Doug:
The key thing is NOT to back off the throttle from high revs in the lower gears as thats what really stretches the rod bolts and initiates the process. Such activities have cumulative effects.
Rev-matching, upshifting as necessary, and using the braking system to slow the car to the appropriate speed for the gear you are using, are the main things to remember.

Brake pads/rotors, etc are really far cheaper than engine parts,....

yeah.... I go through rotors and pads quicker than my 6-speed counterpart with my Tip.. who new my Tip could be beneficial in the fact that I don't 'engine brake' and can't overrev.....

Thanks for the replys. Sorry for going a bit off topic there Tom, that wasn't the intent.
I hope your car has a speedy recovery. If the $$ is there consider 3.8, it's probably the biggest power gain available for your car and now you have an excuse.

I considered the 3.8 (and many other performance options) for about a millisecond. It costs way to much and does not provide that much power. Not to mention that it puts me into a totally different race class where I don't want to be.
It will likely cost me $10k (plus or minus a couple k) to replace the engine and get a new one in with Carrillo rods and stronger valve springs. Throwing another $20k at it to go to a 3.8 is not what I want to do. I want a stock/prepared class engine that will last a few hundred hours before I have to do anything more to it (other than routine maintenance).
