Gearbox model numbers

Gearbox model numbers
I'm buying a LSD gearbox for my 5 speed conversion, I went out to have a look at it and I couldn't seem to find a model number anywhere on it, the guy gave me this code RS5F50V. I want to confirm the box is actually a RS5F50V
What box are you running? is it a RS5F50V?
The RS5F50V I'm buying is from a 2litre Cefiro but I'm hoping its and indentical box to the Maximas.

Is there a serial/model number eitched/engraved on the housing of the gearbox so I can verify it is indeed a RS5F50V. The plate under the bonnet that has the Chassis & Trans code is gone now as the gearbox is out of the car.

Nissan does not usually provide identifiers other than the VIN plate on transmissions. To know for sure you should put two axles in the thing and see if there is alot of differential restistance between each side.

I'm pretty sure its LSD just making sure its not out of a crappy Nissan Primera/bluebird or something.

Here's to hoping it's the same tranny though...

Just did a search. The RS5F50V is indeed a 5-speed manual transmission, so that guy got the number right it seems. It's listed under 1993 through 1998 Nissan Altima, which would be a Bluebird in NZ. Doesn't say what engine it was paired to though.
EDIT: Take a look at this link:

According to them, the RS5F50V is indeed an LSD tranny. The RS5F50A would be the non-LSD version. So you are getting an LSD tranny assuming the guy got the number right
The GTiR guys seem to like to use it for their projects too, so it must be pretty stout.

now if your just looking for the gear stuff inside, then i guess it doesn't matter

This is all why I initially told him he had to have the correct bellhousing. Nissan is still sharing tansmissions today between engines. The RS6F51H has a bellhousing for a VQ35 and the QR25 (Spec-V)

So he really shouldn't run into any issues then, should he?

VQ20DE has different ratios to the VQ30DE

I don't know how much cyro or shotpeening would be etc.. but if thats more viable than the 5th gear 3rd gear swap...

I rung up for a Maxima Clutch and the guy goes "Maximas don't come in manual"
So I can't get a whole A33 box very easily but was hoping could perhaps import from US just like the 3rd gear or something.

I don't think there'd be a problem fitting the 5th gen 3rd gear in the 4th gen tranny. It's basically the same ******* thing, only stronger. I may use brand new 1st, 2nd and 3rd gears from a 5th gen tranny when I rebuild my 4th gen trans. The 2-3 shift has double synchros, too.

I will check soon, but the guy said the parts themselves are not very expensive. What is expensive on a rebuild is the labor; taking out the tranny, opening it, rebuilding it, putting it back together, and back in the car. The parts must not be very expensive if we do the work ourselves.

I was at a track day and a chap told me that I was running seriously slower than I had to because of my gearing / gear ratios... The fact that I had to drop it into 2nd for slow turns, and only spent a couple very brief moments in 4th makes me think that I could get much much better acceleration from more aggressive (racing) gearing... Can anyone say what the options are in this respect?
Ideally I'd like to start in 3rd (from 7K redline in 2nd) and top off 4th around say 55-115 MPH..
Whereas I currently seem to be going into 3rd around 70 and the top of 3rd is like 100 MPH... Meaning that start of 3rd to top of 4th is currently like 70-130 or so... (Not that I have been to 130 )
How much more aggressive is the VQ20 gearbox? Anyone have the numbers? Anyone know of different options? (perhaps the xterra box??? Trucks normally have more this kind of gearing)
Im no expert about this stuff so keep the flames on low please..

i would think that the vq30 gearing is already aggressive considering that 3rd, 4th, and 5th are so short (look at your highway rpms, they are excessively high IMO). 5th gear at 75mph is at 3000 rpm, 3rd gear should get you to around 110 mph.
most tracks will not have turns that require less than 30mph speeds, meaning that 2nd should get you out of the hole just fine. More aggressive gearing means less top speeds also. Most ppl i've seen having more aggressive gear ratios (changing the final drive) is at drag strips
maybe you were running seriously slower due to your car setup, modifications, or do i dare say driving skill

I have shipped tranny parts to Austrailia. Customs was a b!tch.
