I have a 2000 maxima gle automatic
I want to increase more power.
the mods I have is ebay catback and jwt intake

is the warspeed y pipe any good?

turbo or supercharged?

Warpspeed y pipe are (were) probably one of the most popular mods for good reason, they were cheap, easy, and freed up good power. I know on the 4th gens it was the best bang for your buck mod there was, im sure the 3.0 5th gens benefit the same way. Something like 15+ whp gains for a couple hundred bucks.

turbo or supercharged? There used to be plug and play supercharger kits for these cars, i think theres one for sale in the classifieds currently. Theyre very hard to come by since theyre from the early 2000s. Turbos on the other hand require a custom setup. They both have pros and cons to them, you can use good to look into that debate. In any case id say boosting is pretty far from simple lol

you might wish to learn how to drive stick, the manual trans on these cars is significantly faster than the autos are.

thanks im going to get that warspeed y pipe and a high Flow cat or a test pipe soon
is there any tune to run these mods for power because I seen ppl using a safc2 To tune them I want to get up to 200whp is it possible with the y pipe and hfc and a safc2? I already have the jwt intake and a catback

Bore out your precats also or get headers, and with the mods you listed + a piggyback tune you should definitely be in the ballpark of 200whp. You should check out the all motor subforum, its a bit ancient and dusty over there but theres tons of good info from back in the day regarding the setup youre looking to run.

For clarity, by piggyback i was referring to fuel controllers such as SAFC, VAFC2, etc. rather than stuff like e-manage, my fault. The latter would be total overkill for a build like this.

Supercharger is pretty easy to install and can still make decent power. Turbo makes more power due to efficiency but takes a bit more expertise to put together. The choice is yours.

so do I get a wideband and a safc2 tune the car?

if you are looking for a very basic and simple way to tune, yes, personally id recomend going that route. There are other more in depth ways to tune but in my personal opinion that should be good enough for your purposes. I actually have an apexi VAFC2 im selling, if your interested shoot me a pm.

Also i would do some research on the all-motor subforum before you make any moves, for example this thread;
https://maxima.org/forums/all-motor/...mt-6-7-eu.html
like dont just take my word for anything lol, you should always do some reading and make sure for yourself.

edit: wanted to add that along with your wideband you will also need a way to datalog. Most effective way would to buy Nissan Data Scan 2 and link your wideband controller to your laptop. Yet another thing you should read up on, its an awesome piece of software well worth the $60 pricetag.

What type of headers? You mean warpspeed y pipe or Obx headers?
Is the shift kit any better?

i really don't know how to install a piggyback or a wideband or tune a car don't I need to pay some performance shop to install it and dyno tune it?

does it the warpspeed y pipe delete the precats? Is it the warpspeed y pipe better then the obx headers???
