Sigh ... repeat #3. PER THE FSM, while the car has 0 throttle (aka decellerating) and you are above 1,800 RPMs the car uses 0 gas. Once the car reaches below 1,800 then it resumes idle fuel usage. SO GET THIS PEOPLE ... It is MORE fuel efficient to be at 2.0K - 3.5K RPMs with no throttle then it is to take the car to neutral and slow completely with the brakes and place excessive wear on them. /thread

Funny, I never would have guessed that. That's definitely not the case with everything, I've noticed especially in drive-by-wire BMWs that they drastically reduce engine braking. I like engine braking, I'm glad the VQ30 lets itself do that.

There are some nifty cars out there that give you a liters/hour reading that is continuously updated. I think the USDM VWs and BMWs have this. It will show you where/how much the fuel is getting used.
I forget the numbers, but I'm willing to bet that the gas used to blip the throttle for a matched downshift (to get it in the engine braking/no fuel use zone) exceeds the amount of fuel if it were simply at idle.
In any case, we're talking peanuts. That's my point about the whole engine braking thing. No point doing all kind of fancy stuff to your engine and drivetrain to 'save' gas and 'save' brakes - the difference is scarcely measurable.

You'll love the 5 speed! I'm new and amazed at how quickly the good advice flows on this site, wish I would have found it a while back. The comments on the syncros and the TO bearing are right on, you'll get much more life out of the tranny as well as avoid the potential engine blow if the foot slips by not going into first until you're stopped/ready to go.
Hey ting...I'm planning to post a '96 5spd SE w/ only 69k miles in CA once I can reach my 15 posts without cluttering the board with cr#p. Keep your eye on the for sale board.
