Performance Noob Questions
Hi everybody, first time poster... be gentle.
Anyways, I'm the proud owner of a '07 Sedan (Jade Sea Metallic, yeah yeah), have had it about 8 months, 10k miles on it, daily driver, yattah yattah. Love the car, love the gas mileage. My only quarrel has been accelerating from stop lights on freeway onramps to 65/70. Semi-truck drivers in So Cali aren't that forgiving. With that in mind, I don't have many plans or aspirations for my car other than to increase the low to mid range performance area ('cuz I like the 40ish mpgs I'm getting right now) and try to help out that acceleration issue. Shopping list thus far: Chino's intake (whenever it gets done) :D NST Pulley (heard great things) Custom Catback Exhaust* Header** 16" or 17" machine lipped wheels (still in the market, possibly Motegi's) HID (maybe) Brake upgrade (maybe) Whiiiiiich leads to my questions: *I hear everyone praising custom exhaust setups. My first question is what are the pros/cons of catback vs axleback? The TRD is axleback isn't it? : \ **The headers I've heard that were available were all 4-1. It's also my understanding this won't do much for low/mid range as opposed to a 4-2-1 header setup. Are there any 4-2-1 headers available for a sedan? Many thanks, Gary |

That's not a bad plan, I have the same problem here, I have to exit the neighborhood and merge into a single lane 80km/h road, and almost get rear-ended on a daily basis...
A catback will enable you to run high flow catalysers (or none, if you're feeling frisky), so overall giving you a less restrictive exhaust. And axleback only changes the muffler, so it's not as much of a help. So far, aftermarket exhausts are only axleback, but there's not a lot of choice for the sedan, which is why a custom solution is preferable. That's the theory with headers, 4-1 for better high-rpm power, 4-2-1 for a more balanced mid-range power. As far as we've seen, there are no aftermarket 4-2-1 designs available.

Definitely go for the NST pulley! It made a world of difference for my LB, and even helped my MPG by a bit too!

Yeahhh Gary!
I'm trying to get a response on when this aftermarket catback exhaust is going to come out, but no luck thus far. I'm hoping it wasn't scrapped. Custom is a good route to go, too. The only thing is CARB legality... ouch. |

By any chance do you know if this pulley will fit an 04 hatch?

Is the 2NZ the 1.3L? Shoot NST an e-mail to make sure, but if it is the 1.3L I think the same pulley works for either engine. He will be able to tell you.

hey, when you merge on the highway, keep it in 2nd till 60 then shift to 3rd... more power in higher rpms.

The best thing you can do for your car is to swap to some light wheels, get some better rubber, and lower it. Enhance your performance and your looks all at once.
And I agree with the NST pulley. Best $100 mod by far I asked Mike on AIM, NSTonAIM, he said they have already sold a few to 1.3 owners in southeast asia. Ask him on AIM or look through the NST discussion thread, the answer may be there.

Great! Thanks for all the replies. I think I have a better idea of what I'm going to end up doing.
Will order the nst pulley in the next week or so. As for the staying in 2nd comment, my car is an auto. :P My ultimate goals are to make this an ultimate commuter car: great mpg, stylish, comfortable, fun to drive. I've been looking for some lightweight wheels. So far the only thing that has really caught my eye are some motegi traklites: 17" that weigh around 14-15 lbs each. If anypone knows of a good brand that does the black with machined lip style I'm open to suggestions. And since we are on the topic of weight, are there any ways to get the weight reduced? I'm sure at some point there will be cf hoods and trunks. Any other methods or ideas? Sorry if this post comes out weird I'm posting from my phone. |
