only thing that may sway me from turbo is...would a turboed 2.5 beat a mostly stock 3.5?

Ummm, a good 8 psi kit would do it. You would be risking the integrity of the qr25 though. That motor isn't very strong. However, even though it won't really hang with a 3.5 safely, you will beat everyone else in your class

yeah, and it should beat the 3.5....nissan unveiled the altima R-tune 2 years ago, it never went on sale but it was very quick http://cars.ign.com/articles/713/713871p1.html the altima R-tune was nothing but altima 2.5s with aftermarket cams, Cold air intake, headers, a catback exhaust and suspension upgrades....the R-tune 2.5 altima according to nissan is much faster than a 3.5 S-tune which is nothing but a 3.5 with exhaust...so turbo'd 2.5 should murder a 3.5

Yea, not to sway from your hope here, but the 3.5 is a full 100 more hp than the 2.5. To pull 100hp from this motor, you would need a great tune as well as internal upgrades running at 8+ psi. That would be a 60% increase in power. Not saying its not possible. Just improbable for the daily driver. Hope it works out though! I'm fairly certain SFR is going to be doing a 2.5 turbo after mine

Still waiting on a supercharger for the Altima Coupe.

Better, IMO than a Turbo especially with the V6 CVT.

i think it would be better with either the v6 or 4 cyl with cvt

don't hold your breath my friend.. for ome reason, comapnies do NOT think they have a big market for a supercharger for the A/C .. And as much as Stillen has helped out our car and been the absolute forerunner regarding mods for the A/C ,even they are hesitant about pouring all that money into R&D for this project if they aren't gonna get their money back in the long run..

this has happened with nissan vehicles in the past, and that's not something they are willing to do again (understandingly so)

That.. sucks.

One of my biggest factors for getting the Altima Coupe was the possibility of a supercharger down the line.

I feel you... if I were you, and I wasn't such a modder,. i would just get the G37 like you're contemplating doing! Its a bit slower than a trubo or supercharged NIssan A/C, but for the price of an A/C plus the supercharger, its not a bad bargain!

I spent months prying Stillen and Vortech to do this. They are now in the talks of producing something jointly, but nothing solid yet.

Possibly! You have the perfect transmission to do it on

my knowledge with Turbo, and SC's is limited to nill. Though I would think a turbo would mate perfectly with the CVT due to the ability of the cvt to hold high rpms and not have to build power between shifts and build up rpms again. Correct me if I'm wrong, but isnt that the point of a SC? To not have to deal with the lag of power loss when rpms drop down again, and to keep more low end grunt?

You are right with the turbo and CVT. They will mesh together well. With the S/C and CVT, it will essentially be the same, with more low end tq. You will be lacking on the upper end power, because this isn't where s/c's do their work.

To get good power/response from a s/c, you want a larger motor, so it can push the belt and pulleys attached. S/C's typically don't do well attached to 4 cylinders. You're best bet for F/I with 4 cyl's is turbo

the issuewith the CVT is the fact of throwing 370 - 400 horses at a steel cable repeatedly! will it hold up is the $64,000 question!

Dont under estimate the QR motor guys. I know of 3 guys in my area who have boosted QR's in their Specv's and they run strong with no internal work done @ 8psi's. Their track times are low 13's as well.

so i recently read that A2G is having his turbo'd cvt dynoed soon, so knowing the issues regarding dyno's and cvts, i was wondering if he could put it in the manual mode and perform the dyno, and if this would give a more accurate result,

I believe the plan is to just put it on the dyno and see what happens, all the while keeping in mind the issues with the CVT and dyno...leaving in third won't work as the car automatically jumps to the next "simulated gear" when it approcahes redline

i really hope his turbo doesnt trash his transmission, because owning a cvt myself. i would be rather relieved to find that the cvt is stronger then what i imagine it to be

Sorry about that guys, heres the update. Turbonetics has taken FOREVER to build this turbo. They build them by hand, and made to order. Sometimes particular pieces of the turbo get backordered and they take a while to complete. This is what happened to me. The ceramic internals were on backorder until last week. With that being said, the turbo should be at SFR no later than friday. SFR cannot control how fast Turbonetics makes the turbo, that was the hold up to this point. However, once the turbo gets there, it will take 30 min to bolt on, then its off to the dyno

So, the jigs are done, (copies of the prototyped system, for production), and everything is being put back together on the car. Some of the piping is at the polishing shop being glamozired, then it will come back, and they will install that. That will be everything put back on the car, except for the turbo housing and tunning computer. The tunning computer is getting there tommorow.

and I know a half a dozen who have trashed their QR25 motors after 6-8 months of use at 7+ psi The QR doesn't come with forged anything. The internals are extremely weak. I would hang around 5 psi for longevity

Tim seems to think there is a dyno in the area that can read out the CVT, we're not sure though. There isn't a way to create a close to 1:1 gear ratio, required for a proper dyno readout because, the CVT has no gears. We are probably going to end up guesstimating based on 0-60 times and psi vs the other VQ35DE kits he has created. They just finished an 05 Maxima last week. Dynoed at 320 hp to the wheels @ 5 psi

The guys I know have been running strong for 1+ years My buddy blew his motor only becuz somehow his boost gauge was at 15psi when he ran a 350z So that was a human error but at least he won The other 2 are still going strong

Yea, I mean you can build them right. Turbonetics makes an absolutely amazing kit for the Spec V. Again, its a kit built for that car. If you wanna put something on your car, thats cool, by all means, I encourage entrepreneurship. Just be careful with it, and do it the right way the first time
