Rodney, i think the cattman headders for the 3.0 fit the 3.5, all that needs adjusting is the O2 wires i think.
i was supposed to ask. the 3.5 engine mounts on the same location as the 2.0? and are they the same mounts? i mean like size and shape and well of course the little sensors/motors in them  |
Is the cattman self i talkin bout!!! Dey havin a GB on maxima.org for this mth dread!!! An i eh hav no more friggin $$$ for now. The headers and y-pipe going for $799US. After it goin an be $850US.
I never saw the 2.0 mounts outside the engine, only from top. But i did se the 3.5 mounts, yeah is de same type with the sensors an sheit but it friggin huge dread. We not even botherin to disconnect it from the crossmember. we bolting up the whole crossmember with the engine.
Chiney if yuh want the 260km\h instrument cluster i may sell mines. Give u first preference. |

Also i can direct u to a site i came across today where a guy with a 2004 maxima with a 5sp AUTO with just an intake system and an upgraded ECU was dynoed to make 229HP, 231TQ. Also the exhaust headers i will be getting once i have funds will add "24-26 whp on a VQ35DE". So tell me why that's not possible.
Trust me i did my research on this!!! This eh no SR business we dealing with.
_________________ |
Have you ever actually done any tuning before? If you have, then you'd know that not everything that you read in the "mags" actually turns out to be rather practical.
Yes you can run a F/I kit on a VQ35DE. Sure it'll work I agree. Vortech has one. GReddy has a bolt on Turbo kit which uses stock internals. But did the mag review of which you speak, talk about how the car runs AFTER the install? long term testing? use as a daily driver? The stock internals were never intended for that kind of abuse. Take my car for example......injen makes a really nice CAI for it. GIves about 15 hp they say. And they are right....but did Injen speak about the downside to using a CAI on Scubie F/I engine? Nope. Did they speak of the risk of running lean due to improper MAF calibration? Nope. Remember, these companies are trying to SELL you their products...they aren't going to tell you the downsides to it.
Keep in mind that most mag articles do their testing on a track or something...but for a day or so. I'm talking about long term reliability & longevity of your engine
Second thing...when a manufacturer quotes a power gain on a car, that's the MAXIMUM possible. It does not mean that you'll acheive that.
Additionally, if you add an intake, which supposed to give 10 hp, and headers which supposed to give 25 hp.....adding both does NOT mean you will get 35 horsepower. Gains are not "simply" additive. They work in tandem with each other to produce an overall power increase. So if you add headers to your car, then the power gain from an intake may not be as noticeable, as if you had installed the intake on a stock car.
And if you expect to gain 70 whp on an intake, exhaust and headers, you're in for a rude awakening. |

Dread we tried to start it wednesday an we were not gettin any ignition(spark in no1 coil). But it did tumble!!! That's a good thing. The elec was tryin to trace back the ignition wire from the battery but he was not finding what he was lookin for in the wiring diagrams i have. So they were suppose to come back which they doing tomorrow. Project goin an start nex weekend an car goin in friday. So hopefully it may take a week as mech an elec workin during the week(full time jobs)
I goin an take some pics now an post up.
Chiney i would have the instrument cluster from my car to sell back. the A33 260km cluster. i no some of the A32 only came 180K. It's a one piece cluster that may need some splicing of wires to get it right. but it should work.
Knight, i understand what you saying but it's not from a mag i read what i read. I am talking from conversations from actual guys who did mods to there maxima's and posted their gains on a US forum, jus like how we posting here complete with dyno charts with their results.
I should point out some stats of the VQ. For starters, the VQ35 has a motorized TB. No accelerator cable an sheit. In the tuning nissan has built in mech to close the TB as much as 20% after 5000RPM's to force drivers to shift. So WOT does not mean u actually gettin the full power of the engine. The VQ's also run rich after 5500RPM. All of them, from the 2L to 3.5L again to force drivers to shift. They come with a 6500RPM redline.
Now the company doing the tuning has fixed the problem at WOT meaning no more TB closing on you so u gettin 100% power when u mash. Also they have brought the A/F ratio to a near flat line throught the RPM range(as can be verified by dyno charts of other maxima owners) and adjusted timing to match with an increased rev limit of 7200RPM. Mind you they are the only company that can do all of the above for the VQ engine. Not even JWT has done any tuning on nissans ECM's after 1999.
I should point out that there athe engine used in the USDM Maxima and the USDM 350Z are identical except for one is FWD and the other is RWD and yet the 350Z is rated as having as more than 20Hp more than the maxima Stock! Which suggests that from the factory the 350Z is tuned more aggressively.
And i know about the engines running lean after CAI installations. Actually the guy whose results i posted in prev posts was told by the company who did the ECM tuning to put back on his stock air box because he was running lean with his intake.
For the greater part of the year i have been researching the VQ engine and was originally not goin to do an engine swap jus a simple test an tune, so i knew what would've worked an not work. This is nissans new workhorse which has replaced the RB's and the new VQ35HR(stands for high rev high response) will be featured in the new skyline R35 with a twin turbo kit and cosworth heads with nissans VVL tech( from the SR20VE). Analyst's have said that the VQ35HR can stand up to 600HP FI on stock internals and on the turbo version can stand up to 1000HP.
And NO i have not done any tuning on engines. But any assistance i could get will be appreciated.  |

hmmmmm, wiring must be ah beyotch on that thing boi. sumthing bothering meh though. yuh know the keys have the lil chip in them, that the ecu reads, and if its matched to the engine it starts, if not it dosent start. it tumbles but dosent start. how alluh by-passing this or how alluh in cooperating it back back into the system?
ah next thing, why yuh doh source ah gearbox? that way u get more power to the ground and well, ah JDM A33 with ah gearbox aint exactly sumthing u see everyday 
when u run lean cuz of a modified intake, isnt it usually because the stock housing wasent reused?
a smaller housing would run u rich and a larger would run you lean, but reusing the stock housing should eliminate this. i was aware of this since i switched to a cone filter. mabey sumtime in the future i'll buy a rich lean meter and see what it says on my car.
so wah u doing bout brakes? i talk to W2J about the hawks, sounds like a good deal for when i'm changing pads next. i may put them on the front and back, not sure yet 
i eh doing no new rotors, wah was the price u had seen them for? landed here, in meh porch after all the customs and shipping and thing
piping for ah bess price stuck on the port. have meh holding back everything else.
chiney would u care to elaborate on the straps u used? where i could get them and where u fastened them to  |

Actually i got the NATS system from the car as well along with the key. So i jus have to re-program my current key to work with that system. About the intake, yeah when u doin CAI the only thing u really use back is the MAF housing, an i believe it's because the piping before an after the MAF is bigger resulting in more air comin in than the MAF was designed to read, that causes u to run lean. Not sure how much for the pads after shippin an all dat sheit. may be better to but it through W2J. Less headache. |

Interesting read! Well it seems that I was kinda on track.....to get the power you want from the FWD version...you would need to do some sort of ECU swap/retune/re-map, as this "company" has done.

Well this is something I agree with.....I did most of my "research" by talk to other folks in the US/UK who had acutally done ECU remaps, or used EMS-s....so the experiences they had, helped me decide if which route I wanted to go.
If you're going to get the most of that engine.....look at something along those lines. However, the problem would be to find someone who does tuning locally. Your car is a 2wd, so you can run dynos easy 
My 2c.....get the engine, along with headers, and any other mods you want installed...and then dyno and tune. Look at using the Turbo XS UTEC.  |

i placed the straps on ah bolt inside the bay.. no to far from the battery..
its ah normal black start.. nothing fancy. its jus neat.. thats all.
as for the cluster jed. i go hadda pass up on it.. lookin to get some new rims b4 yr end. thats another expense..
as for your swap..
GAWD DAMN!
since your engine its alrdy ah CAI...
make sure u get ah K&N drop-in...

Yeah my plan is to get the ECU re-map by the company( "technosquare" is the name of the company take a read: http://www.technosquareinc.com/maxima.htm ) to maximise stock power an then do modifications. Some people may say it's the other way around. But i also have a EMS to put into the car to cater for future mods So i thought of almost everything. |

^^^Well i have the springs but i don't think u could put aftermarket springs on yuh stock shocks. It's because i spent so much bringing in the damm thing that i eh get the shocks yet. Takin it in stages, to much to do in a short space of time.
I waiting for u guys to give me the final verdict on dem strut bars before i go an order up a set. Will definitely need it for dex an thing. |

the strut bars worth the investment. really helps with the body roll and understeering.
best bang for the buck!!!!
stillen has one for the rear i believe, and TSC on the forum has for the front.
the ones from stillen will cost about $150 US, IMO build it out of solid aluminum and make the brackets out of mild steel. it would cost u a max of $250 for the rear bar.
u using the tokico shocks and springs?
man all i have to tell yuh is GO STRONG cuz u in for sum headache and sum down time. when u get frustrated just go drink sum juice or sumthing
i will talk to W2J about the hawks(front and back) next time i go in to get the vent filter. would let u all know a definite price. he told me on average its $450 for the set for the front which isnt bad IMO. |

you should remap AFTER u do your mods....mods change the dynamics of teh car entirely...especially if you're going with headers. And it's best if you do a "custom" tune for your car specifically. |

^^ thats right.. its shud be the LAST LAST thingu do..
as for the strut.. it works great.. wen u swing ah corning fast.. the car stays level as even.. yuh do get that leaning on one side kinda sheit.. i real do it after i put she orn.. works real good..
i suggest u get something of great quality! |

padnah, i dont want to sound unencouraging, but a heavy, high torque, long, wide, front wheel vehicle may not be extremely competitive at dex.
it will be judged by its power output which will be considerable. but it's manouverability, and 2nd gear acceleration may be lacking in comparison with it's class counterparts. |

Exactly.
Your vehicles weight will work against you. Keep in mind that the Cefiro was built for luxury and a smooth ride...NOT performance. If you want a great handling car to AutoX / 'dex with then you defintitely should get REAL coilovers (like JIC, HKS, TEIN H-Flex, G-Control, K-Sport, MR....if they make these for your car that is)...and acutally play around with the damping settings to get the right feel for your car. Additionally, by using the coilover setup, you're ensuring that the spring and shock setup match each other.
But this isn't the only thing you'd need.....look at stronger and bigger sway bars. Also you would need to adjust your camber in the back (at least) to compensate for the rear end pushing out on high speed cornering..... |
