i was randomly thinking this weekend and i know to turbo the 3.5 is a *****. But i was thinking if u could sorta fit a sr20det in our 5th gens which im sure we can cuz there not that big and also what tranny would be able to bolt-on to it... Would our stock tranny bolt on 2 the sr?

 

No ... No ... No...

 

lol it was wortht he random thought

 

Why is turboing the VQ35 so hard? How much power do you want to make?

 

Just because the sr2det has more aftermarket support, does't mean it'sbetter to turbo than the 3.5L.

 

im just saying this since that turbo 3.5 from ssr has been going on 4 awhile, i just got the idea of an sr20 in a max....i know the sr20's can hold on power. Ive seen some sick se-rs...i was jsut wondering if any1 ever thought of that

 

im not saying the sr20 is better or worse then a 3.5 im jsut saying what if

 

Putting a sr20 into a Max would probably be harder than custom fitting a turbo on the 3.5L ...

 

I would rather have turbo'd 3.5L personally.

 

Do it man. Viva SR20.

 

People think of it all the time. They also ask about it every 2 or 3 weeks here, and get the same answers:

1. It'd be too much effort for the power you'd get
2. The power curve would be worse
3. It's easier to make power with a VQ35

 

Small 4 cylinder + big heavy car = no good.

 

Question.....how deep are your pockets?

But for real , anything is possible.....the boys at Zfever in Tampa are putting a SR20DET in a 240Z. So i will have to say it is possible with creative modification. But in the end i am sure if you did get it to work , your S20DET 5th gen Max would probally be no faster than a stock 5th generation Max.It would be only worth it if you were going to build the SR20DET up.

Much cheeper to add a S/C and tune it properlly than the route you want to go.

 

And sr20det into a 2,000 lb car is much diff than a sr20det into a 3,500lb car. Especially when the 3,500lb car already makes more hp than the sr20det stock for stock.

 

yup. this kinda reminds me of gay **** sex. things going where they were never ment to be put.
i think it defeats the purpose, putting a 2.0L engine into a 3300lb car.
kinda like a 4 cyl camry.
the sr20 was meant to be in a much lighter car. the fact that its so powerful when modded is a big bonus for centra guys.

 

In the camry's defense, there IS a factory turbo that will drop right into it. So that swap is not really out of the question. Would be an interesting swap into an older 4 cylinder version. Especially the AWD 4 cyl na version. I don't think the older 4 cyl camrys weighed in at 3300lbs though.

 

Yikes, man... ease up...

 

heh yeah, sorry. i just felt this was an appropriate coparison.
i also have a 99 v6 camry, and its very similar to 4th gen maximas.
engine output is nearly identical, so is curb weight, etc. i really like the car for what it is. the 1mfze engine is awsome, by no means worse than 4th gen maxima engine. too bad the camry does not have too many v6/5spd cars out there, or strong aftermaket support. it would have been a formidable competitor to 4th gen guys.

 

how bout a VE+T that makes this much power and its not tuned yet!

Can't really tell where the powerband is though. Yeah I could build a 1500cc F1 motor to make 2-3x that much power. Would I want it in a heavy chassis? Not really. 24lbs of boost?? Why not use 1/2 that boost and get the same numbers WITH torque in the low rpm range? But go ahead. It's not my car.

 

im with you i wouldnt do it either, but the SR20 guys in fla are nuts!

 

SR20 is designed to rev really high under boost. it's perfect for racing applications. to put that into a 5th gen would be pretty insane. in a sort of retarded way. however, pondering it, and being that the 5th gen is FWD, you'd need to get the n/a FWD version, with tranny, of the SR20 out of the G20 Infinity, then turbo that.

then, once you have that, you have to mate up somehow the half-shafts of the G20 FWD drivetrain up to the Maxima. you would need to custom-fabricate a way to have the SR20 half-shafts work with the Maxima knuckles/ spindles. for that matter, you'd need to actually use the entire driveline/ hubs/ axles/ spindles of the G20 and put them onto the Maxima.

then you have a dilemma because the G20 is 4-lug. so, then, you'd have to do a 4 to 5 lug swap. and i don't really know how G20 guys do that swap, but i'm sure there are threads and forums out there about that.

THEN you must build up the SR20 in order for it be worthy of pulling the 4000lb 5th gen Maxima pig boat: you'd have to probably tear down the SR20, port it out, and put a stroker kit in it for the engine to even "matter."

you'd have to have at least a 20g size turbo, and that will necessitate upping the fuel injection to around 770cc. you'll need fuel rails for that, as well as a SX FPR type of setup with an SAFC. you'd have to basically set the car up as a pure race car for an SR platform to make any sense --with downpipe, FMIC, tranny cooler, oil cooler, bulletproof tranny gears, wiring harness, the list is endless. you'd spend $30k easily.

were it me, i'd take a G20 and just turbo that. you'd get more power with less modification. and you'd have one sweet ride. and the drivetrain and chassis would be perfectly balanced --true to "tuning."

 

2003 maxima se: Curb weight 3,220 lbs (from cars.com). this is with the 3.5l engine.
but i still think its silly to put a small engine like this into a max.

 

It's all about torque, guys. Jeff92se said it perfectly: smaller engines can make however much power you want, but they'll do it all with revs and it'll all be on the high end. Bigger, heavier cars need more progressive and linear power delivery.

 

bonzelite destroyed anyones hopes of putting in an SR20

 

Actually don't they make FWD SR20DETs? I see them in sentras etc.. all the time. The SR out of the Sunny GTI-r for instance.

 

FWD de-Ts came out of the nissan bluebirds..the older altimas that we have in the states. the gtir came out of the 4wd PULSAR GTIR, that came with a gigger turbo(t28) 444cc inj, lower comp, and diff intake manifold and some other crap i cant recall...

Wow what a random thought!!!

Yes they make FWD SR20DETs. They are in the GTi-Rs and in the Bluebird SSS ATESSA (AWD SR20DET 1st gen Altima).

Would it be worth the trouble in any way, shape or form? No

If you started with a smaller car with either an SR20DE or a less powerful engine then yes you might consider it. Doing it in a maxima would be stupid. I would rather do a VQ30DET swap in a 240SX or an old Z or something that would actually be fast.

 

chronos --"2003 maxima se: Curb weight 3,220 lbs (from cars.com). this is with the 3.5l engine. but i still think its silly to put a small engine like this into a max."

yes. the max is still too heavy for a high revving, short-stroked engine like the SR20DET. it is true, though, that shorter-stroked engines can potentially produce HIGHER peak HP than longer-stroked ones, but sacrifice low-end torque in the process. and you would want good low-end torque on demand to pull that 5th gen ahead quickly.

dood --"It's all about torque, guys. Jeff92se said it perfectly: smaller engines can make however much power you want, but they'll do it all with revs and it'll all be on the high end. Bigger, heavier cars need more progressive and linear power delivery."

-correct --what i elaborated on above. the SR20 is about high revs, as i said. as this is often the crux of the "KA v SR" debate, ie, why some opt to turbo the KA, as it makes more torque = fun.

jeff --"Actually don't they make FWD SR20DETs? I see them in sentras etc.. all the time. The SR out of the Sunny GTI-r for instance."

no USDM SR20DE, GA16DE, or QR25DE (SE-R) Sentra ever came with turbo. but, jeff, you are correct about the GTI-r. regardless, whomever still wants the SR20 in the 5th gen, i would simply forget it.

He was mentioning the DET version. Which you can get from Japan that were in FWD configuration. But the title of the thread mentions only SR20. Sort of confusing. But we will assume he ultimately means sr20det.

00-01's are VQ30DE
(not sure but I read somewhere that our torque was 212 instead of 217?!)

 

sure. SR20DET. it is confusing.

but regardless, a stock SR20DET is too torque-weak. even the mighty GTI-r with 205 lb/ft of torque is a step down. you'd have to build up that engine.

and the other factors for the swap, like wiring, and engine mounting, and axles, is just a wall of discouragement. unless you're Jay Leno.

 

[QUOTE=AcerX]thanks for that correction. my bad.

still doesn't make an argument for the SR.

 

They never made a FWD DET. They were AWD.

 

Yes but they were transverse and could easily be mounted in a FWD configuration with a normal SR20DE US 5 spd tranny.

Bottom line:
Is it possible? Yes
Would it be worth it? No

An RB swap would be a different story.

Swapping anything besides a VQ into something that has a VQ in it stock is stupid. The SR has a lot of aftermarket support, but you would have to take full advantage of it just to get it to a comparable modded VQ. Any other discussion about this has probably already been covered in at least the thread I posted earlier if not in 10 other threads about swapping some other engine into a maxima that doesn't belong there.

 

It's been done for the 350Z so it can have more ummph to drift. It was a silver one with red things on it.

For the Maxima, it is very pointless unless you like going slower.

 

Keep the 3.5....put a turbo on it...I bet it would be the same price....sr20 in a max=

 

Why not yank the 3.5 and put in a 3.0 from an 00 or 01 Maxima. It would be an easy swap and there are several forced induction options for the 3.0. You could probobly find someone in the All Motor forum who would do the swap just for the motor.

 

how bout an M45 engine in a 5.5 gen lol jk

I have a 4 cyl camry, and I hate damn near everything about it from handling, engine response, acceleration, braking, the interior etc.(i only like mileage and reliability)

 

now that is underpowered. wow. 4cyl in a camry? i bet the sticker price was pretty low, though. you can always think of turboing it.
