Altima Coupe 2.5 CVT Turbo

[white1]

Some pictures of my ride while it was doing turbo...

[b88dragon]

looks good man. i wanna turbo mines as well but have no clue on how to start it up. so what kind of set up do u have? mine listing the parts and what not if u dont mine and is that a y pipe u got underneath the car?

cant wait to see the finish product. good luck

[chiapetchua01]

dude he already turboed it but from what i understand his cvt blewso he's back 2 normal right now

[coderedk]

To white1, so from having turbo your cvt engine and blowing it, do you think it's possible to safely run another turbo with different modifications on the 2.5 cvt? And also, while ur turbo worked, did you really feel a great difference in power how was the engine reacting and sounding when it did run?

[PHENOMenalVinyl]

i love how u finally post pictures of ur turbo even though it blew ur cvt soooooooo now ur trying to sell it before you tell us this...........well we already know u blew it soooooo

unless im wrong in that case sorry for being a d!ck but if u never come by to tell us about it then come and say TURBO for sale......i mean come on ur coming off in the wrong way bc now ur just sounding like ur gonna scam someone knowing that there transmission will blow

[white1]

If I wanted to scam someone first of all i wouldnt have said that it broke down on my cvt ok...... second ifi woud have known the results i wouldnt have do it. i am selling it bcuz for a manual trans. works.

He knew it wasn't worth it on the CVT but he did it anyways to see how it would hold up. Obviously not well (which we all know anyways). It will be fine on the 6 speed manual. The trans are the same between the V6 and the 4cyl. It can handle the power. If you're going to go above 300HP you probably want to get into a new clutch and better pistons, etc.

The motor can handle on it's own up to around 300HP, the CVT can not. It's a POS really. Turbo + Auto = Fail.

White: I want your down pipe k thx Get back to me.

yooo mad props to white1 for turboing his qr25.the set up looks pretty crazy but its too bad it didnt work out...btw thanks for joining NICO

[el_blacky06]

white1 im interested in buying the apexi computer. how much do u want for it?

Bump for more info

I have a 2.5S A/C 6-Speed and would DEFINITELY like to boost it. I don't want to run more then 5psi boost. Did you build the kit completely custom or order a kit? If you ordered a kit where did you order it and how much did it cost?

Thanks

It's custom, there are no kits for the 2.5L.

[cheezball1257]

I halfway beg to differ but haven't heard any reports on it.

It says it will fit 2002+ Altima's but i heard that the intercooler piping would have to be custom otherwise its good to go.

That's all nice, but half of it will not be used. Sure the motors are the same but none of the piping will fit. Things are arranged different in the engine bay. I had already looked at this option and decided to pass and do my own setup.

The SAFC hookup is no where close. The cars use completely different ECUs through a system BUS. Some wires to can hook to the ECU harness, others you have to wire in resistors and tab directory into the sensors.

The Down-Pipe will not fit.

The exhaust will not fit.

The injectors may or may not fit assuming they are the same clips as the newer motor revisions.

The fuel pump may or may not fit.

This is what I did not want to chance. Buying a full kit and having to sell or forget half the stuff in the kit. It was more cost effective to buy what I needed as it went along, then possibly upgrade later if I wanted.

If you want to check my progress take a look here: http://forums.altimas.org/zero...build

Lots of good info on what I purchased so you do not make the same mistakes. (IE: AEM FIC, FAIL) lol.

From your mods, obviously you know what you are doing if you are doing everything yourself, unless you just took it to a shop and threw money at it. If you hooked up what you have always (such as installing cams, SAFC etc) then you should be fine making your own kit or modifying a kit to work for sure.

[cheezball1257]

It certainly wasn't easy doing the stroke kit (not designed for the A/C but designed for the engine) most people don't think to look up parts for the A/C using the engine as the title instead they use the car. The SE-R Sentra's have the same engine as we do with the slightest modification so when you get something for that it more then often works (don't take my word for that incase something doesn't fit) I have JWT Cams and they give the car a nice idle and alot more evenly spread power. Turbo'ing my car is the next big project aside from dropping in a different engine and working from there but that usually makes things kinda worse since you will have a different engine (which may be able to handle turbo) you still have to build the turbo and IC mostly in part to the car. An RB26DETT runs turbo of course but setting up IC pipping and figuring placement for turbo and engine inside the engine bay on an A/C is a BIG challenge. Any help with the whole turbo situation is greatly appreciated.

BTW- Any guys from MD want to meet up sometime soon in Columbia or something? VA guys wanna meet up in hampton or VA Beach sometime soon?

Thanks all for any input

I hate seeing statements like this because now someone's going to run with it and spread misinformation around the forums. Can you provide more details on what parts you've interchanged? Were they a direct install or did you have to tailor the parts to fit? Do you have dyno proof of an improvement? Are you butt dyno'ing or just saying there's more power because of what you hear?? The devil's in the details and you certainly aren't providing very many.

[el_blacky06]

could u show some more information on how you put on cams for your car. any custom work or waz it all a fit right from the beginning? any improvement?

The RB26DETT huh? The Skyline motor? Explain to me how your going to put a Longitudinal Twin Turbo 2.6L Inline 6 cylinder engine designed for an AWD, into an engine compartment designed for a horizontal inline 4 cylinder/ V6 FWD?

Stoker Kit included:

-K1/ Carrillo Billet 4340 Crank-Eagle H Beam Connecting Rods w/ ARP 200 Upgrade bolts-JE Forged Pistons-JE Plasma Moly Ductile Iron Rings-Upgraded Performance Wrist Pins

Everything came fully balanced and designed for the QR25DE. Stock bore and stroke is 89mm and 100mm now i have a 90mm bore and 102mm stroke, i know that isn't much but i have noticed power gains but would more then likely have to sleeve the engine to run any boost.

The cams are BC Cam:QR25DE 272/264 (10.92mm) which weren't hard to install and i haven't noticed much at all as far as any power gains really, the company said 6-8 horsepower which isn't alot but i do have a better over-all power spread.

I am taking it to AllAspects in Chesapeake for a full on tuning dyno run.

White: I want your down pipe k thx Get back to me.

Hey guys im new here so please forgive my questions and thread jacking.....I have researched for days and found no tangable answer. What is a "safe" maximum hp for my 2.5 before the cvt starts slipping? I am planning to get the bd gt tuner, and a tanabe catback, and stillen headers. I have the k&n typhoon installed already. Will these mods potentially damage my transmission? Also It has <5k on it and dont want to throw away my warranty yet. thanks for the help guys..!!

[dldjros69]

Those mods will not hurt your cvt. Mod on!!!

[DReed86]

+1 you wont hut your engine with that its only when you get into the turbo area that you have to start worrying....

that being said we did have 2.5 blow a few months back and he didnt have much mods... so I would keep all of your stock modds and or clear te new mods with your dealership for warrentie purposes. Some dealers can be &itches about that stuff.

[biggie3339]

So your saying putting a turbo kit on a 2.5 cvt is a bad idea?

[wade001]

It looks like that if you want your car/transmission to last long, CVT's are pretty weak

[RicerX]

So your saying putting a turbo kit on a 2.5 cvt is a bad idea?

Search around the forum - you'll find the only guys successful with boosting on a long term basis are guys with manual transmissions. It's really a gamble on how long a CVT will hold up to extra power of that magnitude before it melts. Adidas2Go is (pretty sure the first) one that has turboed a CVT driven Altima here on the forums, and he went through several transmissions. That was on a 3.5L as well, which has a different CVT than the 2.5L does.

I had two CVT ACs before finally getting a manual Altima, and let me tell you, as one that has driven both, the manual is a completely different car for putting power to the ground (especially from a dig... the CVT cars are not very good launch cars.) The 6MT is just more tried and tested... the CVT development has a very long way to go to evolve into a transmission that's ready to handle extra power and hard driving. This is why you see 7ATs in the Gs and Zs instead of CVTs. Nissan knows that the CVT isn't there yet.

Agreed when you mod a cvt keep the stock parts that way if u do blow it you just swap them and then go in after

also turboing the cvt is a bad idea it sucks on the 2.5 i wouldnt even bother
