But if you can’t handle the power of the VG then get outta the kitchen.

Someone with a 5-speed 3rd gen could simply open up his transmission and change the base/bellhousing portion for a VQ part, and keep his trans internals and upper case. You keep the same axles, just need to fab different motor mount points and then it's off to the electrical part of the swap.
SE-R Sentras doing the VQ35 swap do the same thing except with 6-speeds. They keep their 6-speed and axles that bolt to the QR25, but swap out the bellhousing for a 6-speed VQ bellhousing. The same thing is possible with the older 5-speeds, parts are interchangeable, whether they have a VQ30/35, VG30 or KA24 (93-01 altimas) bellhousing. All three applications use the RSF50 trans, hell I even had more aggressive 1st and 2nd gears from a 2001 2.4L Altima.

I would like to see someone take on this swap. It would be cool to have a VQ35 and the IRS in the same car. The swap would without a doubt help with handling too - the VQ35 is 35 lbs lighter than the VQ30, which was already 108 lbs lighter than the VG30. So 140+ lbs off the front axle would certainly help the 61/39 weight distribution. Not to mention you can set the new engine lower while you're making the custom mounts.
And believe me the swap is worth it. I went from a stock VQ30 to a VQ35 with headers and the difference was unbelievable. The VQ35 is capable of 260-270whp with just bolt ons, a better intake manifold, and good tuning (i.e advancing the crap out of timing).

the bellhousing is not removable!
you are talking about the front half of the case
while that may be interchangeable with other manual trannies it is still not a bell housing and requires a LOT more work than swapping a bell housing

I clearly explained what I was talking about in my previous post. Anyone seriously interested in this swap can take it or leave it as they will.
"A lot of work" is completely subjective. I had never opened up a transmission of any kind before opening up my 95 trans, and I can go from a complete, assembled transmission to having it completely disassembled with that front half/base/bellhousing/whatever portion in my hands and empty in less than 30 minutes.

NOOB Question - If you swap trannies completely requiring new axels would you have to also switch hubs and brake components. That may be the reason why swapping bellhousings will come to be a cost saving method too.

But if we want a newer tranny we just have to put every thing but the newer bellhousing/trannyhalf w/e....hmmmm...new tranny...hmmmm..../homer

You guys, I know the reason you would want to swap the bell housings. The bell housing portion bolts to the vq and the other side (casing) bolts to the chassis. This would save time fabricating tranny mounts and the 3rd gen axles should work so you wouldn't need new axles.... Did my posts not make sense?? I agree with you guys on what your saying??

The 3rd gen tranny does not bolt up to the VQ30, that's why you need a VQ30/35bellhousing to do this. In this case all the swap would physically require is a slightly different crossmember and a different passenger side engine mounting point. It will physically fit for sure the VQ is a very compact engine (It's basically a 2 foot cube).

ok..im going to say this as clearly as i can, cause i dont think im being understood.... A VQ trans has the mounting points for VE and VG trans mounts to be bolted to, meaning all the bolt holes are cast in and threaded that the 3rd gen mounts need to bolt to(at least all the VQ transmissions ive seen do). A VQ 5spd is basically the same exact casting as a VE/VG casting, it just has a few more bolt holes cast into it for where the 4th gen mounts bolt to, but it still has the ones that the 3rd gen transmission mounts require.. Therefore in order to put a VQ into a 3rd gen, you would use an entire VQ trans and just bolt the 3rd Gen trans mounts to it. Engine mounts would be the only thing needed to be fabricated. Ok.. i think that explains it ok. Im sorry im a bad explainer when typing.
