So I am fairly new to the car seen I just bought a 00 maxima se 5 speed
And I wanted to get some advice on how to get more Hp out of my vq30de-k
I know to start with full exhuast 2.5 inch headers with all cats deleted and 2.5 maybe 3 inch straight piped exhaust.
I want to net about 350 whp
Now the trick here is my girlfriend won't let me boost the car cause she feels like I'll get into to much trouble
So I want to see if its possible to get 350whp out of a vq30de-k all motor
Any advice on how to do this without boosting the car would be greatly appreciated

 

Wut

 

350hp, all motor...good luck with that.

Hope you have deep pockets too.

 

Someone posted similar thread a month ago

 

 

So if 350 seems to be unreasonable what do you think would be?

 

Buy a gen 5.5 with the vq35de engine

1. you will not get 350 hp

2. dump your gf

 

Good advice haha

 

You'd be lucky to break 250hp to 260hp... beyond that you're talking serious mods and money.

So if I do full 3 inch exhuast all emissions deleted ram cold air intake 500 to 600cc injectors and a walbro 255lph what's a estimated Hp gain from all thats

 

It's estimated you are heading in the right direction...absent a whole lot of associated mods and even more money.

No one can tell you ____ HP resulting from _____mods. Also depends on how it is tuned, other supporting mods, overall condition of engine and components, etc.

 

Might I also add that simply adding 600cc injectors and a walbro 255 will not really help much for a build that, well, isn't built. You'll just be dumping extra fuel into the engine that is not needed.

To achieve large gains on ANY build, there is a ton of research that must be done. You need to figure out exactly what is required from a very technical stand point for you to achieve the figures you're looking for. I won't even start on the costs of such builds.

Almost without fail, you cannot ever expect to gain a bunch of power by simply doing bolt on and inexpensive mods. Bolt ons will help for sure but doing an intake, headers, exhaust, and a few NWP bits is not going to have you pushing an extra 100hp. It will help the efficiency of the way that the air flows through the engine and can definitely help gain some power, especially if you take the time, unlike most, to go get your car tuned properly after installing them.

What you're looking for is not easy, or cheap, especially considering that you are starting with the VQ30 where you have ~150+ hp to gain before getting close to your goal.

The members on this forum will be happy to help guide you along your journey, but in the end, it's YOUR journey and you have to prepare yourself for it. Without proper preparation and research, your "goals" are just dreams, and preparation doesn't include going on a forum asking how much horsepower you will make by installing one mod or another.

If that was a bit harsh at all or you took offense to it, welcome to the internet, if you can gather what I'm carrying on about, then hopefully you can find the drive to set your mind to what it is that you want and go find a way to make it happen.

 

Adding more fuel will not net hp in fact fuel consumption will drop a good amount on city.
Enrichment from the stoichiometric ratio will just be a waste aside that most never tune their final product due to insufficient funds'
The most beneficial method is going standalone to feel any kind of improvement right off.
And since I dont think you have much understanding of tuning a combustion engine on your own, you probably are out of luck sir

 

I'm pretty sure you need some kind of engine management unit like a Haltech or Emanage as well... But the fuel pump and injectors might be overkill

 

DEK isnt the bust starting platform really, if you have deep pockets you can prolly get it to 260whp like Moncef did with his fully built car. That goes back to the saying deep pockets, fully building one should be around 8k in motor and exhaust work prolly. Maybe even more then that..

enjoy...

Why was his engine moving so much in video #1?

 

cause a engine is made of moving pats??


called torque bud

 

Crap mounts.

My car will twist before my engine does.
ES bushings and 94a side mounts.

 

I keep waiting for threads to start about cross members cracking/breaking like they did in the 3rd gens. Maybe the torque mount in the 5/5.5 gens help resolve that issue.... perhaps.

 

Kinda sad but true..we cant even get 280whp out of a V6 when Hondas can build a 4cylnder all motor push 290whp under $3000

 

It really it kinda sad considering the money you would have to spend to get that out of a vq30
