A company called Speed Force Racing made a turbo for the Altima. Sounds like they'll adapt it to other VQ35DE vehicles too. I know I don't have $4500 laying around to do it though. The question is if the CVT and other components can handle it...

Your quest for speed through aftermarket mods is amusing.
I'd only buy/lease a turbo or supercharged ride from the factory.
If I wanted a superfast ride the size of the MO, I wouldn't buy/lease a MO. |

Not really a quest. I have a 2004 Maxima which is my project car. So I'm usually reading about Maxima enhancements and post the good ones here that might apply... |

Can the CVT handle the extra power from a turbocharged VQ? My guess is that it can, but at a price. That price being reliability and longevity.
It would be interesting to see how well the CVT stands up to 300 or 350 horsepower. I am sure someone will one day buy a 5 year old MO and strap on a turbo or supercharger. I just hope they join this forum so we can read about it.

The other issue most Nissan cars have are the engine compartments are so cramped. If you notice in the above link, they actually relocated the battery into the trunk. |

H-
Nice video. At first I thought the "SHOT2X" license plate had something to do with the mods on the car. Then I realized he is a Purple Heart recipient and was shot two times. Duh.

| I highly doubt the CVT's gonna handle it, that's why I've contacted an importer/exporter about the 4 speed from south africa :) I want FI so badlyyyyy but yeah he'll get back to me Monday he said |

Please let us know. This maybe a less expensive fix for all those with CVT issues as well. |

That's what I was thinking as well, and I want to add power that the CVT won't handle |

Well, good luck.
I can't see a 4 speed auto, brand new, from a dealer, being any cheaper than a CVT.
Then there is shipping and install..........

Your quest is really getting ridiculous!. Change the transmission so you can turbocharge! Come on....
I believe though that MO in Central America has a conventional automatic. I don't think you have to go to South Africa. |
|
|
| njjoe |
If you are considering installing a conventional auto tranny, you might as well do the performance mods beforehand, run the CVT until (if?) it fails, then install the auto tranny.

I'd rather do it right the first time, all I want to do is get the 4 speed and do some FI and we'll see where that goes
and I've already went through a CVT so I'm weary about them :) |

| That dude never got back to me, but anyways I think I'm gonna go ahead and start ordering stuff for the turbo, I think the battery location MUST BE MOVED to even make room for it like that altima I think they did it on there. So yeahh woo |

Hmmm... Let me get this straight. You intend to install a turbocharger in your MO? Is that correct? If so, please post a running diary so we can see how it goes. I am sure there are quite a few members like myself who will be interested in this project.
Good luck.

Just out of curiousity, would the transmission from an FX35 (or 45) fit?
Or do they use a longitudinal engine layout/ entirely different drivetrain that precludes its use?
Not that I'm planning on turbo (or supercharger). |
|
|
| Hilbe |
| FX35/45 are RWD. Totally different than the Murano... |
|

| I believe that there is a kit to beef up the CVT if a supercharger is put in the vehicle. What do the Z's have in them from ProCharger? Are they strictly stick or also CVT? |

Nuf.Evah-
Where are you getting your info from? You are definitely misinformed. Nissan dealers don't even repair damaged CVTs, let alone beef them up. No one, and I mean NO ONE, is marketing a consumer kit to strengthen the MO's CVT.
Z's come with either a 6-speed manual tranny or a 5-speed auto. The JATCO CVT is never even mentioned when discussing the Z.
You may want to reconsider putting a supercharger on the MO. It may look good on paper, but the longevity of the CVT will be seriously compromised by the additional torque.

I was told by a speed shop that ProCharger makes sorry blowers for the Z and some Infinities and they come with a kit to beef up the CVT. Is the CVTs in those cars different than in the MO? I wrote ProCharger and the man that owns a couple speed shops here twice talked to them at Vegas shows to try to tell them that they were missing the boat by not making one for the MO instead of the Infinity. There are many more MOs on the road than Infinity's! I do not know what the limitations of the CVTs are. I am new to tis site and have never had a problem with mine in 60,000 miles. I would think that if they wanted to do it they would come up with the answers and the product to do the job. Maybe this is why they aren't interested but when I talked to them directly they told me that they were disappointed in sales for Zs and Infinitys and made blowers mainly for Mustangs!
I wish I could get a bit more pep out on mine, there isn't too much made to help these cars go at all faster. I pray for mine every night but when I look under the hood in the a.m. nothing has changed...? I have owned some pretty slick cars over the years and I can't say that I am the least dissatisfied as I knew what I was buying. It has all the creature comforts and does handle well after a few bucks spent. I will end up with another hand built car to my specs and 3 sec 0-60mph to drive ocaisionally. |

| Nuf.Evah |
| OK you are saying that the zs don't have a CVT but a regular automatic tranny. That is probably why ProCharger doesn't want to make the unit then! They do have a tranny kit for the Z and Infinitys. Oh well... that's one dream that ain't going to happen! I guess I can always change the gears in the rear and crank up the rpms LOL!!! Had a set of 488s in my '68 camaro ions ago, an 11 sec car. |

| Nice if someone can answer your question Kris!!! I'm going to hang around until someone answers that! |

Nuf.Evah-
I'd love to see someone put a blower in the MO, and I am sure someone will one day. It will be interesting to see how well the CVT handles the additional torque. Maybe it is strong enough to handle a blower. If not, then the exercise will cost 6 or 7 grand for a new CVT.
Although automotive CVTs have been around for decades, they were limited to low power, small displacement applications. JATCO, the company that makes the MO's CVT, markets five different push-belt CVTs. The strongest one, which is used on the MO, is designed for engines up to 3.5 liters.
As of this date, no one other than JATCO even repairs the CVTs. If your CVT fails, the guys at Nissan simply swap it out with a new or rebuilt unit. Troubleshooting is limited to a "go, no go" philosophy. If it is a "no go" then swap it out. No tear-down is involved.
If you do decide to add a blower, please post the project here so we can see how it goes.

I do not have any questions on trannies...I know all I need....;)
Seriously, Infinitis and Z's are using Nissan excellent 5-speed outo-tranny. Murano, and now Altima and Maxima are equiped with CVT's.
As per Joe's post - it would appear that nobody but Nissan dealers can deal with CVT's. And they do not repair them. They swap them for new or reconditioned units. For $5k - $7k a piece! Good money maker for Nissan...:(
CVT is the only reason I am getting rid of the Murano once warranty expires... |
|
|
| Nuf.Evah |
Now things haven't been made in years to repair, LOL ( !!! ) only to replace! I had a Moshe Bentz and I had a/c coming out one side and heat out the other at the same time! They unsnapped a black module and took it out and replaced it with another module and $400.00. Two weeks later the fan motor just happened to go out! Gee another replacement! It does not surprise me that the CVT will not be worked on at the dealer, are you kidding that would be like service and require an educated mechanic on CVTs. I never gave much thought to getting rid of the car once warranty runs out at 100,000 miles buy I will now. Now I think I would feel like I was sitting on a time bomb waiting to go off and cost $6-7K to replace after warranty! I have an '03 and isn't warranty for 5 years? Believe me that I got my moneys worth out of my extended warranty with a headlight problem that cost the new module $400 and then water got into the headlight casing $400 and the transfer case I believe had to be replaced as the AWD lock switches used to not reset when you turned the car off and it burned out the transfer case that was I think $1800. I don't know if that is the right terminology but I think that was what that was. I always wondered if there was a recall to replace the switch as they did on mine. I read here somewhere that there is a recall on alternators??? And one for a gas tank shield. What's up with those? Engineering mustn't be what it used to be!!!
I guess I'll just wait and see how the CVT holds out and sit around eating flies til then! |

I'd like to see how long the bottom end of a 10.3 to 1 compression engine would last if turbo'd..... not very long.
Blowers are very different.
Even on top fuel dragsters the pressure at the manifold is zero at speed.
Whipple screw drives get to 7 psi, but roots types just get rid of the vacuum. |
|
|
| Nuf.Evah |
| Well, they have to be made for what the engine will take. I'm not in the least interested in just slapping one on, it has to be tested for the motor and the amount of boost it can handle or caboom! |
|
|
| Nuf.Evah |
| I'm not that knowledgeable about these, more like standing alone in the field waiting for the trolley to go by! What are these? |
|

From what I understand, even the forced induction Murano GT-C prototype in UK is electronically torque limited to 265 lb/ft to protect the CVT, although that torque holds constant to a higher redline to achieve the 300hp rating. Even with the factory modified Bilstein suspension, it was not as fast or as sporty as a sports car.
I think the money spent modding a Murano is better spent on a genuine sports car if you want to go fast around corners. But to each their own, and if you do mod, post a log of your activities for us to read here, as many would be very interested in following along. |

A Whipple SC uses two interlaced screws.
A roots type uses straight lobed rotors.
Either way, even with a turbo putting out a small amount of boost, you would have to run racing gas to hold down detonation.
If you are looking to do BRIEF periods of power beyond stock, use NOS. Be prepaired to yank it off when the CVT goes south or the valves or pistons melt before taking it in for warranty repair.
NOS likes to find a way between your ring lands and melt a hole through the skirt of the pistons. You'll know when that happens when a huge plume of smoke erupts from your exhaust.
Then you'll say HOLEY SHEET BATMAN!

Thank you for the info but I don't know if that is exactly the type of blower to put on these cars. Have you seen the ones ProCharger makes? I think they probably don't for the Murano due to the CVT. This looks more like something to put on a dragster!!! Well, now I know!!! LOL!!! NOS doesn't interest me in the least as yes I've heard about that plume of smoke!!! I think that I have to change my expectations and wait until I get a play car next summer! Check out www.super7cars.com gallery, video!
Thanks! |

| The quest for speed or the cost of it! You guys want more than what your money can buy! You are going to get way over your heads faster than your cars are going to go down the road leaving parts scattered all over the highways! The MO was not meant for Speed Racer! You are pushing am envelope that I seriously doubt that you can lick.... |

Sorry, but your information is incorrect.
A Roots style supercharcher can have straight or curved rotors. The Roots and the Whipple are the same type of supercharger, which are rotor superchargers. A Whipple just has more twist to the rotor than a GM X-71 style super charger
From http://64.78.42.182/sweethaven/Mech...sNum=7&modNum=1
SUPERCHARGERS
A supercharger is an air pump that increases engine power by pushing a denser air charge into the combustion chamber. With more air and fuel, combustion produces more heat energy and pressure to push the piston down in the cylinder. There are three basic types of superchargers:
Centrifugal supercharger
The centrifugal supercharger has an impeller equipped with curved vanes. As the engine drives the impeller, it draws air into its center and throws it off at its rim. The air then is pushed along the inside of the circular housing. The diameter of the housing gradually increases to the outlet where the air is pushed out.
Rotor (Rootes) supercharger
The Rootes supercharger is of the positive displacement type and consists of two rotors inside a housing. As the engine drives the rotors, air is trapped between them and the housing. Air is then carried to the outlet where it is discharged. The rotors and the housing in this type of supercharger must maintain tight clearances and therefore are sensitive to dirt.
Vane-type supercharger
The vane-type supercharger has an integral steel rotor and shaft, one end supported in the pump flange and the other end in the cover, and revolves in the body, the bore of which is eccentric to the rotor. Two sliding vanes are placed 180 degrees apart in slots in the rotor and are pressed against the body bore by springs in the slots. When the shaft rotates, the vanes pick up a charge of air at the inlet port, and it is carried around the body to the outlet where the air is discharged. Pressure is produced by the wedging action of the air, as it is forced toward the outlet port by the vane.
Also, NOS does not "find a way between your ring lands and melt a hole through the skirt of the pistons"as you stated. If you're melting holes in pistons using NOS then you're running too lean. |

| Now to add to the family there is a 2004 Nissan Maxima with this kit in it. There is a lot of extra fabrication that had to take place to adapt it from its original Altima setup... |
