QR25 swapped 240

[alms24sebring]

Know of any? I was thinkin about this, a torquey revving T28 sized turboe'd QR25, in an S14. Simple as that, or is it? Id like to see the write up to that. I think the hardest part would be getting a trans to fit, but it might be strange enough to work!

[pepesilvia]

just out of curiosity, why the interest in the QR25? isnt that the motor from like a Rogue? I dont think that motor is very fast... you'd probably have just as much output strapping a T28 to the KA. Do they make a RWD transmission for that motor? seems like a lot of unnecessary work.

I've actually thought about this before also. 175hp, 180tq makes it more powerful than a stock KA. a tuned up RWD QR is what I imagine them putting into a BRZ competitor. A QR25 s-chassis is in Impreza 2.5RS territory.

Now if you imagine turbocharging that, I feel like the results will be pretty good. Mate the QR25 to a KA 5spd and use an s14 or s15 sr turbo. You'd have to do your own tune etc, because I don't think downloadable tunes exist for the QR, but its possible.

[alms24sebring]

^ Thats exactly right. After 3 months with my Spec, Ive really grown fond of the QR. Lots of low end torque and sounds... great actually. I really like the thick powerband and its sensitivity to handling and if you ask me. Anyways, its almost better than a KA in my mind in almost all ways, its just facing the wrong way. Base turbo with a few add ons and a (good) tune as always, makes 300-320 hp AND tq. Like I said, finding/making an adapter plate for a trans to fit may be a problem. QR -> KA trans ?? Also I imagine the wiring is probly the biggest whore along with mounts, header, piping, A/C would be baller, etc, to fit in an S14 shell. Alittle time and effort on the side and you've got yourself a powerful Nissan thats different.

There are good tunes available, mainly for the 04-06 ecu's (have to modify 02-03). 2J Racing tunes ecu's with Osiris and UpRev. There are a few chips and different levels of ecu tuning to choose from. They offer a mail in tune where you tell them what you have as far as parts, and you mail in your ecu with a list of what 5 tunes you want. They have something like 40 maps to choose from. From gas sipper economy tunes to max hp tunes. God I wish I could spend money right now!

I hate daydreaming...

That will be a major swap, i think that it could replace the sr,if someone could prove it to be done

[PapaSmurf2k3]

RWD QR in the Frontier... with a 5 speed.

Why anyone would want to replace a KA with the QR timebomb is beyond me though. Maybe with enough polish, you can get a shine out of that turd.

[jbracy7]

Papasmurf why dont you like the QR, the ka is geting old,parts are dissappering ,fanboys are blowing them up faster,than a whipits bollon in 95

wahahaha that made me laugh. I guess i can see where you guys are going with this, although i'd still never use my time and $$$ towards a swap that would only be a little better then the stock motor in my car. It WOULD be interesting to see if it could be accomplished.

[simmode1]

I would rather spend my money mating a 350Z 6spd trans to the proven/cheap KA and boost it.

[krash]

My thing is, when KAs become less and less common, this could maybe become a viable option. Then again you could probably just go VQ and call it a day also.

I miss the days of the $200 complete KA with trans.

[alms24sebring]

Yeah you never see good prices for KAs. I think its interesting, even n/a (but probly wouldnt be worth it). I dont know why everyone hates the QR. From the factory in the sentras.. yeah it is a timebomb.. but replace a few parts and fix a few recalls, its all good. Also a costom intake manifold will have to face the other way so after thinkin about it it would probly be pretty dam costly just to make it fit. But if I had money to throw around and alittle more craftsmanship, anything could be done.

[PapaSmurf2k3]

But at the same time, you could swap something in that doesn't suck from the factory. Engines you don't have to "replace a few parts and fix a few recalls" with.

[krash]

I guess its just an interesting idea that sounds good when I think about it. Low mileage QR shouldn't be too hard to find right? But by the time you hit the final cost, you could probably build a badass KA and turbo it.

[alms24sebring]

^ ^^ I guess both of those are true. Both engine killer recalls would be replaced with aftermarket parts anyways (precat header and butterfly screw in the intake mani that back out... Can be simply locktight'd in if anything.)

QRs are plentiful. I guess overall KA would be a better choice for more than one reason. Money #1, amount of work as in its not like theres a write up on it, so everything needs to be figured out, sourcing custom made parts, and a place to let the car sit for a few months. Neither of which I have lol, but I think its a cool idea.

[simmode1]

Then again you could probably just go VQ and call it a day also.

Man, I don't even wanna talk about a damn VQ swap anymore. I used to love those motors, but they are such a headache to swap that I'd rather go SR or 2JZ+CD0009 trans.

[10psitx]

For me... it always comes down to bang for buck....money spent as opposed to gains, is it worth it in the end. So with that said SR swap will always be decent return on investment both HP and resale.
Lots of people want to be different so if that your thing go for it, go to an auction site that sells to the public like AIA auctions and buy a wrecked 2010 and upward nissan frontier. They come with the QR in RWD setup, fab engine/transmission mounts get a drive shaft made at your local machine shop and install your QR. You will need to source the FSM to convert the wiring harness. drive it aroung in stock form and post your experience here....it would be a very interesting read.

[PapaSmurf2k3]

I'd rather swap an MR16DET.

God, anything but the QR.

[krash]

[alms24sebring]

Nothin wrong with the QR

[PapaSmurf2k3]

There's nothing really right with the QR...

[alms24sebring]

Eh, almost every motor has its own unique downfall. It has great potential IMO, just depends on what your looking for I guess.
