How do you guys feel about ECU's? I mean theres a lot of great ecu out there has anyone try to get a ecu? like APex'i,Greddy, HKS??? like a AFEC's controller doesnt that help alot? I know it helps HONDA"s like there V-tec kicks in strong! but what about a VQ motor it should help it a lot too...i think what do you guys think?

 

"In general" I would say this statement is not true. Considering the cost limitations that Nissan has to adhere to in getting the vehicle out the door and making it competitively priced... there are many areas that can be and are improved by aftermarket mods. Nissan knows this. Exhaust, cats, intake and the list goes on. We are not talking a ferrari or porsche here; where you actually pay for the extensive research and quality up front.

 

Go with the TurboXS UTEC for the 350. Thats is my next poerformance mod. I personally don't think there is a better route than the UTEC.

 

or u can just put a 75 shot of nos.

 

And maybe blow up your motor at the same time.

 

^ you can blow up your motor alot more ways than NOS---

its safe if you know how to run it correctly.

 

those must have been some sh**y bolt ons and terrible tune. utec tuners can almost always get 10 to 15 whp on stock car. ive seen good N/A mods without cams get between 40 to 60 whp with a good tune. thats still not the 100whp your looking for but as bad as you make it out to be.

 

umm sort of.. just wanted get the general census in one thread.


on a side note.

Every Z is not created equal. i believe your power output changes by your driving habbit, amongst other factors (air temp etc.) for example, Aggressive driving expends more fuel and it'll affect your mods differently. When you first drive your z in a cold *** morning, the air is more dense and you'll feel more kick, oppose to a hot day. breathing mods should, theoritically, help you mpg, too.

 

I picked up 6mph with only 23 peak whp. I went from 13.7 @ 101 stock to 13.1 @ 107mph with bolt-ons, with around $2000 in mods. Id say bolt-ons ARE most def worth it, if you tune your Z AND learn to drive, if not you'll forever be high 13's and complain to others how much bolt-ons sucked....

 

when you do bolt ons you have to tune it to get maz results.

 

Alberto- What were your bolt-ons, exactly?

 

$350????Where???

 

i love your honest opinions. even after going F/I, bert doesnt let it get to his head and gives honest and insightfull information.

 

What are the advantages of this UTEC?

Thanks.

i think he meant 350 as in 350z

 

Thanks.

 

I've spent 1,200 and gotten exhaust/intake/plenum/TPs -- dunno where people get that its "so expensive". If I gain 25 whp from those mods (which is very possible...) then thats 1200 bucks for 25 whp. FI will get you about 125 whp for 6-8K. Seems to me to be about the same $$ per HP but on a lower scale.

 

You're proceeding from a false assumption here - that aftermarket tuners have a larger R&D budget than a multinational corporation. Nissan has a depth of engineering talent that the aftermarket (and Porsche and Ferrari for that matter) can't hope to match. Further, their supplier relationships and volume buys mean that they get top quality and low price. Even HKS and Greddy can't compete on that level.

I stand by my original statement. The rice boys who spend big money on intakes and exhausts, etc. learn these lessons the hard way. Believe me - they'll only do it once.

 

Wow it really has been a long day at work, I cant believe I missed that.

My bad Rob, my eyes arent working like they used to.

 

It is not always the highest horsepower that nissan is going for though. If nissan equipped every 350 with high flow cats, headers and a borla(just an example) exhaust they would not sell nearly as many cars. The engineers have to compromise because they want an exhaust that is civil enough to drive every day while still putting out good numbers.

Look at VW's new 2.0t, a simple tune bumps it from around 200/200 to 250/309 bhp. The older 1.8t went from 180/180 to about 230/245 and the factory downpipe goes from a 3" flange to a 1.25" bottleneck before expanding to the 2" exhaust. Don't even get me started on Ls1's either .

The bottom line is that Nissan also has to deal with emissions and tons of other regulations. So while nissan may employ the best engineers on the planet, it does not mean they use the extent of their knowledge on the Zed.

(P.S. sorry for my rant I wanted my first post to be something interesting)
