best bang for your buck!
my friend has pulse plugs in his G
and he noticed a pretty good mid range power gain
they dynoed a 350Z bone stock and got 11whp gain
i was like WOOOOOH how is that possible!?!?!?
lol
then i found out that it burns the fuel more fully than our STOCK plugs
ONLY 25 BUCKS A PLUG!
Iono about that, I looked into it because I heard good things, but there is a huge thread on here about the detonation that people have gotten, and how it's blown more than a dozen motors already. Pulse plugs at your own risk, don't wanna guarentee, but do your research b4 buying anything.

+1 on z-tube, pop charger, spacer, and sways! After that, learn to drive the thing lol!

But this car isn't easy to mod on a budget. Ebay parts for this car won't hold up for too long...
springs do nothing but prematurely wear the stock shocks. Intakes do nothing for performance on the G. A plenum spacer doesn't do much either. OP your first mod should be sway bars.

First mod? Your choice between a plenum spacer or sway bars. That's my opinion, at least. Those both yielded me noticeable gains, in their own way, of course.

Actually, even if the spacer isn't giving you horsepower, your a/f will be richer, so you should have better response, not to mention that your car will rev up faster.

i read somewhere that stock ecu on the g35s already tries to run the engine rich at a mid to high rpm with the only purpose for that was to slow down the rev up before redline so the revlimiter can be more easily avoided, so if the spacer makes it run even richer, then i would think that the engine would rev slower not faster, just an FYI for ya

get some clear corners and save the money. use it towards the car payments or give it to your parents if they're paying for it. better yet, if they're paying for it, use it on a nice a$$ xmas present for them.

I guess you read wrong. I test everything after I install it. And I've personally tested the different plenums, and spacers to see which makes more power - all in one day so the temps and all are the same and the numbers stay consistent.

Try it on a dyno. You'll see a difference. I would do it again since I have access to a dyno, but I'm not going to take my car apart, reset my ecu and all to get you a dyno number on this.

I may have read wrong if ur telling me that if increased ur out put, but can u b more specific on the type of a difference u experienced. Was the hp/trq higher and about how much. Was ur 1/4 mile time faster and how much. Just something for me to know before i commit to the upgrade. thanks
