Would an 2005 altima se-r engine work in a 2003 maxima? If it can, what would have to be changed or used. If it can't, what would make it work. Thanks.

 

it should be a relatively direct swap...

 

but it wouldnt be worth it.its mostly ecu tunning that makes it higher hp

 

Engine wise there is no difference. Thus it would be very easy, but pointless.

 

Yea I think the xtra horses came from ecu tuning and vtcs like the 300hp zs and the 298G35. Would you really wanna do an engine swap for 10hp-15hp anyway?

 

Not to mention the camshafts and rod bolts.

VIAS power valve is plastic Lighter

 

I blew my engine, so right now NOTHING IS POINTLESS TO ME. I found a motor for $1600, but has 11,000 miles....and we all know nissan's 02-03 maxima engine's were overated...I just had the thought in my head, and wanted to know if it was posssible.....someone told me the se-r engine has egr's tho...So I would have to plug all of those up.

 

egr's would make sense as the 6th gens have egr

 

SE-R engine = A34 engine. There are differences in the part numbers of the heads and intake manifolds. Valve springs are softer too which frees up a few HP. A34's are putting down more power mod for mod than A33B's.

But i agree, it might not be worth it to swap.

 

10 char.....

 

Ooooo...that's why i get for not reading..




In that case, either the 6th gen motor or the SE-R motor will do.

 

I might be screwed as far as parts tho.....I have hotshot headers, UR UDP, Injen short elbow intake,......I don't even know if those would be able to transfer over....I think it would be worth it to me if possible tho...My engine is blown, it's either I get a nissan motor with good milage for $1000, or shell out an extraa $500-$600 and get an se-r engine...if of course it would def work....

 

they should tranfer over..u can reuse parts of the old motor to make some of that stuff work

 

I always wondered just how much more work it would take to swap with a A34 motor. If I was going to swap I would want to do it this way.

 

At the end of the day its ur choice but fyi an 02-03 engine will cost u half the price ur gonna spend on the se-r. I am sure those parts should work tho if not sell em.

 

I know you know, but just to clairfy.

To reap the full benefits, you will need to use A34 ECU.


Though I'm not 100% sure, but with that said, you could possibly even use a Z33/V35 ECU since they(z33/V35 ECU's) have been shown to be compatible w/ the A34(plug and play).

 

I have a good question to slide in here. Everyone knows that if you want all the power then you are going to have to get an A33B or A34 ECU to control VTC. My question is if you go out and purchase an A34 engine then how will/could/*insert other word* the A33B ECU control it? The A33B engine/ECU uses the exhaust cams as the EGR system versus the less complex electronic controlled external EGR of the A34 engine/ecu.

I ask this because I need to know (if I ever do swap) if I need to be specific in which engine I get. Clearly the tuning and engine upgrades in the A34 ECU/engine make up the few extra ponies, but the real deal is complexity and time. The A34 ECU is 500 times more difficult to throw into our A32 cars. That really wicked thread that I created a while ago with the pin-out differences between the A32, A33B, and A34 proved that the A33B ECU more closely resembles the A32 versus the A34 resembling the A32 (as can be expected with added complexities in newer cars ... and the farkin' CAM system).

 

CAN, for more clarification. IByoureanitpick


IMO...
A33B ECU + EMU/B should b fine.

 

"CAM" was a typo .... I meant CAN

I think you misread the question so I will just shorten it to one sentence. Will the A33B ECU control the A34 engine? And if so ... what codes would pop? I am guessing just EGR.

 

You missed my point.

Just use the A33B engine, A33B ECU + EMU/B and call it good. Leave as many variables out of the equation as you can, while still retaining tuning and power options.

The MAF wring is different and I'm sure there will be more. Also, depending on what year A34 you'll be using, in 05 IIRC they went to wb-02's.

 

Oh I gotcha. Well then you implicitly answered my question. I asked, "Do I have to be aware of which 3.5 engine I get" ... the answer is yes because the A33B engine will not be too happy with the A34 engine as you just said.

Another question. The A33B/A34 have 4 O2s / A/F sensors. 2 in the Exhaust manifold and 2 in the Y-pipe. On a side note, they do not have a downstream O2 sensor.

Clearly purchasing a WB02 or plugging the downstream is solution #1, but what do we do about the O2s in the exhaust manifold. Just simulate them and call it a day? Get bungs welded on the A32 manifold?

 

I would go with headers in my case and use the primaries for plugging into the manifolds (in my case headers) and simulate the 2ndaries.

 

How did the engine blow?

 

Apparently no oil....I changed oil 3 weeks prior, but the night of I had a picture on my dash, and that caused me not to be able to see the oil light when it came on. My engine is knocking from two different places right now, so I figured I would just get another engine, or think of something INSANE, like an se-r swap.....I think ima just get a 2003 motor and get some ebay cams and call it a day....

 

So in the case that you use the A32 exhaust manfold and the A32 Y-Pipe/Aftermarket Y-Pipe, then you would place the 2 primary sensors (Normally in A33B/A34 Exhaust manifold) in the Y-Pipe and simulate the secondaries (Normally in the A33B/A34 Y-Pipe).

Obviously throwing in a WB02 would be the best addition afterward.

I couldn't tell you what a WB02 looks like. Would it fit in the downstream hole in the A32 Cat/B-Pipe?

 

I wouldn't go that far and say it's insane . Also, the oil light is an indicator of low oil rpessure, not oil level.


I would say that sounds about right. Still, headers > * for a 3.5L IMO.


Along with something to control the a/f a bit better.

Wb o2 looks like a narrow band.(normal o2 sensor)

 

Headers are > * with a 3.5, but $$$ > -($$$) . In english, money is greater than no money. LOL.

Excellent about a WB02 looking like a narrow band. That means no paying some dork to weld on a bung.

 

3.5 4th gen y pipe> 3.5 4th gen w/ headers IMO.

 

Is that what you meant?

 

Aftermarket headers include the y-pipe ... how can a y-pipe be better if you still have unequal length exhaust manifold?

 

It's not better, that was just his opinion....

 

Yea I said IMO. No most old school 4thgen guys bought the y pipe w/out headers, when budget and warpspeed first came out. They were always on backorder and for good reason. After 3500 it was like the max had vtec. LOL

 

 

I am having troubles reading your smilies Nismo. Does that mean "yes" or "you are an idiot scrhale no"

 

Ummm...im trying to tell you something without giving away

 

You do?

The only major thing that might be different is the VTC map at partial throttle due to the external EGR. I doubt the WOT VTC maps are any different and the ignition timing can always be advanced with an EU.

 

..

A33B ECU + EU..

 

I think it is now safe to announce to the .ORG community that the absolute easiest way to use 3.5 Engine AND ECU is to get an engine with EGR controlled by exhaust cams (Any under 04 I believe ... I know 02/03 Maximas, but what about Altimas and all that).

With any given engine with internal EGR, then using the A33B ECU, gauge cluster, main harness, gas pedal, and power steering pressure switch should yield a perfectly working car. This is of course ignoring the O2 sensor hell (simulating and all that fun).

If people seriously desire the extra few HP from the A34 engine/ECU then getting e-Manage Ultimate should cure.

Hehe ... some of this information should be placed into the 3.5 FAQ. The FAQ makes it sound as if it is complete hell to get this done since JClaw attempted this with Altima parts versus A33B parts. Can we get an agreement and motion to have an official list built of parts needed for the full 3.5 swap and be placed in the 3.5 FAQ or a new sticky? I think I listed them all already, but I may be missing some.

This should knock out a lot of new threads of VTC and Full 3.5 swaps.

 

You still need to adapt the crank timing ring if you are not going with a VQ35 flywheel or flex plate.

 

The thread you started and that eng92 and i posted back and forth in is already an excellent start for anyone seriously considering this route. I have the feeling that not too many people will ever be interested in it though due to the extra labor and expense. But if they really want to get an idea of what it takes, that thread is it.
