Your Top 5 Cost Effective Performance Mods.
If you are looking for relatively inexpensive mods for power, the best thing to do is help your Z breathe better. Meaning some form of cold air intake, replacement plenum such as a Crawford, or even more cost effective a good Motordyne plenum spacer would be the best bet, then a full cat back exhaust. Some people run aftermarket headers, however I have heard conflicting info on their advantages on our cars. Test pipes are nice too but they make the car loud as hell. I personally have the K&N intake and Nismo exhaust. Im working on getting a Motordyne 5/16 plenum spacer. So, to reiterate, here's what I recommend.
#1 Cold Air Intake (on average $250-$300 for a good one)
#2 Plenum Spacer (Motordyne 5/16 $265)
#3 Cat-back Exhaust System (wide range of prices from about $700 all the way up to $2,000 or more)
To give you an idea of what power increases you could get from this I’ve broken it down with specific examples.
Nismo exhaust ($1200) about 12HP at the crank or so (6.5 at the wheels)
Injen SP1986 intake ($300 or so) a max of 17HP at the crank
Motordyne 5/16 spacer ($265) a max of 13HP at the crank.
So for about $1700 you can get about 42 or more HP out of the car. That’s about $40 per horsepower.
For a comparison a Vortech s/c kit is about $5500 and gives you a max of 125 additional horsepower. Thats about $44 per horsepower.

The search function is terrible.

My first change used just conventional. Then I went through nearly all of it in 3000 miles. I am on Synthetic now and will shortly see what the results are. I am approaching the 1000 mile mark since the changeover.

Pretty pathetic when the moderator is losing his cool. He/She should be posting relevant links to threads.

Now IF danielwebb had posted a string of new and innovative questions that had not been posed before in some way, shape or form, I would say good for him for trying to learn something about his car. The fact of the matter however is that the questions he has asked HAVE been answered...numerous times in fact over the past 4 years.
When people tell him to search, it's not rude...what's rude is ignoring the the suggestions of veteran users, and continuing to fill the forum with useless threads that could have been avoided had he spent a few moments of non-laziness to search.
1) Given links to relevant posts
2) Answer the question
3) Just ignore the post

the search tool is perfectly fine. The problem is the tool behind the computer who is too lazy to use it or use it correctly.
idiot.

1) Given links to relevant posts

The problem with guys like the OP is that they refuse to search, and pose questions that have been asked over and over. He complains that there are too many irrelevent links in all the sub-forums...that's definately true, but they are there because there are others like him that keep asking questions that have been answered dozens of times before and fill up our forum with worthless information. It's not a question of "if you spent the same time and energy, you could have anwered his question easily"...it's the point of trying to prevent this dude from doing the same thing over and over and over and over again. For example, just search for "popcharger" and you'll see about 11 pages of people asking the questions that have already been posed.
I swear it feels like some of you are like retarded little kids that keep touching the stove, knowing you'll get burned.
technically you are going to get more for your money with any kind of turbo. You can spend thousands on bolt on's and only achieve maybe 20whp. Dont waste money on them because you wont get much of a difference from stock. Save your money for awhile then go FI.
To those idiots who said he shouldn't have to search, you're breaking a TOU rule:
7.) SEARCH FUNCTION
Please use the search function before posting or asking a question. It is a much more efficient and quicker way of getting your question answered. Another reason is to reduce the amount of duplicate posts and to conserve some server space.
