OK Guys... The Time Has Come S/C here I come!

[Tampa G35 Sedan 6MT]

I don't know what to do...

I think vortech does sell the full kit that comes with warranty....

But i think you still have to do other things to it to make it work

DJ

[Tim30250]

have you thought about other options? Stillen maybe?

I just took a quick look at that. It's a whole different type of s/c. It's a roots/twin screw type not the centrifugal type like the Vortech. That's not a big deal though, those blowers tend to make more low and midrange power than centris if that's what you're looking for. My concern was when I read this.. and I quote ..

"Fuel is supplied via a 7th injector that is mounted in the inlet tube. It is regulated via a electronic unit that is factory set for your vehicle."

That all seems a little scary to me. I don't want gas squirting in my intake tube.. again, it's not a proper fuel delivery solution, it's a patch. A proper kit needs to come with larger injectors (possible new fuel pump depending on capacity of the stock unit) and a tune, not the "electronic unit" this kit comes with.. whatever that is.

A warranty really isn't something you need to worry about too much with a supercharger, especially a Vortech. The units are virtually bulletproof by design. It's essentially just two metal gears and some bearings...not really much to go wrong there. Most of the units last 75-100K miles before needing even a minor rebuild. For most people this is long after the warranty has expired. 99.96% of the time they fail prematurely is due either to improper lubrication or people overdriving them with smaller pulleys for extended periods of time.

The larger concern is what the added boost going to do to your engine (lean it out) if not tuned properly. That damage will not be covered under any warranty since it isn't the fault of the supercharger.

I'm way to new to Infinitis to give any specific advice, but I will say keep researching and find a reputable company that has built, tuned, tested, and proven an all-in-one bolt on kit, or find an independent tuner that has LOTS OF experience with your type of car and supercharger. There is too much at risk to attempt designing a system by guestimation or trial and error.

I think with the Stillen you would need to change your hood too...

[Tampa G35 Sedan 6MT]

Yea And I don't wanna get a new hood lol...

I am still waiting on a response from the seller of the kit to see exactly what he has purchased and is included...

he has this same system on his g35 and purchased this for his wife's 350z but then they bought a C6 vette....

Ill keep you guys posted...

I'm still new to Nissan/Infiniti, but I was wondering... does someone just make a kit that comes with the fuel delivery upgrades and required software tuning?

I installed a S/C kit on my BMW about a year ago, and it came with everything I needed from larger injectors, plumbing, new spark plugs, appropriate sensor upgrades, etc. and I sent my ECU in to get flashed with a proven semi-custom tune specific for my car. BTW, I am also running a Vortech V3, it's a mild kit though ~6lb boost. Anyway, the car started right up, ran flawlessly, and has been completely reliable ever since. I've never had to touch or adjust a single thing after the install. Personally, I wouldn't try to piece a kit together. I would definitely opt for a package with a proven track record that others have installed successfully before me. That's worth the extra money for me to save time, frustration, and possible disaster if something isn't calibrated correctly. IMO, my Bimmer is way to nice of a car to take chances with, and so is your Infiniti. Save up a few extra bucks and do it right...the first time.

Couple pics after the install...

Yes, there are companies that specialize in boosted Nissans that can supply everything you need. As of this writing, a supercharger for the v36 does not exist yet. You are also in a different situation because you have an HR/VHR motor with dual intakes and MAFs. Unlike the OP, It makes more sense to go with twin turbos on a v36. A complete turn key set up would be around $15K, more or less depending on whether or not corners are cut. Your advice to save up and do it right the first time is right on the money.

I'm sure you'll agree that reliability largely depends on how one drives the car. I have about 17K boosted miles on my daily driver with no issues either.

[Tampa G35 Sedan 6MT]

Im still waiting to hear back from the Seller to see what is exactly included... He seems to say that all that is needed is a tune.... The Guy at ZFever says that He will re-flash the G's ECU and that is better than purchasing a new ECU... He said that they fail alot... and that the Stock ECU's are bullet proof!

And I would be alright with 4200 bux.... out the door for everything...

DJ, you're wanting this thing to magically come true so badly, you're getting yourself all spooled up.

Dude - There's NOTHING ELSE with the kit. It's exactly what was shown.

You STILL need all the stuff I listed. Why are you asking the seller what you need?

If he's telling you "all that's needed is a tune", then he's a moron. Ask him where the extra fuel comes from. Ask him what's gonna tell the injectors to fire differently. Ask him what's going to modulate fuel pressure.

And I don't give a rip what some guy said, you're not "re-flashing" the G ECU for 8 psi of boost without some sort of add-on / piggyback. He may be using something like UpRev, but that's not getting done for cheap.

"He said that they fail alot... " What fails a lot? Which ECU? Where are the details?

I think you're getting snowed.

[Tampa G35 Sedan 6MT]

I Know More is needed but I am really wondering what the hell this guy was smoking when he told me about the ECU... I think he said the UTEC's are the one that fails... but i could be wrong... IDK lol....

And once again Thanks for your help and I will keep you posted on what happens... maybe i will spend the money.... it keeps me from buying a new car lol... and after all the G is paid for

DJ

[AZhitman]

I'd recommend a call to Tony (or Jeremy) at UMS Tuning here in AZ.

He's working on my G right now, and knows the Vortech system inside and out, as well as your options for tuning.

[Tampa G35 Sedan 6MT]

Do you mind sending me the number?

Thanks

personally I am not a fan of those "all in one" kits, they are made for people who want to pay a bunch of money for something they can put on their car with no knowledge of whats happening...

KNOWLEDGE IS POWER!

You can go back and read previous posts and see what people have done and what has worked/failed..

I think for major projects like that, if you have an idea in mind of what you want to spend, then DOUBLE it, you'll be much closer to where you'll end up.. At the end of the day, its the small stuff that adds up real fast, not the expensive stuff... I think Greg would attest to that!

[RED_DET]

The bottom line here for boosting any N/A car is the following:

1) High compression is a b*tch and it will bite you in the a$$ every time, so remember that because you will be stuck with minimal amount of boost on that engine (7-8psi). I say this now because after time you will getting addicted to that boost and then it will get old and you will want more. You say no that won't happen, but I'm telling you it will, I own a boosted car.

2)You need larger injectors, larger fuel pump, piggy back engine management, intercooler/piping & tune just to get this off the ground.

3) You need to monitor vital statistics of that motor, so you will need a wide band gauge, oil pressure gauge & boost/vacuum gauge at the least.

4) You might as well plan on getting another clutch, because that stock one isn't going to last long.

5) At some point in time, you will need to upgrade that single path 2.5" exhaust.

6) Problems always arise with boosted cars, I'm not saying they can't be reliable, but it will take some work.

AZ & I are not trying to deter you from doing this, but at least have an understanding of what you are getting yourself into. Not to sound harsh, but to me it doesn't seem that way. But that is ok, we all were noobs to F.I. at some point in time.

I am a HUGE fan of the "all in one" kits for several reasons...

1) I installed one on my BMW and it works flawlessly and without any guesswork.

2) I didn't have to pay a "bunch of money" as my kit cost less than $5K.

3) I did not have to double my budget estimate since everything I needed came in the kit and there was no need for me to purchase or fabricate anything additional.

4) I didn't have to research what worked or failed for others because the kit itself had professional R&D (and tune) behind it and had already proven its success and reliability on countless cars before mine.

5) I have a very good understanding of how the kit works since I installed the whole thing myself using the detailed instructions that many others before me also used successfully. I know exactly how everything functions except for the ECU programming. Of course, I didn't know how the OEM program worked either. Turns out, both work perfectly, so I guess that's something I can leave to the experts. If it ain't broke...

6) A supercharger install does not have to be a "major project." With my kit, it was all bolt on. The install procedure was well-documented and easy to follow; and since nothing was modified, fabricated, or butchered, the whole thing can be easily reversed and replaced with stock components if I need to sell the car.

7) After my install, I stepped on the clutch, turned the key, and it started right up and idled perfectly. The car also runs and drives just like when it was stock until I press down on the go pedal to call up the boost. There were never any issues that I had to figure out with tuning or otherwise. It never stalled, misfired, ran rich or lean, threw a code, required any troubleshooting, or gave any indication that the s/c didn't come on the car from the factory. My car is completely reliable, and I will never have to perform any additional maintenance beyond changing the supercharger fluid every 7500 miles.

So why exactly should I (or anyone) have gone with a piece-it-together-then-tune-it-yourself-and-cross-your-fingers kit?

[BrandAidDesignG35]

I know how you feel, when I ventured into installing nitrous in my G, I was cautioned quickly by several great members on this site... which without their knowledge, I could have made some very poor decisions.

I think it would be sweet to have FI, but don't rush anything, and don't look at it like $4,200 is your MAX!!!

You need to figure out pricing on everything you need first, order the parts as time / money permits, and have it installed professionally when every las part has arrived.

Good luck, man, you will have to post up some vids/ pics of the process...

DOOOO EEEETTT!!!!

[joe603]

Great info here! The bottom line is that installing FI on a car will not be cheap. I've looking into doing the Vortech with my G, and concluded that 6k is too much $$ for the HP gains and problems that might crop up. I have other reasons for scrapping my plans, and she's worth it!

The good thing about SC systems is that their easier to install vs. a turbo. That's where you can save some $$.

[elwesso]

The question here is does such a kit exist for a G35, which you asked earlier... From the sounds of it it does not exist.. For the BMW, sounds like it worked out great for you and thats fantastic... and for 5 grand, thats a hell of a deal, and you probably added 100 HP.. From the sounds of it, the BMW lends itself to boost better than the G35 does.

[Tim30250]

I am actually surprised that there are not more companies designing FI systems for these cars. The BMW also had its share of obstacles (10.5:1 compression being one of them) but systems were coming out 2-3 years after my generation first went on sale and they all proved reliable although some were better performers than others. The G35 has been out for many years now and I haven't been able to find many bolt-on FI kits out there. The demand seems to be there, so I'm left to wonder what the factor is that's preventing development. Is it a tuning issue? Is it capital investment for R&D? Not sure, but if someone would step up and design a good system, they'd make a mint.

Until such a time comes, if we are doing these kits piece by piece it's super important to find someone that REALLY knows what they're doing when it comes to the tune. Even then I'd be apprehensive if they hadn't personally seen all of the kit's components working successfully in concert with their tune.

[elwesso]

Well on that note, the upside to this method is you can kind of mix and match your stuff, and as long as you get an EMS that your tuner (which could be yourself) is familiar with, it allows you the freedom to do kind of do what you want instead of buying a "all inclusive kit"...

Ive been involved with nissan/infiniti and BMW, and it seems like the BMW guys are more content with the "buy it bolt it on" kits, and it tends to be what they want... nissan guys like to buy their parts and assemble it all together, sometimes it works great, other times it doesnt...

Bottom line is, if your doing it you need to do adequate research and really know what you're getting into before you jump on the bandwagon, and I dont think anyone will disagree with me. You dont need to know everything, just enough to be dangerous!!

[Tampa G35 Sedan 6MT]

Im still considering the kit and going and spending the money to get what I want.... I will keep you guys posted and thanks for all your help!

Good luck, bro!

[Sentientbydesign]

Greg,

Why won't the UpRev option work? I can understand why your G wouldn't work since you have the older ECU, but the newer ones are tuneable via Osiris.

Are the lookup tables not large enough?

[gwoods]

"Fuel is supplied via a 7th injector that is mounted in the inlet tube. It is regulated via a electronic unit that is factory set for your vehicle."

That all seems a little scary to me. I don't want gas squirting in my intake tube.. again, it's not a proper fuel delivery solution, it's a patch. A proper kit needs to come with larger injectors (possible new fuel pump depending on capacity of the stock unit) and a tune, not the "electronic unit" this kit comes with.. whatever that is.

You don't want the intake manifold backfire???

The intake manifold on most cars is a "dry" manifold meaning it is designed to handle air not fuel. On the hemi rams I saw a few wet nitrous trucks that had a intake backfire and it was not pretty!

Heres a link to a Mustang that tried to run fuel in a air intake manifold

[gwoods]

why not do a single turbo?

The supercharger uses horsepower to make horsepower, the turbo uses wasted exhaust gas.

[Tampa G35 Sedan 6MT]

OK I made up my mind...

Not gonna do it....

I was driving the G Yesterday and im like.... What the hell am i gonna do with more power....?

Then bad things came to my mind....

Im like.... well Could spend the money on other things.... and I am Just gonna save the money so that When I am done with My MBA I can buy something really worth it...

I really want a AMG Benz... A SL65 or CL 65.... I want a v12 with twin turbos...I can pick up a 2006 S65 for about 50-55 K Price range....

Then I started looking at the ONE and ONlY GTR.... and they are like 65k

and Im sure in another Year they will be like 50-55k and that is when I will be looking to purchase one....

That really isn't bad when you think the new loaded G's are in the 40k range...

Thanks for everyones help! I really appreciate it!

[Tim30250]

why not do a single turbo?

The supercharger uses horsepower to make horsepower, the turbo uses wasted exhaust gas.

OK, that is waaaaay to elementary of a perspective to make a proper decision. If the turbo's higher efficiency was the only factor to consider, nobody would run superchargers. I know there really aren't many all-in-one kits for the Infinitis yet, but there are for my BMW, both s/c and t/c. I choose the s/c for the following reasons.

1) The supercharger kit cost less than $5000, turbocharger kits START at $7500.

2) The supercharger was a much more simplistic install, I was able to do it completely by myself and in about half the time (or less) it would take to install a turbo. The turbo involves changing exhaust manifolds (a total nightmare on my car) and other modifications to the exhaust like relocating O2 sensors.

3) To plumb the turbo system is another nightmare, you often have to remove and reinstall chassis components to make way for the discharge tubing.

4) The turbo unit itself runs crazy hot since it is fed by 1000 degree exhaust. It requires tapping into the car's cooling system to run additional lines to keep the monster running at safe temperatures. A larger radiator may also be required because of this.

5) Speaking of tapping in... you also have to tap into the car's own lubrication system to run oil through the turbo, and tap (literally run a tap) into your oil pan for a return line. Also, since the turbo is now feeding piping hot oil back into your engine, a supplemental oil cooler (separate of the intercooler) needs to be installed to keep from basting the engine in 300+ degree oil.

6) A single turbocharger is much larger than a supercharger and needs to be mounted on the side of the engine. Not much room there on any modern car last time I looked. It's a crazy hard install (or an expensive one if you pay someone else.)

7) My supercharger is completely self-contained. It requires no additional cooling and doesn't recirculate any of it's oil back through my engine. Yes, it has to be changed independently of the car's oil changes, but only every 7500 miles, and it takes all of about 10 minutes.

8) The entire supercharger install was done from the top or front of the car and there was enough room to work on each facet of the install fairly comfortably.

9) The turbo install overall is fairly major surgery, the supercharger install is more like an outpatient procedure. When it comes time to sell the car the s/c kit, it is more easily reversed and replaced with the stock parts that were previously removed. Since the turbo required more butchering of the car to put on, it will naturally demand more work (and probable repurchase of OEM parts) to remove.

10) The turbo (for my car) would require a different front bumper cover to make room for the massive intercooler. That's another $500-$1000 for the part and the paint labor.

So yes, the turbo is more efficient, but I had to ask myself this... Is the turbo and its ~25 extra HP worth 20 hours of additional labor and an extra $3,000? For me, the answer was no, but for the more adventurous types it may be yes. That's why both options exist... different strokes, different folks.
