Rwd Sentra

[Psa1sonic]

Well im an engineer student and i want to make my 03 se-r sentra rwd or possibly awd god willing. Now from my understanding the sentra and the Frontier have the same block ? the 2.5l motor not shire on the engine code i think its q25 somthing? Well i was wondring if any one knew if the frontier transmission would be a direct bolt on or not to that block. cause if not then well i get the fun of taking not only a frontier apart but the sentra as well. Witch i was going to o either way. but my orgional plan was to see if i couldent find a jdm setup and bolt it on to the transmission. My plans have been drawn up and from the measurements i took off the frontier. and well the entire thing will fit with a bit of love from a hammer a torch and some swearing. and my orgional purpost for this is well who has a rwd sentra kinda neat rolling up on a ricer and being able to sit sideways with no ebrake.

No, the Frontier comes only with a longitudal VQ35DE, which is in no way related to your transverse QR25DE. The only way you could do this is with a very expensive custom transmission.

Just buy a RWD car.

he could do like this guy did with a lude

ahh this is the infromation i wanted to know so that mean i just take the motor out of the nissian frontier and all the gizmos and gadget and put them on the sentra only thing really special is mounts some body workand custom drive shaft.

Bacause i have sevral rwd cars and im doing it more for the enginearing challenge

[nametakennow]

No, you can't just pop in the motor from the Frontier. It's completely different. It's a V6 mounted in the opposite direction. You'd be lucky to fit it in period., much less have enough room to fit a radiator, transmission tunnel, etc. You'd also need a completely custom suspension.

no not the v6 motor the i4 and yes i under stand all of thease things i know it all hase to be custom fabricaited hence why im doing it im also it more of the challange i dont really care if the car ends up doing crazy amounts of hp this is more of a unique car not race car

After a little more research, I've found an 05/06 2.5l I4 model, but even if it is a QR25DE (which it may or may not be), it's longitudal, and it'd be a tight fit at best. You're welcome to try, but you'd better have a lot of money and/or fabrication experience and equipment if you plan on actually driving this car anytime soon.

edit:

On second glance, I can't be completely sure that engine is longitudal. If it is, then you just have the transmission to swap/deal with.

yes yes this is more a fun thing to take slowly im not gonn rush it iwant to make shure all will fit yeah this car will be totally custom and yeah i have pleny of torches to do it with

[Rival SE-R]

why limit yourself to the frontier engine? to do what your talking about you could actualy use anything... the majority of the work is going to be involved in redesigning the unibody to accept a longitudal engine and trans, a drive shaft, a diff housing, and a rwd rear suspension set up... also finding rwd front knuckles and hubs that will fit your sentra... the electronics and wiring woes that normaly burden down a engine swap will be butter compared to those issues... it might be easier to just build or modify a frame to accept the sentra body honestly...

easier, and more beneficial in my opinion, would be to make it midengine transverse mounted rwd... but this will still require alot of work... including strengthening the rear half of the unibody to accept and engine cradle, and re-engineering the rear suspension of the car pretty much all together...

anyway you look at it its going to be a major undertaking... i would recomend talking to mirageforums guys who converted thier cars to awd... and tuners like bill schimel (vw tuner from pa.) who has very succesfully converted fwd cars to rwd...

for what its worth i have thought about this before myself with a b13 chassis... but have yet to see a fwd converted to a front engine rwd without a tube chassis... not that a tube chassis isnt a beautiful thing lol-pete

[Psa1sonic]

ah ye ye but im not looking to make this a total race car looking more for the sentra weight distribution and ride characteristics. yeah it will not be crazy high way fast but it will have enough torque to get what i want accomplished. more bragging rights than anything else

[SgtDGun]

probably use the 240sx indepedent rear since it has a complete cradle, and to save money just use the whole KA24 drivetrain and computer.

[SpecVDan]

better idea

go buy a g20 (p10), get the t4 models rear suspension and driveline. drop in a sr20det, disconnect the front drive shafts, and bam. no custom modification.

on another note, you could tube frame the sentra, then you could set it up for whatever drive train you want... thats a bit more work...

[VMPhil]

There is a guy in lousianna (i think he was moving) who is currently performing VQ swaps by the name of Travis. there are some track footage on street fire i think.

also no there is no way to convert a sentra to RWD unless you have very deep pockets.

Or a welder and a few plates of steel and a Z or a 240z rear subframe.

You'll need to cut the firewall, floor pan and part of the trunk and weld in plates to fit in the transmission, drive shaft and subframe.

This would amount close to a tube frame race car setup.

Once it is done, you'll have a Nissan version of the Toyota Altezza.

holy back from the dead lol

holy back from the dead lol

'

haha for real.

[northhoustonser]

no frontier has ever had a vq35... they have a vq40 v6 or a qr25de.... the older frontiers have the ka24de or the vg

[graphicdude]

Whatever you choose to do, it will be awesome, jsut make sure to post up pics once it's done

Yeah, he's cool and his swaps are pretty clean from what I have seen. And to the dude who thinks this is a simple "engineering" job to tackle: The engineers at Nissan designed the whole car around a FWD layout. You would literally have to custom fab everything. EVERYTHING. So that being said, you need about double what a Sentra is worth to even get started. A few guys on thevboard have talked about this and it would actually be cheaper and easier to convert it to AWD than RWD. So, in short: dont waste your time, pick a different project for your engineering challenge...sorry if that seems negative, but Im just keeping it real.

... you mean in the year this thread has been stagnant, nobody has considered meantioning the X-trail, AWD compact SUV, driven by a qr longitudinally mounted with IRS??? i think its the same width rear and front track, comes in 5 speed... so who here actually knows the nissan lineup

Any change in the drivetrain of the Sentra offers mostly the same problems. The engine bay is not very long, and while there is a hump in the floor for a transmission tunnel/driveshaft assembly, the firewall would have to be cut in order to put one in, on top of the use of custom mounts.

People have talked for years about converting Sentras to AWD (and, occasionally, RWD), yet there hasn't been a single running example, just a whole lot of theory as to how it would work. The X-Trail and the Pulsar offer the best possible routes, since they do offer transversely-mounted SR20's, which are the easiest swap in, and are the most related to Sentras.

Well, scratch that, there was an AWD B13 in Japan. It was an OEM model and explains why there's a hump in B-chassis floors. I haven't seen one brought to North America. That would actually be the easiest method, but, again, it hasn't happened.

RWD, on the other hand, would be entirely custom and, IMO, pointless.

thats because the X-trail has been mentioned in countless other threads across several Nissan Sentra related sites for people trying to convert to AWD and has yet to be feasable on a cost per result basis. basically no one is willing to plunk down the Money for the parts and custom fabbing. The X-trail would be the best way to go for an AWD set up but alas no one has even attempted.

[Charles J. White]

What if you found a damaged X-Trail and remove the body from it and replaced it with the body of a Sentra? Would the Sentra body fit over the frame of the X-Trail? If it could, all you have to do is play around with suspenion related work would you not?

[nametakennow]

No, it wouldn't just pop on there. It'd still be a wiring nightmare too. They're related but heavily different. Also, there are no X-Trails in the US, where most of these conversations take place.

[slickslik]

i want to make my p10 rwd or awd what could make this possab le

[nametakennow]

It's extremely expensive and, insofar as I've ever heard, no one has managed to get one running.

It seems that the best option is AWD with a Pulsar GTi-R drivetrain, but, again, it's very expensive to even attempt.
