Dunno if I'd bother with the headers - they will be expensive to install and for the gains you'll get I'm not sure if its a good value for your money. A tune might be more appropriate....

ya i wouldn't do stillen headers or gen 3. for gen 3, u dont see gain until 7000 and u will need a tune otherwise your car is too lean. it is kinda dangerous imo.
however i would get fi long tube headers and fi catback tho. btw, when is ur z gonna be here? i think 40th anni is very very good looking. |

Intake, Header, HFC, CBE = Too Lean?
Fast Intentions exhaust and header comparison. Before and after UPRev tune (Dyno) Injen Intakes Installed! Pics, Vids, Dyno try talk to me after you done some research |

HKS over FI
Quote:
i've actually already read all those threads. I was considering getting the FI exhaust, but i think the HKS is the way to go after hearing it and speaking to a few local G owners who've gone down both roads. You're absolutely right about the CAI too, which i wont be going for anymore. |

Nope. It's Dave's.
I havn't considered not getting the headers. Are the stock good enough? Definitely getting a tune after everything though. Was thinking Dyno + UpRev ECM reflash http://www.ztune.ca/product.aspx?pro...3-0003ff2732c9 Last edited by Drexster; 03-27-2010 at 10:34 PM. |

i would still go for CAI if i am getting a tune along with it as well. it is just that it is not my top priority. test pipes and F.I cbe is my #1 priority now
If you are getting HKS, make sure you write a review and tell us how you feel! |

the car would only run lean if you change the intakes. you cant run lean just by having cbe and lth's. read the links i posted above.
It is about MAF sensors. Last edited by kevin.z; 03-28-2010 at 04:34 PM. Reason: i forgot to mention MAF sensors. |

What is lean? Lean is an AFR in the mid 14's or higher. For emissions and fuel consumption, I suspect this is where the Z is when it leaves the factory. The cruising speed AFR's will be lean in the 1500-4000 rpm range. For tuning, Afr's will need to be brought down in the fuel maps down to the mid 13's which is not lean especially for cruising speed. The engine will run cooler but be a bit poorer on gas. There is always a trade-off when seeking more performance! Getting into the 11's is too rich and in the 12's it's starting to get rich but these low AFR's are for WOT operation only which is a margin of safety that you won't run lean. I also haven't read anywhere that getting into lower AFR's requires open loop operation. If the O2 sensors are not being changed out then I guess they are wide band and will work fine for all usable AFR's in conjunction with a sufficient flow of fuel through the injectors. MAF sensors measure the mass of air (from this and air temperature, volume of air can be calculated within the ecu to adjust AFR) but it's the feedback from the O2 sensors into the ecu to correct the amount of fuel and air required for the target AFR. I play with the map schedules on my Harley because I have the tuning software to do it. Chemistry is chemistry when it comes to burning fuel and the bike follows the same principles as a car. So when I read about adding a cai and cbe, the car will run fine at the target AFR unless the injectors can't flow the required fuel. I don't see anyone changing to high flow injectors by just changing to cai and cbe and hfc's unless making 400hp or better from FI. All the tuner is doing is adjusting timing and increasing fuel where needed using feedback from the dyno. This can be done by seat of the pants or a canned map (provided you have the tuning software/hardware) which should get you close to what the tuner will do on the dyno provided the tuner knows what he is doing. Just like dynos, all tuners are not the same.

i cant explain this very well my self, but modshack has explained this better than i do. His expainlation is in the links i have posted above. It is dyno confirmed and proven that z will run too lean if u have full bolt-on and intakes (escpecially with aftermarket CAI). The optimal range for z is 12.6 to 13.2. Even Tony from FI has recommended not to go aftermarket CAI.
You should ask Modshack about MAF issues as i am not too technical in this. |

Nice drive is from Kelowna to Revelstoke, then to Nakusp soak in the hot springs then on through Cherryville to Vernon back to Kelowna. You have to cross two ferry's but that just adds to the trip, the twisty section back through Cherryville is awesome. Total trip is 500km or so, took about 10 hours with lot's of rest stops etc. Most fun driving I have ever had but I have only had my Z for two days, already put on 1000km on it

Drove the crows nest pass through EC Manning park this long weekend. Awesome drive with superb scenery and twisting winding roads. Continued along to Penticton then up to Kelowna. From there went south (2km before the kelowna bridge) onto Westside Rd. Which i have to say is really, truly amazing. Not only does it follow okanogan lake, is practically desolate of any traffic even Victoria day, but the combination of steep inclines and rapid turns makes for a true mountain road. There were a few nasty patches (pot holes, minor gravel etc) near the rural sections, but drive slow and you're good.
I then did a trial run in a friends car from Kamloops to Vancouver through Whistler on the 99. It was good highway for the most part, however sometime after Marble Canyon to Pemberton, near Fountain Valley I'd say the roads are inappropriate for a Z. Far too many pot holes and stretches of gravel. I would have cried if i was in my new car... Overall great weekend of driving! Planning on going to the island next time. |

If you can't find a good road in BC you haven't turned off the main road yet ;P The problem isn't finding a good place to drive its deciding which one of the multitude to pick
