looking for more OOMPH.....what next
i have a 2001 z06 and i have a haltech CF intake and a B&B PRT exhaust. As far as my next mod goes im looking to spend around $1000 and want the most gain for the buck. I know cams are very popular and give alot of gain, but im not ready to open up the engine just yet. i also have a honda s2000 that is my track/weekend car and recently i changed the rear end to a higher gear (11% change) and it has made the car much more responsive and better matched towards my driving style. this made me think about doing the same thing to the Z. 6th gear isnt useful even on the freeway and the gears would give me more pull in every gear. Is this a typical mod for our cars or is there something else i should be looking at? thanks.

looking around it seems that i can go up to as high as 4.10. what is the stock rate? i would assume 3.90 would be the best compermise, i put the 4.56 gears in my s2000 and 4.10 is stock, im just wondering how much of a reduction the 3.90's are. Also it looks like its about $1200 for the gears, would install be just a simple swap or is there anything special needed in terms of the install, Finally what do you guys do to adjust the speedo? i have a "yellow box" in my s2000, will the z06 require the same thing? thanks.

I have 295 rears toyo t1r's and first isnt that useful but will i really be losing traction in 2nd? the point i want to address is i want 3rd and 4th pull thats why im looking at gears because it made such a difference in my s2000. what is the stock gear ratio, i might pick a conservative upgrade of 10-15% as i did with the s2k(11% reduction), and it made it perfect.

screw the gears, more traction problems, less mpg and that much trickier to pilot. Definitely go with long tubes. You'll get your extra oomph and driving the car will be the same, and same low rpm's for highway cruising.

from everything i have heard the headers dont give much bang for the buck. i was looking at a site and they referred to headers as "For those who are looking for that last bit of power at any cost" as for MPH i drive the car on the freeway in 5th all the time because it has no pull in 6th even at 90mph. If i was to do headers what about finishing it off with test pipes rather than the cat and then use sparkplug de-foulers to trip the computer so i wont get a CEL.

Throw in some long tube headers (can get a nice used set for around $500.00 if your patient) and the awesome LGM G5X3 cam and cam upgrade valvetrain package, dyno tune it, and call it a day, as you will be making around 425rwhp on your stock heads!
IF you don't want to touch the motors i put on 4.10s on my old 03 Yellow Z, and that baby was a little rocket ship, altough traction was useless without drag radials on the street!!

I didnt really want to open the engine up yet, i know cams are the way to go however i wanted to keep my tuning to bolt ons at the moment. what if i went to a milder gear setup like something around 4.50-4.70? i dont mind if i dont have much 1st gear but i want 2nd to hook up for the most part, ill probally go with the headers if you can get them for 500-700. with these headers will i not have a stock cat anymore (i dont mind, i just need to be able to switch back eventually to pass smog) thanks for the help.

As far as traction on the street, a stock Z has issues and if you are in it that deep, well take it to the track, and be safe.
Mods on a Z is never ending and I would advise you to think it out step by step. You can do gears if you can swap it yourself (not too hard) and be under your 1k$. Header are a great mod IMO, and the LG Pros are awesome and I know from my car, the gains are there. I dropped .4 at the track and gained almost 4 MPh (with a tune). They make the car sound so much better and you can keep CATs on for inspection. Good headers will realy wake it up for you and it is not that hard to do yourself too if you have space tools and time.
BLUFF headers brother, you will not be disappointed
