How to get some low end power?

[quote=Unklejoe;7804783]100% correct. Most mods for the Maxima sacrifice low end power to gain top end power.
One mod that is good for low end power is NWP's intake spacer kit.[/quote]
Since he has a 5th gen with the plastic uim, would there really be any benefit?
I have considered it myself but have yet to see a dyno yield anything to speak of.

I was amazed with the low end torque my NWP spacers added. I would also like to voice my 
to NWP Spacers for this application (or for everyone with a 5.5 gen Maxima 
).

i think I'll consider this when i go back to replace my VC's in the next 25k miles, or so.
Or whenever the oil starts pooling in the spark plugs again.
Nice job Nissan!
Mental note: NEver buy a 1stgen MOTOR revision on a new car AGAIN!
gr
-1 on the turbo and Nitros. Those will NOT help low end.
Although it's been mentioned as the "do nothing" suggestion. I would expand to say no modification....but you SHOULD ensure your car is properly maintained (fuel filter replaced, change oil regular intervals, PCV valve, Platn. Plugs, and running 93+ Octane.
+1 on everything else mentioned. I would also add Aaron's (NWP) torque link. That should help put the power down.
Overall, you've got a lot of options. Just a question of cost. Opinions about what would be MOST effective or where to start is going to be individualized. But I would suggest starting on the basic stuff like maintenance, lighter wheels and components, and the torque brace....things to help cut the LOSS of power and the ability for the engine/transmission to get the power to the ground.

I like mine.
Make sure your knock sensor & MAF are working properly, I drove my friend's 2001 AE last weekend and it felt like it had 5x more low-end power than my car, and it had stock exhaust, stock airbox, stock VIAS assembly, compared to my short ram (reduces low-end power), header & cat-back, and gutted VIAS setup. Most breathing mods shift the powerband to the right, so +1 for the "do nothing".

The best way to add low end if your budget allows is supercharging. My GTP has GOBS of low end and mid range torque! And when I had the Eaton blower rebuilt, I also had it ported and installed a 3.4 in pulley which then destroyed my torque mounts

im lost... one says SRI, one says SRI reduces?
some of u are giving the dumbest suggestion, i seriously hope 3/4 of you arent serious.
take off the hood. ... and the trunk and seats.
...also the back seats, and doors and windows and ac.
and the headlights.
:/ long headers!!!!!!!!!!! super extra long headers!!!!

Read the whole thing please! An SRI such as JWT retaining the Helmholtz chamber, going with a HighFlow cat, and either retaining the stock bpipe or upgrading to a 2.5" bpipe only! While retaining the OEM (Trick/variable flow muffler) will enhance your lowend > to> Topend! I ran this setup for years and it's awesome, and it's crazy with Cattman headers.....You have super linear throttle response all over the rpm range.....I swear by it! This is why I haven't sold my 2.5" catback...If I ever get my GTECH to work on my new computer I'll be able to see how my previous setup (above) and my 3" Cattman catback compare....believe me it's doesn't sound modified until you put it to the floor or past 1/2 throttle......
sleeper + sum!!!!!!
sleeper + sum!!!!!!
Long tubed intakes seem to boost low and midrange power but suck @ higher rpms due to being to restrictive due to it's length..... most longer tubes make good low/mid range gains and most shorter tubes make better mid/high range gains.....But when a JWT 6" bellmouthed SRI is used in conjunction with the Helmholtz and Oem muffler the lowside is still linear and crisp.....play around with it....you'll see!

Isn't the Helmholtz the resonator box mounted right after the TB? I thought that design was more for a reduction in intake noise rather than airflow. I remember studying the Helmholtz years ago in a science class, I had to Google it to remember what it was exactly.
I'm guessing he's referring to what the OP will be doing immediately after spraying SeaFoam into his woman's uterus.
CMax03: Aren't people insisting in other threads here that the OEM cat is more efficient and less restrictive than the "high-flow" aftermarket variants? Someone suggested that Cattman's is the only one that is actually more free-flowing than stock. Further reading on the matter leads me to strongly suspect that those who feel catalytic converters are some massive, power-leeching piece of ancient technology haven't been informed of how different the modern three-stage cats are compared to their early 70s brethren that everyone seems to be familiar with.
If you have the money, I'd wager that replacing the cat with a NEW OEM cat would yield the same results as putting on a "high-flow" cat. The difference has to come from the fact that one is eight years and 1XX000 miles newer, right?
Can you explain anything else about the nifty "trick" muffler we've got? I've always wondered if Nissan chose components on our cars to aid in performance, even though most posters here seem aggravated that Nissan didn't put cheap 2010 performance technology onto their cars manufactured in the summer of 2001. Oops.
You can't sell a sports sedan without having anything "sports" on it, right? At least something has to be... Oh, wait... Yeah, you totally could.
