still no turbo, eh?

[sentrastace]

So no turbo was ever developed for the CVT sentras 07 and up, right?

god dammit.

I just tryed Google.com and found some Info. and it only took me 12mins to find:http://hubpages.com/hub/Nissan...ieces

zerothread/307224

I just thought I would try to help.

[unmei]

no. there is a build on cardomain.com, but the cvt was taken out and replaced with a manual transmission. also, one of the the moderators for the altima section of this site had a 3.5 se cvt turboed, but supposedly it had issues. supercharger would probably be better :/

[wanner85]

I think a turbo would actually be very good with a cvt. A super charger would have a lot of low end power off the start which could be more prone to cause damage. A turbo would match the cvt perfect. The compressor would stay spooled up the entire time as the throttle plate would remain open, and the cvt would keep the motor just before redline. Even a 5-6psi non-intercooled kit would be pretty sweet.

[Showcase]

yea but theres no way that the cvt will hold up for any lenght of time with all that extra torque. Its meant for fuel economy not racing.

[wanner85]

Yeah. What was I thinking?

[nametakennow]

Depends on the type of supercharger.

Nissan's V6 CVT has been tested internally and can't take much more than 300ft/lbs IIRC. I'd imagine the 4cyl version is even weaker. Remember that would be a crankshaft figure too, so there's not much room for adding power at all.

[djtorello]

If you have a 2.0L, you can get OEM turbo parts, off the Sentra's Sister car, The Renault Megane III. Same platform, Same engine except has a turbocharged option for our shared 2.0L.

but what about the fact that mine is CVT?

[nametakennow]

The Megane also comes with a CVT, so if it can handle a turbo, so can yours.

[wanner85]

I wouldnt worry about the power handling capabilities too much. There seems to be a lot of negativity about the CVT. But like I said earlier, a 5-6psi turbo would probably be just fine. My reasoning behind that is the fact that the SER comes with a CVT and it is rated at 177 hp. Also, the SER has the whole flappy padel thing going on. So the CVT in the SER can handle 177hp and the abuse of people holding it "in gear" and bashing it around like a wore out hammer. The only thing Im not sure on is if the SER CVT and the 2.0 CVT are the same. I would bet the CVT in our Sentra's could withstand an additional 40 to 45 hp via a turbo. Also, Nissan must be pretty confident in the technology because I just recieved a letter in the mail stating that the warranty for the CVT is now extended to 10 year - 120,000 miles. The life of the CVT may decrease slighty, but with proper maintenance and possibly an external fluid cooler I think it would be fine. Now, I'm not saying that a turbo producing 8psi or higher wont damage the transmission. So, a person like myself could waste $3,000 plus, trying to setup a 5psi turbo setup to add only 40hp or could just call it a day. It would all come down to how much money you want to lay down for a minimal amount of horsepower, and how reliable you want your car.

[sentrastace]

ARGH i wish someone who knew what they were doing would do this so I would know if it was ok to to do it to mine. im soo scared to take the risk because if i damage this car, thats it, no more money for a car lol.

[wanner85]

Dont be scared. And, kinda off subject, I'm new to Nico, but I thought you're selling your Sentra, nice pics by the way.

I wouldnt expect anyone to persue a putting a turbo on the 2.0 CVT. Someone will just have to try it.

yeah i decided not sell the sentra, I love it too much lol. and yeah, i doubt anyone would want to turbo a 2.0. not that many SE-Rs are turboed either, ugh. call me crazy

[djtorello]

the SE-R's already have an external transmission cooler. Not sure on the 2.0's, never really looked.

The Renaults turbo 2.0L is rated at 250hp and the crank, so im assuming the CVT can handle it.

[ABNRML4U]

I found some Info. On a turbo B-16 Just thought I would help. http://www.cardomain.com/ride/2965367

[mmm240]

and yeah, i doubt anyone would want to turbo a 2.0. not that many SE-Rs are turboed either, ugh. call me crazy

Mine's turbo. Ohhh, you meant a B16, lol.

I say you should boost it and find out. Take it easy at first at the stated above 5-6lbs and see if you are happy with that. I'm only at the stock 7 and it's damn fun!

[djtorello]

that was the person i warned you about in the last thread his cardomain was posted. He blew it up. You cant just slap on a turbo, and have no working gauges. no oil pressure = turbo go boom.

[mmm240]

You cant just slap on a turbo, and have no fuel and ecu upgrades

FTFY

There's really no reason a stock engine can't handle a few lbs of boost.

[mattse-r]

Eh, I agree with you also but the only question i have for that guy is the boost pressure. For all you know he was puting like 40psi and hoping the engine will stay together lol. I doubt you would have to much trouble if it had 5 or 6 psi. Still smart to have working gauges though, no matter how much boost

[terrycs]

I'd be cautious ... it may not break down right away, but anytime a NA motor is boosted, the life of the motor / transmission is reduced.

[Spoolin4days]

Just to make it clear, the CVT in Altima's isn't super reliable, it seems Nissan extended the warranty because they know it. I know the CVT in Versas and 2.0 Sentras is a weaker version of the Altima unit, so you do the math. Not to down your ambitions but it isn't advisable to boost on it. Plus you'd void the warranty anyway.

[b13boy!]

my bro has a honda thtat he was running 5 psi of boost on all stock internals and it lasted about 6 months before he threw a rod but if you take care of it it should lasta little while but dontplan on it lasting for life cause it wont just make sure you have all working gauges and everything is in check

[djtorello]

The MR20 is a dumbed down version of the Renualts. The stock internals are good to about 10psi. The CVT seems iffy for some, I for one havent had a problem being boosted or not.

[djtorello]

BTW, those with the SE-R and SpecV, there are a few Turbo kits found on Ebay. What most people dont understand, is that the B15 sentra turbo kits will work just fine, with little modification to piping.

To make it even more clear. Does it really seem logical for a company such as Nissan to extend the warranty AND reimburse anyone who has previously paid for repairs, so you do the math. Also, from the way I understand the Magnuson-Moss Warranty Act of 1975, my warranty would remain, (unless the turbo could be proven to cause the failure).

[djtorello]

There is someone who turbo'd a sentra 2.0. Though changed over to manual for the only reason, everyone is afriad of the CVT.

I have a CVT and Supercharged. 400hp doesnt seem to be a problem, maybe im lucky, who knows.

Here's a pic of that 2.0L MR20 turbocharged:

[dgreen29]

that guy replaced a good bit of the engine internals also though, that isnt stock internals. i believe he put new pistons/rods and a bunch of other stuff.

I've replaced more CVTs then you might think, I've done the math. Adding power to the drivetrain increases load on the CVT 'belt', among other internal parts and can cause the TCM to malfunction (like when trying to select the optimum ratio for conditions it can't "compute"). I can show anyone proof of it with the Consult III. I didn't say it WILL fail, but I wouldn't trust them for boost, the ones in US Sentras are not designed to deal with it. If you could alter the TCM parameters it will hold up better, but Nissan sets them up for fuel economy and smoothness, not abrupt acceleration. The CVT being installed when a customer blows their original is likely a unit that's is ugraded to reduce chance of failure, Nissan knows it's best (ie most profitable) to extend the warranty than make a recall out of it. Check on the Warranty Act again, you may not understand that altering the HP will void your warranty on the CVT. Make a new thread if you want to learn more, the OP didn't ask for this and you sound like you want to argue...

[wingedmark]

djtorello what supercharger did you use on your car and was it hard to install?
