I want to making the engine more resposive

I have a 2001 Maxima Anniversary Edition with 236,000 miles. It is a very strong engine, I would like to know how to make the engine more responsive. Currently when I step on the accelerator the engine doesn't come back to idle very quickly. My machinic says its because of the programing in the ECU. Do I need to invest in a performance tuner?

Get a lightweight flywheel? Im not exactly sure what you are going for with “responsiveness” but if you want power, you do that with more air, more fuel, and a larger exhaust. Unfortunately those all cost money and for the 3.0 the benefits are nothing special. Not to mention 200k+ miles is pretty up there to start spending money on mods.

Your best bet if you are dead set on modding is probably to get a max with lower miles and one that has the 3.5L motor. Or maybe swapping one into the max you have now? In any case id recomend against putting lots of money into a car with as many miles as yours, it surely has life left being a VQ but over 200k is still a lot.

You could do things that make it feel snappy like solid motor mounts, engine braces, stiffer struts, etc. It's not going to get alot faster but it will feel better when you get on the gas.

I don't agree with slamrod in one sense-200k is only half life if it had been maintained. 400k+ went on my first max before it rusted out. However he is right saying that as that is too many miles to make an engine work harder than designed.

A lightweight flywheel won't do much on the 3.0 liter cars like they do on the 3.5. Also, they're expensive and install is a LOT of work.

The 3.0 liter cars respond well to an aftermarket Y-pipe. That seems to be a good "bang for the buck" on those cars.

It really depends on your budget and if you're the one doing the work.

You could start by upgrading to a maxima with about 1/3 the amount of miles...
