I want to improve the performance of my 06 Z, If you gone to mod your car performance what are the first 3 mods you will do? Im already put a drop in K&N filter in the OEM box. But i don't know if i go with HFC or Headers as the second mod...

 

Id go with Motordyne 5/16" plenum spacer, then exhaust. Thats it for me as of right now, cant complain!

 

i got my pop charger, next is spacer, and then probably exhaust.

 

Plenum spacer and a nice exhaust system; Nismo, HKS, Fujitsubo

 

i did headers, hfc, and exhaust. then got rid of everything cause i went turbo.

 

I would use the search function and see that this topic has been posted multiple times before.

 

What the hell, I'm confused. I thought that plenum spacers are NOT that great for rev-ups?? Or is that the MREV(+,2)? Or am I just confused?

 

IME pee works better than water as an engine coolant and can easily bump up 5hp from just peeing in your radiator a few times. If you poke holes in your catalytic converters that will also help release some backpressure in your exhaust that robs your engine of hp. I know you want engine mods but also if you fill up your tires with helium it will also reduce your overall weight and also unsprung rotational weight which is always a killer performance mod. Toulene mixed with rubbing alcohol and everclear will make one hell of a gasoline additive. Don't worry about ratios just mix it up and you're good.

Hope that helps.

 

now you are getting the hang of things.

 

The first mods ppl usually do are twin turbo, then chrome wheels, and then hydraulics to make your car hop as your twin turbos are boostin'...geez..dontcha know!?

 

 

Don't forget to bleed the air out of the system when you're done. You'll have LOTS of bubbles if you go this route.

 

how much do you want to spend. your first mod can be an $80 filter upgrade to $7500 for an APS twin turbo. What is your budget?

 

Spacer doesn't do much, if anything, on an '06

 

I wouldn't be too worried about the exhaust, the stock exhaust is pretty efficient as well as the stock airbox. Also from my understanding spacers for our revup motors have very minimal, if any, gains. Don't get me wrong, i love to mod my car and hate to have anything stock but IMO the HP/$ ratio on boltons isn't that great. But if you are just itching to do something to your 06 and not looking/have the budget to go f/i, go with the tried and true first mods: JWT Popcharger, MD spacer(little gains, if any but for sh.its and giggles why not), and a form of test pipe/HFC from either Labree, APS, or Crawford. Sorry for the misspellings and unstructured response but im DEAD tired and have work in the mourning.

Edit: Don't expect to much gains from these mods. Also to elaborate more on the lack of gains from spacers, it is mainly due to the fact that nissan apparently fixed the front 2 cylinder starvation problem on the newer generation VQ's. But the MD spacer does however does seem to lower the plenum temp.

 

^ you have enlightened me haha

Threadstarter: for an '06 model my 1st 3 mods would be 1st an intake (i got the Injen), mod after that probably a full exhaust system....and well after that i think that all the other mods are a waste of money besides going F/I for an '06, i would think maybe a reflash but with only 2 bolt-ons i don't think it would make much of a difference.

 

You could try some good weight reduction. The Z needs it.

 

wow im glad i joined this site when it was fiarly new without the hositility
