engine swap

[ramarte1959]

hi could someone tell me if I can put a 3.5 engine on my 2009 2.5 altima coupe has anyone done it? thanks for your answer.

people are always quick to say just trade it in. I don't agree with that. I think everything should be given a chance. to do some research and see which route is best. in this case, the 2.5s and 3.5se have a different engine, different transmission (if its CVT, theirs 2 different CVT transmissions) then the entire suspension is different, the ECU of course is going to be different. plus labor to have an EXPERIENCED shop do something like this will be crazy since almost no one is experienced in messing with CVT transmissions. plus you'll lose your warranty, you wont have some of the standard features the 3.5 has unless you have a fully equipped 2.5. when you calculate everything, it really really really is NOT worth it at all to do this. you could try a Turbo system if you have a manual. if you have a CVT, the transmission wont take the power and you'll blow your transmission (its already happen to a member with a white coupe from Florida).

If you do though, choose to go against what they advised you and you do get a new engine, I can sell you a 3.5 CVT transmission, ECU chip and the wiring harness needed for it, at a good price. They only have 13,221 miles on it to be exact. I have this because I just did a transmission swap to 6SPD, for the turbo getting put on my car atm, btw I won't have the transmission,ECU, and wiring harness until next month (mid).

you converted from a CVT to a 6spd?? how much did that cost ya pm me

so you're the mystery person everyone has been talking about! how did the conversion go? does the car drive like a normal 6 speed or is it different? how much did it cost? etc...

I really can't tell you because my car won't be finished until next month and unfortunately i'm in afghan and won't be home until around Oct 1st. to drive my car. But as soon as I get home I'll keep you updated on how it drives. As far as the pricing went it cost me 3,500 and I get to keep my old components they are taking out. Also, the shop that did this for me just so happen to have a 09 coupe laying around with like 1k miles on it some guy loss to them, so the xfer is pretty easy for them, they're just moving pieces from one coupe to the other.
After they pick up my car on Sat. they'll start sending me pics of all the work they're doing and I'll keep everyone updated.

Sounds just like when Blake had his turbo installed. He was deployed as well and not able to enjoy it till he was CONUS. Good Luck out there and stay safe and Thanks for doing what your doing for us Civi's back here

Did you consider trading your car +cash for the one they had? Could have saved all that money on labor.

[Still-Breathin]

I could never trade my baby for another coupe, I love muh baby =D. An thnx dude i'll try my best to get back safe.

I remember the thread on this, saying the swap was next to impossible. But wow, I would have guessed it would be a lot more than $3,500! Actually, that leads me to another question, was that parts+labor or only labor? That's actually not too bad. Do you know how long it took them to do the swap? I talked to my mechanic about doing a transmission swap and he said "It's never a good idea" and his shop works on most anything from American Muscle to Civics, SRT4's and GTR's.

So this has me curious since I was "considering" the process.

Oh and to OP, the engine will fit I'm sure since the engine bay/chassis is the same, I don't think that's an issue, just an issue on how much money do you really wanna spend is all.

[Still-Breathin]

I'm getting alot of work done to my car, so price my vary if you just get that done. As far as next to impossable, I don't see why? To be honest with you, if you have the money you cab do anything to a car, you could my the coupe all wheel or rwr wheel drive if you have the cash. As far as CVT to MANUAL nothing is really changing but the transmission, in fact I would imagine it would be easier to go from CVT to 6pd considering the 6spd transmission is actually lighter and slightly smaller, so fitting isn't really an issue. I don't know, though why he couldn't do it.

[Ranga14]

I believe he could do it. I just don't know if he thinks I'm serious or not. I haven't really done any SERIOUS work yet. All stuff that's fairly cheap and bolt on like, pretty much all the normal bolt ons you can get for the 3.5, I've got and done myself or had him do with the exception of the BBK. I'm sure if I threw a wad of $$$ out then he'd change his tune, lol.
