300 is just a number, get basic bolts-ons and a quality tune and be happy with the outcome. You'll see more of an improve in performance if you upgrade your suspension versus spending that money for an extra 20hp from headers/cams/etc to hit an arbitrary number.

 

I agree with all of y'all ^ I wouldn't run nitrous at all tho but that's just me, and if you run a Godspeed turbo at least get a garret turbo or another trustworthy company, you can pick up stillen and vortech kits all day long for 3000ish and be well within your 5k budget even if you hit any hiccups but n/a and budget don't usually go in the same sentence, it can be done if you are patient and watch the forums and buy used but most people arnt to patient lol

 

300hp with NA is not worth 5g's. Better just spending extra 2 to 3 grand and get a turbo or SC. Reliability will depend on the tune.

 

After you spend the 5k & get the whp to 300+, what then?

 

I can beat my dad's 911 turbo lol

 

Good luck. My money is on the 911 turbo

 

you have alot to learn............ ALOT, 300 hp is going to have same/similar stresses be it na, fi, or nitrous its physics. f=ma, you go fi your increasing the mass by making a bigger boom, go na and you are increasing a through increased rpms(and likely m as well some due to supporting mods increasing airflow) in the end both will provide you with the same F and the same likelihood of breaking something.

saying if you did go one of those routes and picking a supercharger while easy to hit is contrary to your line of thinking as well, since 300whp on a supercharger is actually going to be quite a bit more then that, figure about 320-330ish since the supercharger takes more power to spin. all things equal, at the same power level the supercharger will have greater wear and more likely hood to break something then the other options.

now regardless of what way you go thats a relatively safe goal for the stock engine if you have a good tune, nitrous is prob gona be the cheapest though but have to refill the bottle.

 

I always thought a supercharger was more safe because of the operating temperatures but i did the research and found out that is not always true. I wanted to stay away from FI. I guess a turbo would be best then, his car is turbocharged but it would of been a lot sweeter knowing I beat a 911 turbo or at least keep up with one with a NA 350Z.

 

I wish I was a mod!

 

nah even at best a supercharger is only going to match a turbos efficiency and produce the same intake temps, but draw much more power in the process.

 

used vortech maybe?

 

I would just find a used Vortech system. With a good tune you will have a reliable 400rwhp.

 

I'm with you... you're not beating a 911 turbo (996 or greater) with 300whp in a 350z. Hell, you might not beat a 911 turbo (996 or greater) with 400-500whp in a 350z... At least not from a dead stop.

 

Better off learning on how to beat the driver. I outrun many faster cars at the track.

 

That will not work. He's got a lot more experience than me and even if he did mess up his car's power will make up for any mistakes if he raced me. I think I might turbo my car instead and raise my budget limit. I've driven his car before and I know for a fact I will never beat him from a standing start even if I was Mario Andretti and had racing slicks. 400rwhp it is. I've been looking into a rear mounted turbo setup from sts. I also don't want a loud blow off valve and a huge intercooler where it's obvious the car is heavily modified. I want to keep it quiet and incognito so he thinks all I did was just get throw on basic mods and some nice tires to beat him.

 

you can always paint the ic flat black,and recirculate the bov,no need to move everything back,good luck with the 911..

 

Most road course events are not standing start, unless you do monkey racing.

 

After reading this. I'm guessing this is your first car? Maybe your first car you could mod. You really need to do alot of research before you go F/I or any type of mod for that matter. You trying to beat him in a straight line or on a track? If its track, spend money on sways, coils, and tires. If its in a straight line you'll never beat a 911 Turbo. Unless you get a built engine and twins and even then you are probably going to struggle from a stop. A Z is a torquey car from factory.

Personally if I had 5K extra, I would spend money on suspension and then spend money on HP mods. You'll have a WAY easier time beating him on a track versus a drag strip.

 

+1 I agree that you ned to do a lot of research. Try a track day with the car stock and go from there. Don't just throw parts at it and hope it will make it go faster.

 

300whp on a DE would be hard for $5k. Here's my 2007 HR story to achieve 301whp:

Stock dyno- 254whp

Injen CAI's
Tomei V-II headers ( yes, they do fit the HR )
Tomei test pipes
Tomei cams, 264 in and out
HKS HighPower exhaust
Cobb AP custom tune

End result- 301whp. After that I put in the 4.08 FD and the butt dyno showed a much bigger gain than the 50whp increase for alot less money.

Like most people, it wasn't enough. I ended up stroking and boosting it. Now it's close to 700whp.
