2007 350Z mods

[TheHat]

Looking to see if anyone had any ideas as to what 4 or 5 mods I should do to my Z without going FI. I had an FI car once and killed it and since I just bought myself this one I would prefer to keep it around a while even thought the motor supposeably can handle rediculus amounts of power. I know there isnt much out in terms of mods for the car but give me your suggestions you might no somthing I dont. Please dont be vague by giving me the same answers like headers, instead please be specific like borla headers.

Not many GOOD mods out yet for the engine. GReddy is the closest thing w/ a forced induction twin turbo kit but it hasnt hit the market yet. If ur lookin to add some REAL power (over 450-500 hp) id say to get your suspension & transmission ready 1st. You cant really go wrong w/ nismo parts plus they dont void your warranty, unless u go to anything R-spec. Check out PROcharger or APSturbo. They may not have anything but are more than likely working on it for the '07 350Z.

I would start with Jim Wolf cams to beef up the engine. Don't forget to replace the valve springs and shims. After that, I would drop a twin turbo which is a bolt on application from NISMO. I like short ram intakes and I believe AEM makes a nice one for your car. Try to find at least a 10 lb alluminum pulley. For exhaust, stillen makes decent headers and catback systems for the 350zs. Don't forget the tuning last. A good tune is important for the computer to recognize all the mods. Good luck!!

You sir know nothing and are the laughing stock of our forum. Don't give advice if you know nothing about what you are talking about.

There is no Nismo turbo out and no turbo is a simple "bolt on." You don't put a pulley on a turbo system, only on superchargers, you cant put an AEM intake on with a turbo system and the AEM intake is known to be the worst one for the Z to begin with, cams do very little for the Z and are the least cost effective mod to do to the Z, and you do not go in and do springs or other internal work unless you are making close to 400hp. You also do not use headers with a Twin Turbo setup and there are better headers than Stillens to begin with.

Do people feel a need to not pay attention to what this says about FI. It says I am NOT wanting to go FI. Besides the whole fact that its months old.

if u want power mods, get and exhaust and some test pipes or high flow cats. the test pipes are known to cause ur CEL to go on, and there is no know fix for the 07's. the nonfoulers worked for the 03-06, but usually provide less than a 1000 miles till ur CEL comes on again. some people are buying OBDII scanners so that they can clear the CEL every time it comes on.

technosquare is working on a reflash for the hr, according to the rumor's, they are almost done

all the suspension and wheels and brakes are the same as the previous year, so everything still works there

i heard a rumor that clutchmasters or centerforce was working on a clutch for the hr, but i don't know how reliable that info is

You may already know this, but I'll say it for the benefit of other people on the forum who might not. In a lot of states that do emissions inspections, if you clear your ECU too recently before the test, they will fail you. That is such an old trick even from the first days of OBD-II that they already caught on to. You might be better off with O2 "simulators" if you really want to go with test pipe. I can't imagine going to test pipes being worth all that much trouble without turbo's though, and you're keeping it NA. Maybe you want to focus on suspension and anything that lightens the body until you decide if you need more power? Some examples of O2 simulators:

Plans to make one if you are handy with very simple electronicshttp://www.mkiv.com/techarticl....html

As far as tuning or standalone ECU, there is a company that has adapted the AEM EMS to the VQ35DE and maybe they can do the same for the HR. Check out http://www.vqswap.com. They do get the factory CVTC working too. Again, as afar as inspections, the AEM unit does not support OBD-II so you're S.O.L. there too.

Thank you warm milk for your info on the latest rumor mills about stuff that is in development or going to be released soon for the HR. As far as the O2 problem that most have run into I got that fix when I threw on my HFCs. Definately going to be coming over to my350.

i don't know what "fix" ur talking about as there isn't a fix out there for the 07's yet other than clearing ur ecu every time the CEL goes on, but thats not really a fix

o2 sims have been tried on the 07 z and they failed, but thanks for the idea. about passing emissions, that wasn't really my concern, i would be more concerned about getting rid of an annoying light on my dash, and for passing emissions, u only need to do that every 2 years and for a new car u don't need to do it for the first 5 (in washington anyway). and by that time there will be a reflash that u can get that will clear the CEL for the test pipes

[TheHat]

I got my O2 sensor fix with HFC by putting on sensors from a 06 and my ECU never threw a code. I have been running my car that way now for about 4k now and still no codes or lights coming on to tell me that I have messed anything up. I have seen others running into problems but I guess I have just been lucky enough that my car doesnt car. As for emissions florida doesnt have any so its not somthing I am worried about.

[tollboothwilley]

you will find that Stillen makes some great products for this engine. cat-back exhaust(if you haven't done this) should be worth your time, as well as their intake, the MREV2 and plenum spacer. EverythingG35.com is a good place. Call and talk to JOE, who is a NICO member and has a lot of good input and will get you the best deal as well.

[samej82]

Has anyone tried procharger's kit for the HR 350Z? If so, how is it?

[R350Zz33]

how about the jwt popcharger first thing im gonna do

[irax]

On the HR motors the stock intake at the moment will make the most power.

and test pipes or hollow cats don't do anything except make your car louder and more polluting.

High flow carb legal cats at least give you the same 1 - 2 hp you would gain from no cats but still reduce polluting emissions like NOx

At this point an exhaust system, lighter wheels, good tires, and a good coilover setup will do more for than you think. Or at least wait for Techno Square to come out with a tune.

i put these on my buddies 07 350Z along with an Injen catback dual exhaust and stillen intakes. car has not had any CELS yet its been about 6 months now and a whole crap load of driving

[rmezz13]

u may wanna come over to

you may wanna watch saying that, and why wasn't this topic brought up in the 350z forum? there are plenty of 07-08's on there with plenty of mods.... so my question is WTF????

and for the record, good luck getting answers on my350.... that place must be read only because if you post anything, you get flamed or 21 questions about why you want to do it, or both! If you go over there, you'll see what i mean.

the twin-intake (correct me if you have the single intake "revvup" engine..but I thought hat was just a 2005.5 and 2006 thing) VQ engine is qujite efficient in it's design - I've only done a few things to my 2005 but the result is nothing short of impressive. With the new engine I'd go this route:

Nismo Intakes (essentially AEM dry-filter system but nicer looking IMO and won't freak out the warranty idiots)Nismo ExhaustNsimo Clutch and Flywheel

Those little bits alone will get you a few ponies and make it a lot more fun to drive, without voiding any warranty.

If you have money left over, grab a set of Eibach coilovers for some propperly tuned, street oriented fun. i'd also reccomend ditching the crappy BRidgestone OE tires as quickly as possible....they don't do the car any favors.

No one has mentioned it so far, but outside of the normal exhaust, suspension and tune, I would highly recommend looking at a good LSD and pairing it with a 3.9 FD. It makes the car get into it's power waaaay faster. Also, some people have mentioned intakes, but most of the intakes have actually lost power on the HR motors. Pretty much the only ones that don't lose power, are not gaining any power either.
