If it weren’t for those people with a lot of free time on their hands we wouldn’t get to marvel at such a mechanical masterpiece as this––a B15 Sentra (current gen.) with a VQ35DE engine. The VQ engine used for this project is the same venerable six-cylinder found in the Altima, Maxima, 350Z, G35… you get the picture. The VQ makes those cars fast, but it makes this car ridiculously fast. Try passing the traps in 12.9 seconds at 105 mph in a FWD pocket rocket normally restricted to 15.7 seconds at 88 mph.

Credit for the engine swap goes to a member of the SR20 Forum by the name of unlucky who eventually plans to offer his swap as a kit for not only the B15 Sentra, but the B13 (1991-1994) and B14 (1995-1999), as well. He’s looking for a donor car on which to prototype those kits, so if you’re insane and have $4,500 to donate to the project, you’ll end up with a Sentra whose front wheels turn to the tune of 250 wheel-horsepower. That's as crazy a combination as the 300-hp, FWD Caliber SRT-4.

[Thanks Dave for the tip!]

      I have a 2002 Sentra SE-R spec-v. Alot of miles on the car and the engine has gone to complete crap on it. Instead of putting in a fresh new QR25DE I was considering putting in the 3.5 and hooking it up to the 6 speed tranny I already have. I am wondering if that's even possible and how much work will that be?

      #3 your an idiot, unless you can prove me wrong with pictures of this unexisting swap, then your comment should be deleted due to massive stupidity.

      Whats up yall Im a member of www.thevboard.com . The owner of the above pictured spec is also. I have rode in his car before and let me tell you, IT MOVES. The swap is still in its infancy stages as far as getting a couple of issues sorted out but other than that its fairly straight forward.

      And to answer some above mentioned questions. The engine is out of a 04 Maxima. The VQ you use for this swap has to be one configured for front wheel drive, not rear, so you can use the VQ35DE from a Altima or Maxima. The swap only add's about 50 pounds to the front of the car, which is the same amount a turbo kit would add and it reuses the half shafts from the spec v, but it remains a front wheel drive car, not rear wheel.

      If you want more information on this swap you can refer to this thread on thevboard.com

      Impressive swap. Pity it's only good for going straight.

      i can see where RWD would be better for drag racing on a sunny non-wet day! BUT ... fact remains, FWD is totally better than rwd! i test drove a 350z fully worked up with nismo parts on a slightly rainy day (drizzling), i kicked the clutch in, tap the gas a bit while letting out the clutch and what do ya know, the rear end went side ways, like i was in a drift competition. A FWD vehicle with 280lbs of TQ. wouldnt be all over the place when the hammer comes down!

      I was thinking about doing this swap to my 2001 Altima SE. Any suggestions?

      This swap only adds appx 60 lbs. The shop has really turned their customer service around (in response to #6). This swap also is just as fast as any boosted spec v running the basic psi of 7.5 lbs generating 275 whp.

      #10. No this is the engine from the maxima which is also FWD

      Hey.. If the man who did this swap is still up and reading this blog, please give me some contact info. I have an 02 Spec V, and had fantasized about getting this particular swap done before I ever read this blog. The VQ35 is just amazing with it's low weight gain over the QR25, and amazing power. I want that in my car.

      nice swap i wonder if you can sweeze a turbo in there to maybe a top mount intercooler to save space and re rout the battry to the trunk for better wieght distribution

      Hell now that'S a ride.. where can I get one?

      Hello, Nice swap, I'm not too impressed cause I've seened dome something similar swapping a 3.2TL acura into RSX, here in the city, But I was just wondering perhaps the V6 altima front end would be a good candidate to install in the sentra. I don't know much about nissan's. It's just a thought that passed throught my head. I'm sure this car must have a massive understeer. Some rear weight would be good to balance out.
