boi i know its over-kill, way over kill.
but this is what happened, i priced hoses and the low pressure hoses were a little cheaper than the boost hoses, so i bought the boost hoses, i never liked screw clamps cuz they cut into what they hold. u should see my K&N flange, its disfigured cuz of the screw type clamp. i not going through that again, thats the main reason i bought the t-bolt clamps.

as for the AC well i kind ah figured it was the air in the system, just wasent sure.

after the intake is finished i done with that car, nothing else i doing to it. Exclamation

hmmmmm, well ah do ah check up. all material comes up to $930. that is:
2 straight 3" couplers
1 straight 3"-2.75" coupler
1 K&N 5/8" flange vent filter
6 3" t-bolt clamps
1 2.75" t-bolt clamps
1 45* 3"diameter aluminum length of pipe
1 90* 3"diameter aluminum length of pipe

and well after ah lil labor cost, well it should be ah square grand or ah lil more.
so that eh all that bad considering the fact that is not the easiest intake to build #Fist

aye aye aye doh rub it in Embarassed

hear wah. what did u use to support the intake? like brackets or placement?

i got to figure out something, if i could figure that out i'll do it myself. only thing other then that is gutting in the vacuum lines. i still dont know how i geting it to work, cuz i have to put it 2 small tiny hoses, that go to the variable intake thing.

^^The VQ35DE FWD does 265 bhp.

And do you have any idea how much it's gonna cost to turbo that engine....at a respectable boost (and by that I mean at least 7-8 psi )????????

No mango tree turbo kit here man. Reday made turbo kits cost serious dinero. And if you're going to do a custom one, what about engine management? Internals? Drivetrain upgrades? etc etc....

boosting that engine not all that hard. if going custom built. it going to cost, but it not hard, just time consuming. 12psi max, and i doubt u'd need aftermarket internals. if u going N/A that basics could help. exhaust, intake, headders, some tuning with that e manage ultimate, port and polish.


looking froward to seeing it at the track, on the road, or mabey even popping the hood to take ah peek Mr. Green Mr. Green

chiney, thanks for the advice. Wink

How do you figure that? The N/A internals were never intended for elevated temperatures and other demands of a boosted application.

It can be done, but what about engine reliability, and longevity? Not because you read about a Vortech S/C kit for the VQ35DE in a mag, means that your engine will last long running it as a daily driver.....

265 WHeel horsepower = approx 330 crank horsepower. If you're prepared to spend some serious money, then yeah, sure I suppose it can be done. But dropping in simple upgrades like a cone intake and an exhaust aren't going to add 65 bhp just like that. An upgraded ECU, along with a manual transmission (auto tranny may not last under 265 bhp at the wheels), is more inline with what you'll need to do to bring that power on.

i hear what u saying about the boosting on stock internals. reading just one article on it was enought to turn me away from it.

I beg to differ since many companies have bolt on twin turbo kits for the350Z that does not need any internal mods. 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.

if i pop my engine is that self i putting in. (turbo of course)


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 Question

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.

_________________


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.

rodney, wah is the latest with yuh project? soooo long yuh saying it happening, i leaving the country soon, i wah see it b4 i go. hurry up nah!!!!!! Mr. Green


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. Smile

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 Twisted Evil


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 Exclamation


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 Laughing



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 Razz

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.

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


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.

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.


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 Very Happy

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. Idea
