I made a baaaaaad miscalculation.

The drivers side driveshaft which I had written that you need to use interior shaft from NX2000 and exterior from the G20 is ok BUT you must have this machined custom with an added 3/4 of an inch.

The reason is that the NX2000 is not as wide as the G20. With the shaft to short you'll drive around but if you turn sharp and hit a bump at the same time it'll come apart at the universal joint and probably roast your tranny.

This small miscalcualtion has costed me 2 trannys and 4 cv joints. I feel like an ass now, a poor ass too at that ;) Oh well lesson learned :)

Just thought I'd let you know in case someone else dares this project ;)

Can't you just switch a manual tranny straight from a manual g20 or primera?

You can but I wanted the VLSD so I got a tranny from an NX2000.

Ohh good reason! Learn something new everday :D

I hope you learned your lesson and dont break any more tranny's!:eek:

Which halfshaft (not CV joints) did you use? NX or G20? I'd guess you used the NX halfshaft and not the G20 one. I'll bet the G20 one is longer.

Just a WAG.

Well the part that goes into the tranny is from the NX2000, could'nt use a G20 one (man or auto) because the splines aren't the same, the exterior shaft is from the G20 and that is the one I extended 3/4 of an inch.

Yeah I don't want to break anymore tranny's.

This lesson cost me:

1600$ in transmissions
200$ in cv joints, grease, boots
200$ in towing.
100$ for custom shaft.

2100$ poorer but the car is running great and is now ready for DET.

What a morphed car, it was auto with no VLSD

Now its Manual with VLSD and DET coming in March. :)

man this is one serious tuner G. :D hehehe. hope you get the turbo in soon. :p

The complete halfshaft if composed of an inner CV joint, the actual halfshaft itself, and an outer CJ joint. The inner CV joint for a non-VLSD gearbox is longer.

Im really thinkin about switchin over to stick from my slushbox...and I know its been covered before and its a bitch.

But for opinions here, is this something that you need to do yourself? Or trust a mechanic to doing this. Would an infiniti/nissan guy know exacatly what to do? Or would you hafta supervise...etc...

Hows it handle? Do you notice a diff with the LSD? :) I bet its sweeeeet

First of all NO DON"T GO TO NISSAN/INFINITI!

When I was researching this project they told me it was impossible and would never work.

You could trust a good mechanic with this work but make sure you have all your parts. I did it myself with the help of someone who had a little more experience and it originally cost me 1200$ in parts + 3days of my time.

I did a little write up on this a while back, cut it short because of the problems I was having but thats worked out now. It really is a straightforward conversion.

...and yes VLSD is great especially cuz its winter now and 2 wheels gripping is always better than one. Also I noticed many dramatic differences with the car since its manual, I found I could really take advantage of the handling compared to auto which was too sluggish to show you what the car could really do.

Yeah I tried that (hence the 4 cv joints I bought) but the problem is the splines on the end of the rod that goes into the transmission aren't the same neither in quantity or in size (the hole for the NX2000 is smaller than the G20)

Hmm, I switched to LSD and never had this problem. Matter of fact, right now my drivers side axle is an un modified Auto G20 axle. Straight up, no changes. Works great. I've had both a NX and a SER tranny in there. Never had an axle or joint problem that wasn't the direct result of something stupid I did.

Watch the DSCFXXXX movie series, that's me in the G20.

Well I'm telling you by experience, the NX tranny is shorter than any other SR20 tranny so you need longer shafts, basically the small difference makes it so it'll only break in one way: Turn a corner hard and hit a bump and/or brake at the same time. I guarantee you your cv joint will break.

I know for a fact that the SER and NX tranny are exactly the same. Both are sitting in my garage right now. This is a fact, not a guess, I have rebuilt over a dozen of them now.

Did you watch the videos? Lts of turning and braking in there. No axle breakage.

Here are some pics ov SER and NX and G20 non LSD trannies in various stages of assembly/disassembly.

Well then how do you explain the fact that I got a longer CV joint and now everything is staying intact?

somebody correct me if I am wrong...but don't all Canadian G20's(P10) have the LSD??

Yup your wrong. Mine did'nt and Nismo18's doesen't have one yet.

oh...ok..I read that on some post in here...

I know my 92 G20 has it already

Hate to do it, but if the g20t's have lsd what kind of lsd is it? (I assume it isn't vlsd)
